Worship Centers have taking the lead in innovating new uses for video and signage within their facility. And not just mega-churches – as the cost of HD technology has dropped significantly, everyone can take advantage of new solutions in audio, video and HD media creation and distribution.
HD-SDI Video Distribution
The most popular application in worship centers is distributing HD-SDI over RF as an HDTV channel, using the QMOD-SDI HD-SDI Modulator. Distributing HD-SDI over distances is problematic and often requires re-clocking gear – not to mention that TVs will need SDI to HDMI interfaces. Using RF, you can distribute many channels at the same time over long distances, and TVs already have HD tuners to view the channel. Some sites will run other sources such as DirecTV or DVD through their SDI switcher during the week to provide content to rooms during the week.
HDTV Digital Signage
Another popular option is to convert PC signage to an HDTV channel using the
QMOD-HDSC Scaler Modulator. Unlike HD-SDI, PC video outputs don’t exactly provide a precise resolution or refresh rate (PC “720p” can use up to 755 lines!). The internal HD scaler in the modulators conforms VGA to broadcast standards, and can shrink and position the video to compensate for overscanning on the TVs. Some site use “official” signage technology, others use Final Cut Pro or other apps for stunning motion signage.
Once you have a lot of TVs in the system, controlling power and channels can be difficult. Sites with many displays use our Display Express system to manage the TVs through the same RF pipeline as their in-house channels. Simple fill-in-the-blank forms make it easy to define the initial system and adapt to changes in the future, no additional programming is required. You can even create Web-accessible control panels and send IP commands to non-RF devices such as video projectors. There’s only a few components used in the system:
- Software. Use our Display Express software, or AMX, Crestron or other systems.
- Control Channel. A box in the RF head end receives the IP or RS-232 commands from the software, and sends them as a small data channel over the RF system. It fits in the gap between channels 4 and 5, so it won’t affect existing channels.
- TV Controllers. Each TV is controlled by a small IR or RS-232 module that recieves the control channel and manages the TV.
