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

A broadcast signal transmission device comprising:

• a first encoder configured to encode service data of a service and service layer signaling information that are delivered over a Real-Time Object Delivery over Unidirectional Transport (ROUTE) session,
• wherein the service layer signaling information includes transport session information containing transport session identifier (TSI) information for the service data and wherein a value of TSI information for the service layer signaling information is zero;
• a second encoder configured to encode signaling information for one or more services including the service,
• wherein the signaling information includes one or more service element entries corresponding to the one or more services,
• wherein a service element entry corresponding to the service includes service information related to the service,
• wherein the service information includes service identification information for identifying the service, first version information for indicating a change of the service information, short name information of the service and access information of the ROUTE session, and
• wherein the access information includes destination address information and destination port information;
• and
• a transmitter configured to transmit a broadcast signal having the encoded service data, the encoded service layer signaling information and the encoded signaling information.

A broadcast signal reception method comprising:

• receiving a broadcast signal having service data of a service, service layer signaling information and signaling information for one or more services including the service,
• wherein the service data and the service layer signaling information are delivered over a Real-Time Object Delivery over Unidirectional Transport (ROUTE) session,
• wherein the signaling information includes one or more service element entries corresponding to the one or more services,
• wherein a service element entry corresponding to the service includes service information related to the service,
• wherein the service information includes service identification information for identifying the service, first version information for indicating a change of the service information, short name information of the service and access information of the ROUTE session,
• wherein the access information includes destination address information and destination port information,
• wherein the service layer signaling information includes transport session information containing transport session identifier (TSI) information for the service data, and
• wherein a value of TSI information for the service layer signaling information is zero;
• and
• processing the service data based on the signaling information and the service layer signaling information.
