Product Description
Overview:
OTV-TM24 4/8/12/16/20/24 Channel Tuner To RF Modulator is a high-density, modular and FTA professional TS processor equipped with 24 independent tuners, which can be either of DVB-S2X/DVB-S2/S, 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.
OTV-TM24 4/8/12/16/20/24 Channel Tuner to RF Modulator is a head-end interface conversion device and Routes Any or All Transport Streams via IP Output Port by 256*SPTS 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.
OTV-TM24 4/8/12/16/20/24 Channel Tuner to RF Modulator enables an all-IP Head-end 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 Tuner to RF Modulator is designed especially for high channel density environments where Rapid deployment, Easy management and compatibility are critical.
