In this work, we present a video coding system based on 3D subband coding with motion compensation (MC-3DSBC) which is novel both in its generation of 3D subbands and in their subsequent encoding. The rate allocation from the GOP level to each class of subbands is optimized by utilizing the structural property of MC-3DSBC that additive superposition approximately holds for both rate and distortion at the unit level. Experimental results show that the performance of the proposed video coding system exceeds that of an MPEG-1 implementation for several video test sequences covering various camera and object motions.
