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.
