An information processing apparatus and method for splicing first compressed image data with second compressed image data. The method includes performing a decoding process for a first decoding interval that includes a first editing point set to the first compressed image data to produce a first non-compressed image signal. A second decoding process includes a second editing point set to the second compressed image data to produce a second non-compressed image signal. A re-encoding process re-encodes an interval of a third non-compressed image signal and the first and second non-compressed image signals are spliced at the first and second editing points to produce third compressed image data.

An information processing apparatus and method is disclosed by which an encoder having no reference picture inputting function can be used to edit compressed image data of the Open GOP structure. First and second non-compressed image signals each obtained by decoding a predetermined section including an editing point set to compressed image data are joined at the editing points to produce a third signal. The third signal is re-encoded to produce re-encoded image data using, as reference pictures to be used to re-encode B pictures at the top and the last of the third signal, data obtained by re-encoding the third signal corresponding to each of the reference pictures as an I or P picture and decoding the re-encoded I or P picture in the inside of the encoder.
