Abstract: In this paper, we propose a method of motion-compensated up-conversion from TV resolution to HDTV resolution for compatible coding. The proposed method obtains the motion information for up-conversion from the motion vectors included in the lower layer. The algorithm has advantage in obtaining motion vectors for up-conversion without extra transmission. Simulation results show that the spatial prediction by the proposed up-conversion method gives a better performance than the conventional one, also that the coding efficiency of the higher layer is improved.!5
