Abstract
(EN)
Provided in the present invention are a video quality evaluation method, device and remote radio head. A video quality evaluation device receives a video stream of a video to be evaluated, the video stream comprising a plurality of video frames, each video frame of the plurality of video frames being carried in at least one video packet; the video quality evaluation device receives indication information from a remote radio head, the indication information being used for indicating a mapping relationship between the frame type of each of the plurality of video frames and the video packet corresponding to the video frame; and the video quality evaluation device determines a video quality evaluation result of the video to be evaluated, according to the video stream of the video to be evaluated and the indication information thereof. The present invention can be used to accurately evaluate the quality of a video.
