Method of transmitting update information for a stationary video picture.

摘要

Finite audio and video signals are subjected to some digitalising encoding format and converted into blocks of audio and video words, respectively. For the transmission of these blocks via a compact disc the words are arranged in packets. Each packet has a packet head and a data field. Such a data field comprises either only audio words or only audio video words. The packet head indicates whether the associated data field comprises audio or video words. In order to transmit only changes in the picture in the case of, inter alia, quasi-stationary pictures, each block of video words is divided into a number of sub-blocks and an operational code is added to the beginning of each sub-block. This defines, inter alia, picture elements and the sub-block itself gives video words for these picture elements.
