Optical Video Coupler (OVC)

When the loss of even one pixel can be detrimental, maintaining the highest data quality is paramount. Enter the OVC, which maintains the highest resolution while using fewer resources than traditional solutions.

When audio, video and HMI inputs and outputs need to be transferred from an operator station to a desired end location potentially many miles away, the best solution is a video and operator machine interface (OMI) environment.

A traditional video and OMI environment needs video adapters, USB signal adapters, KVMs, video over Ethernet streamers, network switches, displays, keyboards, mice, servers, and unique Ethernet appliances.


Negative impacts of a traditional video and OMI environment include:

  • Increased space demands (when space is already limited)

  • Increased power demands

  • Increased cost for each device and adapter

  • Increased number of cables

  • Increased hardware requirements whenever more data channels are needed

The Problem

4K video/HMI over Ethernet application

  • Two modules: one encoder and one decoder

  • No compression, no video latency

  • USB 2.0 (keyboard, mouse, etc.)

  • 1” x 2” x 3”

  • 14 watts @ 12 VDC

  • Uses SFP+ site for network link

  • SFP+ can be populated for either copper- or fiber-based networks

Uses Ethernet (UDP) multi-cast protocol

  • Video distribution of any size (limited only by network switch capacity)

  • Direct connect also supported, eliminating need for network switch

Built-in expansion capacity

  • Compression when running on low bandwidth links

  • Forensically embedded content using water-marking

  • Encryption for secure/sensitive links


The OVC is currently deployed on U.S. Navy surface ships and submarines. It has potential applications in the following industries:

  • Television and other media formats

  • Home

  • Corporate

  • Government/law enforcement

PDA Engineering’s Optical Video Coupler (OVC) video and OMI distribution system not only meets the demands of encoding and decoding video, audio, and HMI inputs and outputs without sacrificing data quality, but also replaces much of the traditionally required hardware. By reducing the number of devices, the OVC reduces the negative impacts of the traditional environment, all while being much smaller, requiring much less power, and costing less.


This system also adds features that are not traditionally implemented in video and OMI environments, such as real-time watermarking for the detection of deep-fakes and other forms of misinformation/deception.


The OVC is also able to tag the security levels for the content, allowing other network appliances to filter the appropriate security level to the corresponding devices.
