With the development of people's living standard, more and more viewers desire HD program for its special feeling. It is a leap in the process of audio-visual effect and a development trend of future TV program.The New Visual HD Channels of SMG SITV has broadcast 15 hours every day since Jan 1st, 2006. But there is some hidden trouble in original broadcast pattern. For example, when tapes repeat playing, picture quality gets worse and worse, or there is little secure backup. High quality, continuity, economic and safety is the rule of broadcast. So, high picture quality and stable system are necessarily required.For the purpose, we tried to design a fully-automatic HD Media Server broadcast system. In the process, I was in charge of designing hardware system. I combined the facts of the broadcast center and put forward a possible proposal .We matured the plan by constant revision. Now, the new system runs steadily and shows many merits. It improves efficiency, raises broadcast security, and eases labors.
