Abstract

In an audio/video information recording/playback apparatus with repeating monitor function which includes an endless type recording medium T-1 of about twenty seconds for one cycle and a main recording medium T-2 with tape ends, while both media are driven simultaneously in a recording mode to record broadcasting or other external information, if a viewer wants to repeatedly monitor a part of this information, he can set the T-1 to a repeating playback mode by pushing a playback button of a remote control box and the desired part can be repeatedly played back for repeated monitoring by a TV set. During this playback of T-1, T-2 is continuously driven in the recording mode to continuously keep recording the information. Further, while the viewer is monitoring the playback of the T-2 of a VTR-2 by the TV set, if he wants to repeatedly monitor a part of the playback information, the VTR-2 is stopped by switching to a playback mode the T-1 of a VTR-1 which has already recorded the part of playback of VTR-2, so that this part can be repeatedly played back on VTR-1 for about twenty seconds so as to enable the viewer to learn well the part recorded. When the viewer finishes learning, he pushes a recording button again to switch the VTR-1 to the recording mode again, and then the VTR-2 is driven in the playback mode again from the stopping position. The VTR-1 is continuously driven to record repeatedly the playback information of the VTR-2.

Claims

1. An audio/video information recording/playback apparatus with repeating monitor function and having an input means for receiving broadcast information, comprising:

means for performing a repeating recording operation of an endless type recording medium (T-1) which is composed of at least several seconds per cycle, and for performing a repeating playback operation thereof selectively in response to a control signal;

means for performing a recording or playback operation of a main recording medium (T-2);

means responsive to a first control signal generated by a remote control box for driving both said recording media (T-1 and T-2) simultaneously in a recording mode; and

control circuit means including

(a) first means operative in a first mode that is responsive to a second control signal generated by said remote control box for recording on said main recording medium (T-2) broadcast information received at said input means while causing a repeating playback of said endless type recording medium (T-1) so as to keep recording said broadcast information on said main recording medium (T-2) without interruption; and

(b) second means operative in a second mode that is

(i) responsive to a third control signal generated by said remote control box for starting playback of said main recording medium (T-2) and, at the same time, setting said endless type recording medium (T-1) in the recording mode while said main recording medium (T-2) is used for playback so that information previously recorded by said main recording medium (T-2) can be recorded by said endless type recording medium (T-1),

(ii) responsive to a fourth control signal generated by said control box for causing temporary stopping of a driving operation of said main recording medium (T-2) at a temporary stopping position thereof while causing a repeating playback of said endless type recording medium (T-1), and

(iii) responsive to a fifth control signal generated by said remote control box for performing a playback operation of said main recording medium (T-2) from said temporary stopping position and at the same time switching said endless type recording medium (T-1) to the recording mode to record information previously recorded on said main recording medium (T-2).

2. An audio/video information recording/playback apparatus with repeating monitor function of claim 1, wherein said means for performing recording and playback operations on said endless type recording medium (T-1) and said main recording medium (T-2) comprise, respectively, first and second video tape recorders.

3. An audio video information recording/playback apparatus with repeating monitor function of claim 1, including a relay wherein broadcast information recorded on the endless type and main recording media can be selectively viewed on a television set by controlling said relay.

4. An audio video information recording/playback apparatus with repeating monitor function of claim 1, wherein the remote control box generates infrared rays.

5. An audio video information recording/playback apparatus with repeating monitor function of claim 4, wherein audio information for controlling said remote control box can be input separately through a microphone.

6. An audio video information recording/playback apparatus with repeating monitor function of claim 1, wherein video broadcast information is received by an antenna, the apparatus including a splitter for splitting the information to be received by the endless type and main recording media.
