[0001]

The present invention relates to a music CD.
And data stored in a storage medium such as a VideoCD that records moving images and the like, and MPEG data and AVI stored in a storage device such as a hard disk of a computer such as a personal computer and a workstation.
Data synchronous reproduction system, data synchronous reproduction method, and data synchronous reproduction for synchronously reproducing related data associated with the continuous media data in accordance with the reproduction progress state of continuous media data such as data, video, music, and audio The present invention relates to a recording medium on which a program is recorded.

[0002]

2. Description of the Related Art In conjunction with the reproduction of continuous media data such as video, music, and audio stored in a storage medium such as a CD-ROM or a hard disk of a computer, a related media associated with the reproduced continuous media data is reproduced. As a configuration of a conventional data synchronous reproduction system for synchronously reproducing data, a data synchronous reproduction system having a configuration shown in FIG. 5 is known.

FIG. 5 shows music data stored in a continuous media data storage medium 41 such as a CD as continuous media data, and a related data storage medium 42 for storing related data, which is a WWW (World Wide) existing on a network.
A web server is used as an example, and the homepage information on the WWW is assumed to be related data of music data, and the music data is output to the output device 45 of the personal computer. 1 is a block diagram of a data synchronous reproduction system of FIG.

In the conventional data synchronous reproduction system shown in FIG. 5, not only continuous media data (music data) but also related information as information on related data associated with the continuous media data is stored in the same continuous media data storage medium ( CD) 41 in advance. The continuous media data reproducing device 43 reproduces the continuous media data stored in the continuous media data storage medium 41 and outputs the data to an output device 45 such as a personal computer. From the related information received from the continuous media data storage medium 41, the related data reproducing device 44 uses the data (homepage) stored in the corresponding related data storage medium (WWW server) 42 as personal data of the continuous media data as a personal computer. And the like. With this configuration, it is possible to synchronously reproduce the related data associated with the continuous media data.

[0005]

However, in the conventional data synchronous reproduction system described above, the timing for reproducing the related data is limited to the time when the reproduction of the continuous media data associated with the relevant data is started, and the continuous media data is not reproduced. The related data cannot be synchronously reproduced one after another according to the reproduction progress state of the data. That is, for example, there is a problem that it is not considered at all that reproducing related data one minute after the start of reproduction of continuous media data and reproducing another related data two minutes later.

In the above-described conventional data synchronous reproduction system, in the case of a storage medium whose contents cannot be modified, such as a commercially available CD, related data can be associated with continuous media data only by manufacturing the storage medium. There is a problem that a third party other than the storage medium creator cannot associate the related data with the continuous media data.

[0007] Further, in the above-mentioned conventional data synchronous reproduction system, in the case of a storage medium whose contents cannot be changed, such as a CD, there is a problem that related data associated with continuous media data cannot be changed later.

In view of the above, it is an object of the present invention to provide a data synchronous reproduction system and a computer readable recording medium on which a data synchronous reproduction program is recorded, which solves the above-mentioned problems of the prior art. And

Data. Corresponding to the ID number of each music CD,
The scenario data is stored in one or more scenario data storage media 17.

Data 102 is reproduction progress status identification information 102 corresponding to a signal indicating the reproduction progress status output from the continuous media data reproduction device 13. In the present embodiment, the reproduction progress time of the music CD is described. However, as described above, since the reproduction progress time corresponds to the signal indicating the reproduction progress state, C is used.
A signal representing the state of D can also be described. The detailed description of the reproduction progress state identification information 102 will be described later.

The data 103 includes reproduction progress state identification information 1

When it is in the state, the pointer 103 corresponding to the reproduction progress state identification information is output to the related data reproducing device 22. For example, when the synchronization-related data selection device 20 receives, from the CD reproduction device 13a, a signal indicating the reproduction time “00:10:00” as the signal indicating the reproduction progress state,
Since the reproduction time “00:10:00” exists in the reproduction progress state identification information of the scenario data, “http: // ww” is used as a pointer corresponding to the reproduction time “00:10:00”.
w.nec.co.jp/index02.html "
Output to 2.

The related data reproducing device 22 performs a process according to the pointer received from the synchronization related data selecting device 20, and displays the processing result on the display 28a as related data corresponding to the state of the music CD 11a. In the case of this example, the input pointer is the URL of the homepage on the WWW server, "http://www.nec.co.
jp / index02.html ”, the W corresponding to this URL
The WW server 24a is searched, and the information of the searched home page is displayed on the display 28a. Therefore, the state of the music CD 11a, that is, in this embodiment, the reproduction time of the CD is "00:00:00" → "00:10:00" →
When “00:20:00” → ... elapses, “http://www.nec.co.jp” which is URL information indicating a homepage on the WWW
/index01.html"→"http://www.nec.co.jp/index02.h
tml "→" http://www.nec.co.jp/index03.html "→…
Are sequentially output to the related data reproducing device 22 as a pointer, and the related data reproducing device 22 displays a homepage according to the URL information input as the pointer as the relevant data of the music CD 11a on the display 28a.
To be displayed.
