Light-weight audiovisual quality assessment of mobile video: ITU-T Rec. P.1201.1
Kazuhisa Yamagishi, Shan Gao · 2013
Significant progress has been made in the recent years in the development of technologies for encoders, decoders and networks. As a result, content, network, and Internet service providers can deliver video content over IP networks. To provide a high-quality service, the quality of experience (QoE) is becoming much more important. Since QoE is affected by such factors as the audiovisual content, encoding and decoding techniques, and network performance, service providers should monitor the QoE of a communication service in real time to confirm its status. To do this, a quality monitoring tool is necessary. The International Telecommunication Union - Telecommunication Standardization Sector Study Group 12 (ITU-T SG12) has studied the parametric non-intrusive assessment of audiovisual media streaming quality (P.NAMS). The P.NAMS - lower resolution application area was finally standardized as ITU-T Recommendation P.1201.1 in October 2012. The P.1201.1 model can be used for estimating audio, video, and audiovisual quality for mobile audiovisual media streaming using packet headers. Since the model analyzes only packet header information, the computational power of the model is very light, and the model can be applied to encrypted packets. This paper describes the P.1201.1 model and its performance.
