ABOUT THE MUX-1602C
The XtendLan MUX-1602C multiplexer represents the latest
advance in digital picture processors. It lets you record pictures
from
multiple video cameras while simultaneously displaying one or
more
cameras.
The time-lapse VCR is a proven and valuable tool for document-
ing visual events captured by a single camera. Applications em-
ploying multiple cameras require additional VCRs, sequential video
switchers or quad picture processors. Each solution has tradeoffs.
The VCR is an expensive piece of equipment which requires main-
tenance. The video switcher reduces the rate at which each camera
is recorded. The quad picture processor reduces the quality of the
recorded image. For many applications, none of these solutions is
satisfactory. MUX-1602C multiplexers address the requirement to
view
and record multiple cameras through the application of digital
video
multiplexing, Dynamic Time Division (DTD) and Vertical
Interval
Signal (VIS) technology.
Using proprietary DTD technology, MUX-1602C multiplexers
continuously analyze the motion content of all camera pictures.
They determine camera priority based on picture activity and
output pictures to the screen and to tape. Maximum efficiency is
achieved by
dedicating greater recording time to those cameras
at which activity is detected. VIS technology is employed to code
every picture
sent to the VCR with the camera number, camera
name, alarm
status, time and date.
Each MUX-1602C multiplexer displays camera pictures on screen in
one
of several selectable formats: full-screen, Picture-In-Picture
(PIP), 2x roving zoom, 2
x
2 pictures, 3
x
3 pictures. All formats are
available while viewing
live or taped pictures. During tape playback,
pictures are displayed
with full screen quality in the selected
format. Pictures have 512
x
464 (512
x
512 PAL) resolution, up to
256 gray levels and 16million colors.
