Projection TV
Rear-projection television (RPTV) is a type of Large-screen television technology#Projection television, large-screen television set, television display technology. Until approximately 2006, most of the relatively affordable consumer large screen TVs up to used rear-projection technology. A variation is a video projector, using similar technology, which projects onto a Projection screen, screen. Three types of projection systems are used in projection TVs. CRT rear-projection TVs were the earliest, and while they were the first to exceed 40", they were also bulky and the picture was unclear at close range. Newer technologies include Digital Light Processing, DLP (reflective micromirror chip), LCD projectors, Laser video display, Laser TV and Liquid crystal on silicon, LCoS. They are capable of displaying High-definition television, high-definition video up to 1080p resolution, and examples include Sony's SXRD (Silicon X-tal Reflective Display), JVC's D-ILA (Digital Direct Drive I ...

British Broadcasting Corporation
The British Broadcasting Corporation (BBC) is a British public broadcasting, public service broadcaster headquartered at Broadcasting House in London, England. Originally established in 1922 as the British Broadcasting Company, it evolved into its current state with its current name on New Year's Day 1927. The oldest and largest local and global broadcaster by stature and by number of employees, the BBC employs over 21,000 staff in total, of whom approximately 17,200 are in public-sector broadcasting. The BBC was established under a Royal charter#United Kingdom, royal charter, and operates under an agreement with the Secretary of State for Culture, Media and Sport.

Plasma Display
A plasma display panel is a type of flat-panel display that uses small cells containing Plasma (physics), plasma: Ionization, ionized gas that responds to electric fields. Plasma televisions were the first large (over diagonal) flat-panel displays to be released to the public. Until about 2007, plasma displays were commonly used in large televisions. By 2013, they had lost nearly all market share due to competition from low-cost liquid-crystal displays (LCDs). Manufacturing of plasma displays for the United States retail market ended in 2014, and manufacturing for the Chinese market ended in 2016. Plasma displays are obsolete, having been superseded in most if not all aspects by OLED displays. Competing display technologies include cathode-ray tube (CRT), organic light-emitting diode (OLED), CRT projectors, AMLCD, digital light processing (DLP), SED-tv, LED display, field emission display (FED), and quantum dot display (QLED).

Liquid Crystal Display Television
A liquid-crystal-display television (LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold type of television display. LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ratio, and inferior color gamut. LCD TVs rose in popularity in the early years of the 21st century, and exceeded sales of cathode-ray-tube televisions worldwide from late 2007 on. Sales of CRT TVs dropped rapidly after that, as did sales of competing technologies such as plasma display panels and rear-projection television. History Early efforts Passive matrix LCDs first became common as portable computer displays in the 1980s, competing for market share with plasma displays. The LCDs had very slow refresh rates that blurred the screen even with scrolling text, but their light weight and low cost were major benefits. Screens using reflective LCDs requ ...

Sound Bar
A soundbar, sound bar or media bar is a type of loudspeaker that projects audio from a wide enclosure. It is much wider than it is tall, partly for acoustic reasons, and partly so it can be mounted above or below a display device (e.g. above a computer monitor or under a home theater or television screen). In a soundbar, multiple speakers are placed in a single cabinet, which helps to create stereo sound and surround sound effect. A separate subwoofer is typically included with, or may be used to supplement, a soundbar. History One of the earliest attempts at a soundbar was the TeleSound Model 1300, marketed by TeleSound, Inc., in 1980. The TeleSound comprises a single wide enclosure with two 5-watt loudspeakers spaced 12 inches apart. Connecting a television set's mono output to the TeleSound via a 3.5 mm audio jack allows viewers to watch television in simulated stereo. Alternatively, separate left and right audio jacks allow for true stereo playback from LaserDis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SRS Labs

Sound Retrieval System
Sound Retrieval System (SRS) is a patented psychoacoustic 3D audio processing technology originally invented by Arnold Klayman in the early 1980s. The SRS technology applies head-related transfer functions (HRTFs) to create an immersive 3D soundfield using only two speakers, widening the "sweet spot (acoustics), sweet spot", creating a more spacious sense of ambience, and producing strong localization cues for discrete instruments within an audio mix. SRS is not a Dolby Pro Logic, Dolby matrix surround decoder but works with normal stereo recordings. History Initially Hughes Aircraft, for whom Klayman was doing acoustic consulting at the time, offered a standalone SRS audio processor, as well as licensing the technology to Sony and Thomson SA, Thomson (RCA) for inclusion in their products. In the early 1990s, Hughes sold off its non-aerospace-related holdings, and a group of entrepreneurs formed SRS Labs to acquire the SRS technology. Many TV sets employ built-in SRS to make t ...

Surround Sound
Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener ( surround channels). Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three ''screen channels'' of sound that played from three loudspeakers (left, center, and right) located in front of the audience. Surround sound adds one or more channels from loudspeakers to the side or behind the listener that are able to create the sensation of sound coming from any horizontal direction (at ground level) around the listener. The technique enhances the perception of sound spatialization by exploiting sound localization: a listener's ability to identify the location or origin of a detected sound in direction and distance. This is achieved by using multiple discrete audio channels routed to an array of loudspeakers. Surround sound typically has a listener location ( sweet ...
