Design and research on Video Monitoring System based on DM642
Jiang Chao-gen · Railway Computer Application · 2007
It was given a design of DM642 based on Video Monitoring System,its central processor was dedicated multimedia processor,TMS320DM642,this System could capture at most 4-route video signals at the same time,which brought down the cost effectively.And a new diamond search algorithm for fast-matching motion estimation in H.263 was proposeded to replace the traditional three-step search algorithm in the motion estimation region which could optimize the code after transplant from C/C++ to DSP.
