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

Abstract

Recommendation ITU-T P.1203.1 specifies the short-term video representation quality estimation modules for ITU-T P.1203 (Pv module). The ITU-T P.1203 series of 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 (described in this part of the Recommendation family) and audio-quality estimation. 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, they are further integrated into the final model output, to provide the estimate of integral quality. The respective ITU-T work item has formerly been referred to as the parametric non-intrusive assessment of TCP-based multimedia streaming quality, or P.NATS. The ITU-T P.1203.1 part of ITU-T P.1203 provides details for the modules for bitstream-based, short-term video quality estimation.
