ELGIN, IL, April 11, 2024 – Hitachi Kokusai Electric Comark LLC (hereinafter “COMARK”), a manufacturer and supplier of DTV transmitters, encoding systems, and associated field services for over 50 years, has selected DTV Innovations LLC (hereinafter “DTVI”) Medusa for their LEX-2000 Encoder ATSC 3.0 Upgrade Solution.

The encoder also supports PSIP ingest, EAS, and top-of-the-hour station ID. The LEX-2000 platform is an extremely versatile product which now has a simple upgrade path to support ATSC 3.0.

The consolidated solution includes HEVC-DASH encoding, ROUTE, and the Broadcast Gateway functions with a very simple user interface for system configuration. Additional video programs can also be licensed on an as-needed basis. The upgrade uses a single, space efficient 1RU commercial high-availability server incorporating hot swappable redundant power supplies that has a simple interface to existing LEX-2000 encoder platforms.

The DTVI Medusa, is a Complete Station Solution for ATSC 3.0 transmission comprising a transcoder/DASH packager, Service Announcement/Signaling Generator & Broadcast Gateway all within 1RU single server appliance.
