For video applications such as video-on-demand, signaling is an important step for service initialization including service setup, authentication, and resource allocation. This paper describes the design and implementation of an experimental platform for delivery of real-time MPEG encoded video over LAN with DSM-CC signaling. The platform consists of a real-time MPEG encoder system as a server, a network node workstation, and a client with MPEG decoding capability. Specifically, we have implemented a client- initiated subset of the DSM-CC user-to-network (UN) protocol for signaling. Communication between the network node and server/client is achieved by using the TCP/IP protocol. The network node provides the functionality of upstream message exchange, UN and/or UU (user-to-user) resource negotiation, and MPEG bitstream relay. The operation of our current video platform setup is quite robust and can deliver MPEG video up to about 1.5 Mb/s via DSM-CC protocols. It is demonstrated that practical implementation of video applications is feasible over small-scale LANs.
