Question and Answers

Question:
Will the H-THUNDER-4 modulate all 4 HDMI inputs on the same rf carrier? We are looking for a way to modulate multiple HDMI on one rf-channel any ideas. We don't need anything but rf out ok we have different 4 or 12channel unit available

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

Question:
Is the broadcasted RF channel will be able to be picked up by a tivo? Does the Tive have QAM or ATSC tuner?

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

Question:
We are looking for model recommendations for equipment to distribute CATV (QAM 256) within our minor league facility. Rough specs below: Convert 28 HDMI or 28 SDI HD Video sources into QAM Coax channels Distributing 28 QAM channels – in the clear, no encryption over the view to multiple locations From head-end rack to eight data closets ranging from 300’ to 1500’ cabling distance Infrastructure fiber is a single model with LC connectors. (know we need jumpers to SC/APC or other) Want to use 1310nm to preserve other wavelengths for possible future CWDM of DirecTV signals At each data closet, fiber receiver will feed 8-48 TVs via taps, copper coax. Prefer wall field mounting for closets, rack mount for the head end. Also, I want to know if the transmitter you recommend would be compatible with the Foxcom AL5R receiver since we already own a few of those from a previous project. (AL5R carries five DirecTV signals plus CATV. For now, we only need the CATV output)

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.

Question:
I have helped Jared with setting up the new modulator. It works fine but there is an issue which I like to correct.. At the UOO are also 2 older H-AC3-CMOD-QAM modulators. On these modulators, it is possible to set the minor channel number to 0 (zero). That is not possible on the new Thor-broadcast modulator. When the minor channel is set to 0 then the channel numbers shown on the TVs are 2 ; 3; 4 etc. The programs coming from the new Thor-broadcast modulator have the number like 5-1; 6-1 etc. I cannot find a way to change that. If I try to set the minor channel number to 0 it gives a message that 0 is not allowed. Is it possible on new Thor-broadcast H-THUNDER-4 modulator to change it another way so that on the TV's only the major channel numbers are shown?

Answer:
There is a trick in DVB-C Annex B QAM modulation Please set Major channel to 1008, and the TV will show only the minor channel, so for example if you need to show ch 20 , put 20 in minor Ch#

Question:

Need to modulate an HDMI signal onto an existing HRC cable system. I need to insert a channel into the existing cable tv system.

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

this is the least expensive option; easy to use, and compact, excellent product for the price https://thorbroadcast.com/product/petit-hdmi-rf-modulator-1.html

looks good. is HRC and QAM same thing?

https://thorbroadcast.com/product/networked-hdmi-hd-video-to-coax-digital-rf-modulator-with-8230.html

That unit is similar but also includes closed captions

https://thorbroadcast.com/product/1-hdmi-ypbpr-hd-digital-tv-compact-modulator-qam-atsc-8230.html/25 and this unit is the compact model with the highest grade encoding chipset we offer outputs up to 1080P60fps

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

Question:

I'm looking for a solution that will let me connect multiple TVs to a cable box

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

https://thorbroadcast.com/product/hdmi-fiber-extender-with-ir.html

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

https://thorbroadcast.com/product/petit-hdmi-rf-modulator-1.html

each TV can receive COAX cable instead of fiber

Question:

With regards to the specification of that model, - 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) Do you mean the modulator supports up to eight RF channel? And each of the 8 RF channels could carry the corresponding SDI input sources? (if the device has 8 SDI input, each of 8 channels will have 8 SDI sources) We need digital modulation. Could you quote for DVB-C, DVB-T, ISDB-T, please provided options for DTMB. SDI input is 2/4/8. Three options. In fact, what the standard configuration for the unit?

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

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

We have other models 1-12channel, but there are more expensive because they also have IPTV outputs besides modulated RF output

Question:

We had a great call with the customer yesterday there are very happy with the H-THUNDER 4 HDMI QAM HD modulator video audio quality and they were pleased with our work but introduced a new desire. They want to be able to stream live audio & video from a smart-phone directly onto the second modulated channel. Do you have a box or way to do that?

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:

https://thorbroadcast.com/product/compact-ip-decoder-set-top-box.html

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.

Question:

I am looking for a low cost rack mount modulator to take the hdmi output of a cctv system and broadcast it over one channel. Do you have such a device?

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

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

https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/122

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.

Question:

Channel Insertion for Comcast Set top Box. We have a customer that is looking at this. Will it support a channel like 1979? Any idea? I'm not totally sure what they are trying to do either.
OK. That's good to know. But I see in Thor's description that it handles channels 2 to about 139. Our channel is 1979. Should it still work?

Since we are able to push content from video cam successfully, I'd think it shouldn't matter what channel it is. Someone COMCASt must direct it to the right channel.

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.

Question:

we built a new home but didn't install one coax TV outlet box where it's needed, as we discovered upon move-in. We also removed DirecTV and HughesNet satellite dishes and installed an HDTV Antenna. My problem is, without the DirecTV box, I can't get the HDTV signal to one of my TVs without running a new coax cable to its location, which would require drilling through ceramic floor tiles.

Can you recommend a high signal-quality converter box to convert HDTV coax to a signal that can be transmitted and received to a Samsung Smart TV so I don't have to run another coax cable? The TV is located in the same room/area but not close enough to easily run a cable.

If the converter uses RF output, please recommend suitable transmitter and receiver boxes. Or if HDMI output please recommend suitable transmitter and receiver boxes.

My goal is as stated, high quality HDTV signal transmission from a coax wall jack to a Samsung Smart TV without running a new coax cable (which would be the simplest solution but require drilling through ceramic tile flooring).

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.

Question:

Can you also please advise on what the recommended RF amplifier is for this solution?

We are confirming what our current output level is but believe we will need to add around 10-15 dB.

Answer:

Yes we have RF Amps in stock.

Question:

I am looking for a solution for our TVs at a hotel. Presently we have set-top boxes looped via their RF out port and the last one connects to a CATV signal amp that sends the signals from the set-top box to the TV sets in the rooms. This causes TVs to be snowy. Am looking for a solution that can convert HDMI signals to an IP stream that can be sent to the TV via LAN. What products do you recommend I get? We have a total of 136 TVs and need up to 16 HDMI sources

--------

2

Thanks for the prompt response. Am not too sure whether the decoders have a built-in IP decoder. How do I check? We are using the Hisense 40A2g series smart tv 40 inches.

If the TVs don't have built-in IP decoders my plan was to use the IP to QAM edge modulators that I saw on your youtube channel that was paired with an HDMI to IP encoder.

Currently, we have 8 HDMI sources but I would like to grow that to 16.

And would like to make 16 channels

All the sources are coming from STB and don't have CATV services being delivered via cable. In this part of the world, all TV content is delivered via STB.

Lastly, the best quality video is preferable.

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?

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

Question:

what is the difference between ATSC and QAM modulation and how to convert HDMI to Coax using encoder modulator

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.

Question:

Qhat is the best HDMI encoder QAM ATSC modulator

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).

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

Question:

We are using this modulator to extend video to a legacy coax system connected to multiple TVs within a large meeting facility. The facility has a separate sound system. The signal from this modulator is close to a second behind the audio from the sound system. Is there any way to adjust/lower the quality of the video signal on the device to reduce the delay we're seeing? Any suggestions to address that delay through this modulator? Any help you could offer would be appreciated.

Answer:

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

Question:

Thank you so much for the follow up. We install security systems in residential and commercial applications. Sometimes we use hdmi video extenders from point to point but if you have a solution from lan to wan at a remote location that would also work.

We can send vga or hdmi signals. I would also like to discuss an hdmi petit unit we purchased for a residential bldg that serves about 65 apts. So far it’s working great but due to the old wiring infrastructure in the bldg some units are not receiving the camera signals. No fault of your modulator I know some wires have been cut ever the years since it was from an old master antenna system that was abandoned for many years and no with the cut the cord movement some residents are trying to use it again.

So that’s how I ran into this device maybe it will allow us to use lan to wan or vice versa to solve some of these problems. Please advise

Answer:

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

2)

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

Question:

Hi, we are MMX Technology, a design and system integrator company based in Italy and for one of our clients we have been contracted to design and install a video system upgrade for an existing broadcast center on board of two cruise ships. The systems on both ships ar identical and the current configuration was originally made using Drake and Blonder Tongue AV modulator (CV and Stero audio IN and QAM Coax out) and the distribution is NTSC over coax . We must keep the original Coax back bone but the inputs will all be upgraded to full hD with a combination of HD/SDI and HDMI. I am looking to change all the modulators with FULL HD input models

Answer:

We have done quite a bit of business on such ships and seafaring vessels; in this particular case it would be helpful to know how many HDMI and how many SDI inputs you require.

We have quite a few options to choose from in full HD modulation, in this particular case I would urge you to take a look at this product that might be a perfect fit for your needs.

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

This model has 8 HDMI inputs and 8 SDI inputs; the total capacity is 8 outputs so you can pick and choose how you want to split up those 8 inputs between HDMI and SDI.

This flexibility along with the built in modulation standards make this a universal device ready to deploy anywhere in the world.

Question:

I was hoping you could provide a summary of what was causing the issues at Sunriver. We hope to use Thor at more sites and want to make sure we understand the seatings needed with this HW configuration ( Thor’s with combiner)

Can you provide instruction on settings we need to be aware so we can use this on a guide for us.

Answer:

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

Question:

The Thor have an IP multicast to RF modulator that you would recommend?

Answer:

Yes, we do have UDP multicast IP to 16 or 32 QAM gateways available, in stock.

This is the link:

H-IPRF-16QAM

https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/122

H-IPRF-32QAM

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

What is the total number of streams that you need to modulate?
Are the streams encoded in MPEG2 or H.264?

Question:

Do you offer a IP gateway that can decode IP Cameras (Traffic cameras in a traffic management system) and output QAM RF? Better yet, output = QAM RF and IP, Do you offer a gateway to grab local ATSC 1.0 off air channels and output to QAM RF (better if output = QAM RF and IP). I’m needing to put together a system that will comprise of

Flip Qty-48 traffic cams to QAM RF (better if RF and IP)

Flip Qty-4 off air ATSC 1.0 channels to QAM RF (better if RF and IP)

How much of this solution can Thor provide? Do you offer an IPTV decoder box? (to install with a traditional TV with HDMI input). I have not idea the needed qty at the moment so just give me Qty-1 pricing and I wll scale from there.

Answer:

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:

1) - Decode each stream to HDMI

H-IP-HDMI , link ; https://thorbroadcast.com/product/4k-hevc-ip-and-usb-hd-video-decoder-ip-8230-1.html

Or

IP STB;s H-STB-IP Link: https://thorbroadcast.com/product/compact-ip-decoder-set-top-box.html

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.

Question:

For some reason the French channels are able to have the CC without any issue but any English channels not. By activating the CC on the receivers, the CC is working fine with no issue.
The idea is not to have the CC on all the time but for the customer to be able to activate it on they’re television.

Answer:

The main question is, does the CVBS output from the STB carry CC on line 21?

It is relatively easy to confirm.

You can take the RCA yellow CVBS signal from the STB and connect it directly to the TV.

If you can use the remote control to turn CC on/off and see the closed captions displayed, then the CVBS carries CC on line 21. If not, then it doesn't carry CC.

We need this CC data from line 21 to encode it into the RF channel. It is essential to have a CC source in order to pass it to the RF output.

Having a CC source is a prerequisite for us to proceed with encoding it into the RF channel.

It doesn't matter whether the CC is in French or English; what's important to us is whether CC is present or not.

Could you please perform this test and let me know the results? It should confirm whether the CVBS output carries CC on line 21.

This is how it works :

The Closed Captioning (CC) data is sent on the analog CVBS (Composite Video Blanking and Sync) signal on line 21.

Line 21 of the analog video signal is specifically designated for carrying the CC information.

In the NTSC video standard, which is commonly used in the US and Canada, line 21 of the analog video signal is reserved for additional data transmission, including Closed Captioning.

The CC data is embedded within the vertical blanking interval (VBI) of the video signal, which is the non-visible part of the video signal between the frames.

The CC data is encoded using specific protocols and standards, such as the EIA-608 standard for analog closed captions.

This encoded data is then transmitted on line 21 of the analog CVBS signal

Please review let me know if this is clear and if you have any questions.

Question:

I have learned my members really want Closed Caption when they watch TV.

So what is the most economical way to distribute/modulate 8-12 TV signals with Closed Caption?
Recall I have the H-16HDMI-RF-AMOD at my current club.

Answer:

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.
