| Parametric non-intrusive assessment of audiovisual media streaming quality – Lower resolution application area |
Recommendation ITU-T P.1201.1 specifies the algorithmic model for the lower resolution (LR) application area of Recommendation ITU-T P.1201. The ITU-T P.1201 series of Recommendations specifies models for monitoring the audio, video and audiovisual quality of IP-based video services based on packet-header information. The lower resolution application area of the ITU-T P.1201.1 part of ITU-T P.1201 can be applied to the monitoring of performance and quality of experience (QoE) of video services such as mobile TV. The algorithm for the higher resolution (HR) case is specified in ITU-T P.1201.2. See ITU-T P.1201 for details and respective application ranges and limitations of use.
This Recommendation includes an electronic attachment for testing compliance.
