Patent ID: 8675682

Claim:
A wireless communication device comprising: a wire communication circuit configured to receive via a wire transmission line from a wire transmitter device, a packet including at least one of a video output format of video data and an audio output format of audio data; a controller configured to generate a wireless packet based on the packet received by the wire communication circuit; and a wireless communication circuit configured to wirelessly transmit the wireless packet generated by the controller to a further wireless communication device with which the wireless communication device establishes a wireless connection, wherein, when one of a current video output format and a current audio output format included in the packet received by the wire communication circuit is different from corresponding one of a prior video output format and a prior audio output format included in a packet received prior to a receiving timing of the received packet, the controller generates a wireless packet including corresponding one of the current video output format and the current audio output format, and wherein, when the video output format and the audio output format included in the packet received by the wire communication circuit are the same as the prior video output format and the prior audio output format, respectively, the controller does not generate any wireless packet; wherein, upon receiving a second message signal including a CEC (Consumer Electronics Control) message compliant with an HDMI (High-Definition Multimedia Interface) standard from the wire transmission line, the controller divides the CEC message into a plurality of groups and wirelessly transmits the groups.
