In the coming battle between ATSC 3.0 and 5G for eyeballs, will only one technology win? Can they be complementary?

ATSC 3.0 proponents continue to remind the industry of coming new capabilities, opportunities and advantages. Yet, the consumer electronics industry remains quiet on implementing such features in new consumer televisions and related products. This article reviews the options and benefits 3.0 offers.

From the FCC perspective, ATSC3.0 is only a polite suggestion; adoption is totally voluntary by broadcasters. There is no FCC mandate to transmit 3.0 and the government certainly is not going to again hand out a billion dollars’ worth of free 3.0 TV tuners. And, ATSC 3.0 is not backwards compatible to 1.0, Broadcasters are mandated to maintain a free channel AND support 1.0. This is a pull versus push technology transition. Then there is the likely competitor, 5G.

Learn more about this important transition in the article, “Is ATSC3.0 the TV of Tomorrow?”

What’s the difference between mic and line level audio? If you think this basic question is overly simple, you might be surprised to learn that many people working in pro audio today don’t know the difference.

Of the four main types of audio signals, microphone level is the weakest and requires a pre-amplifier to bring it up to line level. Microphone level is usually specified between -60 and -40 dBu. (dBu and dBV are decibel measurements relative to voltage.) A line-level signal is about one volt, or about 1,000 times stronger than a mic-level signal. And, there are several standard line levels.

But, which level should you use as standard? Read the article, “The Difference Between Line and Mic-Level Audio,” to refresh your memory on audio levels and ensure your facility provides the highest-quality audio possible.
