In broadcasting field, the company has been selected as gap filter developmental company in satellite DMB project proceeded in SK in 2003. Thus, the company develops, supplies, installs, and operates signal processor of gap filter until today. In addition, instrument to test gap filter using GATT(Gap Filler Analyzer and Terminal Tester) is being supplied to SKT as well.
In ground-wave broadcasting filed, Exciter for ATSC and ACU is developed with self-owned technology and supplied to local broadcasting stations including KBS.
Exciter for ATSC is a core instrument of relay tool for ground-wave broadcasting. It replicates broadcasting signals received, determines error-free signals, and transmits the re-modulated signals. Exciter is possible to transmit high-quality signals with low cost, as it possesses DPD(Digital Pre-distortion) for compensating linear distortion by HPA and nonlinear distortion by channel filter. ACU for ground-wave broadcasting is located on ground-wave relay stations and functions as controller of instruments (Exciter, HPA, Power etc.) consisting relaying instruments. Also, the company developed outdoor exciter and ACU for the first time in Korea. Instruments make it possible to cover areas that broadcasting does not reach by enabling the easy installment of relay instrument in those areas.
