本文概述电视信号数字编码的研究在过去十年中的进展。以广播电视信号编码实用化为重点,介绍各种数据压缩编码法(帧内与帧间的预测法和变换法)的理论发展,以及计算机模拟实验和典型硬件试验系统的状况。由此讨论电视信号编码研究进展的特点和发展前景。
This article outlines the progress made in the research on digital coding of television signals over the past decade. In order to put emphasis on the practical application of broadcast signal coding, this paper introduces the theoretical development of various data compression coding methods (intra-frame and inter-frame prediction and transform methods), as well as computer simulation experiments and typical hardware test systems. This paper discusses the characteristics of the research progress of television signal coding and its development prospects.
