Dolby Surround


Dolby Surround is an early home embodiment of Dolby Stereo. Video production companies are licensed to make VHS tapes and laserdiscs that contain the same 4-channel matrix encoded information that was contained on the original motion picture release. Consumer electronic companies are licensed to make consumer surround decoders that reproduce these 4 channels in the home. It has a passively derived center channel and is not to be confused with Pro Logic, which we will cover soon.
