| Abstract: | In this paper an effective MC FGSST structure is explored, which is appropriate for scalable video coding. The structure obtains spatio-temporal-SNR fine granular scalability, and achieves high coding efficiency at the same time. Users can acquire their necessary scalability by choosing and combining them. Then, a high-powered codec solution based on this structure is presented. Sub- sequently , a focus issue on the right number of bit-planes should be used for motion compensation is discussed, and an algorithm is presented for this issue. The proposed codec saves a lot of hardware expense. Simulation results indicate that the performance of MC FGSST structure is superior to that of FGSST structure. |
