Abstract

A companion device is provided for interoperating with a broadcast service that a broadcast reception device receives. The companion device comprises a communication unit and a control unit. The communication unit transmits a discovery request to the broadcast reception device, receives a discovery response from the broadcast reception device, transmits a description request to the broadcast reception device, and receives a description response from the broadcast reception device. The description response is used for connecting the companion device with the broadcast reception device. The control unit transmits a request for the broadcast service and receives a response from the broadcast reception device. The response includes device capability information signaling a capability of a device necessary for presenting a media component included in the broadcast service. The control unit receives the media component when a capability of the companion device satisfies the device capability that the device capability information includes.
