1 Introduction
1.1 Product Description
The AL37204 Video Processor EVB is an evaluation product that demonstrates a
total solution for video surveillance applications using Averlogic IC chips. This EVB
product receives video streams from up to 4 cameras to be processed and shown on
a monitor in a variety of convenient display formats.
The main components include one video decoder (AL244) for processing 4 channels
of analog video inputs, one video decoder (AL240) for analog to digital conversion for
video playback input, and one video processor (AL37204). It is a low-cost, easy
solution for real-time video surveillance applications that use 4-channel video output
to TV monitors, VCRs and digital storage devices.
The AL37204 provides four analog CVBS video input connectors. It has cost-
effective, high-quality NTSC/PAL video decoding technology with adaptive comb-filter
Y/C separation processing and quad video processing. It is also equipped with BCS
(Brightness, Contrast, Saturation and Hue) control, Scale Down Function, Re-play
function, Zoom, Freeze, Internal OSD overlay, Motion Detection and PIP/POP display
capabilities for monitoring and controlling video surveillance devices.

2 Quick Setup
2.1 Attach power cable
The power adapter unit itself will be attached to the
Plexiglas. Attach one end of the power cable to the
adapter and the other end to a wall socket with the
appropriate voltage.
2.2 Attach TV monitor (requires CVBS w/ RCA connector)
Attach your monitor to the J2 connector, located near
the power adapter. Turn on your monitor.
2.3 Attach camera (requires CVBS w/ RCA connector)
Attach your camera to one of the four video input
connectors on the rear panel located on the right-
most side of the panel. Turn on the camera and
begin transmitting a picture.
2.4 Turn on board power
After you turn on your camera and TV monitor, toggle the
power switch (sw2), which is located on the main board
near the power adapter connector. The green LED, D5,
will illuminate. If it does not, check the power supply
connections.
Your monitor should display the picture that your
camera is transmitting. If it is not displaying the
video, your connections may not be secure or your
camera may be setup with the wrong standard (PAL
or NTSC), for which you will need to review the
configuration section below.

3.3 Keypad Panel
The Keypad Panel comes connected to the Main Board
with a ribbon cable. It contains 8 buttons, 9 LEDs and an
IR sensor. The LED 9 illuminates when power is supplied
to the board. The other LEDs (1-8) illuminate when the
corresponding buttons above them are depressed. The
buttons are used to manipulate the screen display and configure options
pertaining to information on the screen.
The functions on the panel buttons correspond to the diagram shown below.
A remote control is also supplied with the package
and can be used instead of pressing buttons on
the Keypad panel. The labeled remote control
buttons, located on the diagram to the right,
correspond to the buttons shown above and are
the only functional buttons used with this board.
The other buttons are disabled and non-functional.
