  • Method and apparatus for debinarization of digital video data during decoding
    Patent number: 7518536
    Abstract: A debinarizer and a hardware-based method for debinarizing a binary bit stream into symbols comprising predefined binary sequences are disclosed in which predefined binary sequences and their corresponding symbols are represented as tree structures. A binary sequence is debinarized by traversing one of the tree structures to determine a corresponding symbol. Similar tree structures may be combined to form a single tree structure. The tree structures may be implemented as a finite state machine.
