Abstract

A method for processing a broadcast signal includes encoding broadcast data for at least one broadcast service; encoding first level signaling information including attribute information regarding the at least one broadcast service; encoding second level signaling information including information for listing the at least one broadcast service; and generating a broadcast signal including the encoded broadcast data, the first level signaling information, and the second level signaling information.

Claims

1. A method for processing a broadcast signal comprising:

encoding broadcast data for at least one broadcast service;

encoding first level signaling information including attribute information regarding the at least one broadcast service;

encoding second level signaling information including information for listing the at least one broadcast service; and

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

wherein the first level signaling information includes first protocol signaling information and second protocol signaling information; and

the second level signaling information includes service level signaling protocol information configured to identify whether the first protocol signaling information or the second protocol signaling information is applied to each of the at least one broadcast service.

2. The method according to claim 1, wherein:

the first protocol signaling information corresponds to service layer signaling information to which ROUTE (Real-Time Object Delivery over Unidirectional Transport) protocol is applied; and

the second protocol signaling information corresponds to service layer signaling information to which MMT (MPEG Media Transport) protocol is applied.

3. The method according to claim 2, wherein the second level signaling information further includes:

source IP (Internet Protocol) address information to identify a source IP (Internet Protocol) address of a packet needed to transmit either the first protocol signaling information or the second protocol signaling information; and

destination IP address information to identify a destination IP address.

4. The method according to claim 3, wherein:

the at least one broadcast service includes a first broadcast service including at least one realtime component and at least one non-realtime component;

the first protocol signaling information includes ROUTE component information for signaling information needed to obtain the at least one non-realtime component; and

the second protocol signaling information includes MMT component information for signaling information needed to obtain the at least one realtime component.

5. The method according to claim 4, wherein the second protocol signaling information includes position information for obtaining the ROUTE component information contained in the first protocol signaling information.

6. The method according to claim 4, wherein:

the second protocol signaling information includes a service layer signaling message,

wherein the service layer signaling message includes information for identifying a signaling element contained in the service layer signaling message.

7. The method according to claim 6, wherein the service layer signaling message further includes information for identifying the length of the signaling element.

8. An apparatus for processing a broadcast signal comprising:

a data encoder configured to encode broadcast data for at least one broadcast service;
