Video quality evaluation for Internet streaming applications

Abstract

We carried out a number of subjective experiments using typical streaming content, codecs, bitrates and network conditions. In an attempt to review subjective testing procedures for video streaming applications, we used both Single Stimulus Continuous Quality Evaluation (SSCQE) and Double Stimulus Impairment Scale (DSIS) methods on the same test material. We thus compare these testing methods and present an analysis of the experimental results in view of codec performance. Finally, we use the subjective data to corroborate the prediction accuracy of a real-time non-reference quality metric.
