摘要： PROBLEM TO BE SOLVED: To realize optimal distribution control of a video stream in accordance with processing capacity of a video distributing server and a client. SOLUTION: When a distribution request is received from a client, processing loads at a point of time when the distribution request is received are obtained for every client connected for distributing the video stream, the total values are estimated as the present processing loads (S603), and processing loads on distribution of the video stream according to the distribution request to the client are estimated (S604). Then, on the basis of either the estimated present processing loads or the processing loads on distribution of the video stream according to the distribution request to the client, distribution control of the video stream is performed (S606 to S609).

摘要： PROBLEM TO BE SOLVED: To reduce a load when a user changes a broadcasting receiving device using a conditional access system.
SOLUTION: The broadcasting receives device which receives contents encoded by a first code key updated for each fixed-length playback section, and the first code key encoded by a second code key updated for each fixed-length playback section, from a transmitting device. The broadcasting receiving device includes: a means for inquiring the other receiving device about whether or not the other receiving device holds the right to playback the contents to be reproduced; a means for requesting the transmitting device to transmit the second code key encoded by a third code key unique to the receiving device in place of the third code key unique to the other receiving device when the other receiving device holds the right; and a means for decoding the received second code key by the third code key, decoding the first code key by the decoded second code key, and decoding the contents by the decoded first code key for playback.

摘要： A plurality of moving picture transmitters (11 to 1n) encode a plurality of input objects, respectively, and transmit them onto a network (41). A moving picture receiver (21) receives bitstream data transmitted from each of the plurality of moving picture transmitters (11 to 1n), obtains information on the quality of the network (41), detects an error or the like that occurs in the bitstream data, and transmits priority information on the plurality of objects to the plurality of moving picture transmitters (11 to 1n), respectively. A registration server 31 registers information on the plurality of moving picture transmitters (11 to 1n) and information on the moving picture receiver 21 therein, and delivers them according to circumstances.
