Abstract
In this paper, we present theoretic analysis of optimal bit allocation in prediction-based video coders. Usually, the optimal bit allocation is to minimize the sum of frame distortions under a total bit rate constraint. We use the Laplacian model to describe the distribution of DCT coefficients of residual frame and analyze the dependency between reference frame and predicted frame at different bit rates. Then we found that inter frame dependency will increase as bit rates decrease. Finally, based on this rule, we give some suggestions for rate allocation in practical video coding. © 2008 Springer.
