Abstract
This paper presents a very fast algorithm for a video codec based on H.263. This algorithm includes “fast motion detection”, “fast motion estimation”, and “referred frame selection”. By the algorithm we implement a software-based multipoint-to-multipoint videoconferencing system over an IP network. In the system one can see and talk with other participants (up to 4) in real time simultaneously
