This book is Dictionary of Audio-Visual Terms. This book interpreted the term audio-visual in the generous sense, embracing the preparation and presentation of pictures and sound by film and video as well as by tape-slide, film-strip and multivision. Many of the boundaries which formerly divided photographic and electronic methods or recording and reproduction have tended to disappear during recent years and the interchange of these media now frequently provides and additional tool in the hand of creative producer as well as extended facilities for exhibition . Motion picture film and still slide are incorporated in video productions, videotape is transferred to film, and tape-slide shows are converted to both film and videocassettes for alternative methods of distribution. There is thus ample justification for treating these varied disciplines within the same volume on a common basis. The actual display of images in computer graphics and computer animation is an obvious example but computer controlled operations in video and sound production, in animation photography and in motion picture processing are of increasing importance, while complex multi-screen shows involving dozens of projectors and hundreds of individual slides benefit greatly in both programming and presentation from the facilities available through microprocessors. //yn
