Embodiment Construction

[0012] The operation description of the system shown in accompanying drawing 1 is as follows:

[0013] First, if certain data, which is necessary for recording a video signal output from an external device onto a magnetic tape loaded in the second deck, is input through a control panel (not shown), the switch of the second switch system 40 SW1 and SW2 are switched in accordance with the level of the first control signal COPY-CON output from the first deck system controller 12 (for example, “low” state). Then, the recording luminance and color signal (REC-FM or REC-COLOR) output from the luminance / chrominance signal processor 60 is selected by switches SW1 and SW2, and then supplied to the recording signal processor 20 of the second deck.

[0014] Here, the recording luminance and color signal is a signal responsive to a composite sync signal (VIDEO IN) applied to the luminance / chrominance signal processor 60 from an external device (not shown). Therefore, a video signal outpu...

Abstract

Disclosed is a double-videocassette recorder, comprising a first and a second servo systems used to output display-mode control signals, a first deck pick-up signal processor used to process pick-up signals provided by the display head of the first deck to output brightness and color signals, a second deck pick-up signal processor used to process the pick-up signals provided by the display head of the second deck to output brightness and color signals, a second deck recording signal processor used to process recording brightness and color signals so as to provide the processed signals to the recording head of the second deck, a brightness / color signal processor used to demodulate the displaying brightness and color signals to output and compose video signals.

Description

Technical field: [0001] The invention relates to a dual-card video recorder, in particular to a dual-card video recorder with a brightness / chromaticity signal processor. Background technique [0002] A dual-cassette VTR typically includes a pair of luma / chroma processors, one for processing the signal from each deck or the composite video signal applied from an external device. However, with this dual-cassette recorder, since it is rare to operate (play or record) two tapes at the same time, each deck is loaded with only one tape, so at any given time, there is usually only one processing tape. device is running. Therefore, if the playback and recording functions of each deck are performed by only one luma / chroma processor, the production cost of manufacturing the device can be reduced. Contents of the invention [0003] The object of the present invention is to provide a dual-cassette video recorder which utilizes one luminance / chrominance signal processor to perform th...
