An innovative solution for achieving media convergence using RTP streaming in ARIB framework

Recently, media convergence and interoperability over multiple networks are becoming a determining factor for the success of new digital broadcasting and telecommunication services. In this paper, we present an original architecture framework providing a mean for seamless transport of RTP based 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 Systems based ISDB provides 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. The complete architecture is evaluated using a PC based simulator including a BML browser and a transport stream demultiplexer card.
