Abstract
Three kinds of visual services, namely highly band-compressed, conventional, and high definition, are considered. Evaluation in terms of factors basic to all three classes are considered. The picture quality scale (PQS) is discussed, and its use in assessing color image coding and coder design is examined. Deterioration of moving images due to blur and to field or frame repetition is addressed. The problems relevant to high-definition visual services are described.<>
