Patent ID: 6972801

Claim:
A digital video display device, comprising: a navigation unit operative to isolate an input video signal; a decoder operative to separate said input video signal into a plurality of frames, each frame containing a series of fields; a detection unit having means for generating a look-up table from substantially all of said plurality of frames prior to processing any one of said plurality of frames for display, said look-up table having entered therein one of a plurality of processing types associated with a corresponding one of said plurality of frames, said plurality of processing types including a null processing type corresponding to no predetermined processing type associated with said corresponding frame, said detection unit further having means for providing an indication of said processing type entry corresponding to said each frame from said look-up table; and a processing unit operative to execute a first processing algorithm corresponding to said indication of said processing type entry, said processing unit providing at an output thereof a filtered video frame corresponding to one of said plurality of frames for display on a progressive display device, wherein said first processing algorithm produces said filtered video frame from field data of said corresponding frame and a predetermined number of preceding frames.
