Subjective and objective video quality assessment. A parametric model for digital television coded with H.264

This paper analyses the background of the procedures to assess video quality. It outlines the methodology to perform valid subjective tests, as well as the basic aspects of objective methods. All along the paper some experiences, resources and tools developed by the VQI Project (http://ingenieria.um.edu.uy/vqi) are presented, in particular a parametric model for digital television coded with H.264.
