5.1 Channel
5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. It uses five full bandwidth channels and one low-frequency effects channel (the "point one"). Dolby Digital, Dolby Pro Logic II, DTS, SDDS, and THX are all common 5.1 systems. 5.1 is also the standard surround sound audio component of digital broadcast and music. All 5.1 systems use the same speaker channels and configuration, having a front left and right, a center channel, two surround channels (left and right) and the low-frequency effects channel designed for a subwoofer. History A prototype for five-channel surround sound, then dubbed "quintaphonic sound", was used in the 1975 film ''Tommy''. 5.1 dates back to 1976, when Dolby Labs modified the track usage of the six analogue magnetic soundtracks on Todd-AO 70 mm film prints. The Dolby application of optical matrix encoding in 1976 (released on the film ''Logan's Run'') did ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5 1 Channels (surround Sound) Label
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime.

Dakar
Dakar ( ; ; wo, Ndakaaru) (from daqaar ''tamarind''), is the capital and largest city of Senegal. The city of Dakar proper has a population of 1,030,594, whereas the population of the Dakar metropolitan area is estimated at 3.94 million in 2021. The area around Dakar was settled in the 15th century. The Portuguese established a presence on the island of Gorée off the coast of Cap-Vert and used it as a base for the Atlantic slave trade. France took over the island in 1677. Following the abolition of the slave trade and French annexation of the mainland area in the 19th century, Dakar grew into a major regional port and a major city of the French colonial empire. In 1902, Dakar replaced Saint-Louis as the capital of French West Africa. From 1959 to 1960, Dakar was the capital of the short-lived Mali Federation. In 1960, it became the capital of the independent Republic of Senegal. History The Cap-Vert peninsula was settled no later than the 15th century, by the Lebu peop ...

Digital Cinema
Digital cinema refers to adoption of digital technology within the film industry to distribute or project motion pictures as opposed to the historical use of reels of motion picture film, such as 35 mm film. Whereas film reels have to be shipped to movie theaters, a digital movie can be distributed to cinemas in a number of ways: over the Internet or dedicated satellite links, or by sending hard drives or optical discs such as Blu-ray discs. Digital movies are projected using a digital video projector instead of a film projector, are shot using digital movie cameras and edited using a non-linear editing system (NLE). The NLE is often a video editing application installed in one or more computers that may be networked to access the original footage from a remote server, share or gain access to computing resources for rendering the final video, and to allow several editors to work on the same timeline or project. Alternatively a digital movie could be a film reel that ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blu-ray
The Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc data storage format. It was invented and developed in 2005 and released on June 20, 2006 worldwide. It is designed to supersede the DVD format, and capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X. The name "Blu-ray" refers to the blue laser (which is actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs. The polycarbonate disc is in diameter and thick, the same size as DVDs and CDs. Conventional or pre-BD-XL Blu-ray Discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-l ...

Matrix Decoder
Matrix decoding is an audio technology where a small number of discrete audio channels (e.g., 2) are decoded into a larger number of channels on play back (e.g., 5). The channels are generally, but not always, arranged for transmission or recording by an encoder, and decoded for playback by a decoder. The function is to allow multichannel audio, such as quadraphonic sound or surround sound to be encoded in a stereo signal, and thus played back as stereo on stereo equipment, and as surround on surround equipment – this is "compatible" multichannel audio. Process Matrix encoding does ''not'' allow one to encode several channels in ''fewer'' channels without losing information: one cannot fit 5 channels into 2 (or even 3 into 2) without losing information, as this loses dimensions: the decoded signals are not independent. The idea is rather to encode something that will both be an acceptable approximation of the surround sound when decoded, and acceptable (or even superior) stereo ...

LaserDisc
The LaserDisc (LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as DiscoVision, MCA DiscoVision (also known simply as "DiscoVision") in the United States in 1978. Its diameter typically spans . Unlike most optical disc standards, LaserDisc is not fully Digital data, digital, and instead requires the use of analog video signals. Although the format was capable of offering higher-quality video and audio than its consumer rivals—VHS and Betamax videotape—LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and the inability to record TV programmes. It eventually did gain some traction in that region and became somewhat popular in the 1990s. It was not a popular format in Europe and Australia. By contrast, the format was much more popular in Japan and in the more affluent regions of Southeast Asia, such as Hong Kong, Singapore and Malaysia, and was the ...

Cinema Digital Sound
Cinema Digital Sound (CDS) was a multi-channel surround sound format used for theatrical films in the early 1990s. The system was developed by Eastman Kodak and Optical Radiation Corporation. CDS was quickly superseded by Digital Theatre Systems (DTS) and Dolby Digital formats. CDS replaced the analogue audio tracks on 35 mm and 70 mm film prints with 5.1 discrete audio. The 5.1 tracks were encoded using 16-bit PCM audio in a delta modulation compression which resulted in a compression level of 4:1. The audio channels in CDS were arranged in the same way that most current 5.1 systems with Left, Center, Right, Left Surround, Right Surround and LFE. ''Dick Tracy'' (1990) was the first film encoded with CDS. Not all films with CDS soundtracks used all 5.1 channels; some, such as ''Edward Scissorhands'' (1990), used only the 4 channels that were supported by Dolby Stereo. '' Universal Soldier'' (1992) was the last film encoded with CDS. The digital information was printed on the fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
