Abstract
Improved systems and methods of performing multimedia communications over multimedia communications networks, in which video data senders can maintain high video quality of experience (QoE) levels with increased reliability despite changes in available bandwidths of video data receivers. In the disclosed systems and methods, video encoding parameters employed by the video data senders, including at least the video frame size and/or the video frame rate, can be dynamically adapted to the available bandwidths of the video data receivers, taking into account possible effects of spatial scaling and/or temporal scaling of video frames on the resulting video QoE.
