Abstract

A digital information recording apparatus includes a recording circuit for recording information of a retention period included in the digital information and indicating a period for permitting the digital information to be held in the recording medium, starting with a time at which the digital information is recorded on the recording medium; and information of a playback permission period included in the digital information and indicating a period for permitting the digital information to be played back starting with a time at which the information is reproduced initially following recording of the digital information on the recording medium, permitting temporary recording or copying for the information permitted for “copy never” or “copy one generation.”

Claims

1. A digital information recording apparatus for recording digital information including video information and/or audio information on a first recording medium, comprising:

a recording circuit for recording move permission information included in said digital information;

said move permission information permitting said digital information to be moved to a second recording medium on the premise that at least a part of said digital information on said first recording medium is disabled for playback, even when said digital information is inhibited from being copied.
