Product Description

Overview:


OTV-HM19 8 in 1 H.264 HD HDMI TO RF Encoder Modulator is an all-in-one device integrated encoding (MPEG-4/AVC H.264), multiplexing and modulation functions in one standard 1U case. OTV-HM19 Encoder Modulator can convert 8 HDMI signals and 1 ASI input to DVB-C/DVB-T RF out in the frequency range of 30~960MHz. OTV-HM19 is also equipped with 2 ASI ports and IP port to output TS.

 

The signals source could be from satellite receivers, closed-circuit television cameras and etc. its output signal is to be received by DVB-C/T standard TVs or DVB-C/T STBs.

 

OTV-HM19 Encoder Modulator can be used in public place such as metro, market hall, theatre, hotels, resorts, etc for advertising. OTV-HM19 Encoder Modulator also can be used for monitoring, training and educating in company, schools, campuses, hospital.
