Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated system of an audio tape recorder and a video tape recorder.
VTR), an audio tape recorder and a radio tuning circuit are built in one housing, and they can be used independently according to the user's choice, and the audio signal can be dubbed to a video cassette tape. And a video tape recorder integrated system.

[0002]

2. Description of the Related Art Generally, a VTR and an audio tape recorder are separate devices and are housed in separate housings. A television tuning circuit is built in the VTR housing, and a radio tuning circuit is built in the audio tape recorder housing. The VTR and the audio tape recorder are built in the same housing together. What has been made has not been provided yet. Therefore, although the VTR system itself can receive a television broadcast and record / reproduce a video cassette tape, in addition to these functions, an audio signal reproduced by an audio tape or an audio signal of a radio tuning circuit can be recorded as a video. The function of dubbing the cassette tape could not be performed. At the same time, recently, VTRs and video cameras have become universal, and the demand for editing video cassette tapes has increased, and the demand for the user to edit software for dubbing an appropriate audio signal on the video screen or the edited video screen. Is being gradually increased.

[0003]

However, in the case of dubbing an audio signal to a video cassette tape, a VT capable of recording / reproducing the video cassette tape.
The R system and the audio tape recorder capable of reproducing the audio cassette tape are required respectively, and the signal lines of the VTR and the audio tape recorder must be accurately connected according to each input / output, which is extremely complicated. There was an inconvenience that it was. Similarly, when an audio signal of television broadcasting or VTR is recorded on an audio cassette tape,
A VTR capable of receiving television broadcasting and an audio tape recorder capable of recording on an audio cassette tape are required respectively, and the signal lines of these VTR and audio tape recorder are accurately connected according to each input / output. There was a disadvantage that it was complicated because it had to be done. In addition, when the user plays a video screen on the television monitor and tries to play an audio source different from the video screen through the speaker (for example, while receiving the video screen of the television, the separate video is received. Even when trying to listen to music played on a cassette tape, the current television and VT
There is a disadvantage that it cannot be realized only by the R system, a separate audio reproducing apparatus is required, and those signal lines must be accurately connected according to input / output.

In order to solve such a problem, the present inventors intend to provide the following integrated system of an audio tape recorder and a video tape recorder.

Then, the radio FM
The demodulation means 31 FM demodulates the radio audio signal and outputs it to the radio audio signal terminal 2 of the output audio signal selection means 14, the audio deck input selection means 12, and the VTR deck input selection means 11. Then, the user operates the VTR deck input selection means 11 to select one of the television broadcast signal, the radio audio signal and the reproduced audio signal of the audio deck 32 as the input signal of the VTR deck 23. You can In addition, the user can operate the audio deck input selection means 12 to select one of the radio audio signal, the television audio signal and the VTR reproduction signal as the input signal of the audio deck 32. Further, the user can operate the output video signal selecting means 13 to select one of the VTR video signal and the television video signal and output the selected one to the video signal output terminal 24. Further, the user operates the output audio signal selecting means 14 to output the television audio signal and the VT.
One of the R audio signal, the radio audio signal, and the reproduced audio signal can be selected as the output audio signal. In addition, the user can operate the audio output switching means 15 to output the audio signal selected by the output audio signal selecting means 14 to the audio signal output terminal 27 or the speaker 28. Therefore, the VTR deck 23 and the audio deck 32 can be used independently of each other, the video output of the monitor and the audio output can be selected from different sources, and the audio output can be output to the speaker. You can also That is, the following various functions can be performed according to the user's selection.

When the user wants to listen to the radio audio while watching the broadcast screen of the television, the output video signal selecting means 13 is short-circuited to the television video signal terminal 5 of the decoding means 25 to output the output. When the audio signal selection means 14 is short-circuited to the radio audio signal terminal 2, a television video signal and a radio audio signal are output. In addition, when the user wants to listen to the audio of the audio cassette tape while watching the television broadcast screen, the user sets the output video signal selecting means 13 to the decoding means 25.
If the output audio signal selecting means 14 is short-circuited to the reproduced audio signal terminal 3 while operating the audio deck 32 in the reproduction mode, the television video signal and the audio cassette tape are output. And the radio audio signal of are output. In addition, when the user wants to dubb a radio audio signal or a reproduced audio signal of the audio cassette tape to the video cassette tape separately from the output on the monitor side, the user needs to record the video signal on the VTR deck 23. After inserting the tape, the VTR deck input selecting means 11 is operated to select one of the radio audio signal and the reproduction audio signal of the audio cassette tape, and the VTR deck 23 is operated in the recording mode. The audio signal is dubbed. Similarly, when an audio signal is to be recorded on the audio cassette tape separately from the output on the monitor side, the audio cassette tape is inserted into the audio deck 32 and the audio deck input selection means 12 is operated to operate the radio audio. By selecting one of the signal, the VTR audio signal and the television audio signal and operating the audio deck 32 in the reproduction mode, the desired audio signal can be recorded on the audio cassette tape. Further, in the integrated system of the audio tape recorder and the video tape recorder according to the present invention, a plurality of various functions other than the exemplified functions can be performed by operating the selection means. And the present invention is a VTR
The audio deck and the audio deck are not limited to be housed in one housing, and a VTR video camera may be included and housed in the one housing.

[0012]

As described above, in the integrated system of the audio tape recorder and the video tape recorder according to the present invention, the VTR is provided in one housing.
Since the system, the radio tuning circuit, and the audio deck are built-in so that they can interface with each other, the radio audio signal and the audio tape reproduction signal can be audio dubbed onto the video tape by only a single system. Moreover, each VTR audio signal, television audio signal, radio audio signal, audio tape reproduction signal can be output to the monitor side while outputting the television image or VTR image signal to the monitor, and the VTR, radio, and audio deck. Since each can be selected and used independently, there is an effect that various functions can be easily performed using one system.
