PROCESS FOR THE ADAPTATION OF THE CADENCY OF THE SIGN OF MOBILE IMAGES THE CADENCY OF THE APPARATUS AND DEVICE FOR THEIR REALIZATION

摘要

A method and apparatus are described for adjusting clock pulses of time-equidistant digital line scanning values of a moving-image signal present in a composite color video signal to a clock used in a digital transmission link by means of a moving-image coder. In the transmitting part (10) of the moving-image coder, self-identifying stuffing characters are inserted into the string of image scanning values if clock deviations are found. The identification may be carried out by means of an additional bit or, alternatively, by a special code word when this is first removed from the supply of image scanning values. In the receiving part (30) of the moving-image coder, the stuffing character is recognized and removed and the original character string is restored.
