Information processing apparatus, display unit, digital content distributing system and digital content distributing/outputting method

摘要

The present invention protects the right of a digital content, and enables final output of the digital content in a form of stimulating user's visual and auditory desire. An information processing apparatus main body transfers a digital content (display data) encrypted by using an encrypted key information shared with a display unit while the display unit performs a decryption process on the display data transferred from the information processing apparatus main body by using the encryption key information. Herein, the display data transferred from the information processing apparatus main body to the display unit is encrypted only in a part thereof, e.g. display data is encrypted in an amount of several lines every several lines.
