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 t he transport stream. A first embodiment of the present invention interpolate s between a PCR value in the original packet and the PCR value in the next P CR packet. A second embodiment of the present invention copies an original p acket along with its PCR value into a duplicate packet. Subsequently, the pr esent invention interpolates a new value for the original packet based on th e original value in the duplicated PCR-bearing packet and the previous value in a PCR-bearing packet.
