Patent ID: 8036194

Claim:
A communication device that is connected wirelessly as a sink-side device to a source-side communication device, the communication device comprising: a wired communication module configured to transmit a video signal to a sink device and exchange a data signal with the sink device via wired communication; a first wireless communication module configured to receive a video signal from the source-side communication device that is connected via a wire to a source device through a first wireless communication system capable of at least transmission and receipt of a video signal; a second wireless communication module configured to exchange a data signal with the source-side communication device through a second wireless communication system; and a communication controller configured to control communication by the wired communication module, the first wireless communication module, and the second wireless communication module, the communication controller configured to perform processing related to a physical address used in a communication system of the wired communication module with the source-side communication device after the first wireless communication module establishes a wireless link, relay information as to data communication capability exchanged between the sink device and the source device through the wired communication module and the first wireless communication module; exchange information as to data communication capability with the source-side communication device through the first wireless communication module, and when the sink device, the source device, and the source-side communication device are capable of data communication, set data communication as possible with a communication module assigned a physical address for wireless communication performed through the second wireless communication module.
