The purpose of this paper is twofold: On the one hand, we propose a fast wavelet-based video codec which is implemented into a real-time video conferencing tool. The proposed codec uses temporal frame difference coding, a computationally low-complex 5/3 tap wavelet transform, and a fast entropy coding scheme based on Golomb–Rice codes. On the other hand, we present an application of the video conferencing tool in a serverless peer-to-peer IP-based communication framework. For mobile communication we propose a simple, ready-to-use location scheme for video conference users in a global network.

The rapid development of information technology-based communication to encourage the development of video conferencing applications to a variety of media platforms. One of the media that is easily accessible is a web application development based RIA (Rich Internet Application). In this study developed a flash-based video conferencing application to utilize the net class group in ActionScript 3.0 and multimedia protocols RTMFP (Real Time Media Flow Protocol). Streaming video delivery technology requires codecs to be able to transmit video and audio. To find out which one is suitable codec in the development of this application, the analysis is done where appropriate codec for video conferencing on the public network access in terms of the quality of the resulting. The conclusion of the implementation and analysis of three types of audio codecs and codec, is that the codec h.264 and h.264 base profile play a video codec that is suitable for public networks because it produces little noise when there is a lot of movement when compared to the Sorenson video codec.
