Abstract
A method and apparatus for real time adjustment of wireless transmission in a media device (e.g., webcam), as opposed to a server or computer. In one embodiment, the adjustment, or dynamic tuning, involves tracking available bandwidth of the radio signaling rate and varying one of the retry rate, compression and frame rate. Also, the adjustment can be made on the basis of forecasts based on past behavior. A tracking and control algorithm is used to modulate the video bit-rate from the camera with the dynamic bit-rate available in a WiFi link.
