Abstract: A terminal determines a target value S_target 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 T_delay 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. Those 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 Sum of the terminal changes in the vicinity of the target value without exceeding the target value.

Abstract: A protocol-conforming server system separated into the receive part and the send part and provided with a receive protocol processor for processing the receive and a send protocol processor for processing the send which permits speedy sending out large-sized data which requires to be continuous and consecutive, e.g., moving image data and audio data. Packet header models are provided as template to save processing time, for the data covered by the present invention are sent out in the form of a packet, and almost the same packet header is used each time.

Abstract: A bus bridge apparatus that connects two system buses independent of each other to which a bus arbiter operating independently and located outside of the apparatus, has a function for serving as a master and a slave of the system buses, a base address holding means, and a bus address generating means.
