Abstract
The present invention concerns a method and an apparatus for the synchronization and the scheduling of multiple data streams and real time tasks. In accordance with the present invention, pointers pointing to the information streams to be synchronized and processed are kept in the table (,) of a selector (,). The time marks (S1Start etc.) of said information streams are stored in a table (,) of a timer. The system time is checked against said time marks and if a time mark has been reached, the table (,) of said selector (,) is updated. If the status of an information stream is such that its trigger condition is fulfilled, the pointer to said information stream is made available at the output of the selector (,). This pointer is then used to retrieve the respective information stream and to forward it to a playout device.
