Abstract: A method for processing a broadcast service at a Primary Device (PD), and which includes performing a discovery process with a Companion Device (CD) application in a CD by receiving a discovery request from the CD and providing an endpoint for a WebSocket server of the PD; establishing a connection between the WebSocket server and the CD application based on the endpoint; in response to receiving a query for a current service from the CD, transmitting a response for the current service to the CD application based on the connection; receiving a broadcast signal having signaling information including flag information to obtain emergency data in the broadcast signal; and time de-interleaving Forward Error Correction (FEC) blocks including the emergency data based on a Time Interleaving (TI) block, wherein the FEC blocks are de-interleaved based on position for one or more virtual FEC blocks and the FEC blocks. In addition, the signaling information further includes information for a maximum number for the FEC blocks. The method also includes transmitting a notification message including the emergency data to the CD.

Abstract: A method of processing a broadcast signal in a broadcast receiver includes receiving the broadcast signal including service data of a service, first signaling information for fast channel scans and service acquisition, and second signaling information providing information for discovery and acquisition of the service data. Further, the first signaling information includes bootstrap information for the second signaling information, identification information for identifying the service, category information for indicating a category of the service and capability information specifying a capability required to decode the service data. In addition, the second signaling information is carried in a Layered Coding Transport (LCT) channel that is identified by a Transport Session Identifier (TSI), and the bootstrap information includes address and port information for access of the second signaling information. The method also includes acquiring the service data based on at least the first signaling information or the second signaling information; and decoding the service data.

Abstract: A method for transmitting a V2X message by means of a V2X communication device is disclosed. A V2X communication method can comprise the steps of: receiving a platooning information message from an external V2X communication device; determining, on the basis of information comprised in the platooning information message, whether or not the concatenation with a platooning group is to be formed; if it is determined that the concatenation is to be formed, transmitting a concatenation request message for requesting the concatenation to the external V2X device; receiving from the external V2X device a concatenation response message which is a response message to the concatenation request message; and forming the concatenation with the platooning group. The platooning information message can comprise information relating to a platooning group to which a vehicle having an external V2X communication device belongs.
