ABSTRACT:
A video tape recorder having provisions for erasing a desired fraction of each frame of a composite picture signal on a magnetic tape and for recording substitute picture information on the erased fractions, thereby making it possible to split the screen into two windows for the simultaneous display of different images. Included is a window size input device to be operated upon by the user for specifying a desired fraction of each frame of the composite picture signal recorded on the tape. A frame fraction signal generator circuit responds to the output from the window size input device, as well as to horizontal and vertical sync pulses derived from the composite picture signal being reconstructed from the tape, for generating a frame fraction signal indicative in real time of the specified fraction of each frame of the composite picture signal to be erased from the tape. A mode-setting circuit responds to the frame fraction signal for connecting an erase oscillator to a pair of video transducers thereby causing erasure of the specified fraction of each frame of the composite picture signal on the tape. The mode-setting circuit also responds to the frame fraction signal for permitting substitute picture information to be recorded at the erased fractions of the prerecorded picture signal on the tape.
