Through years of video
experience (acquisition, processing, displaying, digital
or analog transmission means), MVD keeps on improving its
competence developing each time new solutions.
MVD has also a strong knowledge in fast digital
electronic, which one is exploited at its best through
Xilinx FPGA possibilities. |

What can MVD provide to you
?
MVD proposes expertise interventions right from
conception or at specification stages of the project. MVD
can help you to adopt the best suited solution such as
components to be implemented. After an expertise stage,
our engineers can develop your image solution. |

MVD proposes 3 ways of
development
1) Xilinx FPGA
Our staff can develop cabled processing inserted into
video set, which will result in nearly no delay.
MVD set up a functions library such as :
- Video standard generation (CCIR, STANAG, VESA)
- SDRAM controler for video buffers checking
- Change of color space
- Outlines detection
- Mono and bi-dimensional FIR filters
Acknowledgment of our know-how permits MVD to publish
different articles in Xilinx XCELL magazine and other
specialized journals, such as "Electronique"
magazine. Among the newest publications :
- Implementation of real time
histogram (
 125 kB)
- 9x9 200 Mpix/sec real time convolution on
VIRTEX-II architecture
Among our developments, we can quote 32 and 64 bits PCI
boards permitting to acquire and process images in real
time, at a 100 MB/sec pixel frequency.

2) XtremeDSP
Xilinx FPGA architectures allow very efficient
implementation of DSP functions Cores such as : FIR
filters, MAC, FFT, providing unprecedented level of
performance. |

3) Couple FPGA/DSP
FPGA/DSP is often used in signal processing
application. MVD engineers use the best of each
technology to determine cabled and software implemented
processing, according to carrying-out speed
requirement, costs and other important parameters
to considered design. Among our references, we can find VisionBooster II system,
one of our own products.
A demonstration VisionBooster IItest bench is set up in
MVD premises. |

Examples of MVD solutions
Acquisition system
Mainly conceived around CMOS sensors (Photobit, Kodak),
MVD develops cameras whose sensors permit cheap solutions
and small size conceptions.
MVD also proposes a flash for in one-shot video image
acquisition. |

|
|
|
|
|
| |
|
|
|
Signal transmission system
MVD proposes serial transmission systems development for
one or more digital videos on LVDS pairs. This system
makes possible a simultaneous transmission of 2 videos
set, their common clock and respective synchronization
signals on 2 LVDS pairs |
|
 |
|
|
|
|
|
|
|
| |
|
|
|
Video processing
We develop any system of video acquisition and direct
display on CRT or flat panel (TFT Express), incrustation,
mosaic display. MVD is also competitive on PC software,
competences concerning visualization, and PC image
processing as STROPHY GH34-PC pre-diagnostic application

Visualization system
Multi Video Designs develops any kind of video sequencer
: compatible screen
for CCIR or STANAG screen
|
|
 |
|
|
|
|
|
|
|
| |
|
|
|
VGA, SVGA image display system of TFT flat
screen
Among its own products, MVD proposes an interface board
for TFT screens : TFT Express board |
