Patent ID: 7779443

Claim:
A wireless communication system using a wireless channel, comprising: a first controller to determine a wireless communication state based on the checked maximum transmission throughput and to control the encoder or the wireless transmitter to change the data bitrate or the actual transmission rate, respectively, according to the determination of the wireless communication state; a transmitting device to change either a data bitrate of a video signal or an actual transmission rate of the video signal according to a determination of a maximum transmission throughput of the wireless channel, and to transmit the video signal over the wireless channel according to the change in the data bitrate of the video signal or the actual transmission rate of the video signal; and a receiving device to receive, temporarily store, and decode the video signal transmitted over the wireless channel, wherein the transmitting device transmits the video signal such that the receiving device receives more video signal data than is decoded by the receiving device when the maximum transmission throughput exceeds a predetermined threshold.
