Embodiment Construction
[0052] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
[0053] In the prior art, inspection personnel usually watch the video images collected by the sending end and the video images displayed by the receiving end, and the inspection personnel compare the observed video images to determine the quality of video communication. Determining the quality of video communication only based on the results watched by inspectors with naked eyes, the detection results are often subjective and cannot effectively reflect the current quality of video communication.
[0054] Based on the above considerations, the present invention provides a video communication quality detection method, which can be applied to electronic equipment. see figure 1 , is a scene diagram of video communication quality detection provided by an embodiment of the present invention, and the electron...

The embodiment of the invention provides a video communication quality detection method and device. In view of a target video frame in a video image displayed at a receiving end, the system time in the receiving end when the receiving end displays the target video frame is acquired as first system time, and the system time in a transmitting end when the transmitting end acquires the video frame corresponding to the target video frame is acquired as second system time; according to the system time difference between the transmitting end and the receiving end, the first system time and the second system time, the time delay of the target video frame is determined; and according to communication quality detection parameters, the video communication quality between the transmitting end and thereceiving end is determined, and the communication quality detection parameters comprise the time delay of the target video frame. Based on the above processing, the time delay of the video frame canbe accurately determined to detect the video communication quality instead of detecting the video communication quality only based on the result observed by naked eyes of a detector, and the effectiveness of the video communication quality detection result can be improved.
Description
technical field [0001] The invention relates to the field of network technology, in particular to a video communication quality detection method and device. Background technique [0002] With the rapid development of mobile Internet technologies, more and more users choose to use terminals (eg, mobile phones, tablets) to make video calls. Factors such as different network operators and large geographical spans of terminals will lead to network instability between terminals, thereby affecting the quality of video communication between terminals. By detecting the quality of video communication between terminals, problems existing in current video communication can be determined, and then the quality of video communication can be improved. [0003] In the prior art, inspection personnel usually watch the video images collected by the sending end and the video images displayed by the receiving end, and the inspection personnel compare the observed video images to determine the ...
