A video service quality assessment method, comprising: acquiring a video transaction from a network, wherein each video transaction comprises one piece of video data of a video; in response to a video transaction currently existing in a transaction queue in a transaction buffer pool being associated with the acquired video transaction, associating and synthesizing video data of the acquired video transaction and video data of the video transaction in the transaction queue to obtain associated and synthesized video data; and slicing (S 103) the associated and synthesized video data to obtain video slices, and making (S 103) a video service quality analysis based on the video slices; characterized in that making the video service quality analysis based on the video slices comprises: acquiring a user perception index value of each of the video slices, wherein the user perception index value is calculated based on a viewing experience index value and an interactive experience index value of each of the video slices; the interactive experience index value is calculated based on a video interactive response index value of each of the video slices, the video interactive response index value is used for reflecting a video switching interactive response speed; and the viewing experience index value is calculated based on a transmission quality index value and a video content quality index value of each of the video slices, the video content quality index value is calculated based on at least one of a video source code rate, a video resolution or a video frame rate, and the transmission quality index value is calculated based on a video blurred screen frequency value and a video blurred screen duration proportion or is calculated based on a video freezing frequency value and a video freezing duration proportion; and in response to a difference between user perception index values of two adjacent video slices being greater than a preset user perception index value difference threshold, a difference between video content quality index values of the two adjacent video slices being within a preset quality index value difference range, cells corresponding to the two adjacent video slices being different, and a difference between transmission quality index values of the two adjacent video slices being greater than a preset transmission difference threshold, recording cells corresponding to the two adjacent video slices as an abnormal handover cell pair. acquiring a video transaction from a network, wherein each video transaction comprises one piece of video data of a video; in response to a video transaction currently existing in a transaction queue in a transaction buffer pool being associated with the acquired video transaction, associating and synthesizing video data of the acquired video transaction and video data of the video transaction in the transaction queue to obtain associated and synthesized video data; and slicing (S 103) the associated and synthesized video data to obtain video slices, and making (S 103) a video service quality analysis based on the video slices; characterized in that making the video service quality analysis based on the video slices comprises: acquiring a user perception index value of each of the video slices, wherein the user perception index value is calculated based on a viewing experience index value and an interactive experience index value of each of the video slices; the interactive experience index value is calculated based on a video interactive response index value of each of the video slices, the video interactive response index value is used for reflecting a video switching interactive response speed; and the viewing experience index value is calculated based on a transmission quality index value and a video content quality index value of each of the video slices, the video content quality index value is calculated based on at least one of a video source code rate, a video resolution or a video frame rate, and the transmission quality index value is calculated based on a video blurred screen frequency value and a video blurred screen duration proportion or is calculated based on a video freezing frequency value and a video freezing duration proportion; and in response to a difference between user perception index values of two adjacent video slices being greater than a preset user perception index value difference threshold, a difference between video content quality index values of the two adjacent video slices being within a preset quality index value difference range, cells corresponding to the two adjacent video slices being different, and a difference between transmission quality index values of the two adjacent video slices being greater than a preset transmission difference threshold, recording cells corresponding to the two adjacent video slices as an abnormal handover cell pair.
