1. method that is used to test the function of STB terminal (STT), described method comprises:

  • Fetch resolution chart from memory device, described resolution chart is configured to be convenient to test at least one parts of described STT;

    The resolution chart fetched of decoding digitally;

    To be kept in first frame buffer through the resolution chart of decoding;

    To convert simulation test figure to through the resolution chart of decoding;

    To be modulated into radiofrequency signal through the resolution chart of conversion;

    The modulated resolution chart of decaying;

    In response to the resolution chart that receives through decay, with described STT be tuned to required channel;

    To be transformed into numeric field through the resolution chart of decay;

    Digitally decode through the resolution chart of conversion;

    To be kept in second frame buffer through the resolution chart of decoding;

    AndConvert described resolution chart to analog signal through decoding.
