Abstract:
1. A method performed to control a transmit rate of a wireless display device, the method comprising: determining a current data transmission rate capacity of a wireless channel; controlling a data transmission rate of a wireless transmission device based on the current data transmission rate capacity, and wherein determining the current data transmission rate capacity comprises estimating the current data transmission rate capacity using the following equation: where: WiDiChanCapacity is a current data transmission rate capacity of the channel; i is a physical data rate; MCSRate is a modulation and coding rate representing a physical layer link speed based on a protocol being used; PER is a packet error rate per each physical data rate, that is, a ratio of number of failed packets and number of total transmitted packets; NumPacket is a number of packets transmitted with each rate; XXXTpt is a maximum throughput of the channel based on a “XXX” protocol; channelbusy is a time that the channel is occupied by any other co-existing radio interference; and Totaltime is a time set aside to check a channel busy time.
