ABSTRACT:
A method for the digital transmission of coded video signals with a fixed number of binary digits per frame dot, wherein each line of the video signal comprises a line synchronization word multiplexed during the line fly-back period, comprising using as line synchronization-word a pseudorandom sequence the self-correlation function of which is such that the synchronization word can be detected at the receiving equipment within a window of at least 3 binary digits, and stuffing each line of the video signal by eventually adding or subtracting one binary digit during the line flyback period at a fixed location in relation to the line synchronizing word.
