P.NATS Phase 1 - TU Ilmenau part of all winning groups

Building blocks of the ITU-T P.1203 model

The International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) has recently published the P.1203 series of recommendations. This standard is the first which allows to measure the quality of different streaming services such as YouTube, Netflix etc. The standardized models were developed in a competition within the ITU-T Study Group 12 (SG12) which was previously referred to as the P.NATS (Parametric Non-intrusive Assessment of TCP-based multimedia Streaming quality) consisting of seven participating companies. The standardized models are available in four modes of operation depending on the different levels of media-related information used for analysis which in turn reflect the different types of media stream encryption. The models are developed to assess the quality of streaming services up to HD resolution. A modular model framework has been used to develop the models. This modular architecture is as shown in the figure.

TU Ilmenau in collaboration with Deutsche Telekom has been part of the winning groups for all the four modes.

QoMEX 2017

In May 2017, the Audiovisual Technology Group of TU Ilmenau organized the 9th International Conference QoMEX 2017 in Erfurt. The conference brought together leading experts from academia and industry to present and discuss current research on multimedia quality, Quality of Experience (QoE) and user experience.

Book "Quality of Experience"

The book "Quality of Experience" appeared in 2014. Alexander Raake is the co-editor, and many other former members of the AIPA team are co-authors of different chapters. The book:

  • develops the definition of "Quality of Experience" for telecommunication services and applies it to various fields of communication and media technology
  • provides examples and guidelines for many fields of application
  • • was written by well-known experts in the field
