Your old TV isn't good enough to watch movies, TV shows, or sports events on anymore. You wish you could do more with the media you have at home. Home theater words can be hard to understand. If you've ever been around a home theater expert, you may have felt like you didn't know as much as they did. It all depends on how you talk about things. I'll teach you how to talk like a pro about home entertainment systems. To start, you should just get familiar with the main ideas. The parts of any good home theater system will be easy to recognize. This setup includes a video source, a receiver, surge protectors, a sound system, cables, and screens. In the sections that follow, each of these topics will be looked at in more depth. 4K resolution 4K resolution means that there are about 4,000 pixels across the width of the screen. Several different 4K resolutions are often used in digital television and digital filmmaking. The most common 4K standard for TV and consumer media is 3840 2160. The movie projection industry, on the other hand, uses 4096 2160. Active Subwoofer A subwoofer with an amplifier built right into it. This form of subwoofer should get a line-level preamp signal from an AV receiver. This means that the signal hasn't been amplified yet. Then, the subwoofer amplifies the sound signal and sends it to the speaker. Active subwoofers usually have basic volume and equalization controls on the unit that let you change the output volume and tone. Most subwoofers made for home theater use will be active. A passive subwoofer, which is less common, is the other choice. Amplifier A loudspeaker or subwoofer needs an amplifier to get power. It takes low-voltage (line level) audio (usually less than 2 Vrms) and sends it out with enough power to power a loudspeaker. An amplifier can be a part of an A/V receiver, a stand-alone product, or it can be made correctly into a subwoofer or speaker cabinet. Aspect Ratio The aspect ratio tells us how a TV picture looks. When you divide the width of an image by its height, you get its aspect ratio. For example, the shape of a TV picture is usually 4:3. This means that there are four units across and three units down. When you divide 4 by 3, you get 1.33. So, a 4:3 image has an aspect ratio of 1.33:1, which means it is 1.33 times wider than it is long. If you look at the back of a DVD case, you can see what the film's aspect ratio is. It may say 4:3 or it may say 1.33:1 – or both! 1.78:1 is the aspect ratio of a 16:9 HDTV picture. AV Receiver An AV receiver serves as a switcher for numerous input sources and an amplifier/processor for surround sound systems. A receiver makes it easy to switch between different input sources, like satellite TV boxes, game consoles, and DVD/Blu-ray players. The AV receiver has both audio and video connections for all of the devices that can be plugged in. Afterward, the receiver transmits the video signals to the screen (such as an LED TV) and the audio signals to the sound system. An AV receiver is different from such an AV amplifier because it has a radio tuner built in. A 5.1/7.1 surround sound audio signal will also be processed by the receiver and sent to the linked surround sound speaker system. Bandwidth The most data that can be sent through an Internet connection in a certain amount of time. Bandwidth is often confused with internet speed, but it's actually the amount of data that can be sent over a connection in a certain amount of time, measured in megabits per second (Mbps). Bass trap Bass traps are a type of acoustic treatment that helps get rid of problems with low frequencies in a room. They are made to help fix a room that has a "boomy" sound. This "boomy" effect happens when the corners of a room (where a wall meets another wall or a wall meets the ceiling), which are more solidly built, reflect these low frequencies and create standing waves. In the case of standing waves, the amplitude of a low-frequency peak is equal to the amplitude of a corresponding trough, and the distance between diagonal corners is also equal to the (or harmonic of the frequency at half, quarter length etc.). Black Level Video black level is the brightness level of the darkest (blackest) part of an image or the brightness level at which no light comes out of a screen, making a pure black screen. In general, video displays need to be calibrated so that the black they show matches the black in the video signal. If the black level is not set correctly, visual information in a video signal could be shown as black, or black information could be shown above black information (gray). Different TV standards have different amounts of voltage for the black level. The black level in PAL is the same as the blanking level, but the black level in NTSC is about 54 mV higher than the blanking level. Blu-ray Disc A Blu-ray disc is similar to a DVD in that it is an optical storage disc. Blu-ray is the same size as a CD or DVD, but it can't be played in a regular CD or DVD player. A Blu-ray disc is better than a dual-layer DVD because it can hold about six times as much information. This means that a Blu-ray disc can hold high-resolution video and audio files that wouldn't fit on a DVD. So, a movie can be watched in 1080p high-definition video and heard in uncompressed multi-channel Dolby TrueHD or DTS-HD Master Audio. If you want, you can think of it as a high-definition DVD. bps (bits per second) Bits per second (bps) or bits per second (bit/sec) is a common way for computer modems as well as transmission carriers to measure how fast data is sent. As the name suggests, the speed in bits per second (bps) is the same as the number of bits sent or received every second. Bit rate, sometimes called bitrate or the variable R, is the number of bits processed in a given amount of time expressed as a decimal fraction of a second. Most of the time, these terms are used in the fields of data communications, telecommunications, and computer science. Sometimes, bigger units are used to show faster data speeds. One kilobit per second is equal to 1,000 bits per second (bps), and one megabit per second (Mbps) is equal to one million bits per second, or 1,000 Kbps. Burn-in The term "Burn-in" refers to a process in which semiconductor parts are put through extreme stress tests to find any early problems caused by bad materials, design, or manufacturing. Burn-in systems are used to do these tests, and the test conditions are set up to be like real-world situations. Coaxial Coaxial cables are used to send different radio, video, and audio signals. It consists of a solid conductor core, a layer of plastic insulation, another thin layer of conductor, and then a layer of plastic insulation on the outside. For a digital sound coaxial connection, it is best to use a 75-ohm coaxial cable to make sure that the signal is sent correctly. At each end of a coaxial connection for digital audio, there will be an RCA plug. Codec The word "codec" stands for "coder-decoder." In home theater, a codec is a term for different digital compression algorithms, like the ones used to compress and decompress audio on DVD as well as Blu-ray discs. So, we can talk about the DTS 5.1 codec or the Dolby Digital codec. Color Depth The color model of RGB is used by most TVs to show a picture. Here, each pixel's color is made up of different amounts of red, green, and blue. The number of bits used to describe each color for each pixel in a video is called its "color depth." About 16 million colors can be made with 8-bit color. About 1 billion colors can be made with 10-bit color. About 68 billion colors can be made with 12-bit color. 8-bits are usually used for each color in consumer video. This is how standard Blu-rays work, for example. 4K UHD Blu-ray uses 10-bit color, and the extra colors help with HDR content in particular. Ultra HD also allows for 12-bit color, but most TVs only have 8-bit or 10-bit color right now. Color depth and chroma subsampling are two terms that people often mix up. But they are not the same. Contrast Ratio The contrast ratio is defined as the number of sRGB bits in the brightest (white) and darkest (black) color signals which a panel can output. It is written as a ratio and tells the number of times brighter the white level is than the black level. For example, a contrast ratio of 2000:1 means that the white level is 2000 times brighter than the black level. Theoretically, a higher contrast ratio is better because it makes the whites whiter and the blacks darker. This makes the image look more real and detailed, especially when it's dark. People often say that an OLED TV has a contrast ratio of 1. This is because the black levels are perfect, which is measured as 0. But don't let the numbers alone fool you too much. In the real world, it doesn't always mean much. If you put a TV in a room with a lot of light, the picture won't show its full contrast ratio because the light will wash out the picture. So, if you watch movies in a dark room, the contrast ratio is more important. Just know that this is something to keep an eye out for. Center Channel Even though it's not the most essential speaker in a home theater system, the center channel speaker gets used the most. It usually has all of the dialogue and most of the effects that happen in the center. For optimal results, position the center channel speaker either below or above your screen. The only time this isn't true is when the projector screen has holes in it. In this case, the center channel is put right behind the screen. Coaxial Coaxial can refer to any cable that has a center “hot” pin with a surrounding shield. The Coaxial cables can be used for antenna or cable TV, but they can also refer to RCA style cables used to connect analogue outputs and inputs on audio devices. Coaxial can also refer to speakers where one driver (typically a tweeter) is located in the middle of another (typically a midrange driver). Component Video People often mix up "component video" and "RGB," since the cables are usually red, green, and blue. Component video is being phased out because of copyright concerns from content providers and film studios, despite the fact that it can transmit standard and high definition material in analogue form. Component video is also called Y/Pb/Pr, which means that the luminance (Y) information has been sent on one cable and the red (Pr) and blue (Pb) information is sent on the other two.  Composite video Composite video is a type of analog video signal that sends a single channel of standard-definition video (525 or 625 lines, usually). Video information is encoded on a single channel, but unlike high-quality S-Video, which uses two channels, or the even higher-quality component video, which uses three channels (three or more channels). Audio is sent over a separate connection in all of these video formats. CRT (Cathode Ray Tube) CRT (Cathode Ray Tube) TVs use the CRT to project each of the primary light colors red, green, and blue. A phosphor-coated screen on the back of the tube is painted with lines by an electron gun. The scan lines have been aligned because then they merge into one picture. Burn-in can happen to CRT models. Digital Tuner The DTV converter box has the digital TV tuner that an older analog TV needs to be able to pick up digital TV signals from the air. Digital or high-definition TVs include an internal digital tuner that receives broadcast digital TV signals. Unless you are one of the few people who still uses a CableCard, the set-top box you got from your cable or satellite provider likely came with a digital TV tuner. The CableCard thus acts as the tuner. Distortion Distortion happens when the audio signal is too strong for the medium being used to send or record it. Interference is anything that isn't supposed to be in an audio transmission and changes the recording or sound from how it was meant to be. Distortion happens when the shape of the output is different from the shape of the input, but the loudness and dynamics are the same. DLP The DLP Digital Light Processing (DLP) chipset family uses an optical micro-electro-mechanical system and a digital micromirror device. Digital light processing is used for both traditional static displays and interactive displays, as well as non-traditional embedded applications like medical, security, and industrial uses (DLP). Digital signage, TVs with front projection, and TVs with back projection all use DLP technology. Schools and businesses often use front projectors. It's used in about 85% of all digital movie projections, and some 3D printers use it as a light source to cure resins, which makes it possible to make solid, three-dimensional things through a process called "additive manufacturing." Dolby Atmos A type of surround sound which uses objects to create a three-dimensional sound field by integrating the impacts of height and individual speakers. Instead of the front left, front right, center, surround left, surround right, and LFE channels that are used in a standard 7.1 surround sound setup, Dolby Atmos can use up to 128 separate audio objects. The mix was done on a 10-channel, 7.1.2 bed, so any 5.1 or 7.1 system should be able to play it well. Then, for systems that work with Dolby Atmos, an extra 118 things can be added around the sound field. Dolby Pro-Logic Dolby Pro Logic, the first of Dolby's surround sound formats, lets you separate the left and right channels from a stereo or Dolby Surround soundtrack to make a 4.0 surround output. The left and right front stereo speakers, the center channel, and the left and right rear mono speakers all make up these four channels. When it came out, this was a big step forward, but now we might expect at least 5.1-channel surround sound. Dolby TrueHD A way for Blu-ray discs to use Dolby's multi-channel audio standard. Dolby TrueHD uses lossless compression to fit more data on a CD. The audio you hear, on the other hand, is not compressed, so it sounds just like the new studio master recordings. The dynamic range is great all the way from the lows to the highs. I love it! But if your audio setup isn't very good, you won't get much out of it. It's a rival to Blu-ray discs' DTS-HD Master Audio. You might be able to use either format or both. Dolby Vision This technology, called "Dolby Vision," came out for the first time in 1997. The primary advantage over regular HDR is that information about how each scene should be shown can be sent to the TV scene by scene. It could also change based on what each TV can do. You might be able to use a firmware update to make your current gear work with Dolby Vision. DTS-HD Master Audio Multi-channel audio format made by Digital Theater System (DTS) that can only be played on Blu-ray discs. In DTS-HD Master Audio, the audio data is compressed so that it can fit on the CD, but what you hear is the uncompressed audio. The sound is reproduced just as it was on the studio master tapes. The dynamic range is good, the bass is strong, and the highs are clear and bright. It's great, but you'll need a good sound system to get the most out of it. On Blu-ray discs, it goes up against Dolby TrueHD. Either choice is possible. DTS:X DTS:X is an object-based surround sound format made by DTS. Like Dolby Atmos, DTS:X lets you create a 3D sound field by using both regular surround sound speakers and speakers in the ceiling. The sound in a DTS:X presentation will change based on how the speakers are set up in the room. This makes sure that you can enjoy DTS:X sound with different kinds of speaker setups. You just need to make sure your AV receiver can decode DTS:X soundtracks. DVD Audio DVD Audio is a digital audio format that is used on DVDs. Because a DVD has more space than a CD, it can store and play back better quality music than a CD. DVD-Audio can play high-resolution stereo files of up to 192 kHz/24 bit and 5.1 surround sound files of up to 96 kHz/24 bit. DVR A digital video recorder (DVR) is a piece of computing equipment that may record video and save it to a local or remote mass storage device (MSD) such a hard drive, USB flash drive, Secure Digital (SD) memory card, solid-state drive (SSD), or network. Digital video recorders, portable media players, TV gateways, and set-top boxes having direct to disk recording capabilities are all included in this broad category. Digital video recorders (DVRs) are often just computers that are hooked up to a video recording device. In these cases, the software needed to record video is already built into the DVR. Many digital video recorders (DVRs) are considered consumer electronics. In some countries, like Canada, these devices are also called "personal video recorders" (PVRs). Professional film and video production could use similar small devices with built-in 5-inch diagonal displays and SSD support. These recorders usually don't have the same limitations that cameras' built-in recorders do, so they can support more codecs, record for longer periods of time, and have higher bitrates. Dipole Speakers Dipole speakers have two speaker drivers in the same cabinet. This means that the sound can be sent in two different directions. Simply put, they work best as surround speakers in a 5.1 or 7.1 system. When one part is trying to push, the other side is pulling, so the signal from dipole speakers is out of phase and hard to find. For this type of speaker to work well, it needs to be put in the right place. Bipole speakers, which can be set up in a wider variety of ways, are another option. Driver This is the part of the speaker that moves and makes noise. Most of the time, larger drivers can reproduce lower frequencies, while smaller drivers may be able to reproduce higher frequencies. They work by quickly squeezing the air ahead of them and moving it. EDTV The Consumer Electronics Association uses the term "enhanced-definition television" (EDTV) to market a subset of HDTV hardware and software. This phrase refers to devices that support progressive scan, which is also known as 480p (NTSC-HQ) and 576p (PAL/SECAM). Interlaced scanning, which is called 480i (NTSC) and 576i (PAL/SECAM), is the opposite of this (PAL, SECAM). EDTV doesn't have to be about extreme activity. Equalization A circuit in a piece of audio equipment called an equalizer (EQ) changes the signal in a certain frequency range. There are hardware equalizers, but so many contemporary home theater systems have had this function built directly into the software, whether automatically or with sliders and slider sets that the user can control. The tone control is one of the easiest ways to change the sound. It usually has a bass as well as treble slider. The full range of equalizers includes parametric EQs, which let you change the width of the band, the center frequency, and also the amount of gain or trim, as well as graphic EQs, which let you choose a band and change it to affect a certain frequency range, and parametric EQs, which let you change the width of the band, the center frequency, and the amount of gain or trim. Frequency This is the technical term for how often a force from the outside makes air move. In home theater and music, we talk about a tone's or sound's frequency range or frequency band. Tweeters are in charge of making high-frequency sounds, while regular drivers and woofers are in charge of making low-frequency sounds. The upper and lower limits of a band where any particular frequency can be found in a linear or logarithmic form are called the "frequency range." Even though the average individual can listen to frequencies between 20 Hz and 20 kHz, by the time they hit their 30s, most people's listening has already peaked around 15-16 kHz. We usually "feel" frequencies below 20 Hz rather than "hear" them. Flat Screen TV This type of display is also known as a "flat-screen TV." Contemporary flat-screen TVs are much easier to move around the room than CRT TVs, which are bigger and heavier. Because it is so thin, a flat-screen TV could even be mounted on the wall to save space. They can be as short as 10 inches or as long as 70 inches or more. LED and OLED are currently the most popular types of flat screen technology on the market. Plasma and LCD tv sets have both been replaced by newer technologies. Frame/Frame Rate During a recording, a video or film camera takes a new picture, or frame, at regular times. The frame rate of a camera is how many still pictures it can take in one second. A high frame rate makes sure that any movement in the picture looks smooth and natural. The frame rate for traditional film cinematography is 24 frames per second. A video's frame rate can be different in many places around the world. Most of Europe, such as the UK, uses a frequency of 50 Hz, or 25 fps/50 fps. In the United States and Japan, the standard is 30 frames per second and 60 fields per second, respectively. Some special broadcasts, like those of sports games, may use higher frame rates of 50/60Hz to better show fast-moving action. FPS Frames per second (FPS) is a measure of how well a video is recorded, played back, or played in a game. Frames per second (FPS) is a term that is often used when talking about video recording and playback. It measures the frame rate. Regarding 10–12 frames per second is about all our minds can handle. Whenever the frame rate is more than this, it looks like the picture is moving. The more frames per second (FPS) there are, the smoother the video seems to move. 24 frames per second is the norm for full-motion video. Different video formats have different frame rates (FPS). Lower FPS rates cause computer files to be smaller. HD DVD HD DVD stands for DVD with a high definition and/or density. Toshiba's high-density data storage optical disc format was comparable to Blu-ray. In comparison to standard DVDs, it can contain a lot more information, making it great for HD content. When major content producers abandoned it in favor of Blu-ray in 2008, it was officially retired. HDMI HDMI Means High Definition Multimedia Interface. A connection that allows for the transfer of digital audio and video. In today's world, this form of cable connection is the norm for AV equipment. The minimum need for a modern television or Blu-ray/DVD player should be one of these. You should utilize this connection instead of the component or SCART connections if possible. All digital video signals (including HD) and up to 8 channels of lossless digital audio may be sent via a single HDMI connection (including Dolby TrueHD and DTS-HD Master Audio – with HDMI 1.3). That's great news since it means there are fewer cords cluttering the space behind your TV. HDMI ARC/eARC In the case of HDMI, "ARC" refers to the Audio Return Channel while "eARC" refers to the enhanced ARC. Some of the HDMI ports on a TV, AV receiver, or sound bar may have the ARC designation. This allows the TV's sound to be played via the AV system's speakers. For this to function, the HDMI ports on both your TV and receiver/soundbar must be compatible. This may help streamline your network. This feature may eliminate the need for an additional optical connection while listening to in-TV audio, such as when using the Netflix or Amazon Prime Video app. If your TV doesn't have a digital audio out, this is a great alternative. Dolby TrueHD/DTS-HD Master Audio and Dolby Atmos are just some of the higher bitrate audio formats that can be sent over the newer eARC (Enhanced Audio Return Channel) standard. HDR High Dynamic Range is the abbreviation for this effect. Method of expanding an image's tonal range. Deeper blacks. More luminous whites. There should be a wider range of hues. Result? A more realistic image will result. To stream material from an HDR-capable Blu-ray player to an HDR-capable TV, you will need an AV receiver that also supports HDR. HDR is available in a number of flavors, including Dolby Vision, Hybrid Log-Gamma, HDR10, and HDR10+. A certain version may only be used if your whole hardware setup is compatible with it. HDR10 HDR10 is an open-source HDR format that is supported by a wide variety of devices. The current standard for both sources and displays. HDR10+ HDR10 with the latest improvements. It's similar to Dolby Vision in that it uses dynamic information to alter the contrast and color gamut based on the context of the current scene or frame. It's starting to appear more often in items from certain brands. HDTV High-Definition Television is abbreviated as HDTV. Compared to standard definition television (SDTV) and enhanced definition television (EDTV), high definition television (HDTV) delivers much sharper visuals. High-definition video signals have to include at least 720 vertical lines of information per frame when using progressive scan, or 1080 lines when using interlaced scan. Thus, both 720p and 1080i, and especially 1080p, are high-definition transmissions (also known as full HD). A 16:9 ratio is recommended for the film as well (widescreen). HDV When compared to SD video, high-definition video (HDV) is clearly the superior technology. When compared to regular video and older video formats, the file size, screen size, and quality of this newer format are all superior. Compared to standard definition video, high definition video allows for a wider range of technical factors to be adjusted. Horn A horn is a kind of high-frequency driver in which a guide in the form of a horn is fitted around a tweeter to direct the sound in a certain direction. Nearly often, the speaker itself serves as inspiration for the horn's design. Klipsch is responsible for bringing the horn's widespread use in live sound reinforcement to the home theater market. Integrated Amp This device is both an amplifier and a preamp, which means it can do both. A receiver usually has an AM/FM tuner and often has video switching functions to set it apart from an integrated amplifier. Impedance Impedance is the amount of resistance that a load, like a speaker, puts up against an amplifier. It does exactly what it sounds like it does. The total number of parts in a loudspeaker determines how much current the amplifier sends to the system. This is a function of how the speaker is made. Speakers with impedances that work well with amplifiers and make sound that is consistent across all frequencies were made with these things in mind. A speaker with a higher impedance will need a stronger amplifier to make sound in the same conditions. Image Resolution The size of an image is based on how many pixels were used to make it. This is what you get when you multiply the number of lines of vertical pixel data by the image's aspect ratio. HDTV needs at least 720 lines of pixels in the vertical direction, and the typical aspect ratio is 1.78. (16:9). So, 720 vertical lines times 1.78 (the aspect ratio) equals 1280. (horizontal lines). So, we can say that this 720p picture has a total of 921,600 pixels (1280 x 720). Depending on where a picture comes from, its resolution may change when it's sent to your TV. This is not the same as the TV's original resolution, which you can't change. Imaging The word "imaging" is similar to the word "soundstage" in that it describes how a set of speakers places sounds in the three-dimensional space in front of the listener. If your speakers have good imaging, you'll be able to place each instrument or sound effect in the virtual world exactly where it is. LFE Low Frequency Effects data from a movie is usually put on a separate track with a fixed sampling rate and a range of frequencies (20–120Hz). This is the extra channel that is added to a 5.1 or 7.1 audio track. It is often used to "sweeten" the low end of an effect or scene, like in explosions. Unless told otherwise, an A/V receiver will send signals from the LFE to the subwoofer output and send bass to any "Small" speakers. LED TV A kind of flat-screen TV that looks like an LCD. LED TVs light up their screens with light-emitting diodes (LEDs), while LCD TVs use compact fluorescent light bulbs (CFLs) (CCFLs). Even so, both of them have LCD screens. At first, there was a lot of confusion because not all TV manufacturers called their LCD TVs with LED backlights LED TVs. The term "LED TV" is being used more and more. LCD TV A word for a TV that has a flat screen. A liquid crystal display is what an LCD stands for. An LCD display is made up of "pixels" that are small pieces of liquid crystal and a backlight. The brightness of each pixel can be changed by sending an electric signal that changes the molecular structure of the liquid crystal. By using a color filter to separate each pixel into its red, green, and blue sub-pixels and then changing the amount of light that goes into each sub-pixel, a wide range of colors can be made. A TV image is made by changing the brightness and color of each individual pixel in real time. This technology is also used to make displays like computer monitors and projectors, as well as TVs and radios. Line Doubler/Tripler/Multiplier One way to improve picture quality, or PQ, is to show more horizontal lines on the screen. An anti-interlaced line-doubler stores both fields of each frame in a memory buffer and draws them all at once (i.e. progressive scan). Lumens The lumen (lm) is the unit of luminous flux in the International System of Units. Luminous flux is the total amount of visible light that a source gives off in a given amount of time (SI). A luminosity function is a model of how the human eye responds to different wavelengths of light, and this is how luminous flux changes from power (radiant flux). One lux is just the same as one lumen per square meter. Multi-zoom Multi-zone or multi-room refers to a system that can send sound to more than one room, either through the line level or through the speakers. This could be about the installation or the equipment. People often use the term "multi-zone" to mean that they can send sound from more than one place. Midrange Most of the sound spectrum is in the midrange, so it's not surprising that it's often the subject of discussion when judging speakers or other audio equipment. This is right in the middle of the sound spectrum, so the range of frequencies is from 600 Hz to 1.5 kHz. Here, the upper mids start, and you can hear frequencies up to 2.5kHz. MPEG MPEG is a video file format made by the Moving Picture Experts Group, the same people who made MP3 and MP4. Depending on how it will be used, it can use either MPEG-2 or MPEG-4 file compression. NanoCell A term used by LG to brand its top-of-the-range LED TVs. NanoCell TVs use a similar LED technology to QLED TVs. Therefore, they have an increased color range and better viewing angles compared to standard LED TVs. Native Resolution Native resolution is the number of actual dots on the screen. A display with a "Native Resolution" of 1280 x 768 has a width of 1280 pixels and a resolution of 768 pixels in the vertical direction. The physical dots a monitor can digitally copy are what make up its "Supported Resolution." The resolution that a flat-panel TV was made with. Input signals that are higher or lower than the native resolution must be upconverted or downconverted to show correctly. Optical Audio Connection A TOSLINK cable is a type of cable for both audio and video. A way for different devices to share digital audio signals. Put together to make a number of DVD players and video game consoles. The audio signal is turned into light and sent through an optical fiber cable. Using formats like Dolby Digital and DTS to get stereo and 5.1 surround sound data. OLED TV A type of flat-screen TV that doesn't use light-emitting diodes (LEDs) to make the picture. OLED stands for organic light-emitting diode. An OLED has an organic layer that gives off light when an electric current flows through it. Since these TVs don't need a backlight, they may be very thin and light. Also, it uses little power, has a large viewing angle, and has a good contrast ratio. People often say that they have the best picture quality that is currently available. Passive speaker For a passive speaker to be heard, its signal must be boosted by something else. A thing is "passive" if it can do its job without being plugged into a power source. There are crossovers and speakers that don't do anything. In a subwoofer or loudspeaker, a passive radiator is a driver and radiating surface that isn't connected to the amplifier's power supply but is nonetheless used to counteract the effects of the latter on the active driver or drivers. Passive Subwoofer This subwoofer needs a separate amplifier to work. This subwoofer needs to be hooked up to a home theater receiver in order to work. The subwoofer is useless as a speaker box on its own. Since the signal is amplified before it goes to the subwoofer, passive subwoofers usually don't have volume or tone controls. Subwoofers made to work with a home theater system often have electronics that work. Power Output The power output of an amplifier is the amount of power it produces in response to a particular voltage input. The results are usually given in watts, and there are many ways to measure the power output. OTA Over-the-air programming (OTA) refers to the many ways that devices like mobile phones, set-top boxes, electric cars, and secure voice communication equipment can get updates to their software, configuration settings, and encryption keys (encrypted two-way radios). Over-the-air new features have the benefit that they can be sent to everyone on the channel each from a single place, without users being able to say no. Pixel Pixel is Short for picture elements. A TV screen is made up of a grid of tiny dots, squares, and rectangles. Every one of them is called a "pixel." Each of these pixels can be set to show a different color and a different amount of brightness. When all of these dots, or pixels, come together, they make an image on the screen. If you stand very close to your TV, you might be able to see the pixels at work. The number of pixels used to make the display on your TV is its native resolution. Plasma TV Plasma TV is another word for a TV that has a flat screen. A plasma screen is made up of tiny pixels filled with gas and covered with phosphor. When an electrical signal is sent, gas and phosphorus react to make colors. By changing these colors, we can make a picture on the TV. Really clever, huh? Plasma TVs used to have the best picture quality, but all manufacturers stopped making them recently. Passive Speaker  For a passive speaker to be heard, its signal must be boosted by something else. A thing is "passive" if it can do its job without being plugged into a power source. Crossovers and speakers that don't use electricity don't need an active amplifier. A passive radiator is a driver or radiating surface on a subwoofer or loudspeaker that is not electrically connected to the amplifier. Instead, it is used to push back on the active driver or drivers. Progressive Scan A way to make the resolution of your TV look bigger is by scanning twice as many lines of image on the TV slowly (one after the other) (in succession). This way, you can see all of a frame's lines at once, which makes the picture look more uniform. This is done 30 times per second (fps) with NTSC (i.e. 30 fps). QLED TV LEDs are at the heart of Samsung's QLED TV technology. They are made with quantum dot technology, which is why they are called QLED. QLED TVs are better than regular LED TVs in a number of ways, such as having a wider range of colors, being brighter, and having wider viewing angles. But they are more expensive. Room Acoustics Room acoustics is a branch of acoustics that looks at how sound behaves in closed or mostly closed spaces. The acoustic "fingerprint" of a place can change the quality of a sound, whether it's speech, music, or noise. Since acoustics is about how sound waves interact with different surfaces, it makes sense that there are many different things going on in the acoustics of a single room. The general flow of sound waves in a space is affected by hard surfaces, loud sources, and high ceilings. RMS (Root Mean Square) A number that shows how something has changed over time. It's used with amplifiers to get a good idea of how much power they put out in watts. Root-mean-square (RMS) values are multiplied by the voltage and wattage measurements to get the power. The average power is more important than the peak power because it tells us more about how the amplifier will work in the real world. Refresh Rate The refresh rate of a TV is the number of times per second that the picture is "refreshed." The flicker will be less noticeable in fast-moving scenes if the image is updated more quickly. Because of differences in technology, this number will be a little off in different parts of the world. Interlaced TV in PAL countries has a frame rate of 25 fps, and each frame has two drawing passes. So, the rate of refreshment is written as 50Hz (25 x 2). (25 x 2). In the United States and Canada, the standard refresh rate is 59.94 hertz (Hz), which is the same as 29.97 frames per second (fps) (29.97 x 2). These refresh rates came from using interlaced scan pictures, but when progressive scan pictures were used instead, they stayed the same. Some new TVs now have refresh rates of 100 or 120Hz. Some say that digital signal processing can be used to get even higher refresh rates. RCA Plug RCA Plug is also called phono plug. These ports are a standard for connecting audio and video and can be found on many different kinds of electronics (DVD players, TVs, etc.). The red and white plugs are for stereo audio, the yellow plug is for video, and the red, green, and blue plugs are for component video. Digital audio links that use coaxial cables are also often used. Rear Projection A TV system that uses CRT, DLP, or LCD technology to project the image onto a mirror inside the cabinet. Some video projectors can flip the picture when used with a screen that projects from the back. RGB (Red Green Blue) The RGB color space is used by both the digital video camera and the RGB gun on a CRT. It is a generic color space with a high bandwidth that combines both color and black-and-white data. Most of the time, RGB is not good for sending or compressing (see also YCbCr) (see also YCbCr). Screen Gain Gain is a measure of how reflective a projection screen or other projection surface is. The gain shows how much light the screen tends to reflect than a normal white (magnesium oxide) board. Sensitivity A number that shows how much sound a speaker can make with a certain amount of electricity. Most of the time, the sensitivity of a speaker is measured in decibels of sound pressure level (SPL) at one meter from the speaker when it is being powered by one watt (2.83 volts at eight ohms). This test usually uses a certain frequency range, but this varies from manufacturer to manufacturer. Soundbar This line of speakers meant to go along the top or bottom of a TV. The goal is to improve the sound of the TV without having to set up a separate AV receiver and sets of speakers for surround sound. Most soundbars will use audio processing techniques to make it sound like there are more speakers there than there actually are. Most of the time, it is an active speaker that can be wired directly into the audio output of a TV. SDR This is short for "SDR," which stands for "Standard Dynamic Range." Standard definition (SDR) video has a much smaller dynamic range than high dynamic range (HDR) video. A standard dynamic range (SDR) TV can't play HDR content because it needs a higher level of brightness, contrast ratio, and color spectrum. SDTV "SDTV" is short for "Standard Definition Television." Standard Definition Television (SDTV) doesn't have as good of a picture as EDTV or HDTV (HDTV). Each frame of a standard definition video stream has either 480 (in North America) or 576 (in Europe) lines of information that can be seen from the top down. So, you might see a 480i (480 lines, interlaced) or 576i (576 lines) SDTV broadcast (576 lines, interlaced). Both HDTV and EDTV are better than standard definition TV in terms of picture quality. Subwoofer One that can play bass notes that are very low. This item is often called "sub" for short. A subwoofer is a low-frequency speaker that is connected to an AV receiver as part of a surround sound speaker system. But you only need a stereo amplifier to listen to music on one. You may get much better bass performance in your room if you use a speaker whose only job is to play low-frequency sounds (also known as the LFE track). If you get rid of your subwoofer, your surround speakers can also sound better. The neighbors can't stand it! Surround Sound The process of sending sound to many different places. Almost all of the sound we hear on TV and radio is stereo, which means it was recorded and mixed to be heard on two speakers in front of you. Surround sound can help people understand where sounds are coming from, both in the theater and at home. Think about the six speakers in a 5.1 surround sound system as an example. Typical home theater setups have left and right front speakers (or stereo speakers), a center channel for speech, left and right surround speakers (behind you), and a subwoofer (for bass). Two more speakers are in the back of the room as part of the 7.1 speaker set-up. Screen-door Effect On cheaper LCDs, you can sometimes see the grid of colorful pixels that make up the image. This makes it look like you're looking at the picture through a screen door. Surround speakers Surround speakers are also called back speakers or back effect speakers. In a home theater system, the surround speakers are in charge of making background noise. In a 5.1 setup, there are two surround speakers. In a 7.1 setup, there are four. If you like to watch movies at home, you need a surround-sound system. A soundbar just can't compare to a multi-channel system, whether it's 2.1, 5.1, or Atmos 5.1. When there are a lot of people around, it's easy to hear how the bigger and more interesting sound is better. SVGA Super VGA, or SVGA, is a group of resolutions and interfaces for computer monitors that were made to improve on IBM's VGA specification. The Video Electronics Standards Association (VESA) created this display standard, which has a higher resolution than that of the 640 x 480 Video Graphics Array (VGA) standard. The computer can show up to 16 million different colors, depending on its hardware and memory. S-Video S-Video is an analog video transmission format with 525 or 625 lines of resolution that is used to send standard definition video. It is also known as separate video, Y/C, and, incorrectly, Super-Video. When luma and chrominance are put on their own encoding channels, the picture quality is better than with composite video, which puts all of the video information on a single channel. It also gets rid of some of the things that make composite video look bad, like "dot crawl." The picture quality of S-Video is better than that of composite video, but it can't compare to the three-channel encoding and higher color resolution of component video. THD To quantify the degree of harmonic distortion in a signal, we may calculate its total harmonic distortion (THD or THDi), which is the quotient of the powers of all harmonic components over the power of the fundamental frequency. The related phrase distortion factor is occasionally substituted for it. Of audio systems, lesser distortion implies the components in a loudspeaker, amplifier or microphone, or other equipment generate a more accurate reproduction of an audio recording. Throw Distance The throw distance of a projector is the horizontal distance between the projector and the screen. It is expressed as a ratio describing the distance to the screen in proportion to the width of the screen. The projector's lens determines the device's throw ratio. THX Whether it's understanding the exact location of enemy gunfire or relishing the moment as you stand in the heart of an arena, the THX Spatial Audio App offers superior 7.1 surround sound with precision‌ and accuracy to make your game come alive. TOSLink The Toshiba Optical S/Video Link (TOSLINK) is a common kind of optical fiber plug. [4] Commonly used in consumer audio equipment (via a "digital optical" socket), optical audio transmits a digital audio signal from a source device (like a CD player or DVD player) to a destination device (like an AV receiver) that can decode the signal. This signal can be two channels of uncompressed lossless pulse-code modulated (PCM) audio or compressed 5.1/7.1 surround sound (like Dolby Digital or DTS Surround System). Lossless versions of Dolby TrueHD and DTS-HD Master Audio, as well as more than two channels of PCM audio, cannot be sent through TOSLINK due to its limited bandwidth. Tweeter A loudspeaker intended to reproduce high frequencies - commonly in the area of 2 kHz to 20 kHz. The high-frequency sound is reproduced by the tweeter, and the low-frequency sounds are reproduced by the woofer, both of which are found in a standard bookshelf speaker. Upscaling Upscaling means modifying a low-quality video feed to a higher resolution. Scaling video signals from one resolution to another is what a video scaler does. For instance, a DVD player may play an SD movie (480 lines NTSC, 576 lines PAL) and upscale this picture to 720 (or 1080) vertical lines to match the resolution of an HD monitor. When applied to a high-definition TV or projector, this method may vastly improve the visual quality of regular DVDs. In this scenario, the DVD player or the TV/projector, whichever has the superior video scaler, will provide the best results for the upscaled video. Due to its dedicated nature as a video display device, the TV will often include a more effective scaler. UHDV Both 4K UHD and 8K UHD are digital video formats with a 16:9 aspect ratio, and both are used in modern ultra-high-definition television. The resolution of 38402160P is considered to be UHD (Ultra High Definition). Basically, this implies that an Ultra High Definition (UHD) TV has a higher pixel density. The result is improved picture quality on the television. Because of the greater screen size of UHD TVs, viewers may move closer to the screen without diminishing the quality of the image. UMD Sony's optical disc format, Universal Media Disc (UMD), was designed for use with the PlayStation Portable mobile gaming and entertainment system but has since been phased out. It has a storage capacity of up to 1.8 GB, making it suitable for storing media like games, movies, and music. VGA Connector A system for transmitting video in analog form. The 15-pin D-type connector is the standard for this sort of port on electronic gadgets. Although its primary use are on PCs and projectors, several modern flat panel displays still have USB ports specifically for connecting laptops. Viewing Angle Viewing angle, in the context of display technology, refers to the maximum angle from which a display may be seen without compromising image quality. The precise term for this angular range is a "viewing cone," which encompasses many different possible perspectives. A display's viewing angle may be thought of as either the angular range in which the display can be seen well, or as the angle of usually acceptable viewing, such as a twelve o'clock viewing angle for a display suited for viewing from above. VRR (Variable Refresh Rate) "VRR" refers to the ability to change the refresh rate of a display. Section of the HDMI 2.1 standard. A VRR-capable display will automatically adjust its refresh rate to match the data coming from the graphics card. Gamers will find this to be of special value.
