Method and apparatus for enabling an application to run with a program

The present invention relates to the field of optical storage, and more particularly to a method and apparatus for enabling an application to operate in conjunction with a program.

With the development of optical storage technology, programs stored on optical discs have long been able to be played back in a fixed order. Enabling users to interact interactively is almost a must-have feature in disc playback devices, and network linking has become an important part of emerging features in a variety of disc formats. For example, the enhanced DVD (Enhanced Digital Versatile Disc) disc format defines good interactive operation functions and network link functions.

These functions are generally implemented by way of menu navigation. The disc playback device responds to certain imperative trigger events (such as buttons) of the user according to the menu to implement the corresponding functions. All interactive operating functions and web linking functions are determined when the disc is edited.

As a new generation of disc formats, Blu-ray Disc features a wide range of unparalleled storage capacity, as well as a rich and flexible personalized interactive feature and web link feature. As a fully object-oriented application, Java applications are introduced into the Blu-ray Disc format, which runs on a variety of platforms, making it ideal as a tool to enable users to use more personalized interactive features and web links. Features. How to enable a Java application to run with a CD program to determine the time and effect is a concern.

The traditional method of managing the correspondence between Java applications and the programs being played has many applications in the multimedia home platform MHP (Multimedia Home Platform). In the MHP, programs and Java applications are instantly sent to the user via the code stream. The server-side editors send the AIT (Application Information Table) table and the Java application program to match the program playback according to the scheduled time, and no contact information is needed between the program and the application. The AIT form contains information about the Java application, such as storing information, type information, running resource requirements information, running startup information, running end information, and so on. The client interprets the received AIT form and controls the corresponding Java application to run according to the related information, and displays the comprehensive effect brought by the program and the corresponding application to the user.

For Blu-ray discs, the programs and corresponding Java programs are stored on the disc or on the network, and are recorded or requested to be downloaded by the disc playback device, unlike the programs and Java programs in the MHP. The terminal sends it instantly, and the client receives it immediately. Therefore, in the Blu-ray Disc format, the Java application cannot run the AIT in real time by the user in the MHP, and immediately interpret the AIT to run to implement the corresponding functions. Moreover, in the Blu-ray Disc format, a CD-ROM program may require the support of several applications, and a Java program may also serve the playback of multiple CD-ROM programs. The application is more complicated for the playback of the CD-ROM program.

The disc playback device can neither download all the Java applications that may be used to the memory when starting to play the disc, nor can it find the Java application that should be running when playing a disc program and affect the playback effect.

Therefore, there is a need to provide a method and apparatus for enabling an application to operate in conjunction with a program to solve the problem of cooperation between application running and program playback.

The problem to be solved by the present invention is to provide a method and apparatus for enabling an application to operate in conjunction with a program to overcome the deficiencies of the prior art.
