Operation
Sentosa xi xixi xixi
The Sentosa xi LQ converts interlaced video to non-interlaced
video with four times the original number of horizontal scan lines.
For NTSC 3.58/NTSC 4.43 video, each field of 262.5 lines is
quadrupled to create a 1050 line non-interlaced screen scan. The
same process applies to PAL/SECAM video, except the field
consists of 312.5 horizontal lines which, when quadrupled,
becomes 1250 horizontal lines/screen. The Sentosa
xi output
horizontal scan frequency is 63 kHZ NTSC 3.58/NTSC 4.43 and
62.5 kHZ PAL/SECAM while vertical scan remains 60 HZ for
NTSC 3.58/NTSC 4.43 and 50 HZ for PAL/SECAM.
Lancia xi xixi xixi
The Lancia xi LD converts interlaced video to non-interlaced video
with double the original number of horizontal lines. For NTSC
3.58/NTSC 4.43 video, each field of 262.5 lines is doubled to
create a 525 line non-interlaced screen scan. The same process
applies to PAL/SECAM video, except the field consists of 312.5
horizontal lines which, when doubled, becomes 625 horizontal
lines/screen scan. The Lancia
xi output horizontal scan frequency
is 31.5 kHZ NTSC 3.58/NTSC 4.43 and 31.25 kHZ PAL/SECAM
while vertical scan remains 60 HZ for NTSC 3.58/NTSC 4.43 and
50 HZ for PAL/SECAM.
_ One exception to the above Lancia xi description occurs when the
VGA DIP switch on the Lancia xi rear panel is in the enable position.
This results in a 480, non-interlaced, horizontal line screen scan
regardless of the input type.
