摘要：
A system for compressing digital data by representing a portion of it predictionally and transformationally as a block of transform coefficients, then quantizing that block selectively into a set of encoding symbols based on an indication whether the transform coefficients represent the portion as having a particular characteristic, and then by encoding the set of encoding symbols into a data bit stream. In particular, frequency may be used as the characteristic of the digital data in many applications.
