In this algorithm, by initially setting a larger threshold of rate-distortion slope and marking the channels that their rate-distortion slopes are larger than the thresholds in each coding block as "selected state", and then decreasing the threshold step by step until the sum of the rate of those selection exceeds the predefined rate limitation, an approximate optimal truncation point will be obtained.

本算法通过初始设置一个较大的长度－失真斜率阈值，将每个编码块中长度－失真斜率大于该阈值的通道置为"选入"状态，逐次减小该阈值并重复上述过程，直到状态为"选入"的通道的累积码流长度大于设定的码流长度，得到近似的最优截断点，再采用舍弃最小斜率的方法获得最优截断点以实现码率控制。
