摘要： A method and system of transform-based encoding, decoding, and bitstream generation of digital video content. The digital video content comprises a stream of pictures, slices, or macroblocks which can each be intra, predicted or bi-predicted pictures. The pictures, slices, or macroblocks comprise blocks of pixels. The method comprises scanning frequency coefficients from each of the block's two dimensional array of frequency coefficients in a manner that is vertically biased.

摘要： In one embodiment, a method for encoding or decoding video content is provided. The method determines a plurality of sets of interpolation filters for use in interpolating sub-pel pixel values for a temporal prediction process of video content. Different sets of interpolation filters include different phase offset characteristics. A unit of video content is received. The method then selects one of the set of interpolation filters to interpolate a set of sub-pel pixel values for use in the temporal prediction process for the unit of video content based on characteristics associated with the encoding or decoding of the video content. The one of the set of interpolation filters is selected based on the phase offset characteristic of the one of the set of interpolation filters and the characteristics associated with the encoding or decoding.

摘要： A (50) method and apparatus (110) for determining a scanning format of a frame of a video signal determines (52) if any interfield motion exists within the frame; and indicates (53) that the frame is interlaced scanned if interfield motion is detected and indicates (54) that the frame is progressive scanned if interfield motion is not detected. The determination is based on spatial correlation within and around one or more edges of one or more objects in the frame. This can be accomplished by identifying zig-zag or zipper effects near one or more edges of one or more objects in the frame, identifying motion between fields or identifying motion near one or more edges of one or more objects. A method (100) for determining a field order of two interlaced frames of a video sequence of frames assigns (101) one of the two interlaced frames to be a first frame and the other of the two interlaced frames to be a second frame and assembles (102) two new frames from the two interlaced frames by combining a bottom field of the first frame with the top field of the second frame and by combining a top field of the first frame with a bottom field of the second frame. The number of zipper points in each of the two new frames is then determined and compared. If the number of zipper points in the first frame is smaller than the number of zipper points in the second frame, that the field order of the two frames is top field first, otherwise the field order is bottom field first.
