Abstract:
1. A decoding apparatus comprising: table storage means for storing, in correspondence with M types of variable-length code tables, M tables holding minimum code words or maximum code words of N classes of variable-length code words constructing a variable-length code table; table selection means for selecting a table from the M tables in said table storage means; N comparison means for comparing input coded data with the minimum code words or maximum code words outputted from the table selected by said table selection means; class discrimination means for obtaining a class number corresponding to an initial code word of the input coded data based on results of comparison by said N comparison means; code length conversion means for converting the class number obtained by said class discrimination means into a code length; and address generation means for generating an address to access a memory holding decoded data from the class number and the code length outputted from said code length conversion means.
