AIPA-members, as part of the T-Labs’ T-V-model team, are the co-recipients of the 2013 Deutsche Telekom Patent Award for their work on audio-visual quality monitoring of media services and IPTV (Bonn, 23 May 2013).

Under the Co-lead of the AIPA-group, six new standards have been issued by ITU-T: P.1201, P.1201.1, P.1201.2, P.1202, P.1202.1, and P.1202.2. The standards developed under the working titles P.NAMS and P.NBAMS describe different packet-header- and bitstream-based quality prediction algorithms for monitoring the audio, video and audiovisual quality of video streaming services. In particular, P.1201.2 and P.1202.1 contain significant portions of AIPA’s/T-Labs’ “T-V-model”.

ITU-T Recommendations by series: P series
Announcing consent of new P.1200 - series Recommendations

The audiovisual quality model “T-V-Model” (see T-V-Model++ project) won the ITU-T Q.14 P.NAMS Higher Resolution application and the ITU-T Q.14 P.NBAMS Mode 1 competition for Lower Resolution application. The models are standardized under the ITU-T P.1201.2 and ITU-T P.1202.1 Recommendations (Sept. 2012).

An authoring group led by AIPA (Janto Skowronek, Katrin Schoenenberg, Alexander Raake) wrote for the ITU-T workgroup Q12/18 (headed by Gunilla Berndtsson, Ericson and Janto Skowronek, AIPA) a standard and a supplementary document. Both are in force since July 14:

Recommendation P.1301 "Subjective quality evaluation of audio and audiovisual multiparty telemeetings"

Supplement 26 "Scenarios for the subjective quality evaluation of audio and audiovisual multiparty telemeeting"
