    • A method and apparatus are provided for video motion compensation suitable for use in decoding compressed video. An input buffer receives lines of blocks of video data and outputs lines of these to a first block transpose unit (52). This can selectively transpose the lines and columns of an input block of pixels. A vertical line filtering unit (58) is coupled to the block transpose unit for producing an output line of interpolated pixel samples. A first selector with inputs coupled to the output of the vertical line filtering unit and to the output of the input block transpose unit is able to select between an un-interpolated output line of pixels and an interpolated output line of pixel samples. A second selector (62) with inputs coupled to the outputs of the first block transpose unit and to the vertical line filtering unit is able to select between lines of pixels from the first input block transpose unit and from the vertical line filtering unit and provides these to a horizontal line filtering unit (66). The first and second selectors (60), (62) receive control signals related to motion vectors in an incoming stream of data.
    • 提供了适用于解码压缩视频的视频运动补偿的方法和装置。 输入缓冲器接收视频数据块的行并将其输出到第一块转置单元(52)。 这可以选择性地转置输入像素块的行和列。 垂直线滤波单元(58)耦合到块转置单元,用于产生插值像素采样的输出线。 具有耦合到垂直线滤波单元的输出和输入块转置单元的输出的输入的第一选择器能够在未内插的像素输出线和像素采样的内插输出线之间进行选择。 具有耦合到第一块转置单元和垂直线滤波单元的输出的输入的第二选择器(62)能够从第一输入块转置单元和垂直线滤波单元的像素行之间进行选择,并且提供这些 到水平线滤波单元(66)。 第一和第二选择器(60),(62)接收与输入的数据流中的运动矢量有关的控制信号。
