Disney patents method to score video quality using fuzzy logic
Disney describes a system that combines multiple technical measurements of video delivery into a single overall quality score. It uses fuzzy logic, a type of math that handles vague or partial truths, to weigh factors like buffer time and resolution before adjusting how the video is encoded.
In the filing’s own words
In some embodiments, a method receives a plurality of metric values for quality of service based on delivering content in a content delivery system. Respective metric values into a fuzzy value in a plurality of possible fuzzy values where a plurality of fuzzy values is determined. The method determines a plurality of fuzzy rules where a fuzzy rule is associated with a fuzzy value. Respective conditions for fuzzy rules are applied to the plurality of fuzzy values to determine fuzzy rules that have conditions met. A fuzzy rule applies when respective conditions for the fuzzy rule are met by one or more fuzzy values in the plurality of fuzzy values. A fuzzy output is determined from fuzzy values that are associated with the fuzzy rules that have conditions met. A unified quality score is calculated from the fuzzy output. The method outputs the unified quality score.
What exactly they claim (claim 1)
1. A method comprising: receiving a plurality of metric values for quality of service based on delivering content in a content delivery system; converting respective metric values into a fuzzy value in a plurality of possible fuzzy values, wherein a plurality of fuzzy values is determined; determining a plurality of fuzzy rules, wherein a fuzzy rule is associated with a fuzzy value; applying respective conditions for fuzzy rules in the plurality of fuzzy rules to the plurality of fuzzy values to determine one or more fuzzy rules that have conditions met, wherein a fuzzy rule applies when respective conditions for the fuzzy rule are met by one or more fuzzy values in the plurality of fuzzy values; determining a fuzzy output from one or more fuzzy values that are associated with the one or more fuzzy rules that have conditions met; calculating a unified quality score for a quality of experience based on the fuzzy output; and outputting the unified quality score, wherein the unified quality score is used to adjust the content delivery system; and adjusting a parameter in an encoder in the content delivery system to encode content differently based on the unified quality score.
