Digital coding process for recording sound channels with a television signal and apparatus realizing this process










Image Number 2 for United States Patent #4314369.

In an audiovisual signals diffusion apparatus, a digital coding process for protecting coded digital sound signals alternately recorded with video signals against alterations or deteriorations encountered during the transcription process onto a recording carrier or support, comprising the steps of selectively protecting signals representing low analog levels against large erroneous variations, transmitting several times the thus protected signals and garbling the different bits of successively transmitted digital signals, said process being compatible with the multiplexed recording of several sound channels.
