Are You Ready for 4K and ATSC 3.0?

If you’re not, don’t sweat it. 4K isn’t ready for 4K, and ATSC 3.0 isn’t either. Spoiler Alert: 4K TV RF/IP rests on a number of emerging technologies, so this blog is a longer than normal. Your Eyes Aren’t 4K The problem is, your eyes can’t discern 4K from normal viewing distances. You’d have to be less than 10’ from your 75” 4K TV to begin to see…

QMOD-QIP Encoders now accept 1080psf24 video

Just when you think you know a thing or two about video formats, you find there’s always one more thing you didn’t know about. 1080psf24 stands for Progressive Segmented Frames.

Working with Latency in Digital RF Applications

Latency is the delay between the video source and the time it takes to appear on the TV or screen. For live presentations from an on-site video switcher, the delay is usually due to scaling and rescaling the video, as well as processing delays in switching and effects. This can typically range from nearly instant to a few seconds. In digital RF and IPTV, an HD program…

Daisy-Chain RS-232? Control 232-ATSC series tuners with IP switch

For years, integrators have controlled up to 9 232-ATSC series tuners from one RS-232 using a “daisy-chain” RS-232 cable.  It’s an effective solution, but the cable can be complex to wire – and if one tuner must be removed, the chain is broken. However, the previous 232-ATSC+1 and current 232-ATSC 4 tuners also support IP control. Now that AMX, Crestron and others…

The importance of scaling in a “not exactly perfect” video world

In a perfect video world, scaling is not required. For example, broadcast-quality video has exactly the right resolution, correct number of lines, and a refresh rate of precisely 59.94 or 29.97 Hz. Everything in the video chain conforms to broadcast standards, so system integration and video processing works seamlessly by design. However, in the AV Integration world,…

Doug’s Q-Tips – Viewing QMOD/QIP Web Pages from the USB port

When you don’t have an Ethernet connection – which is often the case in a new installation – you can view the QMOD Web pages through the front USB port.  The IP address of the USB port on the QMOD is 192.168.227.227. You will need to assign a special address to connect with the QMOD internal network: Connect a USB cable from the QMOD to your Windows PC.  The unit…
