Abstract

In order to modify, in selected regions, the information content of a stream of digital video data, processed according to MPEG2 standards which is to be broadcast via terrestrial transmitters or cables, predetermined data packets in the selected regions, which are identified by their PID (packet ID) are extracted from the data stream and are replaced by data packets with a different information content or by blank packets.
