ABSTRACT:
A method and apparatus for decoding variable length encoded signals is described. A decoder receives an encoded bitstream. The decoder retrieves N bits from the bitstream. The decoder retrieves a first value from a first table using the N bits. The decoder retrieves a second value from a second table using the first value, and determines whether the second value is a valid code. If the second value is a valid code, the decoder parses the second value to retrieve a run value, an amp value and a code length value.
