Quality and Usability


Motivation & Project Description

  • Currently, no standardized parametric or mixed parametric/signal-based prediction models are available for video and audio-visual services; T-V-Model will provide estimates of quality on the basis of a parametric description of the video processing path.
  • T-V-Model predictions can be used for:
    • Planning networks and services
    • Monitoring service quality
    • Defining & verifying Quality of Service (QoS) classes and Service Level Agreements (SLAs).


Expected Outcome:

  • Audio-Visual Quality parametric model for IPTV and VoD (Video on Demand).
  • Video and Audio processing tools.
  • Audio-Visual test databases.
