Abstract:
Task: To provide communication technology in which clock synchronization accuracy can be easily maintained, even on networks where packets can be easily lost.Resolution Means: A communication device, comprising: a transmission unit that includes a flag processing unit that, upon receipt of one or a plurality of MPEG-2 TS packets, applies flag information to the packets at a predetermined interval in the forward reproduction direction of the packets, and a time stamp application unit that generates MPEG-2 TTS packets by applying a time stamp value calculated using a GPS clock to each of the one or a plurality of MPEG-2 TS packets, including the MPEG-2 TS packets having the flag information applied by the flag processing unit, and transmits the MPEG-2 TTS packets to a transmission path.
