发明名称 GENERATION OF VALID PROGRAM CLOCK REFERENCE TIME STAMPS FOR DUPLICATE TRANSPORT STREAM PACKETS
摘要 The present invention is suitable for use in a communications system that transmits a transport stream, such as an MPEG stream. The present invention addresses the need of generating a valid value for a duplicated packet in the transport stream. A first embodiment of the present invention interpolates between a PCR value in the original packet and the PCR value in the next PCR packet. A second embodiment of the present invention copies an original packet along with its PCR value into a duplicate packet. Subsequently, the present invention interpolates a new value for the original packet based on the original value in the duplicated PCR-bearing packet and the previous value in a PCR-bearing packet.
