The invention relates to a system and method for the generation of television channels and which allows the generation of the same by the processing and selection of designated packets of data from multiple data transport streams (10), with each transport stream including numerous packets of data. In each transport stream the packet of data is identified by the allocation of a packet identification Code (PID) and each is held in the transport packet which is transmitted as part of each transport stream. In accordance with the invention, and in order to prevent errors and inaccurate packet selection, a Transport Stream Identification Code (TSID) is allocated to each of the transport streams of data received. Typically the TSID is located in the transport packet for each transport stream of data. In the selection of a packet of data, the appropriate TSID is referred to identify the appropriate transport stream and the PID then referred to identify the packet of data from that transport stream. <IMAGE> |
