摘要：
A new navigation function is added to a legacy DVD-Video. A player unit plays back recorded contents, that include video contents or AV contents and ENAV contents associated with contents (menu, chapter) of the video contents, from a DVD-Video disc. The video contents of the DVD disc are played back by a video playback engine. The ENAV contents of the DVD disc are played back by an ENAV engine. The ENAV engine controls playback of the ENAV contents and that of the video contents in combination, connection, and/or synchronism with each other according to the played-back contents of the ENAV contents.
