    What is this pattern ? Is it generated with a signal generator ? Is It white noise ? If the input signal pixel values have the BT656 synch codes it will cause problems with the VIP parser as it will detect wrong frame boundaries and frame rate will be wrong.Frame width is showing up wrong.

    What is this pattern ?

    - it's white noise

    Is it generated with a signal generator ?

    - no, it's from some TV tuner

    If the input signal pixel values have the BT656 synch codes it will cause problems with the VIP parser as it will detect wrong frame boundaries and frame rate will be wrong.Frame width is showing up wrong.

    - did you mean it's illegal signal? how do I test that or prove that?

    After I connect the output of the TV tuner to Sony's TV, we found there's nothing like white noise shown on TV but the original blue frame with dithering.

    So we think it should be the problem of source. Thanks.
