The first wireless communication circuit executes receiving first image information by a first wireless communication method, and transmitting wireless connection destination information. The processor executes adding information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is coupled to a display device, and not adding the information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is not coupled to the display device. ## Claims ### Claim 1 A wireless communication device comprising: a first wireless communication circuit executing receiving first image information by a first wireless communication method, and wirelessly transmitting wireless connection destination information for communicatively coupling to the wireless communication device; a first terminal; and a processor executing adding information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is coupled to a display device, and not adding the information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is not coupled to the display device. ### Claim 2 (depends on 1) The wireless communication device according to claim 1, wherein the first wireless communication circuit maintains communication by the first wireless communication method when a hot-plug-detect signal from the first terminal changes from on to off while communication by the first wireless communication method is being executed. ### Claim 3 (depends on 1) The wireless communication device according to claim 1, further comprising: a second wireless communication circuit receiving second image information by a second wireless communication method that is different from the first wireless communication method; and a second terminal that is different from the first terminal, wherein the first wireless communication circuit decodes the first image information, the processor transmits the second image information to the display device via the second terminal when the second wireless communication circuit receives the second image information, and the display device decodes the second image information. ### Claim 4 (depends on 3) The wireless communication device according to claim 3, wherein the first terminal is an HDMI terminal, and the second terminal is a USB terminal. ### Claim 5 A method for controlling a wireless communication device comprising: wirelessly transmitting wireless connection destination information with information added thereto representing that communication is performed by a first wireless communication method, when a first terminal is coupled to a display device; and wirelessly transmitting the wireless connection destination information without the information added thereto representing that communication is performed by the first wireless communication method, when the first terminal is not coupled to the display device, wherein the wireless connection destination information enables communicative coupling to the wireless communication device. ### Claim 6 (depends on 5) The method for controlling the wireless communication device according to claim 5, further comprising: receiving first image information by the first wireless communication method; and outputting the first image information to the display device.
