METHOD OF CODING THE DIGITAL INDEXING SIGNALS OF IMAGES STORED ON A RECORD CARRIER, DEVICE FOR READING THE SIGNALS SO CODED AND APPARATUS FOR TRANSMITTING AUDIOVISUAL SIGNALS COMPRISING SUCH A DEVICE

摘要

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.
