The integration of the mobile network with the fixed network, by using IP, has allowed the appearance of packet-based videoconference between fixed and mobile devices. Current mobile IP networks are sized for http traffic and its behavior is best-effort. In this context, it becomes compulsory to evaluate and measure the video quality when packets are transmitted through these networks. By doing this, results obtained could be used to size future networks and/or define different Quality of Service politics in future IMS networks. The objective of this final career project is to evaluate possible video quality degradation in videoconference applications through IP integrated network (fixed + mobile). A study of the currently available video quality evaluation tools will be made and, as well, a specific system for the video quality evaluation in communications between the IP fixed network and the 3.5G IP mobile network, using own methodology, will be developed. Several evaluation scenarios will be defined, with different mobile – fixed network configurations in order to identify the elements susceptible of degradate the quality of the video. The developed system must be able to process the video sequences in origin and in reception, so it will be a referential system.
