A new buffer control strategy for image data compression

In video coding, a rate buffer control strategy is important. The paper introduces a new rate buffer control using a nonlinear relationship between the buffer occupancy and the quantization step size. A piecewise linear relationship is also considered to obtain a better utilization of buffer. The strategy is implemented on H.261 in simulation. In simulations, it was shown that a better SNR ratio can be obtained by the proposed strategy.<
