Abstract (in Japanese) (See Japanese page) 
(in English) We have studied new operation methods, accompanied with change for file-based systems from VTR-based ones, and thus we developed a digital watermarking equipment for broadcast use. This equipment is composed of two input patterns. In a long sentences input pattern, each sentence of a constant length is hidden in program sequences as digital watermarks by turns. After each received one is extracted, it is displayed on the screen altogether. In an ID input pattern, each ID with a length of several bits is hidden in program sequences as digital watermarks. Received one is extracted, and the information such as a sentence, a figure and a logo mark, is displayed by referring to the file list for the extracted ID.
