Decode control apparatus, decode control method, computer program, and recording medium

摘要

A decode control apparatus (1) of decoding encoded data and generating reverse playback image data, includes a unit for controlling (5) the reading of the encoded data at a specified playback speed, a unit for generating, from the encoded data read under the control of the read control unit, an encoded data group composed of a first encoded data unit to be displayed in reverse playback and a second encoded data unit required to decode the first encoded data unit, a unit for distributing (7) the encoded data group among a plurality of decoders (10) decoding in accordance with the specified playback speed, and a unit for generating the reverse playback image data (8) responsive to the specified playback speed, based on the first encoded data unit, contained in a data group decoded from the encoded data group by the decoders.
