Abstract

The embedded program comprises a part of the function of the lava 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 lava program on completion of the Java program start-up process.

Claims

1. A program executing apparatus that has a Java VM for executing a Java program and has an embedded program having a partial function that is a part of a function of the Java program, the program executing apparatus comprising:

an execution unit operable to execute the embedded program and the Java VM; and

an information provision unit operable to provide the Java program with information that has been generated as a result of running of the embedded program.

2. The program executing apparatus according to claim 1, wherein the information provision unit provides the Java program with the information that has been generated as a result of running of the embedded program, before the Java program uses the information provision unit.

3. The program executing apparatus according to claim 1, wherein the information provision unit provides the Java program with the information that has been generated as a result of running of the embedded program, before the Java program is activated.

4. The program executing apparatus according to claim 1, wherein the information provision unit provides the Java program with the information that has been generated as a result of running of the embedded program, before the embedded program is terminated.

5. The program executing apparatus according to claim 1, further comprising an embedded program termination instruction unit operable to be used by the Java program to give an instruction to terminate the embedded program.

6. A program executing apparatus comprising:

a Java VM that executes a Java program;

an input unit operable to accept an input;

a receiving unit operable to receive a broadcast;

a channel reproduction unit operable to reproduce a channel included in the broadcast received by the receiving unit;

a reproduction program that indicates a channel to be reproduced to the channel reproduction unit, based on an instruction from the input unit;

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

an information provision unit operable to provide the Java program with a channel that is last indicated by the reproduction program.

7. The program executing apparatus according to claim 6, further comprising:

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

a second storage unit operable to store the reproduction program.

8. The program executing apparatus according to claim 6,

wherein the channel reproduction unit reproduces video and audio included in the channel.

9. The program executing apparatus according to claim 6, further comprising a service reproduction unit operable to reproduce video, audio, and a Java program that are included in the channel.

10. The program executing apparatus according to claim 9,

wherein the service reproduction unit is executed by the Java VM partially or fully, and accepts a service to be reproduced from the lava program.

11. The program executing apparatus according to claim 10,

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

the reproduction unit 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.

12. The program executing apparatus according to claim 9, further comprising a service acceptance start notification unit operable to notify that the service reproduction unit has started to accept a service to be reproduced.

13. A program executing apparatus comprising:

a Java VM that executes a lava program;

an input unit operable to accept an input;

a receiving unit operable to receive a broadcast;

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

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

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

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

an execution unit operable to execute the reproduction program and the lava program; and

an information provision unit operable to provide the Java program with the channel that is last indicated by the reproduction program to the channel identifier accepting unit.

14. The program executing apparatus according to claim 13, further comprising a channel identifier storage unit operable 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.

15. A computer-readable recording medium in which a program capable of functioning as the following units is stored:

a Java VM that executes a Java program;

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

an execution unit operable to execute the embedded program and the Java VM; and

an information provision unit operable to provide the Java program with information that has been generated as a result of running of the embedded program.
