Design and Implement of Multichannel Video Coding Terminal Based on DSP
基于DSP多通道视频编码终端的设计

The paper proposed a scheme of hardware design of a four-channel realtime video coder.The design of core chips of TMS320DM642 and audio/video chips were focused on.In addition storage,Ethernet,IIC and power source modules were discussed.Finally signal simulation was discussed and some keys of PCB layout and route were proposed.The software test proved the hardware worked well and produced good visual quality of audio/video.
