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

the invention relates to a method for coding binary image signals) intended to be stored on a record carrier and reading device thereof.;the process according to the invention is intended to prevent such signals from the alterations encountered in the process of recording on a recording medium.this protection is achieved by inversion (1 to 20) and selective repeat in predetermined sections (20) to 20 (5) of the binary signals.;application, in particular to a device for distribution of audiovisual signals including a pulse generator control system (100), a track jumpthe images and the binary image signal is recorded on the numbering of the videodisc.
