    摘要: The present invention is to provide a variable length decoding method for decoding complete binary tree code, which is implemented to an entropy coding module for executing the process comprising the steps of: procuring a TabIndex to calculate a value T=└log2(TabIndex)┘; reading T bits from a bitstream to obtain a first result M; determining whether or not the result M is smaller than (TabIndex−(1

    摘要: A method for concatenating MPEG-4 or H.263 segments is provided. The method includes extracting and comparing the VOL or picture header information of each segment. If the two segments have the same VOL or picture header information, the method merges the two segments directly by appending one segment to another to form a new bit stream. If the two segments have the different resolution, the method completely decodes and re-encodes the segments and then merges the segments. Otherwise the method takes the VOL or picture header information of one segment as reference to produce the new bit stream. The method parses the other segment frame at a time, re-encapsulates it according to the reference VOL or picture header information, and appends it to the one segment. During the process, the method only uses VLD to parse the other segment without using the tools of DCT, IDCT, ME, and MC.
