The PROZONIC (Progressive Scan-Zoom and Noise) IC converts to a digital signal from the PICNIC,
which is a 15734 NTSC digital signal to a Progressive Scan digital signal at 31468 Hz. ICs 7714 and
7715 are Memory ICs, which store the video fields as they are being processed by 7708. The two
fields are recombined in the Line Memory inside 7708. The digital 480P signal is then output to a triple
DAC (Digital-to-Analog Converter) in IC 7611. The analog signal is then filtered and then output as
YUV on Pins 12, 14, and 15.
Horizontal and Vertical sync is output on Pins 18 and 19. The output on Pins 12, 14, and 15 is a 480P
analog signal.
