Abstract
Reproduction accuracy of a digital signal, representing, for example, stereo audio signals, is improved by transmitting sample data which have been encoded to form transmission signals. The stereo audio signals are coded into sub(band) signals. Corresponding sub(band) signals of the stereo audio signals may be processed to obtain composite sub(band) signals, which are recorded on a record carrier. To identify whether corresponding sub(band) signals have been processed or not, a mode indicator control signal, indicating whether a corresponding sub signal of the at least two signal components have or have not been processed into a composite sub-signal, is also being recorded on the record carrier.
