So if you do not have Coax at that one TV, do you have any other
cabling that goes there?

Maybe Ethernet Cable RJ45?
Then you can use this
https://thorbroadcast.com/product/4k-hdmi-over-ip-ethernet-cat6-rj45-extender-300-feet-8230.html

If you have Singlmode Fiber, you can use this
https://thorbroadcast.com/product/hdmi-fiber-extender-with-ir.html

You could ultimately use something like this
https://thorbroadcast.com/product/low-compression-wireless-hdmi.html
But the range is very short, if there are other TV's nearby there will
be a delay in signal as well.
Wireless solutions are only good for direct line of sight as well.

Thanks for reaching out.
Do you have TV's have built-in IP Decoders?
If not how do you plan on decoding the IP streams?
How many HDMI sources do you have?
How many channels would you like to make?
Where are the sources coming from?
Do you have CATV service that is being delivered via cable or STB to your hotel?

Also do you need MPEG2 or H264?
We have some encoders here that will work

We also have decoders here
https://thorbroadcast.com/products/rf-catv-and-iptv-ott-stb-s

----

Generally speaking no television sold over the counter would have this feature.
Did you go through an integrator or purchase through a vendor that
supplies its own Hotel software like Sonifi Solutions?

What country are you in?
Will you need MPEG2 or H264?

We can do the HDMI to IP, and certainly the IP to QAM; do you have the
available LAN in your hotel?
At what point would you want to do the IP to QAM conversion? Every
Floor? Or are there multiple sections of the hotel?

The more information you can give us the better

An HDMI encoder modulator is a device that converts an HDMI signal into a digital format that can be transmitted over a Coax cable network or broadcast over the air. This allows users to distribute high-quality video and audio signals to multiple devices or locations using a single HDMI source. HDMI encoder modulators are commonly used in commercial and residential settings to distribute content from cable or satellite boxes, video game consoles, or other HDMI-enabled devices to TVs or other display devices.

There are many factors to consider when choosing the best HDMI
encoder modulator for your application. Some of the key factors to
consider include:

Compatibility: Make sure the HDMI encoder modulator is compatible with
the HDMI source and the destination device. Thor encoder modulators prefer
1280 x 720p 59.94/60 or 1920 x 1080i/p 59.94/60 resolution and frame rate.

Data rate: Consider the data rate of your network or setup to make sure you
get the maximum potential out of your equipment.

Distance: Consider the distance that the HDMI signal needs to be
transmitted, and choose the method of output that is most suited for your run.
Some of Thor's devices have multiple output capabilities.

Quality: Look for an HDMI encoder modulator that delivers high-quality
video and audio.

Features: Consider any additional features that you may need, such as
the ability to transmit multiple HDMI signals on the same 6mHz band,
high capacity devices (24 channel Performux Encoder), support for HDCP
(High-bandwidth Digital Content Protection), and support for audio
formats such as Dolby Digital (AC3).

Our best and cost efective  4 or 8 channels HDMI modulatrs are H-Thunbder-4 and H-Thunder-8 .

We do have also 8ch HDMI or 8 HD SD SDI - selectable  modulators avaiable H-Hybryde-RF-8

The modulator needs time to process the incoming signal and encode it, but we do have a solution for it. Please use an external QAM tuner with HDMI and analog audio output. Now, use this audio as the source for your sound system. This way, the video and audio will be in sync

This is the link:

H-STB-QAM-ATSC

1. The Petti modulator outputs a relatively low RF signal, so you may need to use an RF amplifier or a stronger, more commercial type of modulator.

Examples:

40dB RF amplifier

As far as HDMI over LAN is concerned, it's easy to achieve using UDP multicast, and we have a very good almost plug and play solution for it.

For example, you could use the

TX side ) H-Spartan-2 HDMI to IP encoder: https://thorbroadcast.com/product/2-channel-3g-sdi-hdmi-h-264-ip-video-streaming-encoder.html

RX side ) You could use an IPTV STB for IP to HDMI conversion: https://thorbroadcast.com/product/compact-ip-decoder-set-top-box.html

3)

If you want to send HDMI over WAN, you can use the same solution and stream the video as HLS. However, this requires good network and streaming knowledge, and it's not plug and play. Specific setup is required, including access and setup of the router.

If you move encoder or decoder to different places, the devices must be reconfigured

Please let me know if this is clear

The modulator we were working on was set to the ATSC modulation standard, so I switched it to QAM.

It looks like the particular TV didn't support the CVCT virtual channel number standard; it was reading physical channel numbers and TS ID.

This is why we needed to adjust it. You will not have that issue often because the majority of TVs will support CVCT.

If you are using multiple devices and combining them together, all modulators must be set to QAM, and QAM channels cannot be repeated on any of the modulators.

Also, they need to be merged with similar +/- 5dB RF power.

I would suggest getting a good CATV RF meter/analyzer; it would simplify the installation process.

You would be able to see the carriers and determine if the levels are correct.

The easiest way to test the system is to take measurements directly after the combiner and do the scan there.

 If you can see all the channels, the rest is proper RF distribution.

Please note that most TVs are able to display channels at +25dBmv to 0 dBmV.

The RF amplifiers used in the system cannot receive an RF signal greater than +12dBmV.

You can always count on our technical support. We will always help to determine any issues

Are there cameras located on the LAN network or WAN network (public internet)?

Do they have the ability to output UDP multicast streams?


If your camera operates on the LAN (internal network) and is able to output UDP multicast, then we have a perfect solution.

The H-IPRF-16ATSC is an IP (UDP multicast) to 16 ATSC channels and IP-UDP output gateway.

 Please note that this is a gateway, so H.264 streams will not be changed to MPEG2. The modulator will carry H.264, so not all TVs may support that.

Link: https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/124



If your cameras are located on the WAN and stream with a different protocol than UDP multicast, then the only way would be to:
 

2) - Use ATSC modulators

For the ATSC modulators, you can use either the H-THUNDER-8 (8 HDMI to ATSC with no IP out) or H-4ADHD-ATSC-IPLL (4ch HDMI to ATSC and IP out). We could do it as a two-stage process.
 

H-4ADHD-ATSC-IPLL: https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/22

Your application is very straightforward, and we can provide all the necessary equipment from the beginning to the end

https://thorbroadcast.com/product/8-channel-sdi-and-hdmi-clear-catv-rf-modulator-qam-8230.html

https://thorbroadcast.com/product/1-x-2-to-1-x-128-fiber-optic-couplers.html/226

The HDMI video audio signal doesn't carry closed captioning data. You would need to turn on CC on the HDMI source, and then the CC will be part of the video. 

However, you will not be able to control it at the TV level because the CC will always be present as part of the visible video.

Another option would be to use a digital modulator. 

We have digital HDMI modulators like H-Thunder-8, which has a separate CVBS (baseband video input) as a CC source (yellow RCA cable).

 The CVBS video always carries CC data on the invisible horizontal line 21.

 So, two different cables need to be connected to the modulator - HDMI as the video/audio source and CVBS as the CC source. 

This way, we will encode CC as a separate data, and you will have CC control at the TV level.

The CATV circuits operate in a 75Ω environment. Most RF laboratories
equipped with standard test instruments employ 50Ω as the
standard interface impedance.
In this application note, it will be shown that:
dBmV = 46.9897 + dBm50Ω
dBmV = 48.7506 + dBm75Ω
dBμV = 60 + dBmV
dBμV = 106.98 + dBm50Ω
dBμV = 108.75 + dBm75Ω
dBmV and dBμV
Most CATV measurements are referenced to voltage and measured in dBmV or dBμV. In the classic
definition, dBmV is referenced to 1mVRMS and output voltage (VOUT ) is measured in mVRMS (Equation
 

We do have 16-channel HDMI analog NTSC modulators, but I would not recommend them for you because they are SD, and the video quality is like cable TV from the 80s. These are needed only in specific applications where customers have old analog tube TVs. So currently, the 8-channel HDMI is the most advanced modulator we have.

https://thorbroadcast.com/product/16-hdmi-to-analog-agile-catv-rf-modulator-ntsc-8230.html

There is another way to do it if you would have 24-135 channels to modulate. 

It is more complex; we can encode HDMI to IP streams using a 24-channel HDMI IP encoder, then use a separate IP to QAM gateway. 

https://thorbroadcast.com/product/4-8-16-24-hdmi-iptv-streaming-8230.html/216

https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/123

But I would not recommend it for less than 24 channels.

Please chek the table below :

Thank you for your inquiry. This is a relatively straightforward transition. You can use IRD's (unencrypted) or even Satellite STB's (Set-Top Boxes) with HDMI output and feed one or multiple 8-channel HDMI modulators instead of analog Holland analog modulators. The video quality will improve significantly.

Please check these 8-channel HDMI modulators; they are the key to producing digital QAM or ATSC channels that you can use for hotel distribution, just as you are currently doing with Holland.

You can use our IRD's if the signal is not encrypted; otherwise, you need to use Direct TV's or other satellite providers' STB's with HDMI output. We can use our IRD with encrypted signals, but you would need to have the provider's CAS Cards available.

Gracias por su consulta. Esta es una transición relativamente sencilla. Puede utilizar los IRD (no encriptados) o incluso los decodificadores de satélite (Set-Top Boxes) con salida HDMI y alimentar uno o varios moduladores HDMI de 8 canales en lugar de los moduladores analógicos de Holland. La calidad de video mejorará significativamente.

Por favor, consulte estos moduladores HDMI de 8 canales; son la clave para producir canales digitales QAM o ATSC que puede utilizar para la distribución en hoteles, tal como lo está haciendo actualmente con Holland.

Puede utilizar nuestros IRD si la señal no está encriptada; de lo contrario, debe utilizar los decodificadores de Direct TV u otros proveedores de satélite con salida HDMI. Podemos utilizar nuestros IRD con señales encriptadas, pero necesitaría tener las tarjetas CAS del proveedor disponibles.

I'm going to show you a quick demonstration of the new firmware we just developed for the Thunder 4, one of our most popular models. So, from our website, thorbroadcast.com, I'm going to give you a quick glimpse of that, and again, nothing else changed. We still have the NMS on the front. You have your power and link lights right here to show it's on. You can also set up these units using the D-pad and the buttons right here on the back. Very simple RF in, RF out for HDMI inputs. And you guys can read more about it here, look at some of the older videos, and obviously, at the bottom, PDFs manual.

Okay, so I just plugged in a Blu-ray player or DVD player; it is a Blu-ray 3D Samsung. So, I just plugged it into Port one; it's actually on this side. So, this is Port four. If you're going to the splash screen of the unit, this is 192.168.0.188. Go ahead and log into the unit; admin/admin. From here, you can see that this is a brand new unit out of the box; it already picked up the first HDMI input. Okay, so right from the status screen, you can see that I don't have anything else plugged in except for the first input.

Then you can click on the encode section, and you have all your inputs right here; two, three, four. So for the first one, you can change your bitrate from 525; you can set that out whatever you like, latency 500, 800,000. And we've received some different information about this; this is what we consider to be the fastest setting is 500, but in reality, I think it's probably much faster. There are certain things that pertain to that latency, specifically how fast the encoding is, meaning the resolution of whatever your input source is. So, something at 720p is going to go much faster than 1080p60. I think it's around 200 milliseconds, maybe even faster. But every infrastructure is going to be slightly different, depending on the TV, the receiver in the TV, and things of that nature. So, it's not a definitive, you know, fast, medium, slow, but you can set it up however you like. Again, this is just a ballpark figure. I think it's significantly faster than 500 milliseconds, in either case.

The next section here is AC3 for the audio, MPEG-1 Layer 2, and AAC. You have your TSID number, program number, program name you can change to whatever you like. This one I'm going to change to Blu-ray again. PIDs, your input source is just going to be HDMI on this particular model. And again, you see the status; it's on, it's spinning, and right here you can see we're at 1080i60. All right, make sure you hit apply to save your settings each time you change anything like adding in information. And if you change your sources or plug in different HDMI products, just press get, and it should just pop everything up here in the module eight section. Again, we're making this super easy, built-in attenuator for RF power. Your standards are all built in dvbt; this is nxa, which is European, generally speaking; atsc, that's American off an antenna. J3B is what we're using here for quam, and IDBT, which is another International standard. But you can set it up for quam or atsc, depending on what you're trying to do. Change your constellation, major and minor Channel, and again, on our website, you can go ahead and grab things like the quam chart and the atsc chart and look up your frequencies that you want to create those channels on. Use them major and minor channels, and it's that simple. And you can do that for each independent Channel; you can actually put each one, whatever Channel you like. All right, so it will take up the entire carrier; you can't put two programs on the same RF carrier on this model specifically. We do have other models like the H-4 ADHD that one will allow you to put up to four HDMI inputs on one RF Channel. With a thunder, you cannot do that; each one of these inputs will take up an entire RF channel. So, once you're done setting everything up on whichever channels you like, see as soon as I started putting in 57 MHz for channel two, this jumped to channel two, hit apply, it's going to save, and you're done. And that's it, quick and easy. The rest of the settings, your network password, you can change firmware and configuration, factory settings, save your configs. It's especially important once you're, you know, if you're in a setting where you might have 10 of these for 40 channels, you're in a hotel; you're going to want to save each one independently. God forbid all the power goes out or something like that. As soon as you power these back on, the settings will come right back into place, so it's important to save your config, you know, however you like in case you need them at a later point. But when you're going through the actual settings and you hit apply, that's good enough for the unit to remember what your settings are. Okay, and that's it, guys. If you have any questions, you can reach out to us at Thorbroadcast.com or call 1-800-521-8479.

For the 8 SDI inputs, we can use this modulator here: https://thorbroadcast.com/product/8-channel-hdmi-and-sdi-clear-catv-rf-modulator-qam-8230.html

How are you receiving the 10 sky channels and 4 freeview channels? Do you have HDMI output decoder boxes?

Or is the feed coming from a satellite dish?

Also do you intend to send those channels around your building in DVBT or in QAM?

Yes we can send all those channels through your building together in one RF coaxial cable, but all those channels must be the same RF standard (DVBT or QAM). 

We can use a simple RF combiner for this part. 

The other part is taking those 14 channels and modulating them into one standard on different channels. 

If those 14 channels you receive with decoder boxes and have HDMI output; then you can purchase 2 of these models for converting to DVBT or QAM

https://thorbroadcast.com/product/hdmi-modulator-qam-rf-coax-output-full-hd-8230.html/239

We would take the output from those 3 modulators and combine them, then you just plug that coax into your building coax which will distribute the channels to your 15 tv's. 

I hope that makes sense. 

Yes we have some excellent options using Thor Modulators. 

Specifically in this case the best option would be to use the higher density Thunder-8 Modulator. This drawing is a great representation on how you can take 4pcs (32 HDMI inputs and 32 output RF channels) for easy distribution to every room.

Countless hotels, casinos, schools etc, use the same application and these models to build headends for the same application. As you can see the 4 modulators go into a small combiner, then that single RF COAX cable can be used with taps and amps etc, to distribute full HD 1080 signal to every room. 

We do have a solution for it.

You can decode those sound only QAM channels to analog (RCA) audio only using external QAM Tuner H-STB-QAM-IPLL and then use an HDMI + Analog Audio QAM modulator to encode and output QAM or IP

H-STB-QAM-ATSC link:

https://thorbroadcast.com/product/qam-catv-rf-and-atsc-rf-to-hdmi-decoder-stb-8230.html

The video will come from an HDMI source of your choice, such as a DVD player or PC, and the audio will come from our QAM decoder box, H-STB-QAM-ATSC

We offer two models that might suit your needs: (they outputs QAM and UDP multicast IP Streams at the same time )

• H-2ADHD-QAM-IPLL: 2 channels  - https://thorbroadcast.com/product/2-hdmi-ypbpr-hd-digital-tv-modulator-qam-atsc-dvb-t-8230-2.html

• H-4ADHD-QAM-IPLL: 4 channels  -- https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21

Please let me know if either of these models works for you,

Combining multiple modulators is simple; you just need to select different channels on each one and use a simple 2x1 passive combiner. 

The setup would be straightforward: 6 pcs H-Thunder-8’s combined together using an external 1x8 RF splitter/combiner, with the output connected to your distribution system.
Each Thunder-8 would be set to different channels, carrying a total of 48 physical QAM channels.

The CC can be injected through the CVBS port from your DirecTV receivers, allowing you to enable or disable it at the TV level. Some RF power adjustment may be required since your current analog RF system may operate at a higher RF level. Our modulators output at +38 dBmV, and you’ll lose about 11 dB with a 1x8 combiner.
TVs are typically able to receive QAM signals in the 0–35 dBmV range, so it would be good to know how much loss is in your distribution system.
 If needed, the outputs can be easily boosted at the initiation point or at remote locations.

We have several ways to achieve this. Please give me a call so we can go over the details and discuss the pros and cons of each option.

We can use fiber, coax, or IP. Since you already have an IP network, that might be the easiest route.
We offer a 16-channel ATSC-to-IP gateway, which essentially includes 16 independent tuners. Each tuner can be set to a unique ATSC channel (frequency), and each channel typically carries 3–5 transport streams (video programs). The unit converts each TS into its own UDP multicast stream, which can be distributed anywhere on your LAN (wired network)—note that Wi-Fi is not recommended.

From there, you can use our simple IP-to-HDMI set-top boxes anywhere on the LAN to display the content.
 

Alternatively:

1. We can convert the antenna signal to fiber and send it over a fiber link (depending on your antenna signal strength). - https://thorbroadcast.com/products/cable-tv-catv-rf-45-900mhz

2. Or we can use ATSC set-top boxes to decode each channel to HDMI, then feed those signals into our 8-channel HDMI modulators to send them over coax.

As you can see, we can cover this from any angle depending on your setup.

The unit generates 8 individual channels, and they are pre-coded even without an HDMI source. If the source is not connected, a static Thor logo will be displayed. Once you plug in the video source, the logo will switch to the video and audio from that source.

If you’d like to add sound on channels 7 and 8, the best option would be to use a device such as a satellite STB with a radio station or music-only output, and connect it as a static image with audio from HDMI.

Without an actual video image, the modulator will not recognize the source as valid, since it requires a video resolution to lock onto the signal. Please let me know if this explanation is clear.

Another option would be to use an external set-top box (QAM tuner) with an analog audio output. 

You can install it anywhere on the coaxial network, take the audio from it, and feed it into your speaker system. This way, everything would stay in sync.

H-STB-QAM/ATSC

https://thorbroadcast.com/product/qam-catv-rf-and-atsc-rf-to-hdmi-decoder-stb-8230.html

 I’m happy to provide clarification on your questions below.

1. Maximum number of programs per DVB-T/T2 carrier
   Using our H-4ADHD-DVBT-IPLL, we can multiplex up to 4 TV programs onto a single DVB-T carrier. The cost for this unit is $3995 each.

We also offer an 8-channel DVB-T modulator priced at $3,995, however this unit operates in a 1:1 configuration (one program per RF carrier) and does not support multiplexing.

1. Conditional Access (CAM / encryption)
   At this time, we do not support Conditional Access Modules (CAM) or encryption. All of our DVB-T/T2 modulation solutions are clear (FTA – Free-to-Air) with no content encryption.

2. Broadcasting on multiple frequencies
   Each modulator can output on one RF frequency per modulated carrier. Multiple frequencies are supported by using multiple modulators, each assigned to its own RF channel.

Please let us know if a clear, unencrypted DVB-T solution would work for your application, or if you need help selecting the appropriate model.

Glad to hear the modulators are working well otherwise.

For that long run, you likely need a high-quality line amplifier designed for CATV/RF distribution that can handle the full spectrum and maintain signal integrity over RG-59/RG-11.

The H-Thunder-8 modulators output approximately +35 dBmV per channel. Most TVs are able to receive signals in the 0 to +35 dBmV range. In your case, both RF power level and signal quality (MER) are being reduced as the signal passes through the RF splitters and coaxial cabling. The amount of loss depends on the splitter configuration, cable type, and run length.

You can review typical splitter and combiner losses here:
https://thorbroadcast.com/product/coax-multiplexers-splitters-combiners-f-type-input-output-catv-atsc-or-8230.html

There are a couple of things you can try:

1. Switch modulation from QAM 256 to QAM 64.
   QAM 64 is more tolerant of noise and attenuation and generally performs better over longer or older coaxial runs.

2. Add an RF amplifier on the affected leg of the network (where channels are not reaching).
   Please note that the RF amplifier must support low input signal levels, typically in the 0 to +8 dBmV range. Feeding the amplifier with too high an input level can cause distortion and additional channel loss.

These are quick suggestions to try first. If the issue persists, a CATV RF QAM analyzer would be very helpful, as it allows you to measure RF level and MER at multiple points along the coaxial network and clearly identify where the signal is degrading.  

Adam 
Understood. For those channel counts, the most cost-effective solution would likely be using multiple 8-channel HDMI RF modulators, specifically our Thunder-8 units.

Are you currently on our website? I can guide you to the product.

Alex:
Yes, I can pull it up.

Adam 
Go to thorbroadcast.com, then click the first category: HDMI RF Modulators. On that page, look for the 8-channel unit (Thunder-8)—it has blue labels showing 1, 2, 4, and 8 channel models.

If you scroll down, you’ll see an application drawing for a 32-channel headend, which shows four modulators connected to a combiner, with the combined RF output distributed through a splitter.

Alex:
Got it.

Adam 
So for 24 channels, you would need three Thunder-8 units.
For around 60 channels, you would typically use eight units combined together.

The system is very straightforward. We can pre-program the modulators before shipping, assigning specific cable TV channels to each HDMI input so none of the RF channels overlap. That makes installation very easy.

Each HDMI input becomes its own independent cable TV channel on the RF output.

Alex:
Perfect. The client already has coax infrastructure in place.

Adam 
That’s ideal. Do they currently have set-top boxes in each room?

Alex:
Yes, they do. Our goal is to centralize all those set-top boxes in an IT closet instead.

Adam 
Exactly—that’s the typical deployment. All set-top boxes are installed in a central rack, connected to the modulators, and the RF output is distributed through the building’s existing coax network. That’s how most installations are done today.
