Abstract

An apparatus for receiving a broadcast signal, includes a receiver configured to receive the broadcast signal including physical layer signaling data, signaling data, content data and service guide information, wherein the signaling data is included in a signal frame indicated by the physical layer signaling data, wherein the signaling data includes mapping information between a service and a PLP, and information supporting channel scanning and service acquisition, wherein the service guide information includes 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).

Claims

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

a receiver configured to receive the broadcast signal including physical layer signaling data, signaling data, content data and service guide information,

wherein the signaling data is included in a signal frame indicated by the physical layer signaling data,

wherein the signaling data includes mapping information between a broadcast service and a physical layer pipe (PLP), and information supporting channel scanning and service acquisition,

wherein the service guide information includes 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);

a signaling decoder configured to decode the physical layer signaling data, wherein the mapping information and the information supporting channel scanning and service acquisition are further decoded from the signal frame based on the decoded physical layer signaling data;

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

a display screen configured to display an image representing that an application-based (App-based) service is available for the broadcast service; and

a user input interface to detect a user input,

wherein when the user input selecting the displayed image representing the App-based service is detected, an application for the App-based service is displayed on the display screen.

2. The apparatus 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 the App-based service based on an application.

3. The apparatus 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 apparatus 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. A method of receiving a broadcast signal, the method comprising:

receiving the broadcast signal including physical layer signaling data, signaling data, content data and service guide information,

wherein the signaling data is included in a signal frame indicated by the physical layer signaling data,

wherein the signaling data includes mapping information between a broadcast service and a physical layer pipe (PLP), and information supporting channel scanning and service acquisition,

wherein the service guide information includes 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);

decoding the physical layer signaling data, wherein the mapping information and the information supporting channel scanning and service acquisition are further decoded from the signal frame based on the decoded physical layer signaling data;

decoding the content data and the service guide information;

displaying an image representing that an application-based (App-based) service is available for the broadcast service;

detecting a user input selecting the displayed image representing the App-based service; and

displaying an application for the App-based service on a display screen.

6. The method 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 the App-based service based on an application.

7. The method 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 method 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.
