N2 - In this paper, we propose the bit-rate control scheme for the block based video coding like H.263(+) or MPEG-4. The proposed scheme is designed to identify the quantization parameter set through the Lagrangian optimization technique using the histogram based R-D estimation. We calculate the quantization parameter set using the Viterbi algorithm to solve the Lagrangian optimization problem considering the Dquant method of H.263(+) or MPEG-4. The proposed scheme improves the video quality by up to 1.5 dB compared with the TMN8 rate control scheme, and it is more effective in the video sources with dynamic activities of bits than the consistent quality approaches.
