Abstract:

Video quality management (VQM) may be provided. First, transmitter metrics corresponding to a video stream may be determined by a transmitting endpoint. The determined transmitter metrics may then be transmitted from the transmitting end point and received by a receiver. The receiver may then determine receiver metrics for a video stream received at the receiver. A quality score may then be determined by the receiver. The quality score may be based on the received transmitter metrics and the determined receiver metrics.
