International. A new television transmission system, with technologies that improve broadcasting performance and flexibility, has been proposed to the Advanced Television Systems Committee (ATSC) as the "physical layer" for the emerging ATSC 3.0 standard.
The Universal Terrestrial Broadcasting System (UTB), known as Futurecast, was proposed by LG Electronics and Harris Broadcast and developed as the foundation for state-of-the-art terrestrial broadcasting in the United States and around the world. Some of its highlights are:
- It is designed to increase data throughput to 30% and to improve multipath performance (compared to the current DTV standard) for fixed and portable TV reception.
- For mobile TV reception, Futurecast UTB includes power-saving features for consumer receivers and enhanced indoor TV signal penetration, thanks to flexible encoding options.
- Advanced modes also offer very high data rates or very robust transmission capabilities.
Skott Ahn, President and Chief Technology Officer of LG Electronics Inc., speaking on behalf of the co-creators of the Futurecast Terrestrial Universal Broadcasting System, said that "future television broadcasting standards will need to break new ground in many areas, starting from a transmission system that is powerful, spectrum efficient, robust, flexible and extensible. That's what our joint proposal for the system is all about."
The technical proposal for the ATSC, recorded in 250 pages, is also compatible with single frequency networks and / or multiple transmitters, and its flexible use of a single RF transmission ensures optimal quality of service. The new extensible system is designed to support the evolution of future broadcasting systems even beyond ATSC 3.0.
