Connect the transmitter to a VGA connected video source, and connect multiple receivers to multiple monitors to get synchronized Audio and Video content displayed.

• Powerful video distribution system that handles up to 32 wireless displays or more than 1,000 wired displays
• Uses standard Ethernet cabling and hardware for compatibility with existing network infrastructures
• Unique multicast digital technology eliminates signal degradation over long distances

The Multicast Video Distribution System (MVDS) from Silex allows High Definition (HD) video and stereo audio to be distributed and synchronized across wired or wireless networks. Designed for OEMs and System Integrators, MVDS provides a highly flexible way to handle digital signage applications in almost any kind of environment.

MVDS uses digital multicast technology with a highly efficient real-time compression algorithm, allowing unparalleled high quality video and audio signals to be simultaneously transmitted to up to one thousand digital signs.  The major advantage of this technology is the flexibility to connect digital signs using industry standard Ethernet cabling and hardware, or via 802.11a wireless networking.

Because MVDS is Ethernet-based, users can take advantage of their existing network infrastructure* and inexpensive off-the-shelf networking hardware.  As a result, digital signs can be quickly and easily installed throughout a building or campus environment without the need to buy expensive analog splitters and repeaters. Ethernet technology also enables superior distance capabilities, and unlike traditional VGA to Cat 5 analog video transmitters, the picture quality does not degrade over long distances.

The new MVDS Real-Time Content Selection capability allows a user to select video/audio content from multiple sources without the need for external switching hardware .   This allows, for example, a program to be interrupted with a public service announcement.  The switching process is instantaneous, and can be user-initiated or timer-based.

The MVDS wireless capabilities allow users to easily install digital signs in locations where running cables is difficult or where the digital signs must be moved around.  This makes it ideal for handling mobile or temporary displays, and for connecting digital signs in old buildings or across public thoroughfares.For maximum OEM configuration flexibility, the MVDS transmitters and receivers are available in either compact standalone metal enclosures or as board level products.

Applications

MVDS can be used in virtually any digital signage application, including airport arrival/departure displays, trade shows, retail advertising, public announcements, entertainment, classroom instruction, courtrooms, and much more.  Its wireless capabilities allow it to address many additional applications such as mobile classrooms, emergency information displays, and kiosks.

*Because MVDS generates a large volume of multicast traffic, it should be on its own isolated network segment. 

Features and Benefits
