Tutorials. How to Stream DVI, HDMI or VGA over the Network
This tutorial explains how to send VGA, DVI or HDMI video over an Ethernet/IP network. For capturing, streaming and broadcasting VGA, DVI, or HDMI video data you can use one of Epiphan's broadcaster - streaming products. Epiphan's integrated capture, encoding and streaming hardware features an Ethernet/IP output to stream and broadcast video from HDMI, DVI or VGA over an Ethernet/IP network. The video stream is accessed and viewed by web browsers, media players, content distribution networks and set top boxes.
Sample Application - Streaming DVI Video source using VGADVI Broadcaster
In this example we will broadcast a video stream captured from a DVI video source such as a computer display, camera or microscope. You will need the following equipment:
- DVI video source,
- VGADVI Broadcaster,
- DVI-to-DVI cable,
- Ethernet cable,
- A computer with a web browser or media player to view the stream
- A working Ethernet/IP network path between the capture site and the viewing site
Anyone can access this video stream no matter wherever he/she is located using the URL for the video stream broadcast information obtained from the administrator as described below.
Step 1: Required connections
Step 2: How to find the URL for the DVI, HDMI or VGA Video STREAM
If you do not already know the URL for the stream being broadcast, Epiphan provides a network discovery software application or an iOS app to find the URL for VGA, DVI or HDMI streams available on the network. To use these applications it is necessary to install the application on a PC or iOS (iPhone, iPad ) device on the same sub-network where the broadcast device is capturing the source.
Step 3: Viewing the URL Stream broadcast

Step 4: Streaming VGA, or HDMI sources
In order to stream VGA, or HDMI video sources, you follow the same instructions above, however with different video connector cables or adapters.
More advanced users may also enhance this solution by:
- Adding a second SD video source for picture in picture streaming
- using VGADVI Broadcaster Pro, or VGA Grid ( More Info )
- Adding multiple HD, SD and audio sources
- Stream natively and directly to iOS without CDN
- Create and stream mulitple views of VGA, DVI, HDMI and camera sources
- Create different streams with higher and lower bit rates or other CODEC settings
- Transmitting streams using multicast technology,
- Publishing the VGA, DVI or HDMI stream to a content distribution network. This adds scalability, deals with firewall issues, and provides broader device and stream type support
- Streaming over WiFi with multi cast, or other LAN/WAN architectures
Please consult the product documentation or other case studies on this website for these more advanced applications.
Lossless Video Capture Frame Grabber over Ethernet/IP
For lossless capture of images over Ethernet is best done using a VGA2Ethernet frame grabber directly connected to a Capture Computer’s Ethernet port, or to a router on the same subnet as a Capture Computer. This solution will have the highest image quality, but will consume the most bandwidth and have a lower frame rate than with Epiphan’s integrated capture, encoder, recording and streaming hardware.
