Abstract:
1. A sink-side wireless communication device being wiredly connectable with a sink-side wired communication device and wirelessly communicable with a source-side wireless communication device that is wiredly connectable with a source-side wired communication device, the sink-side wireless communication device comprising: a memory; a cable port for receiving a cable from an external device; an acquisition module configured to acquire display device identification information from the external device, the display device identification information being compatible with a communication method using the cable; a determination module configured to determine whether the external device is the source-side wireless communication device or the sink side wired communication device, based on the acquired display device identification information; an authentication module configured to perform, when the determination module determines that the external device is the source-side wireless communication device, an authentication process with the source-side wireless communication device and to store authentication information acquired though the authentication process into the memory; a wired communication module configured to perform, when the determination module determines that the external device is the sink-side wired communication device, a wired communication with the sink-side wired communication device; and a wireless communication module configured to perform, when the sink-side wired communication device is wiredly connected to the cable port, a wireless communication with the source-side wireless communication device, based on the authentication information stored in the memory.
