Abstract

PURPOSE:To complete the recording at a commercial time zone and to reproduce a magnetic tape by displaying the elapsed time on the screen of a television receiver when the input to the television receiver is switched from the tuner circuit to the reproducing side. CONSTITUTION:When a changeover switch 4 is switched to the tuner circuit 2 and a broadcast program in on-air is viewed, the commercial time zone is incoming. In this case, in switching the changeover switch 4 to the reproducing circuit 6, a changeover switch 14a is switched at the same time and a counter circuit 14 is triggered. As a result, the count of the elapsed time by the counter circuit 14 is started and an encode circuit 15 encodes the count output into a video signal required for the on-screen display. The encoded video signal is added to the output of the reproducing circuit 6 by an adder circuit 12, then a picture with the elapsed time at a part of a reproduced picture is displayed on the screen on the television receiver 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic recording and reproducing apparatus capable of reproducing recorded magnetic tape during commercial hours.

[Prior Art] A magnetic recording/reproducing device 1 shown in FIG. 2 has a built-in tuner circuit 2, and a broadcast program selected by the tuner circuit 2 is supplied to a recording circuit 3,
is supplied to the television receiver 5 via. The changeover switch 4 selectively connects one of the tuner circuit 2 and the playback circuit 6 to the video output terminal 1a, and when watching a broadcast program currently on air, the changeover switch 4 is naturally connected to the tuner circuit 2 side. Can be switched.

Switching between recording a signal on the magnetic tape 7 or reproducing a signal from the magnetic tape 7 is done by a changeover switch 8, and the rotating magnetic bed 9 connected to the changeover switch 8 is switched to the recording circuit 3 side or the reproduction circuit 6 side. Change.

[Problems to be Solved by the Invention] The conventional magnetic recording and reproducing device 1 described above has, for example, when the changeover switch 4 is switched to the tuner circuit 2 side and a broadcast program is being displayed on the television receiver FI5. If the changeover switch 4 is switched to the playback circuit 6 side at the same time as a commercial starts, the player may continue to watch the playback image even though the commercial time has ended, which may cause him to miss a part of the program he really wants to watch. There were some problems.

[Means for Solving the Problems] The present invention solves the above problems, and provides a magnetic recording/playback device in which a tuner circuit and a playback circuit are selectively connected to a video output terminal via a changeover switch. There it is,
an adder circuit provided between the changeover switch and the video output terminal; and an on-screen timer connected to the adder circuit that operates when the changeover switch is switched to the playback circuit side and supplies a video signal indicating elapsed time. The gist of the invention is that it is configured by providing a circuit.

[Function] This invention displays the elapsed time on the screen of the television receiver when the video output terminal is switched from the tuner circuit side to the playback circuit side and is effectively used for playing back recorded tapes only during commercial hours. do.

[Example] Hereinafter, an example of the present invention will be described with reference to FIG. 1. FIG. 1 is a schematic circuit diagram showing an embodiment of the magnetic recording and reproducing apparatus of the present invention.

In FIG. 1, a magnetic recording/reproducing device 11 has a configuration in which an adder circuit 12 is provided between the changeover switch 4 and the video output terminal 1a, and an on-screen timer circuit 13 is connected to the adder circuit 12. The on-screen timer circuit 13 includes a counter circuit 14 and an encode circuit 15.

In the counter circuit 14, a changeover switch 14a interlocked with the changeover switch 4 is connected to a trigger input terminal, and when the changeover switch 4 is switched to the reproduction circuit 6 side, the counter circuit 14 counts the elapsed time. Start. The encode circuit 15 is the counter circuit 14
The counting output is encoded into a video signal necessary for on-screen display and supplied to the adder circuit 12.

Now, the changeover switch 4 is on the tuner circuit 2 side.
Suppose that the switch is switched to □ and you are watching a broadcast program on air when a commercial period arrives.

In this case, when the changeover switch 4 is switched to the reproduction circuit 6 side, the changeover switch 14a is simultaneously switched and the counter circuit 14 is triggered. As a result, the counter circuit 14 starts counting the elapsed time, and the encoding circuit 15 encodes the counting output into a video signal necessary for on-screen display.

The encoded video signal is added to the output of the reproduction circuit 6 by the addition circuit 12, so that an image with the elapsed time displayed on a part of the reproduced video is displayed on the screen of the television receiver 5. .

Therefore, the viewer can estimate the end of the commercial period from the elapsed time displayed on the screen, and by switching the selector switch 4 again to the tuner circuit 2 side, the viewer can partially watch the broadcast program that was interrupted by the commercial. You can watch it without missing anything.

In this way, the magnetic recording/playback device 11 has a configuration that displays the elapsed time on the screen of the television receiver 5 when the input of the television receiver 5 is switched from the tuner circuit 2 side to the playback circuit 6 side. Therefore, when broadcast waves are being supplied to the television receiver 5 via the tuner circuit 2, the elapsed time displayed on the screen is displayed during the commercial period, and the recorded video and video are compared. Therefore, you can skip only the commercials and enjoy your favorite video during the commercial period, and by stopping playback when the commercial is over, you can watch the broadcast program you were watching until then. You can continue watching without missing anything.

[Effects of the Invention] As explained above, according to the present invention, when the input of the television receiver is switched from the tuner circuit side to the playback circuit side, the elapsed time is displayed on the screen of the television receiver. Therefore, when broadcast waves are being supplied to the television receiver via the tuner circuit, the pre-recorded video can be displayed while watching the elapsed time displayed on the screen while the commercial is being played. is possible,
Therefore, you can skip only the commercials and enjoy your favorite video during the commercial period.Moreover, by stopping playback when the commercials are over, you can easily watch the broadcast program you were watching until then. It has excellent effects such as being able to continue viewing without interruption.
