Video data quality assessment method and apparatus

摘要

A video data quality assessment method and apparatus are disclosed. The video data quality assessment method includes: acquiring a compression distortion parameter of video data; acquiring a frame impairment distortion parameter/video data rebuffering parameter; and calculating a video quality parameter according to the compression distortion parameter and the frame impairment distortion parameter/video data rebuffering parameter, where the video quality parameter is a difference between the compression distortion parameter and the frame impairment distortion parameter/video data rebuffering parameter.

1. A video data quality assessment method, comprising:
acquiring a compression distortion parameter of video data according to packet header information of a video data packet; acquiring a frame impairment distortion parameter according to the packet header information of the video data packet; and calculating a video quality parameter according to the compression distortion parameter and the frame impairment distortion parameter, wherein the video quality parameter comprises a difference between the compression distortion parameter and the frame impairment distortion parameter, wherein acquiring the compression distortion parameter of the video data comprises:
acquiring a bit rate and a frame rate of a video stream; andcalculating the compression distortion parameter according to the bit rate and the frame rate of the video stream,wherein the compression distortion parameter increases to approach a maximum value as the bit rate increases, andwherein the compression distortion parameter, under the bit rate, decreases as the frame rate increases.
