Slide show generation on DVD-video compatible discs including DVD+RW and DVD+R

摘要

A method and a device generate a DVD-Video compatible data structure from still pictures so as to create a slide show, where the data structure is compatible with the DVD+RW and DVD+R specifications. In one embodiment, a set of Ni video object units (VOBUs) is generated for each still picture, where each of the VOBUs include one video picture derived from the original still picture and a video gap. The video pictures of the Ni VOBUs only differ by their time stamps. Consequently, the DVD-Video compatible data structure is easy and fast to author. The DVD-Video compatible data structure has a low bitrate, and the presentation time of each picture can be adapted by setting the number Ni and/or the length of the video gap.
