<p><P>PROBLEM TO BE SOLVED: To more suitably acquire packet data and to reproduce data. <P>SOLUTION: When a lost packet is judged to exist in a step S23, a data reproduction part of a client supplies the acquired packet and information to a packet restoration part. The packet restoration part performs a packet restorability judging processing in a step S24. A CPU judges in a step S25 whether restoration is possible or not based on the judged result in the step S24. When restoration is possible, the packet restoration part performs a data packet restoration processing and restores lost data packet in a step S26. When the restoration is impossible, the CPU requests retransmission of the lost packet from a server through a communication part. The invention can be applied to a streaming data distribution system. <P>COPYRIGHT: (C)2004,JPO</p> |
