ITU-T 656 question

    Hello,

    I have a question regarding digital encoding of an analog video
    signal.

    Assume you are having a video ADC that is outputting a 656 stream. If
    the analog signal is slightly "faster" than it should be, say the line
    period is shorter than 64us, what will a normal video ADC do?
    Will it pad the blanking interval with zeroes, when it detected a
    hsync slightly earlier than it expected?
