What is the difference between DTS, Dolby Digital and SDDS?
A. All three are major manufactures of digital playback equipment for motion pictures, but all three use different processes of data retrieval. • DTS use a time code stored on the film to synchronise playback data from a computer based optical and or hard drive into 6 discrete channels. • Dolby use a LED scanner to retrieve encoded data from between the sprocket holes of the film and playback into 6 discrete channels. • Sony Dynamic Digital use 2 LED scanners to read 2 encoded data soundtracks on each side of the film to replay into 8 discrete channels. There is no domestic equivalent of the Sony processor and it is regarded through out the industry as the supreme playback unit.
