The process of converting, or digitizing, the almost infinitely variable amplitude of an analog waveform to one of a finite series of discrete levels. In video compression, quantization is a process that attempts to determine what information can be discarded safely without a significant loss in visual fidelity. The quantization process is inherently lossy because of the many-to-one mapping process. [Source: Xilinx Web site]
