Abstract
Provided is a broadcast receiving device receiving a broadcast service interoperating with a companion device. The broadcast receiving device includes: an IP communication unit configured to establish a pairing session with the companion device; a broadcast communication unit configured to receive an emergency alert message including an emergency alert alerting a disaster situation on the basis of the broadcast service; and a control unit configured to transmit information on the emergency alert message to the companion device.
Claims17
A primary device (PD) communicating with a companion device (CD), the primary device comprising:
- an IP communication unit to receive a discovery request from the CD, transmit a discovery response to the CD, receive a description request from the CD, and transmit a description response to the CD, the description response being used for connecting the CD with the PD;
- a broadcast reception unit to receive a physical layer frame comprised of a preamble and one or more pipes from a broadcast station, the preamble carrying signaling data providing fundamental signaling information for the physical layer frame, the signaling data including flag information, the physical layer frame including at least one emergency alert message (EAM) based on the flag information;
- and
- a control unit to transmit the at least one EAM received from the broadcast station to the CD.
A method for communicating with a companion device (CD) by a primary device (PD) receiving a broadcast service, the method comprising:
- receiving a discovery request from the CD;
- transmitting a discovery response to the CD;
- receiving a description request from the CD;
- transmitting a description response to the CD, the description response being used for connecting the CD with the PD;
- receiving a physical layer frame comprised of a preamble and one or more pipes from a broadcast station, the preamble carrying signaling data providing fundamental signaling information for the physical layer frame, the signaling data including flag information, the physical layer frame including at least one emergency alert message (EAM) based on the flag information;
- and
- transmitting the at least one EAM received from the broadcast station to the CD.
