METHOD FOR OPTIMIZING THE TRANSMISSION OF SIGNALS

In a method for optimizing the transmission of signals, especially video signals, over a channel with a predetermined channel data rate after source encoding for data reduction and channel encoding, in which redundancy is added to the source-encoded signals for error control protection, at least one quality parameter of the transmitted and decoded signals is measured. As a function of the measured quality parameter, the relationship between the source accuracy of the source encoding and the added redundancy is changed in opposite directions to optimize the transmission.
