VGA2Ethernet

Frequently Asked Questions

Compact external network frame grabber for capturing DVI, HDMI, VGA + audio signals and using a network to transfer the data to the target computer. VGA2Ethernet supports resolutions of up to 1920Ă—1200 and can achieve capture rates of up to 60 frames per second.

1. Does VGA2Ethernet work with the Gigabit Ethernet interface only?

The VGA2Ethernet was designed for Gigabit Ethernet, meaning that a Gigabit Ethernet interface is required on the target computer for optimal performance. VGA2Ethernet will also work with older 100BASE-T Fast Ethernet  and 10BASE-T network interface cards, but with a reduction in its performance.

2. How can I verify whether my system has Gigabit Ethernet?

Nearly every recently made PC or MAC since 2007 comes with a Gigabit Ethernet Network Interface Card (NIC). You may find out your network interface card model by going to the System Settings/Device Manager of your operating system.

3. How many frames per second can VGA2Ethernet capture?

It depends on the resolution of your screen, amount of changes on the screen, the screen refresh rate, your operating system and the speed of the computer that is acquiring the images. Uncompressed frame transfer generally yields lower results than compressed frame transfer. Please consult the Specifications for appropriate capture rates.

4. Does VGA2Ethernet reduce the resolution of the images it captures in order to transfer it over Ethernet?

No. VGA2Ethernet captures and transfers every pixel of the original VGA frame in RGB format. VGA2Ethernet uses lossless compression to transfer the image over Ethernet. In this respect, VGA2Ethernet provides better quality than a VGA-to-video converter paired with a Composite or S-Video grabber.

5. Can VGA2Ethernet work on Windows NT, Windows 3.x/95/98/SE/ME?

No. Unfortunately, some of those systems have very poor support or no support at all for Gigabit Ethernet.

6. The video mode that I am using is not listed in the list of supported modes for VGA2Ethernet. Can VGA2Ethernet capture it?

Yes. You may add custom modes through the VGA2Ethernet software, available as a free download.

7. What Linux does VGA2Ethernet support?

We provide a library for modern linux systems (i386 and x86_64 platforms) that allows to receive and decode frames from VGA2Ethernet devices. If you are interested in development of applications running on the VGA2Ethernet itself, please consult VGA2LAN Development Kit product.

8. Can VGA2Ethernet save captured signals as a movie?

Yes, the VGA2Ethernet application has the ability to save captured signals as an AVI file. Refer to #12 for more info.

9. Which AVI codec works best with VGA2Ethernet?

The choice of codec and codec settings depend on the requirements for the quality of the AVI. You may need to try several codecs with different settings to see which codec best fits your task.

10. Images grabbed from some sources appear to be slightly shifted right or left. How this can be fixed?

VGA2Ethernet has an automatic algorithm that crops visible images from the VGA frame. The algorithm may make a mistake, however, and be off by a few pixels. Please refer to Configuring Image Adjustments in section 18 of the Frame Grabber User Guide.

11. Can I connect two or more VGA2Ethernet devices to one computer and capture signals simultaneously? What is the resulting rate of capture for each VGA2Ethernet?

Yes you can connect two or more VGA2Ethernet devices and capture multiple signals simultaneously. You will need to run the VGA2Ethernet application for each VGA2Ethernet device attached. You will, however, notice a difference in frame rate for each additional active VGA2Ethernet. The higher the performance of your computer, the better the possible frame rate. Please note that you must start the VGA2Ethernet application after connecting each VGA2Ethernet.

12. With what software can I interpret the digital signal coming out of the Ethernet port of the VGA2Ethernet device?

The VGA2Ethernet frame grabber works by emulating a high resolution video camera for Windows. VGA2Ethernet is a DirectShow compatible device, which means that virtually any video capture software designed for Windows is compatible with VGA2Ethernet. For example, VirtualDUB can be used to record .avi files, Microsoft Media Encoder to record .wmv files, and RealProducer to record .rm files. VGA2Ethernet also supports QuickTime in MAC OS X and Video4Linux in Linux operating systems.

13. Does the frame compression on VGA2Ethernet hamper the quality of the output?

No. VGA2Ethernet devices use a highly efficient and advanced compression algorithm that does not in any way reduce the image quality of the output. Through the use of this algorithm, high transfer rates can be achieved without any losses.

14. Is VGA2Ethernet software compatible with MAC OS?

Yes. VGA2Ethernet is fully compatible with Mac OS X 10.3.x and up. All VGA2USB LR/HR/PRO devices also support the QuickTime API.

15. Can the VGA2Ethernet be used through a switch? I want to maintain my LAN interface and/or connect another Ethernet devices to my computer, but it has only 1 Ethernet port.

Yes. The VGA2Ethernet can be used through an Ethernet switch. This allows you to connect to your LAN and VGA2Ethernet through a single Ethernet port. By using a switch, you can also extend the length of the Ethernet cable and allow for a larger distance between the VGA2Ethernet and the VGA source, and the target computer.
