Abstract

The present invention provides a method for transmitting a broadcast signal. A method for transmitting a broadcast signal, according to one embodiment of the present invention, comprises the steps of: generating service guide information, which includes information for accessing a broadcast service, and content data, wherein the service guide information includes a service fragment which displays information related to the broadcast service; encoding the service guide information and the content data which have been generated; and transmitting the service guide information and the content data which have been encoded.

Claims

1. A method of transmitting broadcast signals, the method comprising:

generating service guide information including access information of a broadcast service,

wherein the service guide information include a service fragment having information about the broadcast service and a content fragment having information about content data of the broadcast service,

wherein the content fragment further includes a content-level PrivateExt element having component information of the content data,

wherein the component information includes information for a component in the broadcast service, and

wherein the component is one of a video component, an audio component, and a closed caption component (CC);

encoding the content data;

transmitting the encoded content data; and

transmitting the generated service guide information.

2. The method of claim 1, wherein the service fragment includes service type information indicating a type of the broadcast service, and

wherein the type of the broadcast service includes a Linear Service for providing content in real time or an App-based Service based on an application.

3. The method of claim 1, wherein the component information includes a component role information indicating a role of the component and a language information representing a language in which the component is available.

4. The method of claim 3, wherein the role of the component is at least one of a three dimensional (3D) video left or right view, a 3D video depth information, a music audio and a dialog audio.

5. An apparatus for receiving a broadcast signal, the apparatus comprising:

a receiver configured to receive content data and service guide information including access information of a broadcast service,

wherein the service guide information include a service fragment having information about the broadcast service and a content fragment having information about content data of the broadcast service,

wherein the content fragment further includes a content-level PrivateExt element having component information of the content data,

wherein the component information includes information for a component in the broadcast service, and

wherein the component is one of a video component, an audio component, and a closed caption component (CC); and

a decoder configured to decode the content data and the service guide information.

6. The apparatus of claim 5, wherein the service fragment includes service type information indicating a type of the broadcast service, and

wherein the type of the broadcast service includes a Linear Service for providing content in real time or an App-based Service based on an application.

7. The apparatus of claim 5, wherein the component information includes a component role information indicating a role of the component and a language information representing a language in which the component is available.

8. The apparatus of claim 7, wherein the role of the component is at least one of a three dimensional (3D) video left or right view, a 3D video depth information, a music audio and a dialog audio.

9. An apparatus for transmitting broadcast signals, the apparatus comprising:

a generator configured to generate service guide information including access information of a broadcast service,

wherein the service guide information include a service fragment having information about the broadcast service and a content fragment having information about content data of the broadcast service,

wherein the content fragment further includes a content-level PrivateExt element having component information of the content data,

wherein the component information includes information for a component in the broadcast service, and

wherein the component is one of a video component, an audio component, and a closed caption component (CC);

an encoder configured to encode the content data; and

a transmitter configured to transmit the encoded content data and the generated service guide information.

10. The apparatus of claim 9, wherein the service fragment includes service type information indicating a type of the broadcast service, and

wherein the type of the broadcast service includes a Linear Service for providing content in real time or an App-based Service based on an application.

11. A method of receiving a broadcast signal, the method comprising:

receiving content data and service guide information including access information of a broadcast service,

wherein the service guide information include a service fragment having information about the broadcast service and a content fragment having information about content data of the broadcast service,

wherein the content fragment further includes a content-level PrivateExt element having component information of the content data,

wherein the component information includes information for a component in the broadcast service, and

wherein the component is one of a video component, an audio component, and a closed caption component (CC); and

decoding the content data and the service guide information.

12. The method of claim 11, wherein the service fragment includes service type information indicating a type of the broadcast service, and

wherein the type of the broadcast service includes a Linear Service for providing content in real time or an App-based Service based on an application.
