| Abstract: | The interactive multi-media CATV network is the tendency of the development .The implementations perspect of the CATV network of are very optimistic when their allocation and exchangeability are conbined. A video on telephone deplexer demand CATV system is propoesed and the digital rtansmission technologh of down-signal is intro-duced in this paper. Finally, the design of MPEG, test and down-instruction multi-pleser and demultiplexer are given. |
