Recommendation ITU-T P.1201.11 describes an algorithmic model (ITU-T P.1201-LR: Parametric non-intrusive assessment of audiovisual media streaming quality - Lower resolution application area) for monitoring the audio, video and audiovisual quality of IP-based video services based on packet-header information. ITU-T P.1201.1 addresses the lower resolution (LR) application area, including services such as mobile TV. The ITU-T P.1201-LR model is a no-reference (i.e., non-intrusive) model which operates by analysing packet header information. Further input information on more general aspects of the stream, such as the video resolution, which may not be available from packet header information, is provided to the algorithm out-of-band, for example in the form of stream-specific side information. As output, the model provides individual estimates of audio, video and audiovisual quality in terms of the five-point absolute category rating (ACR) mean opinion score (MOS) scale. This Recommendation is to be used with media payload (audio, video) encapsulated in RTP/UDP/IP packets.

1 This Recommendation includes an electronic attachment for testing compliance.
