Abstract
One or more video objects are recorded on an optical disc. When a user indicates a linking edit that links sections of the video objects, video object units (VOBUs) that include picture data at the end of a former section and VOBUs that include picture data at the start of a latter section are read from the optical disc and the audio packs and video packs are separated from these read VOBS. Next, the video packs are re-encoded and some of the audio packs that were originally in the former section are multiplexed into the latter section. The result of the multiplexing is then recorded onto the optical disc.
