Abstract

The embedded program comprises a part of the function of the Java program. The embedded program executes the part of the function during the start-up processing period of Java program. Thus, the start-up time appears to be shortened. Further, the present invention provides the information regarding the action state of the embedded program to the Java program, thereby enabling a consistent execution of the Java program on completion of the Java program start-up process.

Claims

1. A broadcast receiving apparatus comprising:

a Java VM that executes a Java program;

a downloader configured to download the Java program;

an input unit configured to accept an input;

a receiver configured to receive a broadcast;

a channel reproduction unit configured to reproduce a channel included in the broadcast received by the receiver;

a reproduction program that comprises an embedded program that notifies the channel reproduction unit of a channel to be reproduced, based on an instruction from the input unit;

an execution unit configured to execute the reproduction program and the Java VM; and

an information provision unit configured to provide the Java program with a channel identifier of a channel that is last notified to the channel reproduction unit by the reproduction program, the Java program being executed by the Java VM,

wherein the information provision unit includes a storage unit that temporarily stores the channel identifier to be transmitted from the reproduction program to the Java program, the channel identifier being transmitted through the storage unit.

2. The broadcast receiving apparatus according to claim 1, further comprising:

a first storage unit configured to store the Java program; and

a second storage unit configured to store the reproduction program.

3. The broadcast receiving apparatus according to claim 1, wherein the channel reproduction unit reproduces video and audio included in the channel.

4. The broadcast receiving apparatus according to claim 1, wherein the broadcast includes a Java program, and the broadcast receiving apparatus further comprises a service reproduction unit configured to reproduce video, audio, and the Java program that are included in the channel.

5. The broadcast receiving apparatus according to claim 4, wherein the service reproduction unit is at least partially executed by the Java VM, and accepts a service to be reproduced from the Java program.

6. The broadcast receiving apparatus according to claim 5,

wherein the service reproduction unit accepts the service to be reproduced from the reproduction program, and

the reproduction program reproduces the channel using the channel reproduction unit when the service reproduction unit does not accept the service to be reproduced, and reproduces the channel using the service reproduction unit when the service reproduction unit accepts the service to be reproduced.

7. The broadcast receiving apparatus according to claim 4, further comprising a service acceptance start notifier configured to notify that the service reproduction unit has started to accept a service to be reproduced.

11. The broadcast receiving apparatus according to claim 1, wherein the information provision unit provides the Java program with information when the Java program is activated, the information having been generated as a result of running the embedded program before the Java program is activated.

8. A broadcast receiving apparatus comprising:

a Java VM that executes a Java program;

a downloader configured to download the Java program;

an input unit configured to accept an input;

a receiver configured to receive a broadcast;

a channel reproduction unit configured to reproduce video and audio included in a channel that is included in the broadcast received by the receiver;

a service reproduction unit configured to reproduce video, audio and data included in the channel that is included in the broadcast received by the receiver

a channel identifier accepting unit configured to receive an identifier of a channel to be reproduced and to reproduce the channel using the service reproduction unit when it is possible for the service reproduction unit to reproduce a channel, and to reproduce the channel using the channel reproduction unit when it is impossible for the service reproduction unit to reproduce a channel;

a reproduction program comprising an embedded program that notifies the channel identifier accepting unit of the identifier of the channel to be reproduced, based on an instruction from the input unit;

an execution unit configured to execute the reproduction program and the Java program; and

an information provision unit configured to provide the Java program with the identifier of the channel that is last notified to the channel identifier accepting unit by the reproduction program, the Java program being executed by the Java VM.

9. The broadcast receiving apparatus according to claim 8, further comprising a channel identifier storage unit configured to store the identifier of the channel accepted by the channel identifier accepting unit,

wherein the channel identifier accepting unit provides the service reproduction unit with the identifier of the channel stored in the channel identifier storage unit, when it becomes possible for the service reproduction unit to reproduce a channel, and reproduces the channel.

10. A computer-readable recording medium storing a computer program, comprising:

a Java VM that executes a Java program; and

an embedded program having a partial function that is a part of a function of the Java program;

whereby information that has been generated as a result of running of the embedded program can be provided to the Java program by an information provision unit.
