摘要： In a communication system using a terminal connected to a packet network, the invention predicts a future communication state between terminals. This invention may also control congestion by delivering the packet according to the predicted future communication state. A receiving state monitor calculates a moving average of jitter and a packet loss rate based on a packet received by a packet receiver. A controller of a sending bit rate and an encoding rate obtains the moving average of jitter and the packet loss rate predicts a future communication state, and controls the sending bit rate and/or the encoding rate.

摘要： When carrying out reception and video-recording of a plurality of programs, a stream receiving unit (201) of a receiver (200) receives one of the plurality of programs, a recording unit (203) outputs a recording start request and a recording end request to a recording control unit (103) of a video-recording and distribution apparatus (102), a recording control unit (103) records a predetermined program according to the recording start request and the recording end request, and a download receiving unit (205) of the receiver (200) outputs a download start request after the stream receiving unit (201) ends the reception of the one of the plurality of programs to download recorded data of another one of the plurality of programs which are recorded by the video-recording and distribution apparatus (102). The receiver (200) thus limits the number of programs which it receives simultaneously to one.
