1. A method of detecting a scene change in a digital video sequence having a plurality of frames, the method comprising:

  • calculating a first root mean squared (RMS) value for a first frame relative to a second frame and the second frame relative to a third frame;

    calculating a first mean absolute difference (MAD) value for the first frame relative to the second frame;

    determining if the first RMS value meets a first criterion;

    determining if the first MAD value meets a second criterion; and

    designating the second frame as a scene change frame at least partly in response to determining that both the first RMS value meets the first criterion and the first MAD value meets the second criterion.
