How to capture video frame by frame through S-video/RAC/HDMI/YPbPr port

[sunnyermao]

    We want to do auto test system for  Satellite TV terminal, the terminal with 4 kinds of output ports, respectively is S-Video Port, RAC port, HDMI port, YPbPr port. Previously, we do test by connecting all the output ports to TV set, and watch the video played on TV to judge the terminal is OK or not.

     Now, we want to do the test automatically: capture the analog signals from the output ports frame by frame, and compare them with the reference signals to see if DUT is OK or not. (Sample rate 30~40 frames/second, one video signals last less than 10s), all the 4 output ports should be tested.

    With your knowledge and experimence, Anyone who can recommend some hardware+software which can meet above requirement? (Labview is not compulsory)
