Patent ID: 7944908

Claim:
A method for setting an output bit rate for video data transmission in a Wireless Broadband (WiBro) system, said method comprising: calculating an uplink state value for a predetermined unit time to determine an uplink network state of the predetermined unit time; calculating an average of uplink state values for a predetermined number of unit times; and increasing a video encoding bit rate if the average of the uplink state values is larger than a predetermined first threshold, and decreasing the video encoding bit rate, if the average of the uplink state values is less than a predetermined second threshold; maintaining the video encoding hit rate and clearing a buffer prior to receiving new uplink state values if the average of the uplink state values is less than the first threshold and larger than the second threshold; and wherein the video encoding bit rate is determined as any one of a plurality of video encoding bit rates, and the plurality of video encoding bit rates are provided for use in (1) low congestion and non-mobility, (2) low congestion and mobility, and (3) high congestion and mobility.
