d) AUTO PLL SETUP
Sets enable/disable of automatic execution of the
PIXEL ADJUST function.
ON
: When the AUTO PLL SETUP is set to ON, the
PIXEL ADJUST is automatically executed
when the main power is turned on or when the
input signal is switched. (Be noted that about
10 seconds are required to output the video
signal after switching the input signal when this
function is kept to the ON position.)
OFF
: The automatic PIXEL ADJUST is executed
only when AUTO item of the user menu
PIXEL ADJUST is activated.
This function becomes valid only when the signal that
enables the PIXEL ADJUST is inputted to the PFM-
500A3W/510A2W.
Set the AUTO PLL SETUP item to the OFF position
normally.
e)
AUTO PLL PIXEL
Selects the functions that are automatically adjusted
when PIXEL ADJUST is executed.
ON
: Both the TOTAL H PIXEL and DOT PHASE
are automatically adjusted.
OFF
: Only the DOT PHASE is automatically
adjusted.
In the case that the PFM-500A3W/510A2W is used
under the environment where input signal contains
much noise, there are cases that the PIXEL ADJUST
mis-operations. Therefore, set the AUTO PLL PIXEL
to the OFF position. In such a case, the TOTAL H
PIXEL can be adjusted only manually.
This function becomes valid only when the signal that
enables the PIXEL ADJUST is inputted to the PFM-
500A3W/510A2W.
Set the AUTO PLL PIXEL item to the ON position
normally.
f)
H/V SHIFT
Selects the method to control the horizontal and
vertical picture shift.
EDGE : When EDGE is selected, a picture is shifted
by changing the starting position when
reading data into memory. Using this
function, the entire area including blanking of
all pictures can be displayed by shifting. The
variable range of shifting is 1 horizontal and
vertical period respectively.
CAPT : When CAPT is selected, the picture that is
already written into memory is shifted by a
scan converter. Using this function, a picture
can be shifted as much as
±
50 % of a
picture. When a picture is partly lacked at an
end of a picture, the lacked portion of a
picture cannot be displayed.
Set the H/V SHIFT item to the EDGE position normal-
ly.
g) VIDEO SHARP SW
Sets analog aperture ON or OFF.
The two methods are used for the aperture correction
of the video signals (NTSC/PAL/SECAM/NTSC4.43/
PAL60 and YUV signal having horizontal frequency
of 15 kHz). These two methods are the scaling filter
and the analog aperture of the scan converter.
ON
: Both the scaling filter and the analog aperture
of the scan converter are used for aperture
correction.
OFF
: Only the scaling of the scan converter is used
for aperture correction.
This function becomes valid only when the signal
(NTSC/PAL/SECAM/NTSC4.43/PAL60 and YUV
signal having horizontal frequency of 15 kHz) is
inputted to the PFM-500A3W/510A2W.
Set the VIDEO SHARP SW item to the ON position
normally.
h) AUTO FT CANCEL
Sets the FT (field tearing) cancel circuit ON or OFF.
The PFM-500A3W/510A2W has the FT (field tearing)
prevention circuit caused by the overrun of memory
while it is displaying the moving picture (video and
DTV). However, there can be cases that noise appears
on screen when the FT (field tearing) prevention is
being executed.
ON
: The FT (field tearing) is cancelled in every
picture size and in every shift conditions as
long as the PFM-500A3W/510A2W is
receiving the moving picture. When this item
is set to ON, noise may appear only once
after the size/shift is adjusted. (Noise does
not last long but appears only once when the
size/shift adjustment is complete.)
OFF
: The FT (field tearing) cancel circuit is
disabled. When OFF is selected, there can be
a case that the FT (field tearing) appears on
screen depending on the adjustment condi-
tions of picture size/shift. However, the noise
due to operation of the processing circuit
does not occur.
Set the AUTO FT CANCEL item to the ON position
normally.
