A first in the market of high resolution video capture hardware, Epiphan Systems has announced a new open source frame grabber – Epiphan Lecture Recorder.

According to the product page, shipping of the Lecture Recorder will start sometime in November. Epiphan Lecture Recorder, or ELR in short, has some promising features that, at the price tag of $2000, are unbeatable by similar offerings.

ELR’s Unique Features

Even though this product seems to be aimed at the educational market, Epiphan Lecture Recorder has some unique features that make it a perfect frame grabber for pretty much any application. Firstly, ELR supports not only DVI and VGA capture, but also has on-board inputs for composite video and stereo audio.

Furthermore, Epiphan Lecture recorder has a very generous 32GB of buffer memory, which is expandable via portable flash sticks, network drives, or external hard disks.

Finally, ELR features 5 USB ports for external devices and peripherals, meaning that you can create software that will allow you to connect external control devices such as IR remotes, CD/DVD writers, wireless modules, an so on.

Open Source

As mentioned earlier, Epiphan Lecture Recorder will be an open source device. What this means for developers is that it is possible to access all features of the frame grabber. And, because the ELR is more of an embedded computer or internet appliance, many interesting applications can be written for it. For example, the ELR, as it has an Ethernet network interface, can function as its own server, as pictured below.

In a Nutshell

The Epiphan Lecture Recorder is more of a computer with on-board frame grabber and video and audio capture cards than it is an actual frame grabber. While this might not be the ideal device for the general public, the ELR could be used as a platform for a wide variety of applications.

A Simple Solution for Control Room Monitoring

December 16, 2008 by Victor · Leave a Comment 

Imagine that you have multiple monitors that need to be either constantly monitored or remotely accessed. Normally, this would be impossible to do using conventional equipment. You would either have to individually access each monitor or use complicated analog video monitoring equipment. Now, with the release of Epiphan Systems’ VGA Grid, monitoring up to 256 VGA outputs (or monitors) is simple.

In order to use the VGA Grid system, one VGA Grid device (about the size of paperback novel) must be connected to the output of each VGA signal. The VGA Grid must also be able to access the Internet or LAN through its built-in Gigabit Ethernet interface. Once these two conditions are met, you are able to remotely log into a web-based control panel which displays the output of each of your VGA signals on one screen. Of course, you are able to zoom in on each VGA signal individually and archive the output for later viewing.

Since the VGA Grid is a frame grabber-based device, it is able to monitor VGA signals with resolutions of up to 1600 x 1200 and relay the images from them in 100% lossless quality, which is important in mission-critical control room applications.

If control room monitoring or combining many VGA streams into one signal is essential to your organization, then the VGA Grid is a product that you should seriously consider. Not only is it compatible with any existing Ethernet-based LAN infrastructure, it is the ultimate solution for the combination of multiple high-resolution video signals onto a single screen.

Easily Duplicate a VGA Signal to Anywhere in the World

Gone are the days of WebEx and high-priced license-based collaboration solutions. Epiphan Systems has introduced a simple yet powerful VGA-based conferencing product for online collaboration and monitor synchronization.

The VGA Bridge, promises to “bridge” the distance gap between two monitors or projectors, whether they be in the rooms next to each-other or accross the world.

It works by digitizing the analog VGA signal into a compressed digital format that is suitable for web broadcast and then sending it to the receiving VGA Bridge for uncomression and reproduction. While this is not a new concept in the world of web-enabled streaming content, the fact that the VGA Bridge can handle resolutions up to 1600 x 1200 in 100% lossless quality is a first. Of course, you would need a fast and stable Internet or Gigabit LAN connection in order to achieve transfer rates of up to 60 frames per second, but that is to be expected from such as high-end and specialized product.

If web-based collaboration, telemedicine, or remote monitor synchronization are critical to your application, we suggest that you seriously consider the VGA Bridge from Epiphan Systems.

New, Revolutionary VGA Frame Grabber Released

December 8, 2008 by Victor · Leave a Comment 

With current high end PCI-based and USB-based VGA frame grabbers pushing maximum capture rates of 60 frames per second, a VGA frame grabber that could capture at twice that rate seemed like a far-fetched idea… until today.

Already up for sale on this page, the VGA2Ethernet frame grabber claims to operate at a maximum resolution of 1600 x 1200, at which it can capture at a maximum rate of 66fps. However, that number is 120fps for lower resolutions.

Typical of any frame grabber made by Epiphan Systems, the VGA2Ethernet is external, portable, and has the same recording, archiving, and broadcasting functions of its smaller siblings. You may find a detailed review of these functions in our Epiphan VGA2USB LR Review.

Unlike any other VGA or DVI frame grabbers, the VGA2Ethernet, as the name suggests, plugs into the Ethernet port of the target computer. While GigE and other machine vision frame grabbers have been using the Ethernet protocol for some while, emplying Ethernet in a VGA frame grabber is a first for the industry. VGA2Ethernet uses the Gigabit Ethernet protocol, which is what allows it to achieve such high transfer rates when compared to traditional USB or PCI frame grabbers.

Besides the capture rate advantage, using the Ethernet protocol also allows you to extend the distance between the actual frame grabber and the target computer, as long as both the grabber and the target computer are on the same LAN. A diagram is shown below (taken from

Stay tuned for more news and reviews as more information is released by Epiphan Systems about the VGA2Ethernet.
