Apparatus for transmitting broadcast signal, apparatus for receiving broadcast signal, method for transmitting broadcast signal and method for receiving broadcast signal

An apparatus for transmitting a broadcast signal, the apparatus comprising:

• a signaling encoder to generate service layer signaling information describing characteristics of a broadcast service and service list signaling information for listing one or more broadcast services,
• the service list signaling information includes information for obtaining the service layer signaling information,
• the service list signaling information further includes first capability information identifying capabilities needed to decode and present broadcast contents for the one or more broadcast services listed in the service list signaling information,
• the service list signaling information further includes service identifying information identifying the broadcast service, and
• the service list signaling information further includes second capability information identifying capabilities needed to decode and present broadcast contents for the broadcast service identified by the service identifying information;
• and
• a broadcast signal generator to transmit the broadcast signal including the service layer signaling information and the service list signaling information.

A method for receiving a broadcast signal by a broadcast receiver, the method comprising:

• receiving the broadcast signal including service layer signaling information describing characteristics of a broadcast service and service list signaling information for listing one or more broadcast services,
• the service list signaling information includes information for obtaining the service layer signaling information,
• the service list signaling information further includes first capability information identifying capabilities needed to decode and present broadcast contents for the one or more broadcast services listed in the service list signaling information,
• the service list signaling information further includes service identifying information identifying the broadcast service, and
• the service list signaling information further includes second capability information identifying capabilities needed to decode and present broadcast contents for the broadcast service identified by the service identifying information;
• and
• parsing the service list signaling information;
• and
• parsing the service layer signaling information.

An apparatus for receiving a broadcast signal, the apparatus comprising:

• a receiver to receive the broadcast signal including service layer signaling information describing characteristics of a broadcast service and service list signaling information for listing one or more broadcast services,
• the service list signaling information includes information for obtaining the service layer signaling information,
• the service list signaling information further includes first capability information identifying capabilities needed to decode and present broadcast contents for the one or more broadcast services listed in the service list signaling information,
• the service list signaling information further includes service identifying information identifying the broadcast service, and
• the service list signaling information further includes second capability information identifying capabilities needed to decode and present broadcast contents for the broadcast service identified by the service identifying information;
• and
• a parser to:
• parse the service list signaling information;
• and
• parse the service layer signaling information.
