In Reply to: Question on Dolby Digital (AC3) - is it recorded on videotape? posted by John C. - Aussie on May 1, 2004 at 16:50:40:
Pro-Logic is a decoding format, so it's not recorded on the tape. What's actually recorded is an analog Dolby Surround signal. It can be processed by various matrix surround decoding technologies, such as: Dolby Surround, Dolby Pro-Logic, Dolby Pro-Logic II, Dolby Pro-Logic IIx, Circle Surround, etc.The Dolby Digital / AC-3 signal has to be turned into an analog signal (D to A process) before it can be recorded to tape. However, there were some experiments early on to get Dolby Digital / AC-3 encoded onto tape via S-VHS decks. Since nothing ever came of it, I guess it either was abandoned or didn't work too well.
