A Fast Wavelet-Based Video Codec and its Application in an IP Version 6-Ready Serverless Videoconferencing System

The purpose of this paper is twofold: On the one hand, we propose a fast waveletbased 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.
