Patent ID: 8885050

Claim:
A method of monitoring a perceptual quality of video in a perceptual quality monitoring system, the perceptual quality monitoring system including a data collection component, a parameter estimation component, and a video quality estimation component, the method comprising the steps of: receiving, at the data collection component, an encoded input video bitstream containing predetermined information and at least one video frame; generating, by the parameter estimation component from at least some of the predetermined information contained in the encoded input video bitstream, a plurality of video quality parameter estimates including at least a frame rate parameter estimate and a packet loss rate parameter estimate; generating, by the parameter estimation component, a coding bit rate parameter estimate as a function of the frame rate parameter estimate and the packet loss rate parameter estimate, the perceptual quality monitoring system further including a video frame complexity estimation component; generating, by the video frame complexity estimation component, an estimate of the complexity of the at least one video frame using at least some of the predetermined information; generating, by the parameter estimation component, a normalized version of the coding bit rate parameter estimate using the estimate of the complexity of the at least one video frame; providing, by the parameter estimation component, indications of the normalized version of the coding bit rate parameter estimate, the frame rate parameter estimate, and the packet loss rate parameter estimate to the video quality estimation component; and generating, by the video quality estimation component, an estimate of the perceptual quality of the video using at least the normalized version of coding bit rate parameter estimate, the frame rate parameter estimate, and the packet loss rate parameter estimate.
