ABSTRACT:
A digested video signal producing device for producing digested video signals from the original video signals recorded the video tape includes a Read/Write head for reading the recorded video video sinal, a tape winding unit for positioning the video tape to predetermined recording positions with respect to the Read/Write head, a reproduction circuit for reproducing the original video signal, a decimating circuit for producing a digested signal by sampling the reproduced original video signal every other predetermined even number of fields, a storage circuit for storing thus obtained digested video signals, and a control unit for control overall operation of the device. When producing the digested video signal, the video tape is positioned to the first recording area where the original video signals are recorded. Sampled digested video signals are repeatedly stored in the storage circuit until the storage circuit is full. Then the video tape is rewound to a second recording area for recording thus obtained digested video signals.
