N2 - In motion compensation (MC) based video coding system, macroblock data is always predicted by its temporal neighborhood in its previous frame. In this work, we observe that the macroblock data can often be better predicted by its spatial neighborhood than its temporal neighborhood, especially at low coding bit rates. Based on this observation, we propose a joint temporal-spatial compensation (JTSC) scheme for video coding, with the conventional MC being its subset. Our experimental results demonstrate that the coded picture quality is significantly improved by this novel JTSC scheme.
