A new bit allocation scheme for fine-granular-scalability (FGS) video coding is proposed. Differing from traditional bit allocation schemes, the focus is on understanding the relationship between rate-distortion analysis and nonzero binary-scaled coefficients (NZBC) in the bitplane coding. An optimal strategy for NZBC coding is then derived and experimental results are given for a comparison of the new scheme with uniform bit allocation.
