Abstract

The video recording and reproducing apparatus can record and play back regardless of the applied television broadcasting system. An image recording and reproducing apparatus including an image recording and reproducing unit capable of recording and reproducing in a single broadcast mode for this purpose; A broadcasting method converter for processing the applied video signal to be converted into a video signal of a desired broadcasting method; Command applying means for applying information on the desired broadcasting method; A control unit for designating a method to be converted into the broadcast mode converter based on the information output from the command application unit; First selection means controlled by the control unit to control to selectively apply the applied video signal and the signal output from the video recording / reproducing unit to the broadcasting type converter; Second selection means controlled by the control unit for controlling to selectively apply the signal output from the broadcast mode converter and the applied video signal to the video recording / reproducing section; And third selecting means for controlling to be selectively applied to the signal output from the video recording / reproducing section and the signal output from the broadcasting format converter controlled by the control section. Therefore, the circuit can be simplified, and various television signals can be recorded and reproduced without any change in a circuit for recording and reproducing an existing video signal.

Claims (4)

An image recording and reproducing apparatus having an image recording and reproducing section 40 capable of recording and reproducing in a single broadcasting mode; A broadcast method converter 30 for processing the applied video signal to be converted into a video signal of a desired broadcast method; Command applying means (10) for applying information on the desired broadcasting method; A control unit 20 for designating a method to be converted into the broadcasting method converter 30 based on the information output from the command application means 10; First selection means (SW1) for controlling to be applied by the control unit 20 to selectively apply the video signal to be applied and the signal output from the video recording and playback section 40 to the broadcast method converter (30) ; Second selection means (SW2) controlled by the control unit 20 to control the signal output from the broadcast format converter 30 and the applied video signal to be selectively applied to the video recording / reproducing section 40; ; And third selection means for controlling to be applied by a control unit 20 so that the signal output from the video recording / reproducing unit 40 and the signal output from the broadcast mode converter 30 are applied to the selection jug. And a video recording and reproducing apparatus (SW3). A video recording and reproducing apparatus including a video recording and reproducing section 40 capable of recording and playing back a video signal applied by a single broadcasting method, and a broadcasting method converter 30 for converting an incoming video signal into a desired form. An image recording and reproducing method for recording and reproducing the broadcast method; When the video recording and reproducing apparatus is set to the recording mode, a first broadcasting method difference determination process for determining whether the broadcasting method of the applied video signal and the single broadcasting method set in the video recording and playback unit 40 are different. A first broadcast method conversion process of converting the applied video signal into the single broadcast method when the applied video signal is different from the single broadcast method as a result determined in the process of determining whether the first broadcast method differs; A recording process of applying to the video recording / reproducing unit 40 to record the video signal when the video signal is changed in the conversion process; If the video signal recording and reproducing apparatus is set to the reproducing mode, a second broadcasting method judging process for judging whether or not the single broadcasting method set in the video recording and reproducing unit 40 and the broadcasting method processed by the output device are different. A second broadcast method conversion process of converting a broadcast method of a signal reproduced by the video recording / reproducing unit 40, and a signal output from the second broadcast method conversion process And a reproducing process of reproducing to the output device. The method according to claim 2, wherein the video signal recording and reproducing method is determined in the process of determining whether the first broadcasting method differs, when the applied video signal and the single broadcasting system set by the video recording / reproducing unit 40 are the same. And a transfer control process of transferring the broadcast signal of the video signal directly to the video recording and reproducing unit (40). The method of claim 2, wherein the video signal recording and reproducing method is the same as the signal reproduced by the video recording and reproducing unit 40 and the broadcasting method set in the output device as a result of the determination in the second broadcast method difference determination process. And a transfer control process of directly transferring the signal output from the image recording and reproducing unit (40) without converting it. ※ Note: The disclosure is based on the initial application.
