8CH HDMI Encoder Modulator with Digital RF Output

8CH HDMI Encoder Modulator with Digital RF Output
support low latencyProduct OverviewHP848H8 in 1 EncoderModulator is an all-in-one device integrated encoding (MPEG-4/AVC H.264) multiplexing and modulation functions in one standard 1U case. It can convert 8 HDMI signals and 1 ASI input to DVB-C/DVB-TRF out in the frequency range of 30~960MHz. It 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/Tstandard TVs or DVB-C/TSTBs.In conclusion, its high integration and cost-effective design make this device widely used in variety of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.The device can be used in public place such as metro, market hall, theatre, hotels, resorts, etc foradvertising. It also can be used for monitoring, training and educating in company, schools,campuses, hospital.
