Abstract
An apparatus and technique are disclosed for controlling the resource usage of a processor during a video conference by dynamically varying the rate at which video images are compressed so as to maintain a target threshold of processor resource usage. A control program module interfaces with the video encoder of a video conferencing system and first checks that the current processor resource utilization is below a specified target threshold prior to compressing a video image from a stream of captured video data. If the processor resource utilization is below the target threshold, the video image is compressed. Otherwise, the image is skipped to conserve processor resources. The technique allows video conferencing products to dynamically adjust the rate of video frame compression based on available processor resources so as to maximize the user's video conferencing experiencing while minimizing the negative impact on other applications executing on the system.
