Abstract: A method for communicating with a companion device (CD) in a primary device (PD) includes receiving a broadcast signal from a broadcast station; generating a multicast advertisement message based on a simple service discovery protocol (SSDP) when the PD joins a network and sending the multicast advertisement message to a pre-defined address. Further, the multicast advertisement message includes duration information for which the multicast advertisement message is valid, further the duration information is signaled in a cache-control header. The multicast advertisement message further includes identifier information which uniquely identifies the PD, further the identifier information is signaled in a USN header, and the multicast advertisement message further includes device type information, further the device type information is signaled in a NT header.
