Description for AUTO OFFSET and GET OFFSET:
The
“GET OFFSET”
can use to make the EEPROM copy by PE engineer. When the
PAL and NTSC geometry adjustment had finished, trigger the “GET OFFSET” from “0” to
“1” to store the geometry offset datum between PAL and NTSC in EEPROM.
On producing, these geometry offset datum can use to easy the NTSC geometry
adjustment. When finished the PAL geometry adjustment, trigger the “AUTO OFFSET”
from “0” to “1”, then the
geometry adjustment of NTSC signal will finish automated. If now
the geometry of NTSC signal is look good, it not needed to adjust the geometry of NTSC
signal any more.
