| Parametric bitstream-based quality assessment of progressive download and adaptive audiovisual streaming services over reliable transport – Quality integration module |
Recommendation ITU-T P.1203.3 specifies the quality integration module for Recommendation ITU‑T P.1203. The ITU-T P.1203 series of ITU-T Recommendations specify modules for monitoring the audio, video and audiovisual quality of video services such as adaptive bit-rate video streaming. The respective ITU‑T work item has formerly been referred to as P.NATS (parametric non-intrusive assessment of TCP-based multimedia streaming quality). The ITU-T P.1203.3 part of Recommendation ITU-T P.1203 can be applied to the monitoring of performance and quality of experience (QoE) of video services such as adaptive bit-rate video streaming. Besides stream-based input information, the ITU-T P.1203.3 quality integration module takes the per-one-second video- and audio-quality scores calculated according to ITU-T P.1203.1 and ITU-T P.1203.2, respectively, as input.
Only one quality integration module is recommended for all four modes 0 to 3 of the Recommendation ITU-T P.1203 model series, unique across all modes.
This Recommendation includes an electronic attachment containing the 20 trees described in clause 8.4.
This revision to Recommendation ITU-T P.1203.3 (2007) replaces equation (20) in clause 8.3.
