Abstract

A method for generating and processing a broadcast signal according to an embodiment of the present invention includes: encoding broadcast data for one or more broadcast services; encoding first level signaling information including information describing properties of the one or more broadcast services; encoding second level signaling information including information for listing the one or more broadcast services; and generating a broadcast signal including the encoded broadcast data, the encoded first level signaling information and the encoded second level signaling information.

Claims

1. A method for generating and processing a broadcast signal, comprising:

encoding broadcast data for one or more broadcast services;

encoding first level signaling information including information describing properties of the one or more broadcast services;

encoding second level signaling information including information for listing the one or more broadcast services; and

generating a broadcast signal including the encoded broadcast data, the encoded first level signaling information and the encoded second level signaling information,

wherein the second level signaling information includes URL information identifying a URL for acquiring ESG data or the first level signaling information and URL type information indicating whether the ESG data or the first level signaling information is provided through the URL identified by the URL information.

2. The method according to claim 1, wherein the second level signaling information further includes a broadcast network signaling information element including information necessary for a receiver to acquire the first level signaling information.

3. The method according to claim 2, wherein the second level signaling information further includes destination IP address information indicating a destination IP address of packets delivering the first level signaling information and port number information indicating a port number of the packets delivering the first level signaling information.

4. The method according to claim 3, wherein the second level signaling information further includes source IP address information indicating a source IP address of the packets delivering the first level signaling information.

5. The method according to claim 4, wherein the second level signaling information further includes capability information including information about capabilities required for the receiver to decode and effectively present one or more pieces of content included in the one or more broadcast services.

6. The method according to claim 5, wherein the second level signaling information further includes simple service information indicating whether accessing a broadband network is necessary to effectively present the one or more broadcast services.

7. The method according to claim 6, wherein the second level signaling information further includes provider identifier information identifying a broadcaster providing the one or more broadcast services.

8. An apparatus for generating and processing a broadcast signal, comprising:

a data encoder for encoding broadcast data for one or more broadcast services;

a first level signaling encoder for encoding first level signaling information including information describing properties of the one or more broadcast services;

a second level signaling encoder for encoding second level signaling information including information for listing the one or more broadcast services; and

a broadcast signal generator for generating a broadcast signal including the encoded broadcast data, the encoded first level signaling information and the encoded second level signaling information,

wherein the second level signaling information includes URL information identifying a URL for acquiring ESG data or the first level signaling information and URL type information indicating whether the ESG data or the first level signaling information is provided through the URL identified by the URL information.

9. The apparatus according to claim 8, wherein the second level signaling information further includes a broadcast network signaling information element including information necessary for a receiver to acquire the first level signaling information.

10. The apparatus according to claim 9, wherein the second level signaling information further includes destination IP address information indicating a destination IP address of packets delivering the first level signaling information and port number information indicating a port number of the packets delivering the first level signaling information.

11. The apparatus according to claim 10, wherein the second level signaling information further includes source IP address information indicating a source IP address of the packets delivering the first level signaling information.

12. The apparatus according to claim 11, wherein the second level signaling information further includes capability information including information about capabilities required for the receiver to decode and effectively present one or more pieces of content included in the one or more broadcast services.

13. The apparatus according to claim 12, wherein the second level signaling information further includes simple service information indicating whether accessing a broadband network is necessary to effectively present the one or more broadcast services.

14. The apparatus according to claim 13, wherein the second level signaling information further includes provider identifier information identifying a broadcaster providing the one or more broadcast services.
