PROCEDURES FOR THE TRANSFER OF DIGITALISED STEREO-PHONE TONSIGNALS ON MAJOR RAIL FUNCTIONS

摘要

In order to transmit digitized stereophonic sound signals over channels, in particular radio channels, subject to interference, the invention proposes that transmission errors are detected at the decoder end and, if necessary, corrected or screened out. Most of the computer calculations necessary for the correction or screening out of the errors are carried out at the encoder end. The result of the computer calculations is transmitted in coded form as supplementary information to the decoder, which uses the transmitted result in the correction or screening out of errors.
