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
continu
ously analyze the motion content of all camera pictures.
They de
termine camera priority based on picture activity and
output pic
tures 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 16
million colors.

TECHNICAL OVERVIEW
Video Input and Output
The MUX-1602C is available configured for either the
NTSC/EIA or
PAL/CCIR video standard. The units feature video
camera inputs
with a passive looping output for each. Camera
input termination
is programmable via an on-screen menu. Synchronization or
phasing of cameras is not required.
Video recording and playback is supported by VCR connections
for both composite and S-Video signal formats. The MUX-
1602C
automatically determines the format used during tape
playback.
Two monitor outputs allow viewing of live camera or videotaped
pictures on standard monitors. The Main Monitor displays selected
cameras in any available display format. The Call Monitor displays
live camera images full screen, including images from alarm cameras.
Motion Detection
The MUX-1602C continuously monitors all camera inputs for
motion.
When motion is detected, the MUX-1602C increases the
frequency with
which that camera is recorded and displayed. In this
way, recording
and display time are dynamically allocated
according to the scene
activity. Motion sensitivity for each
camera input can be set via a
16 x 12 target graphic overlay. Targets can be turned on or off as
required. Target sensitivity is fixed.
Video Display
The MUX-1602C monitor displays live camera pictures or
pictures
recalled from tape. The display is based on a 512 x
512 x 16 bit
digital video memory containing two interlaced
video images. As
many as 256 gray shades and 16 million colors
can be displayed in
six screen formats including full screen, 2x
zoom, Picture-In-
Picture (PIP), 2 x 2, 3 x 3 and 4 x 4.
Color demodulation is based on luminance and color difference
processing. Demodulation circuitry operates on a line by line basis
and will correctly demodulate the chroma information in video
conforming to either the NTSC or PAL standard unless horizontal
sync cannot be correctly detected.
A graphic generator with two interlaced bit-mapped pages provides
the alphanumeric and graphic overlays required for on-screen
menus, camera titles and system messages.

Installation and Operation Manual 3
Encoder Output
The video encoder produces a single video signal containing field
by field samples from all camera inputs. The signal is provided in
both composite and S-Video formats for connection to a video
recorder. Encoder operation is continuous and independent of
display and decoder functions. All inputs are sampled in camera
number order until motion is detected, when sampling is weighted
in favor of the active cameras.
The encoder uses Vertical Interval Signaling (VIS) techniques to
encode system information onto video output to the VCR. Time,
date, camera title, camera number, and alarm status information
are placed on the 16 horizontal lines preceding the first active video
line. This technique can improve vertical sync recovery and can
also eliminate the degraded graphics associated with poor tape
recorder performance.
Decoder Output
The video decoder processes the video output by the VCR during
playback, recovering the video from each camera originally
recorded. The decoder digitizes the playback video and recovers
the VIS information encoded onto each field. If the recovered
field is to be displayed, it is written to the video display memory.
