Broadcasters and the payoffs of IP TV
While the current MPEG transport stream has worked well, it’s time for a change that will let over-the-air TV broadcasting break free from its own self-imposed silo and transition into something “that could be thought of as an extension of the internet,” according to Triveni Digital’s Rich Chernock. He details the ways such a change could benefit both broadcasters and viewers.

The MPEG transport stream has served the broadcast television industry well for about two decades, providing the container format for transmission of video, audio and other data that makes DTV possible.
But all good things must come to an end, and it appears MPEG TS’s days in broadcasting are numbered.
“To be honest, there is nothing wrong with transport stream. It worked beautifully,” says Rich Chernock, chief science officer of Triveni Digital and chair of the Advanced Television Systems Committee technical group with overall responsibility for ATSC 3.0. “I think it was a brilliant design.”
However, the next-generation TV standard nearing completion by the ATSC and under consideration at the FCC ditches MPEG TS in favor of IP transport.
But why? Why replace a well-proven technology that delivers TV today to millions of over-the-air viewers with IP transport, and in the process ask viewers to make changes to their receivers and require broadcasters to make millions of dollars in new capital expenditures?
In other words, what’s the payoff for viewers and broadcasters alike?
Carriers yielding to petition to unlock FM radios on many smartphones

Many smartphones on the market today ship with FM radios included as part of the hardware. The only thing preventing you from tuning into your favorite rock station or local golden oldies is that this FM functionality is shipped turned off. However, a Canada-originating campaign to end the tyranny of radio-less phones has been gaining quite a bit of traction, and carriers are actually starting to bend. In the US, at least. Canadian carriers are still reluctant to put in the request to manufacturers to turn the FM feature on.
Why wouldn’t carriers want you to have a radio on your phone? The answer is actually pretty straightforward: most carriers would prefer that you get your music by powering through your data plan into extra charges or let you feel the pressure to upgrade to a larger, more expensive plan. The “Free Radio on my Phone” petition thinks this is more than a little shady. “They make a lot more money off of streaming radio or other sources through the data transfer,” says Barry Rooke, the campaign organizer.
