    Abstract: PROBLEM TO BE SOLVED: To improve processing in a decoder in a multimedia transmission system.
    SOLUTION: A fixed length code and a variable length code are parsed from a bit-wise stream of multimedia data by maintaining and reading the multimedia data in a processor-aligned way. A fixed length code word reads determined available bits and bits associated with a portion of the processor-aligned data, and a variable length code word reads at least some of the available bits. Variable length codes, particularly in a received state, are decoded using multiple levels of decoding tables to speed up decoder table lookup.
