Abstract

This paper presents an advanced video system which is based on the Alcatel HDTV codec 1741 VC. Broadcast of video signals in a point to multipoint network is upgraded by an interactive control and information interchange between the HDTV terminal side and the HDTV source. ATM cells are used to send the information through the network, advancing future and gaining access to next switching technology. Interface adaptation of HDTV codec to ATM network at 155 Mbit/s is accomplished in such a way that a bidirectional link is supported over the point to multipoint network. Main advantages of this novel system are the sharing of the HDTV coder by multiple decoders and the interactivity added to the terminal end. These features enhance network attractiveness in terms of cost and performance and, finally, gives an extra service of multiple applications.
