    Implementacja w układzie reprogramowalnym operacji kwantyzacji odwrotnej na potrzeby wewnątrzramkowej dekompresji wideo
    (Wydawnictwa AGH, 2010) Cichoń, Sławomir
    Video data quantization is present, in different variations, in almost all video compression algorithms. Its purpose is to reduce less important data, while at the same time increase the efficiency of video compression, in the consecutive variable length coding process. In this paper preliminary scaling and quantization algorithms used in digital video standard (DV - Digital Video), will be described in details. Implementation of inverse quantization algorithm in the pipeline architecture, as one of processing elements in complete DV decoder, will be presented.
