Method, system and apparatus for evaluating video quality

A method for evaluating video quality, comprising:

• obtaining information about a transmitted video, wherein the information comprises at least duration of a video frame;
• resolving the information about the transmitted video to obtain video frame parameters;
• calculating a video frame quality parameter according to the video frame parameters;
• and
• performing a weighting operation for the video frame quality parameter and the duration to obtain a video sequence quality parameter.

An apparatus for evaluating video quality, comprising:

• a video frame obtaining unit, configured to obtain information about a transmitted video;
• a video frame parameter calculating unit, configured to resolve the video information obtained by the video frame obtaining unit to obtain video frame parameters, wherein the video frame parameters comprise a compression distortion parameter and/or a video quality distortion parameter with packet loss;
• and
• a video frame quality parameter calculating unit, configured to calculate a video frame quality parameter according to the video frame parameters calculated out by the video frame parameter calculating unit.

A system for evaluating video quality, comprising:

• an apparatus for evaluating video quality, configured to:
• obtain information about a transmitted video;
• resolve the information about the transmitted video to obtain video frame parameters, wherein the video frame parameters comprise a compression distortion parameter and/or a video quality distortion parameter with packet loss;
• and calculate a video frame quality parameter according to the video frame parameters;
• and
• a sending apparatus, configured to obtain and send the video frame quality parameter generated by the apparatus for evaluating video quality.
