Question and Answers
Answer:
No, the 4channel HDMI modulator H-THUNDER-4 has separate Channels for each input but it can be any channel, for example, 2,20,50 99, there is control of each individual channel. Do you need to Multiplex (MUX) all 4 TS programs on one physical frequency (One RF 6Mhz channel)? QAM 236 contains 38Mps data, so you can multiplex 4 programs encoded at 9Mbps each or 8 programs encoded at 4.5Mbps We have different 4 or 12channel unit available https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21 https://thorbroadcast.com/product/catv-rf-modulator-hdmi-multiplexer.html/37
Answer:
Yes, I just checked online, the Tivo has ATSC tuner, The modulator sends QAM or ATSC, it is selectable, it will be compatible with a Tivo
Answer:
The best way to convert 28 HDMI / SDI to QAM would be using H-HYBRID-RF-8 Modulator, it has 8 independent switchable SDI / HDMI inputs : https://thorbroadcast.com/product/8-channel-hdmi-and-sdi-clear-catv-rf-modulator-qam-8230.html For optical RF coax over a fiber we recommend to use the following devices : Fiber OTx https://thorbroadcast.com/product/32-mw-catv-rf-over-fiber-tx-45-870-mhz.html Fiber Rx Rack https://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html F-PLC-1x8 https://thorbroadcast.com/product/1-x-2-to-1-x-128-fiber-optic-couplers.html/226 The main thing I want to point out is that these are all 1310nm; will only work in the CATV band 45-870Mhz for QAM 256 If you are sending L-band (which is satellite TV) in the band 1400-2800Mhz I'm somewhat familiar with the Foxcom stuff, but I just checked the specs on their unit, it uses 1510-1610nm wavelength; so this would not be compatible. If you have different information then what I just read online then please let me know. We have similar, more sophisticated L-band gear https://thorbroadcast.com/product/6-ch-l-band-over-single-fiber-extender-54-3000mhz-cwdm.html And ours is not compatible with the lower band RF CATV gear because they operate in different bands, furthermore, you can not connect a CWDM receiver, like ours or Foxcoms, to a fiber link that is using a single laser, in the different wavelengths. Please give me a call if you'd like to discuss, if you'd like a BOM for the equipment above for a distribution system for point to multipoint let me know.
Answer:
 
 
Is the system QAM?
its Cox cable in Omaha, NE. I just know its HRC
Ok, and are there available channels you can use to insert into?
We need to verify, may need to delete a channel
I see
for now, just need 1 channel
Okay, well any of our Modulators will work, we have 1 Channel units that are compact, some are rack mount; they vary by chipset and various abilities
Will this be some sort of application like digital signage or will you play movies? Live Events etc?
digital signage type
Okay, then you can really go with any model and you'll be fine.
i see. does Thor have a channel delete item?
That's a bit more complex because you need an RF filter
so you'd have to specify which channel, and we make a frequency filter that would block the preceding program on that channel
ok. I know in the old days you needed to stay 2 channels away, but that was analog. is digital different?
I haven't seen a project come through that required such a device in a long while, but yes they still tell you to block out an extra channel on each side.
However I can have our engineers look into that for you to see what they can do
ahh, ok. can you send me some model numbers, non rack mount for now that i can look at?
sure
just the modulator for now
looks good. is HRC and QAM same thing?
That unit is similar but also includes closed captions
ok, nice
so HRC and QAM vary by one thing, and that's starting on channel one or channel two
however, both use 6mhz stepping in frequency modulation
i see
so reasonably speaking, so long as you don't use channel one; then any QAM product should work for you
Because when we discuss modulation, the biggest thing is the Standard, which is cable to ATSC
you have cable
Answer:
 
 
but I'm looking to be able to change cable channel from any of the TVs
I know all the tvs will show the same program, but I would like to be able to change the channel from any of them
ok
do you have anything that would do the trick?
we have modulators that can create your own channel from any HDMI source
so if the cable box is set to ESPN and you create it on channel 30
all the TV's in the house on channel 30 will see ESPN
But there is no way to change the channel from the cable box, without using a remote facing at the cable box
In order to do that you would need IR devices
ok, how hard is to install IR devices?
that would be up to the manufacturer spec
we do not offer those kinds of units
We only IR with HDMI over Fiber
what kind of fiber?
it is pre-terminated cable or can I use commercial fiber cable?
You would have to buy the fiber separately
LOL I do work with fiber cable, cool
those units are really simple to use, plug and play
but this is an extender only right? I don't see how can I connect multiple TVs
you'd have to send them individually
or you can use a modulator
and then buy separate IR products
ok, I have the cable box HDMI output right connected to what product? and from there to each tv with the extender
each TV can receive COAX cable instead of fiber
Answer:
RF output on each of the 8 RF channels can be individually set to a frequency and modulation standard (2 on QAM, 3 on ATSC, 4 on ISDBT, etc) - YES
Do you mean the modulator supports up to eight RF channel? -YES
And each of the 8 RF channels could carry the corresponding SDI input sources?- YES
We need digital modulation - THIS IS DIGITAL MODULATOR
 
AS I MENTIONED THIS IS UNIQUE MODULAULATOR IT SUPPORTS ALL WORLD MODULATION STANDARDS, included DTMB
 
 
We have other models 1-12channel, but there are more expensive because they also have IPTV outputs besides modulated RF output
Prices as follow
1 SDI modulator, H-1SDI-QAM-IPLL
2 SDI modulator H-2SDI-QAM-IPLL 
4 SDI modulator H-4SDI-QAM-IPLL
12 SDI modulator H-12SDI-QAM-IPLL
 
Answer:
So, it is possible but if it is not straight forward, it has to be done in a few steps.
 
They can set up a streaming channel on Youtube, they can stream to youtube form the cell phone then use IP STB to receive this youtube stream and output as an HDMI, the HDMI would be connected to the modulator.
The video might be delayed about 5 seconds this way.
This is the link to the IP STB:
 
The other way would be to dedicate 1 cell phone and equip it with direct HDMI output then streaming would be not necessary, but maybe a dedicated PC would be more reliable and convenient.
 
Answer:
 
All of our HDMI modulators can be found at that link, we have a few higher-end options and lower-end options
if you require rackmount, the least expensive One HDMI input modulator is this one
We have less expensive units in a compact format
 
Answer:
I totally understand your application, the main questions are:
What is the encoded format for your multicast streams? MPEG2 or H.264.
Since your Tuner and also most TV's tuners support MPEG2 only, that would determine if we can use IP to QAM Modulator.
This is a link to H-IPRF-16QAM IP to 16 QAM Modulator
 
If your multicast streams are encoded in H.264, we would need to take a different approach,
We would need to decode those streams to HDMI using IP HDMI STB's then use our 2 x 8l HDMI QAM modulators H-HDCAOX-8.
This is a link to IP STB with HDMI  H-STB-IP
 
This is the link to 8ch HDMI modulator  H-HDCOAX-8
 
Answer:
I attached the frequency chart for you, CATV RF QAM 139 physical channels,1979 is a Virtual channel, that means that comcast needs it to be on a virtual channel. Our unit supports that function. 
Each situation might be slightly different, we would need to program it and match the cable tv requirements, Customer would need to contact comcast and ask them following questions:
 

What is the frequency they require to modulate?
Do they require VCT, if so:
What is the VCT, major and minor channel?
What is a Service ID?
What is the Video and PCR  PID? do they need to be the same or different PID's
What QAM ? QAM 64 or QAM 256??
Do they allow HD resolution like 720p/1080i? , ( some companies like
Comcast allow only 480i SD resolution on Some STB's)

If you have some Cable TV  technician or engineer or Headend contact
information, you can forward it to us, we can try to find out for you
 
Once we get the answers we can preset the unit or help them set it up remotely.
 
Answer:

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.

Answer:

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
https://thorbroadcast.com/product/4-8-16-24-hdmi-iptv-streaming-8230.html/216
https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21
https://thorbroadcast.com/product/4-or-8-hdmi-inputs-h264-network-encoder-udp-unicast-multicast-rtsp-8230-2.html/33

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

Answer:

ATSC (Advanced Television Systems Committee) and QAM (quadrature amplitude modulation) are both digital modulation techniques used to transmit television signals.

ATSC is a digital television standard used in North America, South Korea, and other countries. It uses 8VSB (vestigial sideband) modulation to transmit digital television signals over the air or through cable. ATSC is a high-definition (HD) television standard, and is capable of transmitting video, audio, and other data using a single 6 MHz channel.

QAM is a digital television standard used in cable television systems. It uses quadrature amplitude modulation to transmit digital television signals over coaxial cables. QAM is capable of transmitting multiple channels of video, audio, and other data over a single coaxial cable.

To convert HDMI (High-Definition Multimedia Interface) to coax using an encoder modulator, you will need an HDMI to coax encoder modulator. This device converts an HDMI signal into a coaxial cable signal that can be transmitted over a coaxial cable.

To use an HDMI to coax encoder modulator, you will need to connect the HDMI source (such as a DVD player or cable box) to the encoder modulator using an HDMI cable. The encoder modulator will then convert the HDMI signal into a coaxial cable signal that can be transmitted over a coaxial cable.

There are several types of HDMI to coax encoder modulators available, including both analog and digital modulators. The choice of modulator will depend on the specific requirements of the application, including the distance that the signal needs to be transmitted and the data rate of the signal.

It is also important to note that HDMI and coaxial cable signals are not interchangeable, and a device is required to convert between the two formats. An HDMI to coax encoder modulator is used to convert HDMI signals into coaxial cable signals, while a coaxial to HDMI decoder is used to convert coaxial cable signals back into HDMI signals.

Answer:

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).
