Abstract:
A mediate server for providing a real time video service between different networks having different network speeds, comprising:a service browsing means directly connected to a high speed network server for transferring a server address, service type, and selection is received from the user, receiving a result whether a mediate function is needed, and providing a service;a real time control means for transferring a result to the service browsing means when there is not a mediate function by judging whether the mediate function is needed by receiving a server address, service type, and selection list from the service browsing means, determining the buffer size after measuring a traffic based on the connection to the server when the mediate function is needed, allocating the buffer, requesting the data to the server, and receiving/transferring the data; anda stream control means for transferring to the user by using the stream protocol when receiving a minimum data from the real time control means;wherein said buffer size determination means is directed to determining the buffer size by the equation wherein the size of the buffer=the video file size*(the service request bandwidth-the traffic with the measured server)/the service request bandwidth.
