ITU-T Recommendations

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 bitrate 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 bitrate video streaming. Besides stream-based input information, the P.1203.3 quality integration module takes the per-one-second video- and audio-quality scores calculated according to P.1203.1 and 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.
