Abstract:
1. A system for streaming packets of multimedia data between a server and reception apparatus comprising: a communication network for providing a transmission access path through which the server can stream multimedia data to the reception apparatus and a transmission access path through which the reception apparatus can access the server, where said server transmits the packets of multimedia data to the reception apparatus and said reception apparatus records a time stamp of the received time for each packet of multimedia data from the server and transmits the recorded time stamp to the server, a control unit for controlling the time stamps of the received packets of multimedia data so that the recorded time stamps are transmitted from the receiving apparatus to the server in a predetermined cycle, a bandwidth calculation unit responsive to said control unit for calculating a transmission bandwidth from transmitted packets of multimedia data by dividing the packet size of one transmitted packet by a time interval based on the recordal of time stamps of successive packets and calculating a final transmission bandwidth based upon determining a median from a selected number of transmission bandwidths within said predetermined cycle, with the multimedia data to be streamed to the reception apparatus based on the final calculated transmission bandwidth.
