摘要： The present invention provides a broadcast receiving terminal which improves power conservation, in which a user does not miss broadcast contents s/he likes. The broadcast receiving terminal (100) includes: a display unit (120) for displaying TV program content; a state administration unit (112) which judges whether or not to display the TV program content, based on the user's operation; and a first processing unit (110), which receives a digital broadcast wave and operates as follows: executes decoding on stream information, and causes the TV program content to be displayed in the display unit (120) when the TV program content are judged to be displayed. The first processing unit (110) presents an outline indicating real-time TV program information so that the outline is synchronized with the TV program content when the TV program content are judged not to be displayed.

摘要： A terminal determines a target value of stream data to be stored in its buffer in relation to its buffer capacity and the transmission capacity of the network. Also, the terminal arbitrarily determines a delay time from when the terminal writes a head data of the stream data to the buffer to when the terminal reads the data to start playback in a range not exceeding a value obtained by dividing the buffer capacity by the transmission capacity. The target value and the delay time are then both notified to a server. Based on those notified values, the server controls the transmission speed so that the buffer occupancy of the terminal changes in the vicinity of the target value without exceeding the target value.
摘要翻译：终端根据其缓冲器容量和网络的传输容量确定要存储在其缓冲器中的流数据的目标值。此外，终端任意地确定从终端将流数据的头数据写入缓冲器的延迟时间到当终端在不超过通过将缓冲容量除以传输而获得的值的范围读取数据开始重放时的延迟时间容量。然后将目标值和延迟时间通知给服务器。基于这些通知值，服务器控制传输速度，使得终端的缓冲器占用在目标值附近改变而不超过目标值。
