Abstract
In an information processing apparatus, an encoded data joiner joins divided and encoded data generated as a result of division-encoding target data that has been divided into a plurality of intervals at a predetermined number of division points. A decoder then decompresses the data generated by the encoded data joiner, and a re-encoder re-encodes the decoded data generated by the decoder. The re-encoder re-encodes the decoded data over just the minimum number of division point intervals containing data portions to be altered, thereby efficiently re-compressing data that has been altered.
Claims5
An information processing apparatus, comprising:
- an encoded data joiner configured to join divided and encoded data generated as a result of division-encoding target data that has been divided into a plurality of intervals at a predetermined number of division points;
- a decoder configured to decompress the data generated by the encoded data joiner;
- and
- a re-encoder configured to re-encode the decoded data generated by the decoder;
- wherein
- the re-encoder re-encodes the decoded data over the minimum number of division point intervals containing data portions to be altered.
An information processing method, comprising the steps of:
- joining divided and encoded data generated as a result of division-encoding target data that has been divided into a plurality of intervals at a predetermined number of division points;
- decoding the data generated in the encoded data joining step;
- and
- re-encoding the decoded data generated in the decoding step;
- wherein
- in the re-encoding step, the decoded data is re-encoded over the minimum number of division point intervals containing data portions to be altered.
