  Abstract

A growing diversity of pervasive devices is gaining access to the Internet and other information. However, much of the rich multimedia contents cannot be easily handled by the client devices because of the limited communication, processing, storage and display capabilities. The integration of voice, data and video services modified the target of networking technologies. Networks must have some the capabilities for integration of various services and also for QoS support as required by each of those services. Because of these reasons, we developed EAGIS(Efficient ATM Gateway for real time Internet Service) to provide seamliss multimedia service between the ATM network and the Internet. EAGIS consists of the interworking unit, content server, transcoding server, and the service broker to provide seamless multimedia service between the ATM network and the Internet. In this paper, we design the architecture and transcoding service scenario of the EAGIS. When the RTP is used for the bi-directional communication, transcoding time is configured by the time-stamp of RTCP. When HTTP is used for unidirectional communication, self-timer is used. By using these reference time, standard transcoding method is applicable according to the frame transmission rate and network traffic load. And we can also assure the QoS of the multiple users'' effective bandwidth by our algorithm.
