Patent ID: 8339976

Claim:
A method of determining multimedia quality, the method performed in a receiver and comprising the steps of: receiving a multimedia sequence comprising video and audio data; extracting one or more input parameters derived from a data transport layer and one or more video-streaming player parameters associated with the received multimedia sequence; generating a quality value corresponding to a subjective quality score of the multimedia sequence based on at least one of the extracted input parameters; and outputting the quality value as a measure of the quality of the received multimedia sequence; wherein the quality value is calculated as TOT_MOS pred =func(Qual encoding ,Qual buff ,Qual pl ), where Qual encoding is a measure of the quality of video encoding; Qual buff is a measure of the impact on the quality value of initial buffering time, re-buffering percentage, and re-buffering frequency; and Qual pl is a measure of the impact on the quality value of packet loss.
