The paper presents a system practicallz achieved, using a complete computer IBM-AT for processing of the TV images. In the first part of the paper it is summarily described the theory and achieved architecture.In the second part there are presented the experimental results obtained, concerning the compression of the images. The informational boom in the last decades had a strong impact on image transmission techniques. Generally accepted statistics state that 83 % of the information is received visually. That is why the research in video technology is so important. Nowadays, most of the TV networks use analogue transmission of images but the necessity of enhancement of image quality imposed high definition television (HDTV). At the same time the problem of bandwidth for the transmitted signal is important as well. In order to have a narrows transmission bandwidth, several information compression methods are used. Almost all of them utilize numerical methods and digital transmission techniques.
