Broadcast a VGA Signal over Wi-Fi With Ease

A while back, we had an article that featured a device made by IOGear that broadcasts a video signal over Wi-Fi to a VGA output. Now, Epiphan Systems has released a device, the VGA2WiFi, that does almost the exact opposite.

Imagine you are giving a presentation or a lecture and you would like to give your audience real-time instant access to what is being displayed on the conference screen. Normally, you’d have to either prepare slides ahead of time and hand them out ahead of the presentation or make them available later. This might be alright if you are using PowerPoint only, but imagine that you are demonstrating the image from a VGA device that is not a computer, such as an embedded machine, electronic microscope, or medical device.

The VGA2WiFi solves this problem by taking any VGA signal, converting it into a digital image, and broadcasting it over 802.11g Wi-Fi for your audience to view. As long as your viewers have access to any 802.11b/g-enabled device with a web browser, such as a smartphone, PDA, or notebook computer, they are able to view the presentation on their screens as it happens. No additional software needs to be installed.

What’s more, the VGA2WiFi works with signals of up to 1600 x 1200 and broadcasts a true lossless image, meaning that 100% of the source image quality is retained, which is important for environments where a high level of precision is required.

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.
