In the last decade, telecommunication industry has been widely developed in area of the multimedia interactive services. Actually, there are still emerging new videoconference and instant messaging applications. For the provisioning of multimedia interactive services it is essential to provide a required level of customer satisfaction, given by the end-user quality. The video and audio compression improvement of the newest video coding standards H.264/AVC and AAC allows for providing video and audio streaming for low bit and frame rates while preserving the perceptual quality. This is especially suitable for interactive multimedia applications in 3G wireless networks. The aim of this thesis was to design the ”State of the Art” video conferencing environment supporting H.264/AVC and AAC codecs. Moreover, this environment provides opportunity to analyze end user quality at all layer of OSI model. As a result of this design, we have an open source application, that offers a good quality of image and sound at very low rates (90kbps, 9fps for video) at the same time that reduces the reception delay that now exists in commercial applications.
