Abstract: In one embodiment, a method includes: determining a plurality of candidate paths for a plurality of media streams, where each of the candidate paths is characterized by a first set of performance attributes and each of the plurality of media streams is characterized by a set of stream parameters; jointly determining a respective path from among the plurality of candidate paths that satisfies the set of stream parameters for each of the plurality of the media streams; and coordinating transmission of the plurality of media streams via the jointly determined respective path for each of the plurality of media streams. According to some implementations, the method is performed by a device with one or more processors and non-transitory memory.

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。
