System for transmitting stream data from server to client based on buffer and transmission capacities and delay time of the client
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（中）：

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。
