Unlike many other large venues, churches typically don’t have the budget, staff or infrastructure to handle the constant technological upgrades that most commercial venues their size would. As a result those of us in the church world have to find a way to stretch every penny we spend and every piece of technology we buy. For example, when you upgrade to that new HD-SDI video switcher, it may really improve the video quality in your auditorium, but might cause you problems throughout the rest of your building. At this point you can put SDI all through your building and update your TV’s or you can use your existing TV’s (as long as they have a tuner) that you probably have and cross- or down-convert your signal for RF distribution. If you do the math the RF distribution is going to be cheaper, especially if you already have TV’s and more importantly signal path that you can use.

Contemporary Research makes a solution for this scenario, the QMOD-SDI 1.5 HD-SDI Modulator. This product has the potential to help you stretch your current investments when making capital upgrades, by allowing your HD-SDI signal to be easily distributed on an RF network. The modulator creates a high-definition 720p/ 1080i MPEG-2 stream for broadcasting over RF. It delivers a fully agile QAM 64/256 digital cable channel 2-135, and streams IPTV from the GigE Ethernet port giving you a couple of different options for delivery.

With a variety of connectors on the QMOD modulator, it accepts a variety of signals and formats including standard SDI, 3G SDI, and 60/30 Hz feeds from prosumer SDI sources on the SDI input. It also has one component input for 1080i, 720p, 480p, 480i video, one composite video input along with stereo, optical and coax audio inputs. The product will be available later this fall, so I didn’t get to test this, but I assume this means that even if you are currently running an SD signal chain you should still be able to get signal distributed through this modulator. That way if you aren’t to the point of having an HD-SDI or 3G-SDI production switcher you can distribute your current content with your current signal format, without fear of having to redo that work in a few years when you have made upgrades. No one appreciates future-proofing as much as church techies, and this solution definitely has the opportunity to be a good long term investment. It also has the option to upgrade later to full scaling and dual-channel operation, which is accomplished via upgrade key codes, insuring that this investment can meet your needs now and further down the road. Contemporary Research says the second channel offers HD Component allowing a church to add a cable feed or digital signage for a nominal investment. Next page
