About the Lanciaxi xi xi xi xi
The Extron Lanciaxi video scan line doubler (figure 1) is a high
resolution, digital video device that converts interlaced video
into non-interlaced video. The Lanciaxi converts the two field
frame into a single non-interlaced frame consisting of 525 lines,
producing a brighter, higher resolution picture. The additional
lines provide more light output and make the overall image
brighter.

Figure 1 — A typical Lanciaxi xi xi xi xi application
The Lanciaxi has 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 time base
corrector (TBC) cleans-up low quality videotape 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 doublers so that the
image is smoother.
The Lanciaxi includes an internal two input switcher — one
S-video input and one composite video input are front panel
selectable, remote selectable, and auto-switchable. A quad-
standard decoder makes the Lanciaxi compatible with all
international video formats: NTSC 3.58, NTSC 4.43, PAL, and
SECAM.
Features
• Line doubler — Doubles the resolution of standard video
from 525 interlaced lines at 15 kHz to 525 non-interlaced
lines at 31.5 kHz for a clearer, brighter output.
• Demo-mode — Built-in demo mode allows split screen of
video and line doubled video side by side.
