Abstract

A method for receiving a broadcast signal, performed by an apparatus for receiving the broadcast signal includes receiving the broadcast signal, wherein the broadcast signal includes one or more link layer packets, wherein the one or more link layer packets includes broadcast data for a broadcast service, service level signaling information describing characteristics of the broadcast service, and low level signaling information including information which is used to build a basic service listing, wherein the low level signaling information further includes service level signaling protocol information for indicating a type of delivery protocol of the service level signaling information, wherein the type of the delivery protocol corresponds to a Moving Picture Experts Group (MPEG) media transport (MMT) protocol or a real-time object delivery over unidirectional transport (ROUTE) protocol, and wherein the low level signaling information further includes destination Internet Protocol (IP) address for the service level signaling information, destination User Datagram Protocol (UDP) port number for the service level signaling information, and source IP address for the service level signaling information, parsing the low level signaling information, and parsing the service level signaling information.

Claims

receiving the signal,

wherein the signal includes one or more link layer packets,

wherein the one or more link layer packets include data for a service, service layer signaling information describing characteristics of the service, and low level signaling information including information which is used to provide bootstrap discovery of the service layer signaling information,

wherein the low level signaling information further includes protocol information for representing a type of delivery protocol of the service layer signaling information,

wherein the type of the delivery protocol corresponds to a Moving Picture Experts Group (MPEG) media transport (MMT) protocol or a real-time object delivery over unidirectional transport (ROUTE) protocol, and

wherein the low level signaling information further includes destination Internet Protocol (IP) address for the service layer signaling information, and destination User Datagram Protocol (UDP) port number for the service layer signaling information;

parsing the low level signaling information; and

parsing the service layer signaling information.

2. The method according to claim 1,

wherein the parsing the service layer signaling information is based on the low level signaling information.

3. The method according to claim 1,

wherein the service layer signaling information includes application signaling element pertaining to a delivery of application-based enhancement component.

4. A receiver for receiving a signal, the receiver comprising:

a tuner configured to receive the signal,

wherein the signal includes one or more link layer packets,

wherein the one or more link layer packets include data for a service, service layer signaling information describing characteristics of the service, and low level signaling information including information which is used to provide bootstrap discovery of the service layer signaling information,
