Abstract

The present invention proposes a method for transmitting a broadcast signal. The method for transmitting a broadcast signal according to the present invention proposes a system capable of supporting next-generation broadcast service in an environment supporting a next-generation hybrid broadcast which uses a terrestrial broadcasting network and an internet network. Also, the present invention proposes an efficient signaling method which can encompass both the terrestrial broadcasting network and the internet network in an environment supporting next0-generation hybrid broadcast.

First claim

1 - 16 . (canceled)

17 . A method of processing service data, comprising:
generating service components of a broadcast service; generating first signaling data and second signaling data, wherein the first signaling data includes information for indicating the position of the second signaling data and the second signaling data signals the broadcast service; processing the service components and the second signaling data into transport packets, wherein the first signaling data includes destination IP address information, destination port number and source IP address information through which the second signaling data is delivered; transforming the first signaling data and the processed packets into a broadcast signal; and transmitting the transformed broadcast signal.

18 . The method according to claim 17 ,
wherein the first signaling data includes service identification information identifying a service and version information indicating changes in the first signaling data related to the service.

19 . The method according to claim 17 ,
wherein the second signaling data includes access information about the service components of the broadcast service.

20 . The method according to claim 17 ,
wherein the second signaling data further includes service description information.

21 . The method according to claim 17 ,
wherein the second signaling data includes ROUTE session information for indicating ROUTE session in which the service components of the broadcast service are transmitted.

22 . The method according to claim 21 ,
wherein the ROUTE session information includes destination IP address information, destination port number and source IP address information of the ROUTE session.

23 . An apparatus for processing service data, comprising:
a first module for generating service components of a broadcast service, wherein the first module generates first signaling data and second signaling data, wherein the first signaling data includes information for indicating the position of the second signaling data and the second signaling data signals the broadcast service; a second module for processing the service components and the second signaling data into transport packets, wherein the first signaling data includes destination IP address information, destination port number and source IP address information through which the second signaling data is delivered; a third module for transforming the first signaling data and the processed packets into a broadcast signal; and a fourth module for transmitting the transformed broadcast signal.

24 . The apparatus according to claim 23 , wherein the first signaling data includes service identification information identifying a service and version information indicating changes in the first signaling data related to the service.

25 . The apparatus according to claim 23 , wherein the second signaling data includes access information about the service components of the broadcast service.

26 . The apparatus according to claim 23 , wherein the second signaling data further includes service description information.

27 . The apparatus according to claim 23 , wherein the second signaling data includes ROUTE session information for indicating ROUTE session in which the service components of the broadcast service are transmitted.

28 . The apparatus according to claim 27 , wherein the ROUTE session information includes destination IP address information, destination port number and source IP address information of the ROUTE session.
