Abstract

A method for transmitting signaling information in a digital broadcasting system is provided. The method includes generating the signaling information for reception of a broadcast service, and transmitting the signaling information using at least one of a first transmission scheme and a second transmission scheme, which are different from each other in access time to a broadcast channel.

Claims

1. A method for transmitting signaling information in a digital broadcasting system, the method comprising:

generating signaling information for reception of a broadcast service; and

transmitting the signaling information using at least one of a first transmission scheme and a second transmission scheme, which are different from each other in access time to a broadcast channel.

2. The method of claim 1, wherein the signaling information includes first signaling information used for reception of the broadcast service, the first transmission scheme is faster than the second transmission scheme in terms of the access time, and the first signaling information is transmitted using the first transmission scheme.

3. The method of claim 2, wherein the signaling information includes second signaling information including at least one of remaining signaling information except for the first signaling information, and the second signaling information is transmitted using at least one of the first transmission scheme and the second transmission scheme.

4. The method of claim 2, wherein the first signaling information includes at least one of a package access (PA) message, a moving picture experts group (MPEG) media transport (MMT) composition information (MCI) message and network information in a MMT system.

5. The method of claim 4, wherein the first transmission scheme uses a generic stream encapsulation (GSE) scheme in a digital video broadcasting (DVB) system, and the second transmission scheme uses an MMT scheme.

6. A transmission apparatus for transmitting signaling information in a digital broadcasting system, the transmission apparatus comprising:

a transmission unit configured to transmit a frame including signaling information; and

a controller configured to control generating of the signaling information for reception of a broadcast service, and transmitting the signaling information using at least one of a first transmission scheme and a second transmission scheme, which are different from each other in access time to a broadcast channel.

7. The transmission apparatus of claim 6, wherein the signaling information includes first signaling information used for reception of the broadcast service, the first transmission scheme is faster than the second transmission scheme in terms of the access time, and the first signaling information is transmitted using the first transmission scheme.

8. The transmission apparatus of claim 7, wherein the signaling information includes second signaling information including at least one of remaining signaling information except for the first signaling information, and the second signaling information is transmitted using at least one of the first transmission scheme and the second transmission scheme.

9. The transmission apparatus of claim 7, wherein the first signaling information includes at least one of a package access (PA) message, a moving picture experts group (MPEG) media transport (MMT) composition information (MCI) message and network information in an MMT system.

10. The transmission apparatus of claim 9, wherein the first transmission scheme uses a generic stream encapsulation (GSE) scheme in a digital video broadcasting (DVB) system, and the second transmission scheme uses an MMT scheme.

11. A method for receiving signaling information in a digital broadcasting system, the method comprising:

receiving a frame including signaling information that is transmitted using at least one of a first transmission scheme and a second transmission scheme, which are different from each other in access time to a broadcast channel; and

acquiring the signaling information using at least one scheme among the first transmission scheme and the second transmission scheme.

12. The method of claim 11, wherein the signaling information includes first signaling information used for reception of the broadcast service, the first transmission scheme is faster than the second transmission scheme in terms of the access time, and the first signaling information is received using the first transmission scheme.

13. The method of claim 12, wherein the signaling information includes second signaling information including at least one of remaining signaling information except for the first signaling information, and the second signaling information is received using at least one of the first transmission scheme and the second transmission scheme.

14. The method of claim 12, wherein the first signaling information includes at least one of a package access (PA) message, a moving picture experts group (MPEG) media transport (MMT) composition information (MCI) message and network information in an MMT system.

15. The method of claim 14, wherein the first transmission scheme uses a generic stream encapsulation (GSE) scheme in a digital video broadcasting (DVB) system, and the second transmission scheme uses an MMT scheme;

wherein the method further comprises reconstructing the received signaling information according to the MMT scheme, if the second transmission scheme is used.

16. A reception apparatus for receiving signaling information in a digital broadcasting system, the reception apparatus comprising:
