Description

Method for making and reproducing a list for editing of optical discs

The present invention relates to a method for creating an edit list through a play list for an inserted optical disc and playing the same.

In general, since an optical disc device such as a DVD player provides an editing function for an inserted optical disc, the user can select a title list (= playlist, for example, number 1 track) for the inserted optical disc (DVD) as shown in FIG. By selecting and designating a desired track (title) from (Track 1) to 50 tracks (Track 50), an edit list as shown in FIG. 1 is created, and the edit list thus created is made until the optical disc is ejected. Allows the user to selectively play only songs in the edit list (eg, songs 1, 2, 11, 18, .., 32, 47).

However, conventionally, when creating an edit list, it is difficult to identify the contents of a song only through a playlist, so that a user may grasp the songs of the playlist through a normal play or an intro play. It takes a lot of time to create the edit list, and in case of intro playback, it plays only for a predetermined time (about 5 seconds) from the beginning of each song, which is mainly accompaniment of the song, so it is not easy to identify the contents of the song. However, if it is difficult to grasp the contents of the song through such an intro playback, the user has to comprehend the song through general playback and then create an edit list, which also takes a lot of time and hassle.

In addition, to perform a quick song search for the edit list created by the user, an intro playback is performed. As described above, the intro playback is not simply a playback of a spotlight part, that is, a climax part of each song, Since this is an accompaniment sound, this intro playback makes it difficult for the user to find out the contents of the song, even if the song is selected by the user as an edit list. There was a problem of becoming inefficient.

In addition, since the edit list thus prepared is not stored even when the edit list is created, the user cannot know the edit list previously created by the user when the optical disc is ejected and then inserted again. There was a problem of hassle and waste of time to recreate the edit list.

Accordingly, the present invention was created to solve the above problems, and by playing the spotlight portion of the currently active song for the playlist of the optical disc, it is possible to easily and quickly grasp the contents of the user and thereby create the edit list. To lose,

In addition, the present invention, by reproducing the spotlight portion of the currently active song to the edit list of the optical disc, so that the user can easily grasp the songs written in the edit list to facilitate the song search and song playback operation,

In addition, the present invention, by storing the edit list created by the user with the identification code (ID) of the optical disk, to create and play back the edit list of the optical disk to the user to eliminate the hassle of having to re-create the edit list for the same disk The purpose is to provide a method.
