    In this paper, we define the concept of digital actors and show their importance in the future interactive digital television and multimedia. We discuss the applications of these digital actors in the new multimedia services especially for training and education. We summarize the main techniques to create and control these digital actors and emphasize the importance to develop new tools for the co... View full abstract»

    We first discuss the position of cameras and displays in digital television systems. It is difficult to realize these devices in digital form so cameras and displays will remain analog for some time, even after television signal processing is implemented digitally. Nevertheless, the importance of camera and display in television systems will not diminish. These devices will always be key elements ... View full abstract»

    The Grand Alliance (GA) was formed to define and construct a system for the delivery of HDTV using terrestrial broadcast channels. This system is composed of the best components from previously competing systems considered by the FCC. MPEG-2 syntax is used with novel encoding techniques to deliver a set of video scanning formats for a variety of applications. The paper focuses on video compression... View full abstract»

    Television that conveys real-time information has become an indispensable part of our lives. Its technology has advanced from the days of black-and-white sets to color models and to high-definition television (HDTV). HDTV has been contrived to provide the audience with greater immediate appeal such as sensation of reality and power than the current TV system does and its worldwide applications are...

    High definition television (HDTV) services will play the most important role in the digital television systems for the future. HDTV is already broadcast daily in Japan and advanced television (ATV) standards will soon be established in the US. The hardware systems for two HDTV systems, the 1125/60 and 1250/50 systems, have already been developed. Their outlines are described in the paper. Signal p... View full abstract»

    Interactive television (ITV) is a new form of residential consumer video service that gives viewers far greater control over the contents of programs than is possible with conventional television. There are substantial technical challenges to offering a ITV service on a large scale, both in content creation and delivery. The paper discusses those challenges and presents a new system architecture f... View full abstract»

    Through mutual technology transfer between consumer and professional video recorders, the last 20 years has witnessed a rapid evolution from analog to digital recording. Each new digital videotape recorder (VTR) uses different channel coding. This implies that improving the recording density involves the development of new channel-coding schemes together with evolutionary magnetic tapes and heads.... View full abstract»
