Description

The present invention relates to a chapter and a title recorded on an optical disc.
The present invention relates to an optical disc playback apparatus that can graphically display a video on a video display device (TV) connected to the optical disc playback apparatus and determine a playback start title and chapter, and a playback position determination method for the optical disc.

Recently, an optical disk reproducing apparatus that records software such as movies and sports on an optical disk and reads it out using an optical pickup has become widespread. The optical disk is a DVD (Digital Versat
ile Disc) is widely used.

The DVD is composed of a subtitle chapter (Chapter) and one or more chapter titles (Title) as a unit of video reproduction. For example, a DVD usually has a plurality of titles, and each title is composed of a plurality of chapters.

When playing back the video recorded on the DVD by the DVD playback device, when the DVD is inserted and played back, the DVDs are played back in the order instructed. For example, in the case of a movie, playback starts from the opening.

If the user stops playing in the middle of playback, if the title number and chapter number that were being played back are memorized, it will be immediately after or close to the end after relying on the title number and chapter number. Playback from a place can be performed easily.

When the playback start position is determined by the title and chapter, the user can select the title and chapter by using the input key provided on the front of the DVD playback device while watching the display on the monitor of the DVD playback device and / or the TV screen. Enter the title number and chapter number using the input keys on the remote controller.

  FIGS. 5A and 5B show title and chapter search screens appearing on the TV screen.

In the title and chapter search screen shown in FIG. 5, a title (TITLE) 91 and a chapter (CHAPTER) 92 are displayed. In the space behind the title 91 and the chapter 92, a 2-digit input unit 911 for inputting a title number and a 2-digit input unit 921 for inputting a chapter number are provided. Here, for the title and chapter, two-digit input sections 911 and 921 are shown, but there may be three digits each.

When a title and a chapter are input using an input key provided on the front surface of the DVD playback apparatus or an input key of a remote controller, playback is started from the head of the input chapter of the input title. For example, when the chapter 2 of the title 2 is selected, it is displayed as shown in FIG. Then, the title 2
Playback starts from the beginning of the chapter 23. As can be seen from FIGS. 5 (A) and 5 (B), the search is possible even in the reproduction time.
