An Effective Method of Acquiring Video Data

  • Generally, in video data collection system based on FPGA,interfaces of FPGA and video data decoder need many I/O resource of FPGA.The paper introduced a new method of collection of video data, which locating and collecting video signal by checking SAV signal. The method only needed video data and pixel synchronization clock signal to realize acquisition of video data effectively, so saved limited I/O resources of FPGA and improved integration level of the system. Simulation result proved that this design method achieved the purpose of picking up video data in real-time.
