Description of the Related Art In recent years, with the development of large-capacity DVDs (digital video disks), various types of so-called multimedia information such as digital video information (including still images) and audio information have been developed. Reproduction systems have been proposed. Hereinafter, digital video information (including still images) and audio information are integrated and referred to as AV information.

[0003] A playback system specifically has a DVD drive, and performs playback processing of AV information recorded (recorded) on a DVD set in the DVD drive, for example, a display of a television receiver or a personal computer. This is a device corresponding to a video player or a video deck having a function of displaying on a screen.

[0004] DVDs usually have the MPEG (movi
ng picture coding experts
AV information encoded by a moving image encoding method called “group 2” is multiplexed with audio information and recorded. The reproduction system reproduces AV information continuously on a screen by reproducing stream information in units of a predetermined coded stream (continuous bit data string) corresponding to a specified title (for example, a movie) from a DVD.

By the way, the above-mentioned reproduction system is a DVD.
It has a communication function for connecting not only to a drive but also to a computer network such as the Internet, and can access stream information called a desired Web page (home page) from a Web server which is a resource on the network. System has been proposed.

[0006]

As the reproduction system as described above, there has been proposed an integrated system that can be connected to a computer network and use resources (such as a Web server) on the network. With such an integrated system, not only the playback processing of the title recorded on the DVD, but also the related information (arbitrarily set information, not necessarily the attribute information Does not only mean)
Can be obtained from a resource on the network and displayed on a display screen.

[0007] As a specific example, when a scene (stream information) where a meal is being eaten at a restaurant is displayed on a display screen by reproduction of a stream read from a DVD, for example, the user can change the information about the restaurant as needed. It is a system that can obtain related information. The related information is prepared in, for example, a Web server on a network,
If the user simply clicks, for example, a Web mark displayed on the display screen with a mouse, the system is linked to the Web server and related information (that is, a Web page) is displayed on the display screen. It is convenient. With such a system, the user can play the title and, at the time of request, view related information relating to the scene (stream information) such as a restaurant location and menu contents on the screen.

Accordingly, an object of the present invention is to provide a system for reproducing AV information from a storage medium such as a DVD, which not only reproduces a normal title but also transmits related information relating to predetermined stream information to a computer network resource or the like. To provide a playback system that can be easily obtained by simple operations.

Specific means of this function include reading means for reading resource use information for using the resource from a storage medium such as a DVD, and control means for executing access to related information from the resource using the resource use information. There is.

With a playback system having such a network link function, the user may need to play a certain title from a DVD while displaying specific stream information (scene). For example, with an input instruction operation such as a mouse click operation, related information prepared in advance for the scene can be displayed on the screen. The specific stream information has related information prepared in advance, and can be identified, for example, by displaying specific input information such as a Web mark on a screen. The control means uses resources prepared in advance in response to an input instruction operation using the specific input information and uses resources (W
(e.g., web server), and accesses related information related to the stream information. The resource usage information has link information (access information) for linking to resources on the network, for example, for each stream information in stream units.

[0011] As a specific example, when, for example, a scene where a meal is being eaten at a restaurant is displayed on a display screen by playing back a stream read from a DVD, the user can display, for example, a Web mark on the screen as necessary. Click with the mouse. In response to the input instruction operation, the related information related to the restaurant is linked to a prepared Web server, and the related information (Web page or home page) accessed from this Web server is displayed on the screen. Thus, the user can view the scene of the restaurant reproduced on the screen, and also can view the related information such as the location of the restaurant and the menu on the screen.

Another aspect of the present invention is a system in which related information is prepared on, for example, a DVD, and the control means reads the relevant information from the DVD and reproduces the related information on a screen in response to a user's input instruction operation. Further, the related information may be stored in a storage medium different from the DVD storing the title. That is, the system is prepared for each stream information by accessing another storage area or another storage medium of the DVD instead of linking to resources on the network in response to a user's input instruction operation. Related information can be read on the screen.

According to such a reproducing system, when a user requests commentary explanatory information of a scene while reproducing a title such as a movie, the reproducing system is prepared on a DVD together with the title in advance. Thereby, the explanation information can be reproduced. If a method of accessing a storage medium different from the storage medium of the title is used, updating such as addition of commentary explanation information is possible.
