Abstract
Abstract A management system of a multimedia comprises a multimedia apparatus and a multimedia controller for managing and controlling the multimedia apparatus. The management system has processing means for transmitting and receiving a message between the multimedia controller and the multimedia apparatus, for automatically setting a predetermined name with respect to an owner of the multimedia apparatus, and for automatically or manually setting predetermined attributes with respect to attributes. The presence or absence of the right to access to the multimedia apparatus is judged in accordance with the contents of the attributes. By setting the multimedia apparatus itself to an object, a multimedia apparatus object is constructed in the multimedia apparatus. A circuit to manage a self secret protection is provided in the multimedia apparatus object. By setting a file in the multimedia apparatus to an object, attributes and an owner of the file are concealed in the file object, thereby protecting the secret of the file object.
