STREAMING METHOD AND SYSTEM FOR EXECUTING THE SAME METHOD

PROBLEM TO BE SOLVED: To provide a streaming method, capable of preventing failure of streaming reproduction, even if the buffer capacities of terminals are different according to the kinds of devices, and even if the transmitting capabilities of a network fluctuate, and to make both prevention of the failure of the streaming reproduction and shortening of waiting time compatible at program searching. SOLUTION: A terminal decides a target quantity (S-target) of a stream to be stored in own buffer concerning the capacity of own buffer and the transmitting capabilities of a network; and it decides a delay time (T-delay), and writes the leading data of the stream in own buffer, until the data are read and started to be reproduced arbitrarily within a range, which is not beyond the value obtained by removing the buffer capacity by the transmitting capabilities, and notifies a server of the target quantity and the delay time. The server controls the transmission speed, so that the transition of the buffer occupancy quantity (Sum) of the terminal can be realized without exceeding the target quantity within the target quantity, based on the notification.
