Abstract

A method of receiving a broadcast service is provided. The method includes receiving uncompressed audio or video content, obtaining information regarding a channel of the uncompressed audio or video content on the basis of a part of the uncompressed audio or video content, and obtaining content and trigger information for the broadcast service by using the obtained information.

Claims

1. A method of receiving a broadcast service in a receiving apparatus, the method comprising:

receiving a broadcasting signal through a tuner;

receiving an uncompressed AV content, other than the broadcasting signal, through a receiving unit;

extracting a signature from an uncompressed audio or video content, wherein the signature is a video frame or an audio sample;

transmitting a first request including the signature to a server;

obtaining a response corresponding to the first request, wherein the response includes content information regarding the uncompressed AV content, timestamp information for the signature, period information for requesting trigger information and information for deleting an enhanced service;

obtaining trigger information for the enhanced service by using the response, wherein the trigger information includes at least one of trigger time, an identifier, and a trigger action;

outputting the enhanced service based on the response; and

deleting the enhanced service based on the second information for deleting the enhanced service,

wherein obtaining the trigger information comprises,

transmitting a second request for the trigger information according to the period information, and

receiving the trigger information, when the response indicates a first mode.

2. The method of claim 1, wherein the information for deleting the enhanced service includes an expiration date of the enhanced service.

3. The method of claim 1, wherein the outputting the enhanced service comprises:

executing the trigger action for the enhanced service in the trigger time.

4. The method of claim 1, wherein the trigger action comprises at least one of a preparation trigger action, an execution trigger action and a termination trigger action.

5. The method of claim 4, wherein the trigger time is synchronized with the uncompressed AV content.

6. The method claim 1, further comprising:

storing the enhanced service; and

outputting the stored enhanced service again, before deleting the enhanced service.

7. A receiving apparatus comprising:

a tuner for receiving a broadcasting signal;

a receiving unit for receiving uncompressed AV content; and

a control unit for extracting a signature from an uncompressed audio or video content,

wherein the signature is a video frame or an audio sample, transmitting a first request including the signature to a server, obtaining a response corresponding to the first request, wherein the response includes content information regarding the uncompressed AV content, timestamp information for the signature, and information for deleting an enhanced service, obtaining trigger information for the enhanced service by using the response, outputting the enhanced service based on the response and deleting the enhanced service based on the information for deleting the enhanced service,

wherein the response includes period information for requesting trigger information,

wherein the control unit transmits a second request for the trigger information according to the period information, and receives the trigger information, when the response indicates a first mode,

wherein the trigger information includes at least one of trigger time, an identifier, and a trigger action.

8. The receiving apparatus of claim 7, wherein the second information for deleting the enhanced service includes an expiration date of the enhanced service.

9. The receiving apparatus of claim 7, wherein the control unit executes the trigger action for the enhanced service in the trigger time.

10. The receiving apparatus of claim 7, wherein the trigger action comprises at least one of a preparation trigger action, an execution trigger action and a termination trigger action.

11. The receiving apparatus of claim 10, wherein the trigger time is synchronized with the uncompressed AV content.

12. The receiving apparatus of claim 7, wherein the control unit stores the enhanced service and outputs the stored enhanced service again, before deleting the enhanced service.
