A method for automatically advancing an audio/video signal past undesirable material comprising the steps of (A) detecting possible triggering events during encoding of said audio/video signal, (B) generating one or more scores of various levels in response to said triggering events and (C) advancing past said undesirable material during playback in response to one of said scores.

A method for securing a content is disclosed. The method generally includes the steps of (A) generating a media key by decrypting a media key block based on a device key unique to a particular player of a plurality of players, (B) modifying the media key by decryption based on a class key such that the media key is unique for each of a plurality of subscriber classes, (C) writing an encrypted title key in a media by encrypting a title key based on both the media key after modification and a medi...

An apparatus including a first circuit, a second circuit and a third circuit. The first circuit may be configured to generate a plurality of first motion vectors and first error scores in response to a search of a macroblock of an image. The search generally includes a range of motion vectors of the macroblock. The second circuit may be configured to generate a plurality of second motion vectors and second error scores for a plurality of sub-blocks of the macroblock in response to a set of discr...

A method for encoding video, comprising the steps of (A) detecting repeated fields in a video sequence and (B) generating a first repeated frame from a top field and any adjacent bottom field based upon detection of the repeated fields, wherein the top field and the bottom field are from one film frame.

A method for deinterlacing a picture is disclosed. The method generally includes the steps of (A) generating a plurality of primary scores by searching along a plurality of primary angles for an edge in the picture proximate a location interlaced with a field of the picture, (B) generating a plurality of neighbor scores by searching for the edge along a plurality of neighbor angles proximate a particular angle of the primary angles corresponding to a particular score of the primary scores having...

A method for deinterlacing a picture is disclosed. The method generally includes the steps of (A) determining a protection condition by performing a static check on the picture in a region around a location interlaced with a first field of the picture, (B) calculating an interpolated sample at the location by temporal averaging the first field with a second field in response to the protection condition indicating significant vertical activity and (C) calculating the interpolated sample at the lo...
