Variable length decoding method, storage medium, variable length decoding device |
摘要 |
<p>The present invention correctly decodes data encoded with a variable-length encoding method that improves the compression ratio. The variable-length encoding method encodes a unit data composed of a plurality of sub-data while referencing parameter tables, and includes the following steps:
an initialization step in which an obtained parameter table is set to initial values;
a parameter table information encoding step in which information related to the initialized parameter table is encoded;
a parameter obtainment step in which encoding parameters to be used in the encoding of sub-data are obtained from the parameter table;
a sub-data encoding step in which variable-length encoding of the sub-data is performed with reference to the obtained encoding parameters, and
an encoded information placement step in which the encoded information is placed in a position in which the information can be obtained before the encoded unit data.</p> |
