This rule can be inverted to store a 0 if the run begins with a 0 bit, but the effect is the same as long as both the encoder and the decoder of the inversion list agree on this detail.
如果开始出现的是 0 ，那么这个规则需要改变，但效果是一样的，因为编码器和解码器都遵循这一规则。

The input bit rate and the output frame rate of video decoder is fix, so a Rate Buffer is needed to balance this rate difference.
而经解码后显示的侦速率是恒定的，这就要求在解码端有一个缓冲器来实现输入码率与输出码率间的过渡。

The serial structured decoder can decode one bit per cycle. Because the structure of UVLC(Universal Veriable Length Code) is fixed, "first one detector"is designed to decode UVLC.
