    • 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.
    • 本发明涉及一种解码装置和相同的视频比特流解码方法。 该装置解码编码的视频比特流以产生第一和第二宏块的像素数据。 视频比特流包括至少一个视频分组,第一,第二,第三逻辑单元。 第一逻辑单元包括参数a1和b1。 第二逻辑单元包括参数a2和b2。 第三逻辑单元包括参数a3和b3。 参数a1和a2用于重构第一宏块。 参数b1和b2用于重构第二宏块。 视频解码装置包括搜索模块和解码模块。 搜索模块定位指示第一逻辑单元的位置的第一地址,指示第二逻辑单元的位置的第二地址以及指示第三逻辑单元的位置的第三地址。 解码模块首先对第一逻辑单元进行解码以获得与参数a1对应的解码参数A1,而不将与参数b1相对应的解码参数B1存储到存储器中。 解码模块还对第二/第三逻辑单元进行解码以获得对应于参数a2 / a3的解码参数A2 / A3。 然后,使用解码参数A1,A2和A3来产生第一宏块的像素数据。
