Low Latency, HDCP Compliant HDMI, MPEG2 and H.264 Video Encoding, Dolby AC3 Audio Encoding
QAM, ATSC, DVB-T, ISDB-T Modulation
The H-4ADHD-XXX-IPLL modulator family from Thor broadcast is designed to handle even more applications than any other 4 channel chassis system that has come before. This HDMI to COAX Modulator has all the previous award winning features found in Thor Broadcast Modulators'; as well as, several new additional functions for added applications and flexibility. Our HDMI to COAX Converter provides 5 full RF carrier outputs for generating channels from content ingested through the ASI input. Encoding in either MPEG-2 or H.264 is provided for 4 crystal clear video streams up to 1080p60 each.
Bitrate is fully adjustable from 1.5 - 19 Mbps, and a variety of audio codecs are available. Standard audio encoding in MPEG-2 AAC and MPEG-4 AAC are provided; as well as, a licensed Dolby AC/3 audio codec. Audio sources can be selected from either embedded HDMI or Analog AV RCA ports. For Surround Sound, digital audio inputs can be set to "pass through" mode to preserve 5.1 and 7.1 audio that is encoded already in Dolby compatible format. Two mirrored ASI outputs are provided for broadcasters for added flexiblity in distributing the content generated by the 4 encoders.
This HDMI to COAX Splitter is an ideal solution for Professional Stadiums and Live Events. Used in more Collegiate stadiums for sports and distribution than any other model.
Programs input via ASI can also be multiplexed and remapped to the ASI output, adding yet another function to the unit as an ASI multiplexer. IPTV is not neglected in any way. All four encoded programs can be mapped to unique IP address outputs and ports in either UDP or RTP format. The IP output can be configured to strip null packets to reduce network bandwidth or preserve the constant bit rate (CBR) packet stuffing normally preferred by television systems. All four channels can be independently configured for either multicast or unicast outputs. Closed captioning is supported on a dedicated analog 608 CC port with RCA connector, an industry standard for line 21 captioning systems. Any 720 or 1080 line standard video signal in either HDMI or Component YPbPr format can be used for each of the four channels. This box also supports 480i for older TVs over RG6 RF coxial cables. Just like all other professional Thor modulator chassis, this system can be configured with firmware for either QAM, DVB-C, DVB-T, or ATSC channel format output.

I intend to use this modulator for MDU Video insertion purposes.Will your this modulator work with the Comcast Set To Box, QAM channel 134 and display channel 1851,1852,1853,1854,1855,1855,1856,1857,18581859, 1860 or 1901. How to set it up. Can I MUX ( multiplex) 4 of those videos on the single RF frequency Channel carrier and have them as a sub-channels
Our 4 ch H-4ADHD-QAM-IPLL worked on the Comcast system as an inserted channel.
We have simple GUI instructions on how to set it up, we can percent it everything before the shipping, so it would be just plugged and play.
We have also other similar modulators for 1,2,8 and 12channels.
We have great flexible products and technical support
Please check those units for your reference

I'm working on improving my bases TV system. I'd like to be able to take a few laptops and display some PowerPoint slides. I'm looking at the H-4HDMI-QAM IPLL but don't know which one to go with. The ATSC, or QAM, or DVBt version. Can someone help me choose the correct one? We use a lot of the Blonder Tongue AMCM-860D's for our other channels. We are located within Phoenix, AZ.
- It comes up as cable.
That is an excellent choice, and for the RF output option you'd most likely go with QAM.
DVBT is a foreign standard, since you mention you're in AZ, that won't work for you.
ATSC is standard 8VSB Off Air Antenna; so modulators can be used in this standard if you have an antenna RF infrastructure and then would like to add some custom cable channels of your own. So QAM is your bet; my assumption is that is what your Blonder Tongue units are. Oddly enough I researched that model and it is actually NTSC; which is the old analog variety of RF. So I'm not sure if you can purchase those in QAM or ATSC or they are only NTSC. The easy answer to find out is if you go to a TV on premise and do a channel scan to find channels on the coax plugged in the back, do you do Cable Scan or Off air Scan?
- Okay so then they are QAM units. So the H-4ADHD-QAM-IPLL is the unit you'd want to select.
An IP TV UDP output from an IP encoder can be used in several ways. Some common examples include:
Overall, the specific use for the IP TV UDP output from an IP encoder will depend on the user's specific needs and requirements.
Please review the following options:
1) H-4ADHD-QAM-IPLL: 4-channel HDMI QAM modulator/IP Encoder with QAM
latency around 300ms and IP latency of approximately 800ms.
2) H-4SDI-QAM-IPLL: 4-channel SDI QAM modulator/IP Encoder with QAM
latency around 300ms and IP latency of approximately 800ms.
3) If latency is not a concern, I suggest the H-THUNDER-8, an
8-channel QAM modulator with latency of about 500ms.
4) Here is the link for the 16 or 24-channel IP encoder with a latency of 800ms.
