Abstract
Process for coding binary image numbering signals to be stored on a recording medium and device for reading these signals. The process aims at protecting these signals from variations encountered during the transcription process onto a recording medium. This protection is obtained by selective inversion and repetition of predetermined parts of the binary signals. Application more specifically to an audio visual signal transmission apparatus incorporating a track jump pulse generating system, the images and the binary numbering signals of these images being recorded on a video disk.
