Chapter 1 General Information
1.1 Introduction
The DVP-7421BE is a high-end video capture board
with a hardware codec (simultaneous compression/
decompression, or encode/decode) engine. It supports
4-channel live preview, video/audio compression and
playback at D1 resolution and 120/100 fps. Up to four
DVP-7421BE boards can installed in one PC for
concurrent live viewing, compression and playback of
up to 16 channels at D1 resolution and 480/400 fps.
The programmer can use the comprehensive SDK to
load protection code or system parameters into the
on-board 128-byte EEPROM. The SDK comes with
sample code for reference. The hardware codec engine
makes the DVP-7421BE the ideal platform for
applications like network video servers, Video
conferencing and high-end digital video recorders.

1.2 Production Feature
The photo is the main interface of DVP-7421BE sample
program. The DVP-7421BE feature is like below：
A. EEPROM function ready product
Customer can write the value in EEPROM and check
the value before surveillance software boot up. System
Integrator can design protection to protect software
system. Valid offset values are between 0-127,Valid
output values are in the range of 0 and 255.
B. Full D1,real time,MPEG1/2/4,Video and
Stereo Audio Hardware Encode
The DVP-7421BE support the full D1 resolution, real
time (encode frame rate 30 fps). Moreover, the
DVP-7421BE can encode the stereo audio input to
MPEG1-LayerII format.
C. Full D1,real time,MPEG1/2/4,Video and
Stereo Audio Hardware Decode
Like encode model, the DVP-7421BE can decode D1
resolution, real time, and stereo audio out. The user
can easily playback the compression by the

8
DVP-7421BE hardware capability.
D. Software Decoder to AVI
The DVP-7421BE support software decode that can
convert compression MPEG file to AVI format (*.Divx).It
is convenient for customer integrate the function to their
software system.
E. GPIO access control
User can integrate the DI/DO device, like warning
alarm or IR sensor. The demo program can show and
feedback the signal information connection or not. It’s a
function good for SI combine various device to
establish powerful surveillance system.
F. Smart Quad Real-time Raw Data Preview
This special characteristic function can support the user
raw data to further advantage. For example, one can
use the function in the domain of intelligent analysis,
image comparison and optical Inspection, etc. The
Smart Quad raw data can provide the 4CIF video files
that combined in D1 resolution block. The customer
also can choices one of Quad to advance operation.
G. Hardware Motion Detection
The DVP-7421BE hardware support motion detection.
User can set nine areas to monitor the video changes.
The degree of changes could set by library code. It is a
benefit for software develops less effort on motion
function.

H. Video Configuration
The DVP-7421BE can configure the most feature of
video. User can set GOP frames, GOP type, Video
Format, Frame rate, Video Bit rate, Average Video Bit
Rate, Audio Bit rate, Audio Sampling rate, etc.
