Claim Text:
1. A method for controlling transmission of video to a wireless display device, the method comprising: controlling a video encoding rate for encoding video at a wireless transmission device based on a current data transmission rate capacity of a wireless channel, the current data transmission rate capacity being based on transmission-side measurement of channel availability, physical data rate, and packet error rate; and transmitting encoded video on the wireless channel at a data transmission rate not to exceed the current data transmission rate capacity, in response to the transmission-side measurement indicating the data transmission rate being less than the current data transmission rate capacity, increasing the data transmission rate with wherein higher-resolution video encoding is used for higher data transmission rate capacities, and in response to the transmission-side measurement indicating the data transmission rate being higher than the current data transmission rate capacity reducing the data transmission rate with lower-resolution video encoding is used for lower data transmission rate capacities, determining whether the display device is able to receive encoded video at different encoding rates; and when the display device is not able to receive encoded video at different encoding rates, the method includes:
