A method for classifying a first video type and a second video type in a digital video signal having a series of frames is disclosed. The method generally includes a first step of (A) reading a first set of parameters defining an active portion of a first of the frames. A second step may involve (B) reading a second set of parameters defining an active portion of a second of the frames. A third step includes (C) comparing the first set of the parameters with the second set of parameters to generate a comparison value. As such, (D) if the comparison value is above a predetermined threshold, indicating the first video type and (E) if the comparison value is not above the predetermined value, indicating the second video type.
