Multiprogram video tape recording and reproducing device

DETAILED DESCRIPTION The object of the present invention is to provide a VTR which is designed to simultaneously record and reproduce a multiple number of TV signals or programs.
To achieve the object and in accordance with the purpose of the present invention, as embodied and broadly described herein, according to a first embodiment of the present invention, a VTR includes a write head for writing an input recording signal on a video tape, an input recording signal mixing circuit having a rewritable storage circuit for storing first and second input recording signals, an output switching circuit for switching between the first and second input recording signals read out from the storage circuit to feed a selected one of the first and second input recording signals to a read head, and a control circuit for generating a read control signal for controlling the reading of the second input recording signal from the storage circuit in synchronism with the reading of the first input recording signal and for generating a switching control signal for controlling the switching operation of the output switching circuit for each field of the first input recording signal.
According to a second embodiment of the present invention, a VTR includes a read head for reproducing first and second input recording signals alternatively recorded on a recording medium for each field, a reproducing signal separating circuit having a circuit for identification of the reproducing first and second recording signals, a rewritable storage circuit for storing a selected one of the reproducing first and second signals for each field, an output switching circuit for feeding the reproducing signals repeatedly read out from the storage circuit, and a control circuit for generating a write control signal to control the writing in the storage circuit in synchronism with the reproducing signals, for generating a read control signal to control the reading of the reproducing signals from the storage circuit and for generating a switching control signal to control the switching operation of the output switching circuit depending on mixing or non-mixing state of the reproducing signals
