Motion information scalability is an important requirement for a fully scalable video codec, especially for decoding scenarios of low bit rate or small image size. So far, several scalable coding techniques on motion information have been proposed, including progressive motion vector precision coding and motion vector field layered coding. However, due to the interactive compatibility issue with other scalabilities, i.e. spatial, temporal, and quality, a complete solution that integrates most of the desirable features of motion scalability is not yet seen. In order to solve the problem, we have recently proposed a fully scalable motion model which offers full functionalities for motion scalability with no compatibility issues. In this paper, we further investigate some coding algorithms for proposed scalable motion model. The purpose is to minimize the coding overhead introduced by motion scalability. Simulation results will be presented to verify the significant improvements using proposed coding and optimization algorithms.
