说明：一种具有在场和帧图中出现所有宏块类型和子块类型的编码比特流。
Specification: One kind of bitstream which contains all types of Macroblocks and blocks in the frame and the field.
同时，在JPEG 2000中基于子带、码块和比特平面的编码都可以并行实现。 因此，MQ编码器的效率就成了JPEG 2000硬件高速实现需要解决的关键问题。
The MQ coder is adopted in JPEG2000. In EBCOT algorithm, the tiles, code-block, bit-plane all can be implemented using parallel structure.
分形编码的时间主要花费于在一个海量码本中搜索每个输入子块的最佳匹配块。
The time to encode fractally an image is mostly spent on searching for the best-matched block for each of range blocks in a usually-large domain pool.
