Abstract: The invention relates to a decoding apparatus and same method for decoding a video bit stream. The apparatus decodes an encoded video bit stream to produce pixel data of a first and second macroblocks. The video bit stream comprises at least one video packet, a first, second, third logic units. The first logic unit comprising parameters a1 and b1. The second logic unit comprises parameters a2 and b2. The third logic unit comprises parameters a3 and b3. The parameters a1 and a2 are used for reconstructing a first macroblock. The parameters b1 and b2 are used for reconstructing a second macroblock. The video decoding apparatus comprises a searching module and a decoding module. The searching module locates a first address indicating location of the first logic unit, a second address indicating location of the second logic unit, and a third address indicating location of the third logic unit. The decoding module first decodes the first logic unit to obtain a decoded parameter A1 corresponding to the parameter a1 without obtaining and storing a decoded parameter B1 corresponding to the parameter b1 into a memory. The decoding module also decodes the second/third logic unit to obtain a decoded parameter A2/A3 corresponding to the parameter a2/a3. Then, the decoded parameters A1, A2, and A3 are used to produce the pixel data of the first macroblock.

Abstract: An interpolation unit receives an incoming video bit stream comprising a plurality of frames including first macroblocks encoded using block-matching motion compensation and second macroblocks encoded using global motion compensation. A translation unit converts global motion parameters included in a current frame of the incoming video bit stream into a global motion vector. The interpolation unit performs luminance and chrominance interpolation operations on each macroblock contained in each frame of the incoming video bit stream. When processing a current macroblock, if the current macroblock is encoded using global motion compensation, the interpolation unit performs the luminance interpolation operations according to the global motion vector at half-pel resolution, and performs the chrominance interpolation operations at quarter-pel resolution. If the current macroblock is encoded using block-matching motion compensation, the interpolation unit performs the luminance and chrominance interpolation operations according to the macroblock motion vector contained in the current macroblock at half-pel resolution.
