Abstract
A method, system, and computer program product for decoding a variable length code. A decoding module is configured to receive the variable length code. The variable length code is a plurality of bits. The decoding module is also configured to identify a number of times the lead bit is repeated consecutively at the beginning of the plurality of bits. The lead bit is predetermined to be one of a 1 or 0. The decoding module is also configured to identify a code word in a table of code words by using the number of times the lead bit is repeated.
