Video bit stream decoding system and method used in a video decoding apparatus
The present invention provides a video bit stream decoding system for decoding a video bit stream. The video bit stream includes at least one video packet. The video packet includes a packet header and a plurality of logical units. Each logical unit includes at least a first set of encoded parameters. The first set of encoded parameters can be decoded together with other corresponding sets of encoded parameters included in other logical units for generating a corresponding video macroblock. The video bit stream decoding system includes a searching module and a decoder. The searching module is used to search a corresponding starting decoding position from the logical units. The decoder is used to decode the encoded parameters of the logical units according to the corresponding starting decoding positions for generating a plurality of pixel data. The video macroblock is composed of the plurality of pixel data.
