Patent ID: 7502513

Claim:
A method for classifying a first video type and a second video type in one video signal, comprising the steps of: (A) buffering said video signal in a buffer, said video signal carrying a content comprising a sequence of frames; (B) reading a first of said frames from said buffer directly to an analyzer; (C) reading a second of said frames from said buffer directly to said analyzer; (D) generating in said analyzer a plurality of first parameters defining a first transition portion between a first active portion and a first blank portion in said first frame; (E) generating in said analyzer a plurality of second parameters defining a second transition portion between a second active portion and a second blank portion in said second frame, wherein said second frame follows said first frame in said content by a fixed temporal distance; (F) comparing said first parameters with said second parameters to generate a comparison value; and (G) generating a signal indicating (i) said first video type when said comparison value is greater than a predetermined threshold and (ii) said second video type when said comparison value is less than said predetermined threshold, wherein said predetermined threshold determines if said first frame and said second frame are part of an unbroken segment in said content.
