Claim:
1. A method of determining a quality value of a video stream transmitted to a media player, the method comprising, for a measuring interval of the video stream: identifying at least two lost data packets of the video stream, identifying intra coded frames of the video stream, determining, for each of the intra coded frames identified, that the intra coded frame has a maintained image quality if none of the lost data packets identified are associated with the intra coded frame, estimating, for each of the lost data packets identified, a distance between that lost data packet and the next intra coded frame that occurs subsequently to the lost data packet in the video stream and that has a maintained image quality, wherein said distance is defined by the difference between a frame number associated with the lost data packet and a frame number of the intra coded frame, and generating the quality value, based on the distances.
