Abstract:
Method for decoding a stored packetized data stream for reproduction in a trick play mode, said packetized data stream being stored in accordance with a predetermined format understandable by the decoder, said stored packetized data stream comprising objects each comprising packets, a packet comprising a header and a payload, an elementary stream being encapsulated as payload in the packets, said method comprising the steps of:selecting objects, according to their headers, contiguous or not, in the elementary stream, in order to play trick modes. extracting the packets of the selected objects from the stored packetized data stream, inserting a packetized data stream packet header before said object header, in order to obtain a reconstructed data stream in accordance with said predetermined format; transferring said reconstructed stream to a packetized data stream parser.
