The Video-Matte, a new technique developed by NHK for video synthesis in television, enables the synthesis of two location pictures into one which looks quite natural. Unlike the chroma key, Video-Matte does not require a costly color background for video synthesis. A key signal can be generated easily and at will on the monitor screen by means of computer graphics. This technique will help producers cut costs substantially.
