Low Bitrate Video and Audio Codecs for Internet Communication

Abstract: This master thesis discusses the design and the implementation of an own developed wavelet-based codec for both video and image compression. The codec is specifically designed for low bitrate video with minimum complexity for use in online gaming environments. Results indicate that the performance of the codec in many areas equals or even surpasses that of the international JPEG 2000 standard. We believe that it is suitable for any situation where low bitrate is desirable, e.g. video conferences and mobile communications. The game development company Moosehill Productions AB has shown great interest in our codec and its possible applications. We have also implemented an existing audio solution for low bandwidth use.
