ABSTRACT:
A double-deck videocassette recorder (VCR) requires only one luminance/chrominance signal processor, rather than the two which are conventionally necessary for a double-deck VCR. The first deck has only a pickup head, whereas the second deck has both pickup and record heads. A first switching unit selects playback mode control signals from either the first deck servo or the second deck servo, to be provided to the single to the luminance/chrominance signal processor. The first switching unit also selects playback control signals from either the first deck system controller or the second deck system controller, to be provided to the single to the luminance/chrominance signal processor. A second switching unit selects either the luminance and color signals which are being played back from the first deck pickup head, or the luminance and color signals provided from the single luminance/chrominance processor, to be supplied to the second deck recording signal processor for recording on a tape using the second deck record head. A third switching unit selects between playback luminance and color signals supplied from the pickup heads of each deck for provision to the single luminance/chrominance signal processor. Each of the first, second and third switching units are under control of the first deck system controller. The first and second deck system controllers also control the servo systems for their respective decks.
