| Abstract: | In this paper,the principle and flow of traditional channel-turning mechanism are introduced.The drawbacks of the traditional mechanism are pointed out as well.And then,according to the practical issues and based on the task scheduling and message mechanism,the separating idea of data flow and control flow is adopted,and the optimal channel-turning mechanism of DVB-C digital Set Top Box(STB) is designed and implemented.Finally,the feasibility and advancement of this design are proved by experimental results... |
