1. A digital information recording-reproducing apparatus which records and reproduces a digital information signal, comprising:
- a recorder which records the digital information signal together with control information; and
a reproducer which detects the recorded control information at a time the recorded digital information signal is to be reproduced, and reproduces the recorded digital information signal only if the detected control information satisfies a predetermined condition;
wherein the control information includes type information specifying a type of the digital information signal and a predetermined condition under which the digital information signal is allowed to be reproduced;
wherein the reproducer reproduces the recorded digital information signal only if the predetermined condition specified by the type information is satisfied at a time the recorded digital information signal is to be reproduced; and
wherein the reproducer reproduces the recorded digital information signal only if a time at which the recorded digital information is to be reproduced is within a time period during which the recorded digital information signal is allowed to be reproduced.
