ABSTRACT:
A method and apparatus for decoding of two part binary symbols, such as JPEG symbols, is disclosed. The invention takes advantage of the relationship between the Huffman symbol length, the magnitude length, and the overall symbol length so that none of these lengths need to be stored in memory. Using the invention, a Huffman symbol can be detected. Once the symbol is detected, the invention facilitates the determination of the Huffman symbol length, the magnitude length, and the overall symbol length.
