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 uncompressed audio or video content;

extracting a signature from video frames or audio samples of the uncompressed audio or video content;

transmitting a query including the signature to a server;

obtaining a response based on the query, wherein the response includes period information for requesting trigger information; and

obtaining trigger information by using the obtained response,

wherein the trigger information includes at least one of trigger time, an identifier for a Triggered Declarative Object (TDO) and a trigger action,

wherein the obtaining trigger information comprises,

transmitting a request for 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 obtaining trigger information comprises,

obtaining the trigger information, when signaling information changes, when the response indicates a second mode.

3. The method of claim 1, further comprising

executing the trigger action for an object corresponding to the identifier of the TDO at 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 1, wherein the trigger time is synchronized with the uncompressed audio or video content.

6. The method of claim 1, wherein the obtaining trigger information comprises, when the response indicates a second mode, to receive the trigger information when signaling information changes.

7. A receiving apparatus comprising:

a receiving unit to receive uncompressed audio or video content; and

a service management unit to extract from video frames or audio samples of the uncompressed audio or video content, transmit a query including the signature to a server, obtain a response based on the query and obtain trigger information by using the obtained response,

wherein the response includes period information for requesting trigger information,

wherein the trigger information includes at least one of trigger time, an identifier for a Triggered Declarative Object (TDO) and a trigger action,

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

8. The receiving apparatus of claim 7,

wherein the service management unit receives the trigger information when signaling information changes, when the response indicates a second mode.

9. The receiving apparatus of claim 8, wherein the service management unit obtains a trigger time related to the trigger information and

the receiving apparatus further comprises a control unit that executes the trigger action for an object corresponding to the identifier of the TDO at the trigger time.

10. The receiving apparatus of claim 9, 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 9, wherein the trigger time is synchronized with the uncompressed audio or video content.
