Abstract

A method for transmitting and receiving a broadcast signal is disclosed. The method for transmitting a broadcast signal, according to an embodiment of the present invention, comprises the steps of: performing delivery layer processing on broadcast service data and signaling information about the broadcast service data; performing UDP/IP encapsulating on the broadcast service data and the signaling information about the broadcast service data; and performing physical layer processing on the broadcast service data and the signaling information about the broadcast service data.

Claims

1. A method for transmitting a broadcast signal, the method comprising:

generating service layer signaling (SLS) information comprising information for discovery and acquisition of at least one content component, wherein the SLS information and the at least one content component are carried based on a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol;

generating service list table (SLT) information comprising bootstrap information for acquiring the SLS information;

User Datagram Protocol (UDP)/Internet Protocol (IP) encapsulating the at least one content component, the SLS information, and the SLT information; and

transmitting a physical layer frame comprising the at least one content component, the SLS information, and the SLT information,

wherein when the SLS information and the at least one content component are carried based on the ROUTE protocol, the SLS information comprises a Service-based Transport Session Instance Description (S-TSID) fragment,

wherein the S-TSID fragment comprises an RS element comprising information on a ROUTE session in which the at least one content component is carried and an LS element comprising information on at least one LCT channel that carries the at least one content component, further the LS element comprises a source flow element comprising information about a source flow,

wherein the source flow element comprises a ContentInfo element for providing information for the at least one content component carried in at least one LCT channel, and

wherein the ContentInfo element comprises at least one of a first element comprising information about a DASH representation carried in at least one LCT channel or a second element for representing an identifier of an individual Advanced Emergency Alert (AEA) message to which information carried in at least one LCT channel is associated.

2. The method of claim 1, wherein the first element comprises representation ID information indicating representation ID of the DASH representation.

3. The method of claim 2, wherein the first element further comprises language information indicating a language of the DASH representation and type information indicating a type of the DASH representation.

4. The method of claim 1, wherein the second element comprises AEA ID information indicating an ID of the AEA message.

5. The method of claim 1, wherein the SLS information further comprises a Media Presentation Description (MPD) fragment, and

wherein the MPD fragment comprises content ID information for identifying a content of the at least one content component, and the type of the content ID information comprises at least one of an EIDR type using an EIDR ID registered in the EIDR registry as a content ID, an Ad-ID type using an Ad-ID registered in Ad-ID system as a content ID, or a user private ID type using an ID registered in a user private system as a content ID.

6. A broadcast signal transmitter, comprising:

a signaling generator configured to generate service layer signaling (SLS) information and service list table (SLT) information,

wherein the SLS information comprises information for discovery and acquisition of at least one content component, and the SLT information comprises bootstrap information for acquisition of the SLS information,

wherein the SLS information and the at least one content component are carried based on a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol;

a UDP/IP encapsulator configured to encapsulate User Datagram Protocol (UDP)/Internet Protocol (IP) on the at least one content component, the SLS information, and the SLT information; and

a physical layer processor configured to transmit a physical layer frame comprising the at least one content component, the SLS information, and the SLT information,

wherein when the SLS information and the at least one content component are carried based on the ROUTE protocol, the SLS information comprises a Service-based Transport Session Instance Description (S-TSID) fragment,

wherein the S-TSID fragment comprises an RS element comprising information on a ROUTE session in which the at least one content component is carried and an LS element comprising information on at least one LCT channel that carries the at least one content component, further the LS element comprises a source flow element comprising information about a source flow,

wherein the source flow element comprises a ContentInfo element for providing information for the at least one content component carried in at least one LCT channel, and

wherein the ContentInfo element comprises at least one of a first element comprising information about a DASH representation carried in at least one LCT channel or a second element for representing an identifier of an individual Advanced Emergency Alert (AEA) message to which information carried in at least one LCT channel is associated.

7. The broadcast signal transmitter of claim 6, wherein the first element comprises representation ID information indicating representation ID of the DASH representation.

8. The broadcast signal transmitter of claim 7, wherein the first element further comprises language information indicating a language of the DASH representation and type information indicating a type of the DASH representation.

9. The broadcast signal transmitter of claim 6, wherein the second element comprises AEA ID information indicating an ID of the AEA message.

10. The broadcast signal transmitter of claim 6, wherein the SLS information further comprises a Media Presentation Description (MPD) fragment, and

wherein the MPD fragment comprises content ID information for identifying a content of the at least one content component, and the type of the content ID information comprises at least one of an EIDR type using an EIDR ID registered in the EIDR registry as a content ID, an Ad-ID type using an Ad-ID registered in Ad-ID system as a content ID, or a user private ID type using an ID registered in a user private system as a content ID.
