Abstract

Recently, media convergence and interoperability over multiple networks is becoming a determining factor for the success of new digital broadcasting and telecommunication services. In this presentation, we propose an original architecture framework providing a mean for seamless transport of RTP baesd streaming over both Internet and ISDB (ARIB) networks. This goal is achieved by using the independence of the RTP protocol from the transport layer, and by remarking that MPEG-2 based systems such as ISDB provide a high-quality packet delivery scheme with the DSM-CC protocol. We propose to carry RTP/RTCP packets in DSM-CC messages, whereas an RTSP messages subset is being mapped onto ARIB DSM-CC event messages.
