If there is no biological information, the determination is no and the normal step S
The process proceeds to step 16 to perform a reproducing operation (digital output on). Thereafter, the process proceeds to step S17. If the biological information is detected, the determination in step S14 is NO, and in step S15, the biological information comparison determination circuit 52 determines the biological information of the individual (reproduction operator) who pressed the reproduction switch and the photographer included in the reproduction signal. Of the biological information of each other. If the biological information comparison determination circuit 52 determines that the photographer and the reproduction operator match, the determination in step S15 becomes YES, and the flow proceeds to step S16 to perform the reproduction operation (digital output ON). For example, the digital signal is not output, that is, output signals such as digital output off and scramble output are limited, and the process proceeds to step S17.

Step S17 is a process for judging whether or not an end operation has been performed. If the end operation has not been performed, that is, if the stop switch has not been pressed, step S1 is performed.
Returning to 4, if the end operation is performed, that is, if the stop switch is pressed, the determination is yes and the process ends.

According to such a modification, personal authentication can be performed using the remote control transmitter 130, whereby the author who recorded the recording / reproducing signal and the individual who reproduces the recorded recording / reproducing signal can be authenticated. , And settings such as color balance for each individual can be automatically performed.

As a recording / reproducing apparatus according to an embodiment of the present invention, a video camera integrated type V using a magnetic tape is used.
Although described with respect to TR, the present invention relates to a hard disk,
The present invention may be applied to a recording / reproducing apparatus using a recording medium such as a digital video disk. Further, as the recording / reproducing signal recorded by the recording / reproducing device, both the digital video signal and the audio signal are recorded.
Further, the present invention can be applied to other recording / reproducing signals such as a video game program.

[0104]

According to the present invention, reproduction can be performed in correspondence with the author who recorded the recording / reproducing signal and the individual who reproduces the recorded recording / reproducing signal. In addition, it is possible to smoothly supply software such as a digital video cassette recording a movie. Further, the setting of the diopter of the viewfinder, the photographing conditions, and the like for each individual can be automatically performed, and a good impression can be given to the user.
