Abstract

Bus system (1, 2, 3) for a television signal processing device for transferring video data (d8) of at least one video data source (8) and/or supplementary data (d10) of one or more supplementary-data sources (10) between a transmitter (1) and a receiver (3) by means of a bus (2), wherein at the transmitter end (1), a single data stream (d2) for the bus (2) is formed from the video (d8) and/or supplementary data (d10) by means of an interface circuit (4). The interface circuit (4) combines the video and/or supplementary data, source by source, into blocks (db; db1, db2) following each other successively in time and containing identification data (dk; sk, ik) for start and end, or start and length, and content identification, and transfers the blocks serially.
