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.
