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.

Abstract translation: 可提供视频质量管理（VQM）。 首先，可以由发送端点确定与视频流相对应的发送器度量。 所确定的发射机度量然后可以从发射端点发送并由接收机接收。 然后，接收机可以确定在接收机处接收的视频流的接收机度量。 然后可以由接收者确定质量得分。 质量得分可以基于接收到的发射机度量和确定的接收机度量。
