Abstract:
1. A device configured for Wi-Fi display, comprising: a Wi-Fi transmitter configured to transmit to a receiver in a wireless display (WiDi) system over a Wi-Fi channel that makes use of one or more of versions of IEEE 802.11; wherein the device is configured to query capacity of a wireless WiFi channel and to determine whether to change a current encoding bit rate based on a MaxRateThreshold which is an upperbound of a video bit rate and a MinRateThreshold which is a lower-bound of the video bit rate; wherein the video bit rate for encoding is adapted to gradually increase if the difference between channel capacity and current video bit rate is larger than a predetermined threshold value; and wherein the video bit rate for encoding is adapted to decrease to a value below channel capacity if the current and last capacity value are less than the current and last video bit rate.
