Frame Grabber Specification Comparison Table Updated
July 3, 2009 by Victor
One of the most visited pages on our site is our massive and extremely informative feature comparison table for the world’s best VGA and DVI frame grabbers. Since it was created, some manufacturers have changed the specifications for their devices, while Epiphan Systems introduced the VGA2Ethernet frame grabber, which is now part of the table.
The first thing that you may notice is that the VGA2Ethernet has much higher specifications than any other frame grabber on the market. This is due to the fact that the VGA2Ethernet is a much more sophisticated device and, as such, is not really comparable to the other grabbers.
Why is the VGA2Ethernet different?
You can think of the VGA2Ethernet as a separate small computer equipped with a frame grabber. As such, it is able to function remotely. In other words, the VGA2Ethernet does not have to have close proximity to the target computer, as is the case with PCI or USB based frame grabbers. As shown below, the only requirement for the VGA2Ethernet is that it be on the same network as the target computer, and within proximity of the source that it is capturing the VGA signal from.
The fact that the VGA2Ethernet can be separated from the target computer distance-wise is not the only thing that makes this device different from others, however. By using the Gigabit Ethernet bus to transfer the images and a PowerPC processor paired with an advanced FPGA, the VGA2Ethernet is able to digitize images at resolutions up to 2048 x 2048 and, depending on the change in content from frame to frame, transfer them at up to 120 frames per second, making the VGA2Ethernet significantly faster than other any frame grabber available on the market.
