Operation

Sentosa

xixi

The Sentosaxi 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 Sentosaxi 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

xixi

The Lanciaxi 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 Lanciaxi 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

description occurs when the

VGA DIP switch on the Lancia

rear panel is in the enable position.

This results in a 480, non-interlaced, horizontal line screen scan

regardless of the input type.
