The Display Express PC is a compact, 1RU rackmount computer with Display Express software pre-installed, operating via Windows 7 Pro.
At Contemporary Research, we look at RF systems through the lens of integration. For that reason, we created a facility-wide TV and media control system that operates over the same RF cable as the channels. In use for over 15 years, the system has proved to be extremely reliable and simplified site's transition from analog to digital channels.
The success of Display Express control rests in its simplicity. Start with a selection of in-house channels, add our DX software or a custom control processor, distribute control over RF, and then integrate controllers at each TV, monitor or projector.
See 4th image above for an easy to follow signal flow display. It is laid out as follows......
1) Channel Origination:
QMOD HD Modulator/IPTV Encoders process media from SDI, HDMI, Component and RGBHV sources in to HD in-house channels.
RF outputs from the modulators are combined and amplified for site distribution.
2) Display Express:
Operates from Windows Win 7/8 Pro, Windows Server
Available integrated in Display Express PC or software for site's PC
Serves display control Web pages to PCs, tablets and smartphones
Setup pages create a database of controllers, groups, channels, and users
Preset pages create a database of commands linked to TVs
Schedule pages launch Presets by date, time, and cycle
