Hereinafter, the operation of the televideo with the playback recording confirmation function of the videotape according to one embodiment of the present invention will be described in detail with the flowchart shown in FIG.

First, when the user inserts the video tape T into the video tape storage unit, mounts the video tape T in the deck, and then sets the playback mode by operating the playback key configured in the control signal input unit 10 ( Step 60), the control unit 12 applies a predetermined control signal to the tape driving mechanism 44, the signal recording / reading unit 46 and the video / audio signal processing unit 48 to the video tape T. The regeneration operation is performed.

By such a reproducing operation, when a control pulse corresponding to '5147' recorded in the information recording area of the video tape T is read by the signal recording / reading unit 46 and applied to the control unit 12, The controller 12 recognizes the unique number of the video tape T based on the control pulse (step 62), and then determines whether the corresponding number has been stored in the database 34 (step 64).

As a result of the determination, if the unique number read out from the video tape T is not the unique number stored in the database 34 (NO in step 64), the control unit 12 newly transmits the corresponding unique number to the database 34. After storing (step 66), the playback operation is normally performed on the videotape T (step 58), while the unique number read out from the videotape T is stored in the database 34. If the number matches (YES in step 64), the control unit 12 applies a predetermined control signal to the OSD processing unit 16 and the image signal processing unit 30 to display the OSD as shown in FIG. 4 on a CRT. A message such as '* This videotape is the videotape you have watched. * Press the play button if you want to watch again' (step 70).

Then, the control unit 12 determines whether the playback mode has been reset based on the playback key signal input from the control signal input unit 10 (step 72). In this process, the user selects the video tape T. If the playback mode is reset in the control unit 12 by operating the playback key configured on the control signal input unit 10 for re-viewing (YES in step 72), the control unit 12 proceeds to step 68 where the The playback operation is normally performed on the video tape T.

On the contrary, if the regeneration mode is not reset (NO in step 72), the control unit 12 determines whether the preset time has elapsed (step 74), and if the elapsed state of the preset time is not determined as a result of the determination, (NO in step 74), the control section 12 proceeds to the step 72, while if the preset time has elapsed while the playback mode is not set (YES in step 74), the control section 12 enters such a state. It is determined that the user has invalidated the viewing of the video tape T, and a predetermined control signal is applied to the tape driving mechanism 44 and the signal recording / reading unit 46, thereby providing the video tape T. The video recording T is ejected after the reproducing operation is stopped.

That is, according to the embodiment of the present invention as described above, according to the televideo with the playback record confirmation function of the videotape, when the user plays the videotape T, the videotape T watched the videotape. An OSD message indicating the tape (T) is output on the CRT screen, and in response to the OSD message, when the user operates the play button, the video tape (T) is displayed on the video tape (T) despite being the video tape (T) watched. If the playback operation is not performed by the user and the playback button is not operated by the user, the video tape T is ejected so that the playback operation on the video tape T is not performed.

As described above, according to a tele video having a playback record checking function of a video tape according to an embodiment of the present invention, a video tape is output through a OSD message outputted on a CRT when a user plays a specific video tape T. There is an advantage that the reproduction recording of (T) can be easily confirmed.
