<P>PROBLEM TO BE SOLVED: To shorten a period of time until displaying a video in channel switching without loading an excessive load onto a server in a content distribution system for distributing a video content. <P>SOLUTION: Each of viewing devices 1-1 to 1-n receives a packet from a program distribution server 3, reproduces the content and stores the received packet in a storage unit 11. The viewing device 2-1 transmits a channel switching request (a), that designates a channel of the switching destination in channel switching to a channel switching control server 4. The channel switching control server 4 selects the viewing device 1-n, that stores the packet of the channel designated by the request (a), from among the viewing devices 1-1 to 1-n, and transmits a transfer request (b). The viewing device 1-(n), that receives the request (b), transfers a packet for compensation, containing a latest intra-frame, stored in the storage unit 11 to the viewing device 2-1. The viewing device 2-1 reproduces the content by using packets from the viewing device 1-n and the program distribution server 3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
