xi LD Facts and Features
Extron’s Sentosaxi LQ and Lanciaxi LD are high resolution, digital
video devices which convert interlaced video into non-interlaced
video. The Sentosaxi LQ and Lanciaxi LD convert the two field
frame into a single non-interlaced frame consisting of 1,050 lines
(LQ) and 525 lines (LD) producing a brighter, higher resolution
picture. The additional lines provide more light output and make
the overall image brighter.
The Sentosaxi and Lanciaxi each have a high quality three-line
adaptive comb filter that eliminates most of the chroma noise
found in standard composite video signals. In addition, an internal
TBC (Time Base Corrector) actually cleans-up low quality video-
tape signal noise (common to VHS tape players) for a more stable
and sharper image. Motion mode compensation virtually
eliminates the “jaggies” commonly found on video line quadruplers
and line doublers so that the image is smoother.
The Sentosaxi LQ and Lanciaxi LD include an internal two input
switcher - one S-Video and one composite video input are front
panel selectable, remote selectable as well as auto-switchable.
With the use of a high quality quad-standard decoder the
Sentosaxi LQ and Lanciaxi LD are compatible with all international
video formats including NTSC 3.58, NTSC 4.43, PAL and SECAM.

• Line quadrupler - Quadruples the resolution of standard video
from 525 lines at 15 kHz to 1050 non-interlaced lines at 63 kHz for
a clearer brighter output.
• Demo-mode - Built-in “demo mode” allows a triple-split screen of
video, line doubled and line quadrupled video side by side.
