Abstract

PURPOSE:To enable recorded details to be confirmed readily by recording an index information of a recorded video details into an IC memory card as a voice information and a tape count information and then outputting the index information based on the recorded data. CONSTITUTION:When an index record mode button 13 is turned on when recording an index information, a control circuit 12 sends out a current value of a counter memory on a magnetic tape 7 to an IC memory card device 9, switches a selection switch 6 tentatively, and then inputs voice information of index of a recorded video from a microphone 1. The information is written into an IC memory card 8 along with a signal related to a tape count information from the circuit 12 at the device 9 through a processing part 5 and an A/DC 10. When confirming the recorded details, turn on a button 14. Then, the circuit 12 sets the device 9 to read mode, reads the details of a card 8, sends it to a TV2 through the A/DC 11 and the processing part 5, and then sends it to a LOUT terminal 4 for confirmation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to video tape recorders such as stationary VTRs and camera-integrated VTRs.

(Prior art) With a conventional VTR, if you want to check the recorded content, a practical method is to put the VTR in playback mode, fast forward or rewind the tape in that state, and check the recorded content. It will be done. In addition, an index signal is injected onto the tape between the first recording part and the second picture part in advance,
When checking the recorded contents, it is conceivable to fast-forward or rewind the tape to detect the index signal without setting the VTR to playback mode, and at the same time set the VTR to playback mode to check the # picture content. According to this method, recorded content can be checked more quickly than by fast forwarding or rewinding in the playback mode.

(Problem to be Solved by the Invention II) In the above-mentioned prior art, both methods require a minimum amount of time to send the tape, and there is a problem in that the recorded content cannot be checked instantly.

In the same figure, when recording index information,
Turn on the index recording mode button 13. Then, the control circuit 12 sends the current time of the counter memory on the magnetic tape 7 to the IC memory card device 9,
Thereafter, the selector switch 6 is switched to activate the microphone 1 for, for example, 5 seconds, and words related to the recorded video content, such as audio information that serves as an index, such as "O month O day, sports day", are input from the microphone 1. That will happen. This audio information is made into an appropriate size by the audio processing unit 5 and converted into digital data by the A/D-CIO.

Thereafter, in the IC memory card device 9, the digital audio signal is written into the IC memory card 8 together with the digital signal related to the tape count information sent out earlier from the control circuit 12.

Moreover, when the user wants to check the recorded contents, the index check mode button 14 is turned on. Then control circuit 1
