The signal source could be from any STB, satellite receiver, closed-circuit television cameras and antenna etc. Its output signal is designed to work with any TV or STB. Because it comes standard with every RF modulation standard builtin, this device can work anywhere in the world in a plug and play format.
This unit is similar to our popular line H-1,2,4 HDMI-QAM-IPLL product line, but it has some differences .It is less expensive unit, each program is modulated on its own frequency , CATV RF ouput only, no IPTV output

Gracias por la explicación. Esto es muy fácil, digamos que obtendrá 2 unidades de modulador HDMI de 8 canales, puede conectar 16 fuentes de video diferentes como reproductores de DVD, computadoras, satélite a cajas, Tomamos esos 16 videos HDMI y los modulamos en los diferentes canales de TV, ahora cualquier TV conectado a la red Coaxial puede escanear y recibir esos canales, Dado que esto será claro, canales CATV RF QAM sin cifrar, solo usará el control remoto del televisor para cambiar esos canales 1-16, supongo que actualmente tiene una red de Cable o Antena COAX en su lugar Por favor, avíseme si esto está claro.Podemos ofrecerle un precio de exportación con descuento de $ 3200 + envío para el modulador HDMI H-HDCAOX-8 de 8 canales, si toma 2 o más, usa un simple combinador pasivo CATV RF para combinarlos juntos .
The H-HDCOAX-8 outputs 8 separate 1 to 1
frequencies, but you can spread them, they do not have to be adjacent.
you can also create VCT like 11-1, 11-2 but on separate RF carries.
If you must have 2 on 1 the only way we can do it is through
H-4ADHD-QAM-IPLL, this unit can mux 1-4 TS's on the single carrier,
but the price is much higher

This is a smaller version of the popular H-HDMI-CC-RF unit which has HDMI Input up to full HD 1080p/60, supports QAM/ ATSC/ DVB-T/ ISDB-T modulation standards. All the Video / Audio encoding parameters and modulation channels are controlled via 10/100 Standard Ethernet and Web interface. This unit can be mounted vertically or horizontally on a rack mount cage panel for up to 12 units side by side.
QAM, ATSC, DVB -T, ISDB -T Modulation, Thor 1, 4, or 8 x HDMI Digital RF Modulator is an all-in-one device integrating MPEG2 encoding and modulation to convert audio/video signals into ATSC / DVB-C QAM DVB-T / ISDB-T RF output. Supports Low Latency Mode for live event applications, HDCP compliant, works with any HDMI source like DVD Player or Cable Satellite STB up to 1080p/60 resolution The 8-channel model in addition to 8HDMI inputs has also 8 CVBS baseband video inputs, which can be selected, those inputs could be also used for Closed Captioning Inputs.
