Core Zenith Technologies
Building on nine decades of innovation leadership, today’s Zenith develops core technologies that enable content security, robust transmission and future broadcast standards.
Pro:Idiom® Digital Rights Management System
The Zenith-developed Pro:Idiom system is a robust, highly secure Digital Rights Management (DRM) system. It provides high-quality security to facilitate rapid, broad deployment of HDTV and other high value digital content to the hospitality and healthcare markets. Zenith, which is the creator and exclusive licensor of Pro:Idiom technology, has made licenses available to qualified companies around the world.
Unlike other DRM approaches, Pro:Idiom has been designed specifically for the hotel and healthcare industries, resulting in lower costs, and reduced maintenance. Its world-class encryption technology, large installed base of more than 3 million devices, integrated design and attractiveness to interactive system providers make Pro:Idiom the clear choice for delivering HDTV services to hotel guests and hospital patients with confidence.
Advanced Warning and Response Network
Zenith is one of the key players behind the Advanced Warning and Response Network (AWARN), a new broadcast system that will harness the power of next-generation terrestrial broadcasting to significantly enhance the nation’s emergency preparedness for the public and first responders. AWARN is designed to leverage next-gen TV broadcasting to deliver reliable, rich media alerts to mobile and fixed receivers anywhere, anytime.
AWARN builds on the Mobile Emergency Alert System (M-EAS), which was adopted as a broadcast standard by the Advanced Television Systems Committee in spring 2013. Proven M-EAS is evolving into AWARN following the successful conclusion of a nationwide field trial and development program spearheaded by Zenith, along with PBS, LG Electronics, Harris Broadcast (now GatesAir) and NAB Labs.
AWARN is ideal for next-generation alerting because it bypasses bandwidth bottlenecks that overload cellular-based systems and has the ability to reach millions of devices – and people – simultaneously. AWARN will transmit rich-media alert messages with video, photos, graphics, maps and evacuation routes, radar images, text and audio (including text-to-speech.) AWARN can also geographically target alerts to devices and citizens who need them.
ATSC Digital Television Broadcast Standards
ATSC 3.0: Co-developed by Zenith, the “FUTURECAST™ Universal Terrestrial Broadcasting System” is a leading contributor to the optimal “physical layer” solution at the heart of the next-generation ATSC 3.0 broadcast standard, which is being standardized by the Advanced Television Systems Committee. The FUTURECAST system is designed to provide the optimized combination of broadcasting capabilities for fixed, portable and mobile use. Flexible parameters allow broadcasters to mix diverse services – from fixed 4K Ultra HD reception to deep-indoor handheld reception to high-speed mobile reception – in a single RF channel with maximum efficiency. FUTURECAST was co-developed by Zenith, its parent company, LG Electronics, and GatesAir as the foundation of next-generation terrestrial broadcasting in the United States and around the world. Zenith engineers also are playing an active role in the Future of Broadcast Television (FoBTV) global standards initiative.
ATSC 2.0: Zenith technical experts, in conjunction with LG engineers are involved in the development of backwards-compatible enhancements to the ATSC A/53 DTV standard, collectively known as ATSC 2.0. Working closely with LG engineers, Zenith also is exploring how ATSC 2.0 enhancements such as targeted advertising and non-real-time transmissions can be incorporated into the emerging ATSC 3.0 standard, which is expected to provide a flexible, extensible new platform for content delivery to mobile and fixed received in the years ahead.
Mobile TV: As co-developer of the core technology behind the ATSC A/153 Mobile Digital Television Standard, Zenith helped pave the way for the robust transmission of digital television broadcast signals to mobile and handheld devices. Beginning in 2007, together with LG Electronics and Harris Broadcast (now GatesAir), Zenith engineers devised the MPH (Mobile-Pedestrian-Handheld) transmission system. This technology augmented the Zenith-developed, industry-standard VSB (Vestigial Side Band) digital TV transmission system. In 2009, following extensive industry-wide field tests and laboratory evaluations, the ATSC adopted the Zenith MPH technology as a core element of the A/153 Standard. As a passionate advocate for mobile TV, Zenith worked with broadcasters throughout North America to assist in their implementation of mobile TV service, which sets the stage for next-generation mobile TV as a centerpiece of ATSC 3.0.
Digital TV: As the inventor of the VSB (Vestigial Side Band) digital transmission technology at the heart of the ATSC A/53 Digital Television Standard, Zenith has proudly helped lead the nation’s transition to all-digital broadcasting. The Zenith technology was chosen by the Digital HDTV Grand Alliance as its transmission system, recommended in 1995 by the FCC Advisory Committee on Advanced Television Service, and adopted in 1996 by the Federal Communications Commission as the U.S. standard for digital TV broadcasting – enabling transmission of HDTV, multi-casting standard-definition television and data broadcasting. Zenith holds essential patents for the U.S. broadcast standard ATSC A/53 and licenses its intellectual property on a reasonable and non-discriminatory basis. In fall 2007, Zenith formed a licensing pool with several other companies to collectively license their patents essential to the ATSC standard. MPEG LA, LLC (www.mpegla.com) is the administrator of the pool and has the authority to grant a single license under the essential patents of all the pool members, including Zenith.
