Towards Video Quality Metrics for Hdtv

High Definition Television (HDTV) is the new generation broadcasting system, proposing a deeper immersion in action and better visualization comfort. New material is used (flat television screens, fast connection, high media storage, etc.) allowing better user experience than standard definition television (SDTV). Higher hardware prices will only be accepted if noticeable higher quality is reached. However, new features bring specific distortions but also enhancements for global quality. New techniques of quality assessment need to be developed in order to characterize the impact of each element in the HDTV chain. The last step of the quality measurement is the complex combination of every quality contribution providing experience quality measurement for the whole system.
