Q1 FTA to(DVB-S/S2 HD IRD QAM) RF Modulator

IP Modulator






Q1 is a high-density, modular and FTA professional TS processor equipped with 24 independent tuners, which can be either of DVB-S2 (up to 16APSK, 32APSK), ISDB-T, DVB-C, DVB-T/T2, DTMB, ATSC types, and option modulation (DVB-C/ DVB-T/ISDB-T/ATSC/DTMB) to convert Video/Audio signals into RF over exist Coax Cable distribution. It provides a best-of-class gateway platform for Digital TV Owners and IPTV operators.

Q1 DVB-S2, ISDB-T, DVB-C, DVB-T/T2, DTMB, ATSC Tuner to IP Gateway is a head-end interface conversion device and Routes Any or All Transport Streams via IP Output Port by 512*SPTS, N*tuner passthrough, and 4*MPTS channels simultaneously. It is integrated with tuner demodulation with ASI input and gateway function, which can demodulate from 24 tuners and directly convert the TS from DVB-ASI, then output the IP package through different IP address and ports.

Q1 enables an all-IP headend architecture, resulting in a more scalable and lower-cost transition to IP-based services. It distribute any HD and SD of unencryped Tuners Channels to unlimited TVs over the existing TV coax cables with real time perfect quality at any distance. This is an ideal solution for environments where you have a large number of air Channel, and used largely to Medium-Scale IPTV, Hotel, entertainment facilities, education broadcasting systems at schools and government buildings or any kinds of Source signals convert to Cable TV broadcast environments in limited budget severely.

Used in some of the most famous ballparks in the world, this is an ideal solution for environments where you have a large number of displays, such as stadiums, entertainment facilities, or broadcast environment. This DVB to IP Gateway is designed especially for high channel density environments where Rapid deployment, Easy management andcompatibility are critical.


Works both Coax Cable & IPTV networks: Distribute MPEG-4 AVC encoding to all kinds of Modulation and All SPTS/ MPTS Over UDP IP out.

Operation via LCD Screen and Web Management : easy to read LCD color front panel that makes it easy to setup and monitor your channels, check firmware, and identify IP addresses without a computer.

Multi-Modulation: Optional DVB-C (QAM), DVB-T (COFDM), ATSC-T, ISDB-T, DTMB Modulation (can selectable in web interface).
