Scalable video coding is attractive due to the capability of reconstructing lower spatial resolution, or lower quality, or lower frame rate video signals from partial bit streams. It enables a simple solution in adaptation to different requirements from network, terminal and storage capabilities. In this thesis, a 3D wavelet based scalable video codec (SVC) is proposed through the integration of motion-compensated temporal filtering (MCTF) and JPEG2000. By exploring the unique features of MCTF and JPEG2000, the proposed simple codec not only achieves a comparable rate distortion (RD) performance but also has the properties of high scalability and error resilience. The main contributions of the developed codec lie in its simple architecture and the optimum bit allocation scheme based on the quality layer concept of JPEG2000.
