Abstract:
1. An information processing apparatus for splicing first compressed image data with second compressed image data, the apparatus comprising: decoding means for decoding a first predetermined section including a first editing point set to the first compressed image data to produce first image data and decoding a second predetermined section including a second editing point set to the second compressed image data to produce second image data; re-encoding means for splicing the first and second image data to each other at the first editing point and the second editing point and re-encoding the resulting image data to produce re-encoded image data; control means for controlling the re-encoding process of said re-encoding means so that a picture type of each picture in the re-encoded image data that is positioned later in time in a display order than an I picture or a P picture is the same as a picture type of a corresponding picture of the first compressed image data and the second compressed image data; and editing means for switchably outputting the first and second compressed image data and the re-encoded image data produced by said re-encoding means to produce edited compressed image data, wherein the control means controls the re-encoding process of said re-encoding means so that a buffer occupancy of a first I or P picture that follows a top I picture of the second compressed image data is the same as a buffer occupancy of a first I or P picture that follows a top I picture of the edited compressed image data, the top I picture of the second compressed image data is a first I picture that follows the second predetermined section in the second compressed image data, and the top I picture of the edited compressed image data is an I picture that corresponds to the top I picture of the second compressed image data.
