Low Latency, HDCP Compliant HDMI, MPEG2 and H.264 Video Encoding, Dolby AC3 Audio Encoding
QAM, ATSC, DVB-T, ISDB-T Modulation
PN: H-4ADHD-QAM-IPLL
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.

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.
How you can use IP TV UDP output from the H-4ADHD-QAM-IPLL CATV RF modulator / IP encoder?
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.
https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0
3) If latency is not a concern, I suggest the H-THUNDER-8, an
8-channel QAM modulator with latency of about 500ms.
https://thorbroadcast.com/product/1-4-or-8-hdmi-digital-rf-encoder-modulator-8230.html/239
4) Here is the link for the 16 or 24-channel IP encoder with a latency of 800ms.

Yes, you can connect both the Gateway and the Encoder to the switch; it needs to be a smart switch with the IGMP protocol enabled.
The IGMP works in a way that it keeps the streams in the switch's memory and passes the individual streams to the specific port where the stream was requested by any IP receiver or decoder.
This is more detailed explanation how the IGMP works:
IGMP (Internet Group Management Protocol) is a communication protocol used to manage the membership of Internet Protocol (IP) multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish multicast group memberships. It plays a crucial role in enabling efficient network resource usage, especially for services like multicast video streaming. Here’s a simplified explanation of how IGMP works with multicast video streams and how it helps preserve bandwidth while allowing video access to anyone on the LAN network:
Multicast Streaming: Unlike unicast streaming, where a separate copy of the video stream is sent to each requester, multicast streaming sends only one copy of the video stream to the network, regardless of the number of requesters. This method significantly reduces bandwidth usage.
Group Membership: Devices that wish to receive a specific multicast video stream will join a multicast group. The multicast group has a specific IP address that represents all devices interested in receiving the video stream associated with that group.
Joining a Group: When a device on the LAN wants to start receiving a multicast stream, it sends an IGMP message indicating its desire to join a specific multicast group.
Multicast Router: The local router receives the IGMP join request. The router then knows that it should forward traffic for that multicast group to the network segment where the request originated.
Leaving a Group: If the device no longer wishes to receive the multicast stream, it sends an IGMP leave message. If there are no more interested receivers on the LAN, the router stops forwarding the multicast stream to that network segment.
Periodic Queries: Multicast routers periodically send IGMP queries to discover if there are still devices interested in the multicast group. If no devices respond with a desire to remain in the group, the router assumes there are no interested receivers and stops forwarding the stream to that segment.
IGMP efficiently manages network resources by ensuring that multicast traffic is only sent to network segments with interested receivers. This way, the bandwidth is not wasted on sending video streams to parts of the network where no device is interested in them.
In summary, IGMP facilitates efficient distribution of multicast video streams by managing group memberships, preserving bandwidth by directing streams only to interested receivers, and enabling open access to video content for any device on the LAN network that chooses to join a specific multicast group.
ust to clarify, the H-IPRF-QAM-32CH will accept the H.264 stream and pass it to the RF QAM. However, most TVs will not support this because MPEG4 (H.264) is not a US CATV RF standard; most TVs require MPEG2.
If you need to transcode just 4 streams, the easiest way would be to decode those streams to HDMI format and use a 4-channel modulator. You can decode IP using the H-STB-IP, and for the 4-channel modulator, you can use the H-THUNDER-4.

Based on your description, this is a very typical broadcast distribution architecture and there is a straightforward way to achieve it.
At the central distribution point, you can use our
Thor Broadcast H-4ADHD-ATSC-IPLL encoder. - https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/22
This unit accepts four HDMI program sources and multiplexes them into a single MPTS (Multi-Program Transport Stream) containing your four virtual channels, for example:
16.1
16.2
16.3
16.4
The encoder then sends this MPTS over IP to each transmitter location in your network.
Since each of your remote transmitter sites has a public static IP address, the encoder can simply transmit the stream using UDP unicast to all of the transmitter sites simultaneously.
At each transmitter location you would install our:
Thor Broadcast H-IP-ASI-B-V3 - https://thorbroadcast.com/product/asi-to-ip-and-ip-to-asi-converted-with-decoding-8230.html
This unit receives the IP MPTS stream from the network and converts it back into ASI format, which can then be fed directly into the ASI input of your ATSC modulator.
The ATSC modulator then broadcasts the multiplex as RF with the four virtual channels.

7 pcs H-4ATSC-ATSC-IPLL
7 pcs H-ASI-IP-B-V3
1. My modulator indicates that it accepts UDP unicast. Does your 4-ADHD send UDP unicast?
Yes. The H-4ADHD can output UDP unicast streams.
2. Can the 4-ADHD directly deliver 4 programs to my modulator as a one-to-one peer connection?
Yes. The unit can send either:
UDP Unicast streams (one program per stream), or
UDP Multicast MPTS, which contains all four transport streams in a single multiplex.
This allows flexibility depending on how your modulator expects to receive the streams.
3. Does the 4-ADHD allow both the ASI output and the Unicast IP output to be active at the same time?
Yes. Both ASI output and IP output can operate simultaneously.
4. I have a mix of ASI-only modulators that may require a unicast-to-ASI decoder.
That is correct. For modulators that only accept ASI input, you would use our IP-to-ASI converter to convert the IP stream back to ASI.
5. Pricing
Current pricing is as follows:
H-4ADHD-QAM-IPLL (4-Channel Encoder / IP Output) – $3,895
H-ASI-IP-B-V3 (ASI ↔ IP Converter / Decoder) – $2,995 - https://thorbroadcast.com/product/asi-to-ip-and-ip-to-asi-converted-with-decoding-8230.html
Your current system distributes television signals through a coaxial cable network to approximately 144 TVs throughout the vessel. The system was originally installed around 2012 and uses older analog modulators connected to DIRECTV receivers.
Over time, the system has developed issues such as:
Analog picture degradation (ghosting and noise)
Aging equipment
Limited flexibility for adding new sources such as cameras or additional channels
Moving to digital QAM distribution will significantly improve reliability and picture quality while allowing the system to expand easily.
We discussed using the Thor Broadcast Thunder-8 HDMI QAM Modulator, which accepts 8 HDMI inputs and converts them into 8 digital QAM channels distributed over coax.
Product Link:
https://thorbroadcast.com/product/8-channel-hdmi-rf-modulator-atsc-or-qam-8230.html
Multiple modulators can be combined to create larger channel systems such as:
16 channels (2 units)
24 channels (3 units)
32+ channels if required
Each unit operates independently and can be easily combined using standard RF combiners.
The Thunder-8 modulator works with any HDMI source, including:
DIRECTV receivers
Satellite receivers
Media players
Computers
Digital signage players
Other HDMI devices
The system encodes video using MPEG-2 QAM, which provides maximum compatibility with televisions used in United States, Canada, and Mexico.
Since your vessel already has a coax distribution network with amplifiers and splitters, there is a strong possibility that the new system can be installed with minimal changes.
In many cases the upgrade process is simply:
Remove the old analog modulators
Connect the digital QAM modulators
Rescan the TVs for digital channels
Digital QAM typically requires less RF power than analog, so existing amplifiers usually work without modification.
Some televisions onboard may be older analog or international models.
If a TV does not properly decode digital QAM, an external QAM set-top box may be used.
Example Decoder:
https://thorbroadcast.com/product/hdmi-qam-set-top-box-decoder-8230.html
These boxes convert QAM RF channels into HDMI output, allowing older TVs to continue operating.
You mentioned the vessel also uses a mix of IP cameras and analog cameras that may need to appear as channels on the TV system.
IP camera streams (H.264) can be converted to HDMI using IP decoders.
Example IP Decoder:
https://thorbroadcast.com/product/iptv-decoder-set-top-box-8230.html
These decoders output HDMI, which can then be connected to the modulator to create a camera channel.
Analog cameras can also be added using modulators that support composite video input.
Example Analog + HDMI Modulator:
https://thorbroadcast.com/product/4-channel-hdmi-av-rf-modulator-8230.html
This allows legacy cameras to remain part of the system.
Multiple modulators can be combined together using standard RF combiners or passive splitters used in reverse.
Thor Broadcast also provides RF splitters and combiners designed for CATV systems.
RF Splitters / Combiners:
https://thorbroadcast.com/product/1-x-2-to-1-x-128-fiber-optic-couplers.html
Typical CATV RF frequency range supported:
54 MHz – 1000+ MHz, which easily accommodates digital QAM channels.
Compared to the Technicolor COM3000 system , the Thor Broadcast solution should cost a small fraction of that amount while providing:
High-definition digital channels
Flexible expansion
Integration of satellite, media players, and cameras
Compatibility with existing coax infrastructure
