ADJUSTMENT ]
(EXAMPLE 2)
Following 3 timings are memorized in AUTO CHANNEL (CH 0) and 2 timings are memo-
rized in ENHANCED CHANNEL (CH 1 and CH 2).
AUTO
CH 0 T1 (fH = 31.5 kHz, fv = 60 Hz, H sync. pol=-, V sync. pol= - )
CHANNEL
T2 (fH = 48
.-
·kHz, fv = 60 Hz, H sync. pol=-, V sync. pol= - )
T3 (fH = 64
kHz, fv = 60 Hz, H sync. pol=-, V sync. pol=-)
ENHANCED: CH 1 T4 (fH = 30.5 kHz, fv = 70 Hz, H sync. pol=-, V sync. pol=-)
CHANNEL
T5 (fH = 48
kHz, fv = 60 Hz, H sync. pol=+, V sync. pol=+)
WHAT PICTURE COMES OUT?
When CH 1 (ENHANCED CH) is selected, relationship between input signal and memoriz-
ed timing is as follows.
Frequency and Polarity of horizontal
and vertical input sync. signal.
Memorized Timing correspond
to input signal.
