In August, the two companies submitted a proposal for the physical layer of what’s being called ATSC 3.0, but declined to comment on what that proposal entailed. The companies said today that its standard, dubbed “Futurecast Universal Terrestrial Broadcasting System,” was developed as a next-generation system not just for the U.S., but for around the world.
LG developed the current ATSC broadcast standard used in North America today.
Notably, LG and Harris’ proposed solution doesn’t mention taking core technologies from DVB, the European standard, which has been included in several of the 10 proposals submitted to ATSC.
According to the companies, Futurecast is expected to increase data throughput by 30 percent, while maintaining reception coverage and improving multipath performance for fixed and portable TV reception — one of the primary goals of ATSC 3.0, as laid out in the call for proposals. A 30 percent increase in throughput would mean each channel could operate with about 25 Mb/s of spectrum.
When it comes to mobile TV reception, Futurecast includes energy-saving features for consumer receivers and enhanced indoor TV signal penetration, using flexible coding choices, according to the companies.
Included advanced modes will help deliver high data rates, or robust transmission capabilities, for things like 4K broadcasts, according to the companies.
The proposed system also aims to provide state-of-the-art error correction coding and signal constellations over OFDM modulation.
“Future television broadcast standards will require blazing new trails in many areas, starting with a transmission system that’s powerful, spectrum efficient, robust, flexible and extensible,” Skott Ahn, president and CTO of LG Electronics, said in a statement.
Futurecast aims to be as open as possible, in order to support future broadcast systems beyond ATSC 3.0, according to a release.
ATSC 3.0 is expected to move to a candidate standard in the next two years, with a final standard expected to come in 2016, says Mark Richer, president of the ATSC. This month, companies and individuals who submitted a proposal for ATSC 3.0 plan to meet and give a tutorial on their respective standard to the ATSC.
