Broadcasting signal transmission apparatus, broadcasting signal receiving apparatus, broadcasting signal transmission method and broadcasting signal receiving method

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

• an encoder configured to encode service data, first signaling information for acquiring the service data, and second signaling information for acquiring the first signaling information, the second signaling information including IP address information of packets including the first signaling information;
• a builder configured to build a signal frame including the service data, the first signaling information, and the second signaling information;
• a transmitter configured to transmit the signal frame, the service data is transmitted based on a transport session,
• wherein the first signaling information is transmitted via a dedicated channel of the transport session and the first signaling information includes a first description including a delivery mode including a broadcast network for each service component in the service data, and
• the second signaling information is transmitted by being distinguished from the dedicated channel.

A method of transmitting a signal frame by an apparatus, the method comprising:

• receiving a signal frame including service data, first signaling information for acquiring the service data, second signaling information for acquiring the first signaling information, the second signaling information including IP address information of packets including the first signaling information;
• and
• decoding the service data,
• wherein the service data is carried based on a transport session,
• wherein the first signaling information is transmitted via a dedicated channel of the transport session and the first signaling information includes a first description including a delivery mode including a broadcast network for each service component in the service data, and
• wherein the second signaling information is transmitted by being distinguished from the dedicated channel.
