Abstract
A method for real time video transmission over networks with varying bandwidth is described. Image quality is maintained even under degrading network performance conditions through the use of image scaling in conjunction with block based motion compensated video coding (MPEG2/4, H.264, et. Al.). The ability to quickly switch resolutions without decreasing reference frame correlation is shown enabling a fast switch to reduce the required bandwidth for stable image quality.
