在以上研究的基础上，用C语言实现了基于有效比特位编码模型和率失真优化技术的码率控制算法。

With the research above, a new rate control algorithm is realized by c, which is based on the valid-bit-number coding model and the rate-distortion optimization technique.

为降低比特率，本文提出四种有效的BTC算法，以降低对每个图像块的两个量化电平和位平面编码所需的比特数。

In order to reduce the bit rate, on the one hand, simple look-up-table methods are presented to code the BTC quantized data of a block.

与其他的错误校验码类似，汉明码也利用了奇偶校验位的概念，通过在数据位后面增加一些比特，可以验证数据的有效性。

And other similar error checking code, Hamming code also makes use of the concept of parity, data bits followed by an increase in the number of bits, can verify the validity of data.
