Distribute two HD-SDI sources / channels of HD video up to 1080p resolution to an unlimited number of displays over almost any distance. The HDbridge 2920 converts your receiver's HD-SDI output into a RF signal that is sent to a HDTV display's QAM digital tuner over coax cable. That means that you can send your content to an unlimited number of displays over nearly any distance - and change sources on any display simply by changing the channel on the display - virtually eliminating the need for a traditional AV matrix switcher. This solution is ideal for anyone looking for an easy and affordable way to support a large number of displays such as a sports bar, house of worship, or digital signage. Multiple HDbridge units can be combined to create a headend that will support over 100 channels on your video network at each display. The HDbridge enables quick setup through the Maestro software to customize your sources and channels, as well as a front LCD panel to control and monitor the unit. This unit is designed especially for high channel density environments where rapid deployment, advanced management and compatibility are critical. Used in some of the most famous ballparks in the world, this is an ideal solution for environments where you have a large number of displays, such as stadiums, entertainment facilities, or broadcast environments. Cables not included.
