Abstract
There is provided a digital information supply and management system comprising a supply unit, a management unit, and a terminal unit, in which digital information including digital video and audio information is supplied from the supply unit to the terminal unit, and the management unit manages utilization of the digital information in the terminal unit. In this system, the supply unit comprises digital information generating means for generating the digital information; management information generating means for generating management information for the digital information; and information synthesis means for synthesizing the digital information and the management information to generate synthetic information. The management unit comprises accumulating means for receiving reported contents from the terminal unit. The terminal unit comprises receiving means for receiving the synthetic information supplied from the supply unit; management information separating means for separating the management information from the synthetic information; management information processing means for processing the management information; report contents storage means for storing contents to be reported to the management unit, corresponding to the management information; and operating means for accepting an operation by a user to the digital information. Therefore, the contents to be reported to the management unit can be limited by making the management information have instructions relating to report of the contents from the terminal unit to the management unit. As a result, the management unit requires no storage means, leading to a reduction in work load for analysis.
