Atlanta DTH (ADTH) has announced a major update that will expand the functionality of its NEXTGEN TV receiver by enabling gateway capabilities allowing viewers to stream NEXTGEN TV protected programming across multiple connected devices in the home.

The new capability will be delivered in time for the holiday season as a software update to existing ADTH receivers, extending support to Android and FireOS client applications. These are the first in a planned series of supported platforms which will be followed by Roku and others.

Working in collaboration with the ATSC Security Authority (A3SA), ADTH has integrated secure gateway implementations for NEXTGEN TV, advancing the capabilities of ADTH receivers and reflecting continued progress toward a fully interoperable consumer-ready gateway ecosystem.

In addition to the software update, new ADTH Gateway devices incorporating these capabilities from launch are planned for release in 2026, expanding consumer choice for accessing free high-quality over-the-air television on a variety of screens.

“We are proud to partner with A3SA in bringing the benefits of NEXTGEN TV to more viewers,” comments Ivy Shou, President of Atlanta DTH. “This update makes it easier than ever for consumers to watch live local broadcast content securely and seamlessly on the devices they use every day.”

As part of this rollout, the ADTH TV App which is currently available for use with the company’s USB dongle will also be updated to support these new features.

The ATSC 3.0 broadcast standard offers content protection features not available with the original (ATSC 1.0) broadcast television transmission standard. The ATSC 3.0 standard ensures that all broadcaster signaling sent to the viewer’s receiver is ‘signed’ (i.e., certified as authentic). This ‘signature’ uses advanced cryptographic technology and is a secure way for the broadcaster to identify and certify the service and attendant signaling tables to be true and authentic.

If the broadcaster chooses to include an attendant application (such as a station-based or network-based app), it can include in the transmission an additional digital signature to provide to the viewer’s receiver evidence that the application is indeed authentic and has not been hacked. This feature is especially important to consumers who choose to register their personal details with a related application.
