500. On the list of standardized procedures is the Double Stimulus Impairment Scale (DSIS). In DSIS, Every single expert sights an unimpaired reference video, accompanied by an impaired Variation of exactly the same video. The professional then charges the impaired video utilizing a scale starting from "impairments are imperceptible" to "impairments are quite troublesome."
At that point, Microsoft Promoting will make use of your comprehensive IP deal with and consumer-agent string so that it may correctly system the ad simply click and charge the advertiser.
