The goal of this project is to identify and evaluate alternatives for, and to contribute to the planning of a video quality program within a digital video service provider. The project addresses the issue of objective video quality measurement and proposes a methodology for ongoing video quality monitoring. It will also explore the use of real time monitoring and control of video encoder parameters, in order to improve the quality of streams which could benefit from higher encoding bit rates, while respecting the overall bandwidth constraints associated with the access network by encoding other streams at lower bit rates when their quality will not be adversely affected. In order to accomplish this, data will be collected on the channel changing behaviour of users as well as on the quality of video as a function of the encoding parameters, such as minimum and maximaum bit rate and quality factor. This data will be used to develop a simulation model which can in turn be used to develop real-time algorithms for the control of bit rates and quality.
