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.
