Abstract

A broadcast reception method includes: receiving a broadcast signal including service data and signaling information for a service, wherein the signaling information includes first signaling information for acquisition of the service, wherein the signaling information includes second signaling information including bootstrap information for the service; acquiring the service data on the basis of the signaling information; and decoding the service data, wherein the signaling information includes electronic service guide (ESG) bootstrap information for ESG data.

Claims

1-14. -14. (canceled)

15. A broadcast signal reception method comprising:

receiving a broadcast signal including service data and signaling information for a service,

wherein the signaling information includes first signaling information for acquisition of the service,

wherein the signaling information includes second signaling information including bootstrapping information of the first signaling information for the service,

acquiring the service data based on the signaling information,

wherein the second signaling information includes category information indicating a category of the service,

wherein the category information indicates an Electronic Service Guide (ESG) service, and

wherein the second signaling information further includes ESG bootstrapping information for the ESG service.

16. The broadcast signal reception method of claim 15,

wherein the ESG service includes a Service Guide Delivery Unit (SGDU) including data for a service guide, and

wherein the SGDU is described in a Service Guide Delivery Descriptor (SGDD).

17. The broadcast signal reception method of claim 16,

wherein the broadcast signal includes a first session delivering an object in real time over a unidirectional transport,

wherein the first session includes one or more second sessions carrying content components that make up the service,

wherein the SGDD is delivered by using the second session of the first session, and

wherein the SGDU is delivered by using the one or more second sessions of the first session.

18. The broadcast signal reception method of claim 17,

wherein the ESG bootstrapping information includes at least one of source IP Address information indicating a source IP address of packets carrying the SGDD, destination IP address information indicating a destination IP address of packets carrying the SGDD, and destination port number information indicating a port number of the packets carrying the SGDD.

19. The broadcast signal reception method of claim 18,

wherein the ESG bootstrapping information includes at least one of transportStreamID information specifying a frequency of packets carrying the SGDD, partitionID information identifying a partition of the frequency of packets carrying the SGDD, PLP ID information indicating a Physical Layer Pipe (PLP) of packets carrying the SGDD, TSI information indicating a transport session of packets carrying the SGDD, and URL information indicating a location of packets carrying the SGDD.

20. The broadcast signal reception method of claim 18,

wherein the first signaling information includes fragmentation information indicating how a payload of a transport packet carrying the object is fragmented for delivery.

21. The broadcast signal reception method of claim 20,

wherein the payload of the transport packet carries one of a contiguous portion of the object whose fragmentation occurs at arbitrary byte boundaries, media data in a form of one or more complete samples, and entire data content of one or more boxes.

22. A broadcast signal reception apparatus comprising:

a tuner for receiving a broadcast signal including service data and signaling information for a service,

wherein the signaling information includes first signaling information for acquisition of the service,

wherein the signaling information includes second signaling information including bootstrapping information of the first signaling information for the service, a controller for acquiring the service data based on the signaling information,

wherein the second signaling information includes category information indicating a category of the service,

wherein the category information indicates an Electronic Service Guide (ESG) service, and

wherein the second signaling information further includes ESG bootstrapping information for the ESG service.

23. The broadcast signal reception apparatus of claim 22,

wherein the ESG service includes a Service Guide Delivery Unit (SGDU) including data for a service guide, and

wherein the SGDU is described in a Service Guide Delivery Descriptor (SGDD).

24. The broadcast signal reception apparatus of claim 23,

wherein the broadcast signal includes a first session delivering an object in real time over a unidirectional transport,

wherein the first session includes one or more second sessions carrying content components that make up the service,

wherein the SGDD is delivered by using the second session of the first session, and

wherein the SGDU is delivered by using the one or more second sessions of the first session.

25. The broadcast signal reception apparatus of claim 24,

wherein the ESG bootstrapping information includes at least one of source IP Address information, indicating a source IP address of packets carrying the SGDD, destination IP address information indicating a destination IP address of packets carrying the SGDD, and destination port number information indicating a port number of the packets carrying the SGDD.
