摘要： If content is transmitted/received through a digital signal bus, protection of copyright causes a problem because of no deterioration in quality. Accordingly, authentication is required. The quantity of information to be processed is, however, so large that a long time is required for authentication. Accordingly, both achievement of handling property as in conventional analog connection and protection of copyrighted content without user's awareness become an object. The foregoing object can be achieved by authentication which is executed, for management of copyright, among apparatuses connected to the digital signal bus when the apparatuses are powered on or connected to the digital signal bus or when an input terminal connected to the digital signal bus is selected. The object can be further achieved by an encryption key shared among these apparatuses.

摘要： A digital signal recording apparatus is disclosed, which is capable of protecting the copyright of the analog input information encoded into a first digital signal in a recording medium. A second digital signal encrypted based on the key information and the input analog signal encrypted based on the key information are converted into a second digital signal and encrypted, and the resulting signal is selectively recorded in a recording medium. The digital signal recording apparatus further comprises a circuit for encrypting the digital signal converted from the input analog signal with a key obtained by a predetermined calculation of the key information according to a scheme similar to the second digital signal protection scheme through a digital interface, and a signal recording circuit for recording the key information and the encrypted digital signal in a recording medium.
