The design of multi-channel video network transmission Embedded System based on DM642

Based on TI's digital media processor chip TMS320DM642, This work designs and achieves multi-channel video acquisition, finished the transportation of Ethernet of video information. It uses the video interface of integrated of TMS320DM642, Ethernet interface modules EMAC/MDIO, Phillips's SAA7113 video decoder chip and adaptive Ethernet transceiver chip Intel LXT971A, to complete the design of video acquisition interface and network transmission system. In the end, with the help of embedded operating system DSP/BIOS, It completes the system software design.
