1. What is the difference between DVI Broadcaster DL and VGA Broadcaster?

DVI Broadcaster DL is able to acquire a dual-link DVI signal (up to 2048x2048), while devices in the VGA Broadcaster line of products can capture single-link DVI and VGA signals at resolutions up to 1920x1200.

2. What Ethernet interface is required for DVI Broadcaster DL to work?

DVI Broadcaster DL performs on-board compression such that a 100 Mbps network connection should provide enough capacity for effective transmission of video content.

3. How many frames per second can DVI Broadcaster DL transfer?

DVI Broadcaster DL transfers up to 30 frames per second at any given resolution up to 1920 x 1080, 15 frames per second at 2048x2048 resolution, and 10 frames per second at 2650x1600 resolution. Capture rate diminishes when the an audio signal is paired or when there are more than 1 unicast clients.

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

No. DVI Broadcaster DL captures and transfers all data in original resolution.

5. Can DVI Broadcaster DL function over a Local Area Network (LAN) or does it need a constant connection to the Internet?

DVI Broadcaster DL can act as its own web server, meaning that it has the ability to function in LAN environments which are not connected to the Internet. In this case, only viewers that are part of the LAN are able to view the broadcast.

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

DVI Broadcaster DL supports all resolutions up to 2048x2048. Please contact us if you have questions about a specific application.

7. How can I configure the DVI Broadcaster DL?

Although the DVI Broadcaster DL is a simple "plug-and-play" device, configuration can be performed through an intuitive web interface.

8. What compression does DVI Broadcaster DL use to transfer data over Ethernet?

DVI Broadcaster DL uses ASF (MPEG4), H.264 or MJPEG video stream to transfer data to the audience of the DVI Broadcaster DL-powered broadcast. These streams may be viewed by video applications such as VLC, Windows Media Player, through the Flash Player in most browsers and others.

9. What CDNs does DVI Broadcaster DL Support?

DVI Broadcaster DL supports the RTSP transfer protocol for CDNs (Content Distribution Networks). Thus Broadcaster  is compatible with virtually any content RTSP-supporting distribution network, such as Streamzilla.

10. What are the considerations for multiple participants, unicast/multicast modes?

When deploying your webcasting/broadcasting solution there are trade-offs on bandwidth, performance, privacy and quality of the video/audio presentation. You need to carefully plan and consider these trade-offs based on the capabilities of your networks. Within the LAN : Multicast provides for unlimited participants, but multicast is easier to manage than on public network. For multiple participants over the WAN, unicast is more secure and reliable.

11. What if I want to broadcast to more participants?

Using a content delivery network (CDN) or a separate distribution server is recommended if simultaneously streaming to multiple participants.

12. What if I want to broadcast multiple video sources?

VGA Grid supports streaming of multiple input sources.
