Abstract: Embodiments of the present disclosure provide a method, a device and a system for evaluating a user experience value of video quality. The method is: acquiring an uplink packet of a user equipment for requesting to watch an OTT video, where the uplink packet is transmitted by the user equipment to a video server storing the OTT video and carries request information of the user equipment on the OTT video; acquiring a downlink packet corresponding to the uplink packet, where the downlink packet is transmitted by the video server to the user equipment and carries the OTT video, and the OTT video is transmitted by the video server according to the request information in the uplink packet; buffering the downlink packet; and in response to determining that the buffered downlink packet satisfies a resolving condition, resolving the OTT video in the buffered downlink packet to generate a user experience value.

Abstract translation: 本公开的实施例提供了用于评估视频质量的用户体验值的方法，设备和系统。 该方法是：获取请求观看OTT视频的用户设备的上行分组，其中上行分组由用户设备发送到存储OTT视频的视频服务器，并在OTT视频上携带用户设备的请求信息 ; 获取对应于上行链路分组的下行分组，其中下行分组由视频服务器发送给用户设备并携带OTT视频，OTT视频由视频服务器根据上行分组中的请求信息发送; 缓冲下行数据包; 并且响应于确定所缓冲的下行链路分组满足解析条件，解析所缓冲的下行链路分组中的OTT视频以产生用户体验值。

Abstract: The present invention provides a method and an apparatus for determining video quality, and a method and an apparatus for locating a network fault. The method for determining video quality includes: obtaining a network key performance indicator KPI parameter on a first network device of a plurality of network devices, where the network KPI parameter includes a first round trip time RTT between a head-end device and the first network device; determining a Transmission Control Protocol TCP throughput of the first network device based on the network KPI parameter on the first network device; and determining video quality on the first network device based on the TCP throughput and a played video amount of the first network device. The present invention can accurately determine quality of a video transmitted by using the TCP protocol and accurately locate the network fault.

Abstract: The present invention discloses a method, an apparatus, and a system for implementing video quality assessment. When video quality is assessed, a proportion of a damaged data caused by packet loss in a video frame in which the damaged data is located is considered, and other factors are also considered, such as a position of the damaged data in the video frame and impact of a scene in which the video frame is located on the video frame or a video frame located after the video frame. Therefore, accuracy of quality assessment is higher.

Abstract: A video service quality assessment method and apparatus are provided to resolve a prior-art problem of relatively low accuracy of an assessment result. A monitoring device obtains an identifier of a to-be-monitored channel, an identifier of to-be-monitored user equipment, and configuration information of a video service transmission system; obtains a multicast video stream of the to-be-monitored channel based on the identifier of the to-be-monitored channel; obtains a retransmitted video stream based on the identifier of the to-be-monitored channel, the identifier of the to-be-monitored user equipment, and the configuration information of the video service transmission system; determines a to-be-assessed video stream based on the multicast video stream and the retransmitted video stream; and parses the to-be-assessed video stream, and obtains an assessment result based on a parsing result and the configuration information of the video service transmission system.
