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.

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

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.

3) If latency is not a concern, I suggest the H-THUNDER-8, an
8-channel QAM modulator with latency of about 500ms.

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.
