ABSTRACT:
In DVB/MPEG transport streams, the PID specifies the assignment of the packets to the different elementary streams. For reproduction of the elementary streams, for instance by a set-top box with outputting via the screen of a television set, the packets of the desired program have to be selected from the transport stream by means of the PIDs using the demultiplexer. This requires in each case the evaluation of the Program Association Table and Program Map Table, and also that the PIDs of the elementary streams to be reproduced be known to the demultiplexer in the set-top box. If the set-top box has a digital interface via which parts of the transport data stream can be stored and reproduced later or via which an arbitrary transport data stream can be fed to the set-top box, the demultiplexer must firstly be reprogrammed with the PIDs. Reproduction simply by the pressing of a reproduction (play) button is possible according to the invention, however, by virtue of the fact that the PID for the packets of at least one of the data streams is set to a predetermined value in the set-top box, the packets with this predetermined value of the PID being selected for reproduction.
