Patent ID: 8285113

Claim:
A method of a reproducing apparatus to guarantee seamless playback, the method comprising: reading, by the reproducing apparatus, a first data stream having packets having a first sequential arrival time stamps and a second data stream having packets having a second sequential arrival time stamps, and information on a time difference value between a last packet of the first data stream and a first packet of the second data stream, wherein an arrival time base of the first data stream is different from an arrival time base of the second data stream; and processing, by an arrival time stamp processor in the reproducing apparatus, packets using the arrival time stamps of the packets, wherein a counter in the arrival time stamp processor is reset to an arrival time stamp included in the first packet of the second data stream using the information on time difference value between a last packet of the first data stream and a first packet of the second data stream in order to process seamless playback of the first data stream and the second data stream.
