Abstract
A bitstream conversion apparatus for converting a bitstream of a first format, containing content data, into a bitstream of a second format includes: a splitting unit which splits the bitstream of the first format in time sequential fashion into a plurality of split bitstreams of the first format; a plurality of conversion units which convert the plurality of split bitstreams of the first format into a plurality of split bitstreams of the second format; and a connecting unit which connects the plurality of split bitstreams of the second format to one another.

A bitstream conversion method for converting a bitstream of a first format, containing content data, into a bitstream of a second format, comprising:
- splitting the bitstream of the first format in time sequential fashion into a plurality of split bitstreams of the first format so as to provide an overlapping portion at each splitting position;
- converting the plurality of split bitstreams of the first format in a parallel fashion into a plurality of split bitstreams of the second format;
- and
- connecting the plurality of split bitstreams of the second format to one another,
- wherein the bitstream of the first format contains a moving image stream and an audio stream, and
- wherein the overlapping portion at each splitting position of the audio stream is made to have a longer time length than the overlapping portion at each splitting position of the moving image stream has.
A bitstream conversion apparatus for converting a bitstream of a first format, containing content data, into a bitstream of a second format, comprising:
- a splitting unit which splits the bitstream of the first format in time sequential fashion into a plurality of split bitstreams of the first format;
- a plurality of conversion units which convert the plurality of split bitstreams of the first format into a plurality of split bitstreams of the second format;
- and
- a connecting unit which connects the plurality of split bitstreams of the second format to one another,
- wherein the splitting unit splits the bitstream of the first format so as to provide an overlapping portion at each splitting position;
- wherein the bitstream of the first format contains a moving image stream and an audio stream, and
- wherein the splitting unit sets the overlapping portion at each splitting position of the audio stream so as to have a longer time length than the overlapping portion at each splitting position of the moving image stream has.
A non-transitory computer-readable storage medium storing a bitstream splitting program which, when executed by a computer for bitstream splitting process, causes the computer for bitstream splitting process to execute a process comprising:
- splitting a bitstream of a first format, containing content data, in time sequential fashion into a plurality of split bitstreams of the first format which are to be converted into a plurality of split bitstreams of the second format in a parallel fashion by a plurality of conversion units, so as to provide an overlapping portion at each splitting position,
- wherein the bitstream of the first format contains a moving image stream and an audio stream, and the overlapping portion at each splitting position of the audio stream is made to have a longer time length than the overlapping portion at each splitting position of the moving image stream has.
