Broadcast signal transmission device, broadcast signal receiving device, broadcast signal transmission method and broadcast signal receiving method

A method for transmitting a broadcast signal by a broadcast transmission device, the method comprising:

• generating a content component for a broadcast service, service signaling information including object flow information for an object flow which carries the content component and signaling information for listing broadcast services,
• the object flow information includes format information representing a payload format of an object, and
• the service signaling information is carried by transport packets;
• and
• transmitting the broadcast signal including the signaling information, the service signaling information and the content component.

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

• a receiver to receive the broadcast signal including a content component for a broadcast service, service signaling information including object flow information for an object flow which carries the content component and signaling information for listing broadcast services,
• the object flow information includes format information representing a payload format of an object, and
• the service signaling information is carried by transport packets;
• and
• a controller to:
• parse the signaling information, service signaling information, and
• obtain the content component based on the service signaling information.
