8 x ISDB-T Tunners to IP model description
8 ISDB-T to IPTS gateway. 8 Independent off air ISDB-T input to IP TS SPTS multicast or unicast outputs. PN H-8ISDBT-IP Each TS program - "subchannel" from any ISDB-T Channel can be converted to IP stream - UDP/RTP/RTSP

RF to IP Gateway

Broadcast FULL HD IPTV content from 8 TV frequencies that can be ATSC / QAM / DVBS-S2 / ISDB-T / DVB-T

AIR / Cable / SAT to LAN & WIFI IP Devices

EXAMPLE Model numbers can be ( H-8QAM-IP ---- H-8ATSC-IP ---- H-8DVBT-IP )

In today’s digital RF, each 6Mhz channel off air ATSC (8VSB) or CABLE TV QAM channels can contain many TV programs. For example 57Mhz is Ch #2, it can have programs 2.1, 2.3, and so on. This unit can convert all the TV programs inside the 8 frequencies and convert it directly to IPTV multicast or unicast, as well as, MUX'd ASI output. Unit features 2 ASI inputs as well, so it can be a multi ASI input to IP Gateway too.

  • Converts 8 Antenna RF (off air) or cable Frequencies (channels) / ALL Received TV Services from each > TO > IPTV Streaming SPTS
  • Output up to 45x spts RTP/UDP multicast streams you can receive on any computer, tablet, mobile, IP decoder

The 8 RF Tuner Input Multiplexer is the latest demodulation and multiplexing device for digital TV broadcasting head-end system with TS output through ASI and IP port. It can multiplex up to 8 channels tuned and 1 ASI input to one MPTS.This multiplexer has the functionality of supporting auto-generation of PSI/SI information, PID re-mapping, service filtering and PCR adjusting. This unit offers to be used in either MPTS format or SPTS allowing you to aggregate all your programs from the tuner, or parsing them through selection options in the program menu to customize the IP output. This units incredible integration and cost effective design make this device readily available is now widely used in the Next Generation of CATV Broadcasting system.

This is the simplest way to convert existing RF Channels to IP streams in a clear and direct manner, this unit does not encode, it is just a gateway so if the incoming cable QAM channels are MPEG2, then the output IP channels will be MPEG2, same goes with H264 as well. This is an easy to grab OTA or QAM frequencies and directly convert them to RTP/UDP Streams to an existing IPTV channel lineup


RF to IP Gateway + RF Transmodulator

Take existing Broadcast RF channels and convert them to IP streams PLUS convert them to RF channels

This unit can take existing ATSC channels and convert them to IP streams and QAM RF channels simultaneously (RF input = IP + RF output)

RF Inputs can be ATSC / QAM / DVBS-S2 / ISDB-T / DVB-T

RF Outputs can be ATSC / QAM / ISDB-T / DVB-T

EXAMPLE Model numbers can be: (H-8ATSC-IP-8ATSC ---- H-8ATSC-IP-8QAM ---- H-8QAM-IP-8ATSC ---- H-8QAM-IP-8QAM --- H-8DVBS-IP-QAM)

This gateway and transmodulator is a unique device that can easily convert existing RF streams, up to 8 frequencies and convert to IP and RF channels. This will allow you to add any RF to existing RF channel bank as well as create IP streams for easy access via LAN. For consideration you can convert DVB-T to IP and QAM, or you can convert ATSC to IP and QAM, or also use it as a translator so you can take 8 QAM frequencies and convert to IP and 8 QAM (different frequencies, if you like to rearrange your channel lineup). The vast array of options make this an ideal headend piece to quickly and efficiently become more dynamic, add free OTA channels to a QAM headend, or simply create a RF to IP gateway with existing RF programs. This is the exact same unit that is mentioned above with the added benefit of transmodulation, we can essentially mix and match any RF to any RF with a couple exceptions. Please contact your local dealer or Thor directly for more information.

Question and Answers

This is the perfect solution for you : 8 x ATSC or Satellite Antenna Tuners to IPTV & ASI Output H-8QAM-IP H-8ATSC-IP Or this one 4 X Satellite or ATSC IRD Decoder to IP, ASI H-IRD-V4-ATSC H-IRD-V4-QAM this is a link : 

We have 16 RF tuners to IP and 16 tuners to IP + RF Out
They can be configured and ordered with different modulation type tuners.
One group converts RF to IP only
The second RF to IP and RF out ( it works as an IP gateway and RF to RF Transmodulator )
Please find my answers below:
I need a device that will intake the OTA signal and convert it to QAM output.  Need 16 or 32 QAM.
the best unit to do that is
H-16ATSC-IP-16QAM :  16 ATSC to 16 QAM and IP out
Also, I need information on the 16 QAM to Ip and product for OTA signal to QAM
H-16QAM-IP -   16 QAM to IP Gateway 
OTA signal to QAM
H-16ATSC-IP-16QAM :  16 ATSC to 16 QAM and IP out
Yes the ideal product for QAM to IP , the unit has 16 independent tunes ,i can be tuned to any QAM frequency, any program muxed on this frequency, will be available as a UDP multicast SPTS stream
Please check and let me know if that would work for you.
However unfortunately we do not make any Gateways that make Analog NTSC RF to IP.
For the analog channels, those would need to be decoded to CVBS video / audio or to HDMI  using Analog STB's and connect them to the Video Encoders like this one:
H-4ADHD-QAM-IP-LL 4ch CVBS or HDMI inputs 
4-24ch HDMI encoders :
