CATV Modulators

CATV Modulators are professional solutions designed to convert HDMI, HD-SDI, or IP sources into RF channels that can be easily distributed over existing coaxial cable infrastructure. By transforming digital signals into CATV-compatible RF outputs, these devices allow content providers, broadcasters, and enterprises to create their own channel lineups with high-definition video and crystal-clear audio.

Thor Broadcast offers a wide range of CATV modulators, each designed for different applications – from HDMI distribution in hotels and schools, to HD-SDI broadcast in live events, to IPTV integration for large-scale networks.

HDMI RF Modulators
HDMI RF Modulators convert any HDMI source – such as media players, Blu-ray, or satellite receivers – into custom RF CATV channels. These modulators support international standards like DVB-C QAM, ATSC, DVB-T, and ISDB-T, making them versatile and cost-effective for hospitality – education – and enterprise video systems.

HD-SDI Converters
HD-SDI Converters are designed for professional broadcasting environments. They encode and modulate SDI signals (SD – HD – up to 3G-SDI) into MPEG-2 or MPEG-4 RF channels, ensuring low latency and broadcast-quality clarity. Ideal for stadiums – theaters – houses of worship – and live productions.

IP to CATV Edge Modulators
IP to CATV Edge Modulators transform IP transport streams (UDP multicast) into RF signals including QAM, ATSC, DVB-T, ISDB-T, NTSC, or PAL. This technology enables IPTV streams to be distributed over coaxial networks, preserving video quality while ensuring compatibility with traditional CATV infrastructure. Perfect for multi-channel IPTV operators – surveillance systems – and large-scale broadcasting.
