Abstract

A method for transmitting a broadcast signal is disclosed. The broadcast signal transmitting method proposes a system for supporting a next-generation broadcast service in an environment for supporting next-generation hybrid broadcast using a terrestrial broadcast network and the Internet network. In addition, the method proposes an efficient signaling method for supporting both the terrestrial broadcast network and the Internet network in an environment for supporting next-generation hybrid broadcast.

Claims

1-14. -14. (canceled)

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

generating service data of a broadcast service, first signaling information for signaling the service data, and second signaling information comprising positional information of a packet for transmitting the first signaling information,

wherein the first signaling information comprises at least one of ROUTE (Real-Time Object Delivery over Unidirectional Transport) protocol signaling information carried within a ROUTE session and MMT (MPEG Media Transport) protocol signaling information carried within a MMTP (MMT Protocol) session;

generating a broadcast signal including the service data, the first signaling information, and the second signaling information; and

transmitting the broadcast signal.

16. The method according to claim 15, wherein the second signaling information comprises information indicating whether the first signaling information is delivered by a ROUTE protocol or a MMT protocol.

17. The method according to claim 16, wherein the ROUTE protocol signaling information comprises:

service description information for ROUTE protocol for describing attributes of the broadcast service,

S-TSID (Service-based Transport Session Instance Description) comprising information for at least one ROUTE session transmitting the broadcast service and at least one LCT (Layered Coding Transport) session transmitting components of the broadcast service, and

MPD (Media Presentation Description) for ROUTE protocol comprising information about media presentation corresponding to the broadcast service.

18. The method according to claim 16, wherein the MMT protocol signaling information comprises:

service description information for MMT protocol for describing attributes of the broadcast service,

a MP (MMT Package) table for describing transport sessions in which components of the broadcast services transported by MMT protocol are delivered, and

MPD for MMT protocol comprising information about media presentation corresponding to components delivered over broadband.

19. The method according to claim 17, wherein:

the S-TSID includes RS (ROUTE Session) information describing the at least one ROUTE session;

the RS information includes broadcast stream identification information identifying a broadcast stream within which components of the broadcast service are carried and ROUTE identification information identifying the at least one ROUTE session; and

the ROUTE identification information includes source IP address information of a packet carrying the broadcast service, destination IP address information of a packet carrying the broadcast service, and destination port information of a packet carrying the broadcast service.

20. The method according to claim 19, wherein:

the RS information includes LS (LCT Session) information describing the at least one LCT session; and

the LS information includes information identifying the at least one LCT session, information indicating a maximum bandwidth of the at least one LCT session, start time information of the at least one LCT session and end time information of the at least one LCT session.

21. The method according to claim 18, wherein the service description information for MMT protocol comprises positional information for obtaining components of the broadcast service transmitted according to the ROUTE protocol.

22. A broadcast signal transmitting apparatus comprising:

a data generator for generating service data of a broadcast service, first signaling information for signaling the service data, and second signaling information comprising positional information of a packet for transmitting the first signaling information,
