Abstract: A method of video processing by a video processor includes receiving a first syntax element in a coded video bitstream. The first syntax element can be a high level syntax element and indicate whether a height of each of a plurality of pictures in a video sequence of the coded video bitstream is equal to or larger than a width of the respective picture in the video sequence of the coded video bitstream. The pictures in the video sequence of the coded video can be processed in an orientation that is determined according to the first syntax element indicating whether the height of each of the plurality of pictures in the video sequence of the coded video is guaranteed to be equal to or larger than the width of the respective picture in the video sequence.

Abstract: A method for implementing motion estimation comprising the steps of (A) performing a motion estimation search on one or more blocks of sub-sampled images to generate a first plurality of motion vector scores, (B) applying a first adjustable bias to any one or more of said first plurality of motion vector scores with a lowest sum of absolute differences score, (C) selecting a motion vector with a lowest adjusted score in response to applying the first adjustable bias, (D) performing a motion estimation search on one or more blocks of non-sub-sampled images to generate a second plurality of motion vector scores with the selected motion vector with the lowest adjusted score, (E) applying a second adjustable bias to any one or more of the second plurality of motion vector scores with the lowest sum of absolute differences score and (F) selecting a final motion vector for each target block position.

Abstract: A method for motion estimating. The method generally includes the steps of (A) generating a first interpolated block having a sub-pixel resolution in response to a first interpolation process operating on a reference block of a reference frame of a video signal having an integer pixel resolution, (B) generating a motion vector in response to the first interpolated block and a current block of a current frame of the video signal having the integer pixel resolution and (C) generating a second interpolated block having the sub-pixel resolution in response to a second interpolation process operating on the reference block.

Abstract: An encoding method for reducing motion video data sizes using a multitude of variable-sized data blocks that are derived from spatial translation vectors and the motion field of an image. Using variable-block sizes to characterize the groups of picture elements (pixels) in an image frame allows for the inter-mixing of coarse (for static areas) and fine (for areas of complex motion) resolution data descriptions in the same descriptive data block. A comparison of motion event areas is made between successive video frames, and a motion displacement vector is calculated for each pixel location in the frame. A data tree is constructed from these pixel motion vectors and is pruned to eliminate static areas. The remaining leaves of the pruned tree are encoded differentially and applied to a lossless arithmetic encoder to provide a significantly reduced data block that still retains the highest resolution of the image.
