Abstract :
In this paper, a video wireless transmission system based on DVB-T is introduced with the DM642. Based on this system, the packing-unpacking TS stream device is designed in DSP, and the method to output TS stream by means of using EDMA, GPIO and serial peripheral interface (SPI) is proposed. This method which has been proved is an effective solution to transport TS streams. It is not only reduces the cost but also reaches the industrial temperature level standards.
