Parametric bitstream-based quality assessment of progressive download and adaptive audiovisual streaming services over reliable transport – Audio quality estimation module

Abstract

Recommendation ITU-T P.1203.2 specifies the short-term audio quality estimation module for Recommendation ITU-T P.1203. The ITU-T P.1203 series of ITU-T Recommendations specifies modules for a set of model algorithms for monitoring the integral media session quality for transport control protocol (TCP) type video streaming. The models comprise modules for short-term video-quality and audio-quality estimation (the latter specified in this Recommendation). The per-one-second outputs of these short-term modules are integrated into estimates of audio-visual quality and together with information about initial loading delay and media playout stalling events, these are further integrated into the final model output, the estimate of integral quality. The respective ITU-T work item has formerly been referred to as parametric non-intrusive assessment of TCP-based multimedia streaming quality or P.NATS. The Recommendation ITU-T P.1203.2 part of Recommendation ITU-T P.1203 provides details for the module for bitstream-based, short-term audio quality estimation.
