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

A decode control method for decoding encoded data and generating reverse playback image data, the method comprising steps of:

• controlling the reading of the encoded data at a specified playback speed;
• generating, from the encoded data read under the control of the read control step, 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;
• distributing the encoded data group among a plurality of decoders decoding in accordance with the specified playback speed;
• and
• generating the reverse playback image data 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.

A computer program for causing a computer to decode encoded data and generate reverse playback image data, the computer program comprising steps of:

• controlling the reading of the encoded data at a specified playback speed;
• generating, from the encoded data read under the control of the read control step, 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;
• distributing the encoded data group among a plurality of decoders decoding in accordance with the specified playback speed;
• and
• generating the reverse playback image data 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.

A recording medium recording a computer program for causing a computer to decode encoded data and generate reverse playback image data, the computer program comprising steps of:

• controlling the reading of the encoded data at a specified playback speed;
• generating, from the encoded data read under the control of the read control step, 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;
• distributing the encoded data group among a plurality of decoders decoding in accordance with the specified playback speed;
• and
• generating the reverse playback image data 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.

A decode control apparatus for decoding encoded data and generating reverse playback image data, the apparatus comprising:

• a controller controlling the reading of the encoded data at a specified playback speed;
• a generator generating, from the encoded data read under the control of the read controller, 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 distributor distributing the encoded data group among a plurality of decoders decoding in accordance with the specified playback speed;
• and
• a generator generating the reverse playback image data 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.
