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.
