Abstract: A communication system includes: communication terminals; and a server that can connect to and communicate with the communication terminals, wherein: the server including: a first communication section that communicates with the communication terminals; a storage section that stores a plurality of connection patterns each of which indicates timings at which the communication terminal will access the server; a pattern selection section that selects one of the connection patterns from the storage section; and a first control section that controls the first communication section to transmit the connection pattern selected by the pattern selection section to the communication terminal the first communication section connects to; and the communication terminal including: a second communication section that communicates with the server; and a second control section that controls the second communication section to connect to the server at timing indicated in the connection pattern received by the second communicati

Abstract: The present invention is intended to realize high-speed and stable communication. A multi-flow RTP divides the data of one RTP session into pieces that can be transmitted through UDP ports through respectively and supplies the divided pieces of data to these ports. An RTCP controls the UDP ports through to transmit the divided data and controls a TCP port to transmit control information for reconstructing the divided data. UDP ports through receive the divided data and supplies the received data to a multi-flow RTP. An RTCP obtains the control information from the TCP port and supplies it to the multi-flow RTP. The multi-flow RTP reconstructs the divided data according to the control information and supplies the reconstructed data to the player, which reproduces the reconstructed data. The present invention is applicable to a stream data distribution system, for example.
