Comark Announces Cost Effective LEX-2000 ATSC 3.0 Upgrade Solution

COMARK has announced the release of the LEX-2000 ATSC 3.0 Upgrade Solution. The LEX encoder has been available for many years and is currently used by broadcasters for LPTV and disaster recovery market segments.

The LEX‐2000 is a powerful yet low-cost ATSC 1.0 encoder / multiplexer, that can be configured with all the necessary functions to get a DTV station on-the-air with up to 8 video programs. It uses a compact 2RU dedicated hardware platform and includes many built-in source connections to support HD-SDI, SD-SDI, NTSC Analog, as well as an ASI input for MPEG2 transport streams. 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 LEX 3.0 Upgrade pairs the LEX-2000 with the DTV Innovations Medusa product for a simple and cost-effective upgrade path to NextGen TV. 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 Upgrade also accommodates ESG, AEA/AEI, and NRT ROUTE data encapsulation for ATSC 3.0 “Datacasting” of related and unrelated IP Data for broadcast. The solution provides an ATSC 3.0 A/324 compliant STLTP output that integrates seamlessly with the EXACT-V2 ATSC 3.0 compliant DTV exciter that is used throughout the company’s DTV transmitter product line.
