Applications

Its key application is in-house broadcasting (MATV) for content owners to cost-effectively distribute within multi-storied buildings or high-density areas. The HD Encodulator is perfect for commercial, residential, government and academic applications. Further, the industries such as healthcare, leisure & hospitality, and religious/spiritual can greatly benefit.
Receiving video and audio signals from a STB (CPE), digital camera/camcorder, VCR/DVD, the HD Encodulator encodes then modulates for output to UHF/VHF channels. Additionally, this product is used in retransmitting satellite and CCTV signals through a coaxial cable.
