Abstract:
A 3-channel encoder and corresponding decoder is disclosed for encoding a 3-channel signal into a transmission signal which is backwards compatible, so that prior art one channel decoders are capable of decoding the transmission signal into a mono signal and 2-channel decoders are capable of decoding the transmission signal into a compatible stereo signal. Further, a 3-channel decoder is disclosed for decoding the transmission signal into a 3-channel signal. Also a 4-channel encoder is disclosed for encoding the 4-channel signal into a transmission signal which is backwards compatible, so that prior art one channel decoders are capable of decoding the transmission signal into a mono signal and 2-channel decoders are capable of decoding the transmission signal into a compatible stereo signal.
