Method of inserting data of a second type into an input stream of a first type

摘要

The invention proposes a method of generating, from an input transport stream of a first type and from data of a second type, an output transport stream of said first type which notably carries said data of said second type. This method consists of: generating an intermediate transport stream by creating available bandwidth in the input transport stream, inserting the data of the second type into the available bandwidth of the intermediate transport stream, thereby generating the output transport stream. The method notably applies to the generation of an MPEG-2 output transport stream from an MPEG-2 input transport stream and from MPEG-4 data. In this case an additional updating step is necessary to update PSI tables.
