摘要：This invention provides a parameter for use in assessing video quality based on temporal frame freezing for use in an apparatus and method for perceptual video quality measurement. The invention provides a method of generating a freeze frame parameter
relating to the perceptual impact of frozen frames in a video signal comprising the steps of: identifying frozen frames; identifying a freeze event comprising a plurality of consecutive frozen frames, the freeze event having a duration in dependence upon the number of frozen frames in said sequence; defining a set of duration ranges; and generating a freeze frame parameter in dependence upon the number of freeze events having a duration falling within each duration range. Methods and apparatus for perceptual video quality measurement using the method are also provided.
