英文摘要：

The scheme of fast channel switching in mobile video service is proposed based on switching frames insertion. By increased the inserting switching fames properly, the main part of the channel switching time, time of waiting reference frames can be reduced. And then, the performance of the scheme is analysed and verified. The simulating results show that the scheme can effectively reduce the channel switching time of mobile video service.
