Abstract
A TTS preparation processing section attaches a time stamp to each of packets in an MPEG-2 TS (Transport Stream) to convert the MPEG-2 TS into an MPEG-2 TTS (Time-stamped Transport Stream). A grouping section collects a predetermined number of packets in the MPEG-2 TTS to form a group. A null packet removal section removes null packets from the group. A transmitting section shifts the MPEG-2 TTS packets in the group, from which the null packet has been removed, frontward to convert the MPEG-2 TTS packets into an RTP (Real-time Transport Protocol) packet and transmits the RTP packet to a communication line.
