Abstract

Disclosed herein is a receiving device for receiving an AV content broadcast by a broadcasting wave, including: an obtaining section adapted to obtain a description document described in a predetermined computer language for displaying another content different from the AV content; a determining section adapted to determine whether the obtained description document is managed by a broadcaster which broadcasts the AV content or is managed by a different operator other than the broadcaster; and a controlling section adapted to control execution of the obtained description document in response to a result of the determination by the determining section.

Claims

1. A receiving device for receiving an AV content broadcast by a broadcasting wave, comprising:

an obtaining section adapted to obtain a description document described in a predetermined computer language for displaying another content different from the AV content;

a determining section adapted to determine whether the obtained description document is managed by a broadcaster which broadcasts the AV content or is managed by a different operator other than the broadcaster; and

a controlling section adapted to control execution of the obtained description document in response to a result of the determination by said determining section.

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

a trigger detecting section adapted to detect trigger information relating to control of the description document transmitted together with the AV content and executed in an interlocked relationship with the progress of the AV content; and

wherein

said obtaining section obtains the description document from an information processing device managed by the broadcaster based on the detected trigger information, and

said determining section determines that the description document obtained from the information processing device is managed by the broadcaster.

3. The receiving device according to claim 1, wherein

said obtaining section obtains, when a description document which can be executed solely without interlocking with the AV content, the description document from an information processing device managed by the broadcaster, and

said determining section determines that the description document obtained from the information processing device is managed by the broadcaster.

4. The receiving device according to claim 1, wherein

said obtaining section obtains, when a description document which can be executed only by a specific application program, the description document from a different information processing device managed by the different operator, and

said determining section determines that the description document obtained from the different information processing device is managed by the different operator.

5. The receiving device according to claim 1, further comprising:

an executing section adapted to execute the obtained description document, and

said controlling section

controls, when it is determined that the description document is managed by the broadcaster, said executing section to operate in a first management mode in which said executing section can perform a specific process determined in advance, but

controls, if it is determined that the description document is managed by the different operator, said executing section to operate in a second management mode in which said executing section cannot perform the specific process.

6. The receiving device according to claim 5, wherein

said determining section determines, when said executing section operates in the first management mode, every time the description document is obtained, whether the obtained description document is managed by the broadcaster or the different operator, and

said controlling section controls, when it is determined that the description document is managed by the different operator, said executing section, which is operating in the first management mode, to operate in the second management mode.

7. The receiving device according to claim 5, wherein

said controlling section controls, when a predetermined operation is performed while said executing section is operating in the second management mode, said executing section, which is operating in the second management mode, to operate in the first management mode.

8. The receiving device according to claim 1, wherein

said obtaining section obtains the description document transmitted utilizing a predetermined broadcasting waveband of a digital television broadcasting signal of the broadcasting wave.

9. A receiving method by a receiving device, comprising:

obtaining a description document described in a predetermined computer language for displaying another content different from an AV content broadcast by a broadcasting wave;

determining whether the obtained description document is managed by a broadcaster which broadcasts the AV content or is managed by a different operator other than the broadcaster; and

controlling execution of the obtained description document in response to a result of the determination.

10. A program for controlling a receiving device and causing a computer of the receiving device to execute a process comprising:

obtaining a description document described in a predetermined computer language for displaying another content different from an AV content broadcast by a broadcasting wave;

determining whether the obtained description document is managed by a broadcaster which broadcasts the AV content or is managed by a different operator other than the broadcaster; and

controlling execution of the obtained description document in response to a result of the determination.
