Abstract

To provide a device capable of determining a delivery destination of an event automatically without requiring choosing operation of an operator. An event entered through an event input means 4 is given to a delivery destination determining means 6 which in turn determines to which of applications AP1, AP2, . . . , APn the given event is to be delivered according to the contents of the event and according to delivery destination determining information stored in a delivery destination determining information storing section, and delivers accordingly. Therefore, the event is delivered to an appropriate application even if the operator does not choose an addressed application.

Claims

1. A digital broadcast receiver that sends an event corresponding to an input from a user to an application, comprising:

a receiver that receives video data, audio data, and the application which are transmitted by a digital broadcast;

a decoder that decodes the video data, the audio data and the application received by the receiver;

a processor that executes the application received by the receiver;

an input section that receives the user input;

an event controlling program that sends the event corresponding to the user input to the executing application; and

a communication controller that receives update data via the Internet to update the event controlling program;

wherein the executing application registers receivable event information that identifies an event that can be received by the executing application in the digital broadcast receiver,

the event controlling program sends the event corresponding to the user input to the executing application when the receivable event information identifies that the event corresponding to the user input can be received by the executing application, and

the event controlling program is updated with the received update data received by the communication controller.

2. The digital broadcast receiver of claim 1, further comprising:

a demultiplexer that demultiplexes the video data, the audio data, and the application which have been multiplexed in the transmitted digital broadcast, wherein the receiver receives the video data, the audio data, and the application multiplexed in the transmitted digital broadcast, the decoder decodes the video data, the audio data and the application demultiplexed by the demultiplexer, and the processor executes the demultiplexed application.

3. The digital broadcast receiver of claim 1, wherein the executing application alters the receivable event information based on a running status of the application.

4. The digital broadcast receiver of claim 1, wherein the input section comprises a key, the event corresponding to the user input being an event corresponding to a depression of the key by the user.

5. The digital broadcast receiver of claim 1, wherein the input section comprises a mouse, the event corresponding to the user input being an event corresponding to a click on the mouse by the user.

6. The digital broadcast receiver of claim 1, wherein the input section comprises a mouse, the event corresponding to the user input being an event corresponding to a movement of the mouse by the user.

7. A program stored on a storage medium that executes instructions for controlling a digital broadcast receiver, comprising:

decoding video data, audio data and an application received by a transmitted digital broadcast;

executing the received application;

receiving an input from a user;

instructing an event controlling program to send an event corresponding to the user input to the executing application; and

updating the event controlling program in accordance with update data received via the Internet;

wherein the executing application registers receivable event information that identifies an event that can be received by the executing application in the digital broadcast receiver,

the event controlling program sends the event corresponding to the user input to the executing application when the receivable event information identifies that the event corresponding to the user input can be received by the executing application.

8. A digital broadcast receiver that sends an event corresponding to an input from a user to an application, comprising:

a receiver that receives the application which is transmitted by a digital broadcast;

a decoder that decodes the application received by the receiver;

a processor that executes the application received by the receiver;

an input section that receives the user input;

an event controlling program that sends an event corresponding to the user input to the executing application; and

a communication controller that receives update data via the Internet to update the event controlling program;

wherein the event controlling program sends the event corresponding to the user input to the executing application when receivable event information identifies that the event corresponding to the user input can be received by the executing application, and

the event controlling program is updated with the received update data received by the communication controller.

9. The digital broadcast receiver of claim 8, wherein the application is multiplexed with at least one of video data and audio data to form the transmitted digital broadcast, a demultiplexer demultiplexing the application and the at least the one of video data and audio data which have been multiplexed in the transmitted digital broadcast, wherein the receiver receives the application and the at least one of video data and audio data, multiplexed in the transmitted digital broadcast, the decoder decodes the application and the at least one of video data and audio data demultiplexed by the demultiplexer, and the processor executes the demultiplexed application.

10. The digital broadcast receiver of claim 8, wherein the executing application alters the receivable event information based on a running status of the application.

11. The digital broadcast receiver of claim 8, wherein the input section comprises a key, the event corresponding to the user input being an event corresponding to a depression of the key by the user.

12. The digital broadcast receiver of claim 8, wherein the input section comprises a mouse, the event corresponding to the user input being an event corresponding to a click on the mouse by the user.

13. The digital broadcast receiver of claim 8, wherein the input section comprises a mouse, the event corresponding to the user input being an event corresponding to a movement of the mouse by the user.
