Adjusting input video timing

The horizontal delay adjustment varies the timing of the input video relative to input
syncs and blanking in 10 bit mode whichever source is the active reference.

Mode

Input video timing

10 bit

8 bit

Relative to input video syncs and blanking

No horizontal delay available

Select position 9 (H del) with the SEL control to allow the shaft encoder to adjust the
input video timing with respect to the input video syncs in steps of 37ns. This adjustment
is available in 10 bit mode only.

Note:

The firmware version number is shown in 8 bit mode when SEL 9 is selected. Do not
leave the SEL switch in position 9 as it also used as a power-up factory reset function.

The available range is -128 to +127 steps (r- 4.5 microseconds) relative to the
factory default position. The value cannot be adjusted outside this range.

Setting 525 (NTSC) Setup

Use rotary switch (SEL) position 7 together with the shaft encoder in

525

(

NTSC)

mode

ONLY

to switch Setup (pedestal) compensation ON or OFF.

Display Text

Description

Setup on

7.5 IRE subtracted from black level, gain increased

Setup off

Black level and gain settings assume no 7.5 IRE offset

Note:

When the board is in 525 line (NTSC) mode, the shaft encoder can be used to switch
setup (pedestal) compensation on and off.
When setup compensation is ON the display will show “setup on”. The 7.5 IRE offset
will be subtracted from the black level and the gain will be increased to compensate.
This does not affect the Y Gain and Y Offset settings.
When setup compensation is OFF the display will show “setup off”. The black level and
gain will be set assuming no 7.5 IRE offset, in the same way as for PAL inputs.
The setup mode is preserved through 625-line operation and power down.

Restoring factory defaults

If required all settings can be returned to default values. This is done by powering the
module with rotary switch (SEL) in position 9 and piano switch lever 4 UP. The display
text will be 'DEFAULTS?' To restore default settings set piano switch lever 4 DOWN.

Note:

Moving the rotary switch away from position 9 will set the board to normal operation
without overwriting the previous settings.
On no account should the SEL switch be left in position 9.
