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…

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…

Doug’s Q-Tips – How Does MPEG Encoding Work?

We refer to our QMOD solutions as HD Modulators – IPTV Encoders. That covers a lot of ground and requires a bit of explaining. A QMOD is an Encoder, as it accepts a video source and encodes it into an MPEG-2 stream. From there, it can package the stream to be carried over RF coax by an HD RF channel, a process called modulation. In addition, it can package the same…
