Hitachi Kokusai Electric Comark Releases EXACT-V2 IP Optimized DTV Exciter

SOUTHWICK, MA, April 12, 2017 ― Hitachi Kokusai Electric Comark LLC (hereinafter “COMARK”), a manufacturer and supplier of DTV transmitters, encoding systems, and associated field services for over 45 years, has announced the release of the EXACT-V2 “IP Optimized” next generation DTV exciters supporting ATSC 1.0 and ATSC 3.0. The new platform will be on display at the company’s booth (C4309) in conjunction with an end-to-end ATSC 3.0 demonstration.

The EXACT-V2 DTV exciter is the next generation platform used throughout the company’s DTV transmitter product line. EXACT-V2 delivers an ATSC compliant, on-channel RF output and performs RF precorrection of both linear and non-linear distortion with the company’s industry leading Digital Adaptive Precorrection (DAP) technology. DAP automatically corrects both the linear and non‐linear system distortions inherent to all DTV systems. The use of DAP provides the lowest cost of operation with very high system efficiency and RF SNR performance.

EXACT-V2 is an “IP Optimized” platform that features seven Gigabit Ethernet ports. The exciter is compatible with the STL interface (A/324) plus it offers (optional) built-in ALP encapsulation. It features “DualCast” technology, which is easily upgraded from ATSC 1.0 to 3.0 protecting investment today for use tomorrow.

EXACT-V2 includes a simple local control and monitoring using a front panel backlit LCD display. The exciter can also be remotely controlled via user friendly and intuitive built‐in web GUI. Finally an optional SNMP client is available for operators that want to incorporate a third party NMS.
