Information recording medium, information transmission method and device, information reproducing method and device

Abstract

An information recording medium includes a recording area for an auxiliary signal, and a recording area for a main signal. The auxiliary-signal recording area and the main-signal recording area are successively arranged. The main-signal recording area stores first information, second information, and third information. The first information represents plural tunes. The second information includes playback control information for separating the tunes into groups and implementing playback of the tunes group by group. The third information includes interactive data for permitting an access to the first information of the tunes group by group.

Description

technical field [0001] The present invention relates to an information recording medium capable of recording original music and free music, an information transmission device, an information playback device, a recording medium recording a computer program, an information transmission method, an information transmission device and an information transmission medium. Background technique [0002] Since a DVD (Digital Video Disc, Digital Versatile Disc) has a larger capacity than a CD (Compact Disc), it is attracting attention as a record disc for music and the like. However, DVDs can be recorded at a higher density than CDs, and the recording time is more generous. Therefore, it is a problem to use it as a recording medium for music. For example, in addition to the original music as the music source, it can be selectively played back as karaoke and BGM (background music, Background Music), which expands the entertainment methods for users.

Problems solved by technology

[0007] (1) However, as mentioned above, the disk creator can use the disk in various ways, and the user can perform various reproductions. In this way, for the disk creator, there will be such a problem: management It is not easy to record or not to record the free music on which disk, and, for the user, there is a problem that it is impossible to simply know on which disk to record or not to record the free music (first question)

[0008] (2) And, when the original music and the free music are mixed and recorded on the disk or when more than one music that contains the original music is grouped and mixed and recorded on the disk, on the reproducing device side, such a situation will occur. Problem: When reproducing the original music, it cannot be reproduced at the same high speed as the ordinary disk (second problem)
