Abstract
An apparatus includes a compact table generator module and a storage medium. The compact table generator creates a compact code table having multiple code word groups arranged in one or more hierarchies. Each of these code word groups includes a group mask that corresponds to one or more code words in a variable length code table. The storage medium stores information regarding the code word groups, such as a group mask for each of the code word groups, and a code index for each code word in the variable length code table.
