介绍一种基于M642的视频无线传输系统,在此基础上重点探讨了关于TS流传输的问题,提出了使用McBSP和GPIO方式分别实现TS流传输,并给出了一种改进的乒乓方式。实验结果证明,采用McBSP和GPIO都可以解决TS流传输问题,但在速度和实现难度方面采用GPIO表现更好,改进型的乒乓结构也在一定程度上提高了程序的效率。

In this paper, a wireless video transmission system based on DM642 is described. On the basis of this system, focus is put on the issue of TS stream. It is proposed that McBSP and GPIO means to achieve the TS stream are used separately, and that an improved ping-pong method is given. Results show that both GPIO and McBSP can solve the problem of TS stream transmission, but the GPIO pattern does better at the speed and realization difficulty. The ping-pong structure improves the efficiency of the program to some extent.
