Verfahren und Vorrichtung zum Codieren eines zeitdiskreten Stereosignals

摘要

A process for coding a time-discrete stereo signal having a first and a second channel (R, L) makes it possible to scale stereo coding. A monosignal (M) is first formed from the stereo signal, then coded, and the coded monosignal is transmitted in a bit stream. Finally, the coded monosignal is decoded again and stereo information is formed on the basis of the coded/decoded monosignal (M') and of the first and second channels (R, L). This stereo information is coded and also written in the bit stream to yield a bit stream with a completely coded monolayer and a layer with coded stereo information.
