Overview:
OTV-EM24 4/8/12/16/20/24 Channel HDMI TO RF Modulator up to 24 HDMI sources from Satellite Receiver, PC, Blue ray, Local Playout, the latest new device which integrate encoding (MPEG-4 AVC/H.264) and option modulation (DVB-C/ DVB-T/ISDB-T/ATSC/DTMB) to convert Video/Audio signals into RF over exist Coax Cable distribution.
OTV- EM24 is designed especially for high density Distribution Video Engineering project, which can support rapid deployment, It distribute any HD and SD of HDMI Clear Video to unlimited TVs over the existing TV coax cables with real time perfect quality at any distance.
Overall Dibview's encoder modulators perfectly suit any professional AV company, including TV Channels, Live broadcasters, AV Installers and Integrators, Government applications, Hotel, Campus, Entertainment facilities, education broadcasting systems at schools and government buildings and many others.
OTV-EM24 can be 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 Video Modulator is designed especially for high channel density environments where Rapid deployment, Easy management and compatibility are critical.
