Question and Answers

Question:

1) I’m in need of a DMOD that would take clear QAM and turn it into analog (Ideally agile, so we can put it where we want). Do you have anything like that?

2) I need to demodulate one QAM channel wit one program and modulate it as a standard Analog RF NTSC channel

Answer:
1) How many QAM channels do you need to convert to analog RF?
How many TS's in one QAM?
2)
As I mention, this is the best choice: H-STB-QAM-ATSC
This tuner has QAM RF input, you can decode any program and it has also ANALOG RF output channel 3 or 4
If you need a different analog channel than 3/4 we would need to add an additional Analog Agile modulator as a second box. It would take the composite Video Audio from the first  STB decoder and output and agile RF analog NTSC or PAL Channel.

Question:

Background: I have DISH Satellite TV. It is a two-channel receiver. Coax delivers the signal from the antennae to the DISH box. Channel one goes to the family room TV via HDMI cable. This is the “main” channel.

Second channel goes to the bedroom via Cat 5 cable – about 60 feet up through the wall across the attic and down to a central panel. The signal is sent from central panel box to an outlet box in the Master Bedroom  via ? From box to TV via coax.

If possible, I want to convert the coax signal to HDMI. Is that possible with your device?

Answer:
Your hunch is correct. Our box is for QAM/ATSC; or CATV frequency in the band between 5-1000Mhz
You have a Satellite Dish, which is LBand, lives in the frequency 1-2Ghz; these are entirely different formats. 
If you have a Dish subscription account its best to call them for another box as they are licensed subscriptions; buying a box online can work in some cases if you still purchase a CAS card from Dish; but in our case the RF STB is for clear QAM or ATSC 8VSB, not a satellite signal for converting coax to HDMI. 

Question:

1) Will this device be able to replace the attached device? 

2) cable provider is xfinity. It doesn't appear to find channels when I connect the RF COAX directly to TV. I can seem to find if its ATSC or Clear QAM....what does that specify?

Answer:
Yes, it looks like it. So long as the box you have is ATSC or Clear QAM, then it will replace it.
Who is your Cable TV provider? if you connect RF coax directly to the TV and scan it, is it finding the channels?
2) I see, if you have Xfinity, means you're paying for service which Cable QAM, your service is more than likely which means you require that specific box from Xfinity in order to get your channels. 
 
Our units are Clear QAM with no encryption, used in different applications; the point is you should be contacting Xfinity for another box, because otherwise you won't be getting the channels you're paying for. 
 
 

Question:

1) Will this modulator decode the HDMI signal from a Directv receiver and modulate it in the clear or will the display need a STB to decode the signal?

2) RF Input Decoder? Are you referring to a normal QAM ATSC tuner or something else?

Answer:

1) Correct. Our units will modulate HDMI inputs and send out the signal as Clear QAM so no STB is necessary, so long as the televisions have RF input decoders built into them. 

2) Yes, generally speaking televisions have RF decoders/tuners built into them. Hence why you can plug in RF cable and get a picture without an STB, because they decode Clear QAM(cable) and ATSC(Antenna); which is what televisions have been using for decades; however I would point out that many new models of tv's coming onto the market don't have RF inputs anymore. 

 

Question:

We recently bought a new smart TV and we’re replacing an older TV that’s about 15 years old. We had it set up with a coaxial cable. This cable was able to put through the cable box, the receiver and the Bose speaker system as we have a surroundsound. The new TV does not have coaxial connection so I am looking for something to convert to HDMI. My question is do you have a tour converter with the three coaxial plugs and the HDMI in it and I’m wondering if that will work for us to put everything through with the HDMI

Answer:
This would be the correct box; so long as it has the outputs needed for your surround sound as well, this will take Coax RF and convert to HDMI. 
Let me know if you have any questions; you can purchase directly off of the website. 

Question:

Hello, do you have any of the HD Set-Top Box Tuner / Decoder ATSC QAM DVB-T
DVB-S2 in stock?  I have a newer TV that does not have a coax input.  Will
this work so I can make the cable work on the TV?  if so, can you please send
me a quote so I can make a purchase?  Thank you.
 

Answer:
We do have several CATV RF Set-top boxes supporting various modulation standards, although they will not work with the RF from your Cable providers.
They can decode CLEAR RF QAM only, cable companies send encrypted RF, so you have to use their STB's to decode the signal.
Those units can decode Off Air RF, because it is not encrypted.
Where are you located, what modulation standard is used in your location?

Question:

Can you connect the H-STB-QAM tuner box to an older analog TV via a matching transformer?

Answer:
In the Specifications you will see these 
 2) Decoding Clear CABLE TV QAM RF
QAM to HDMI
QAM to YPbPr
QAM to CVBS  - Digital to Analog conversion
***QAM to ANALOG RF CH 3/4 as a Digital to Analog converter  
 
So this will only work if your current QAM TS is CLEAR. 
image.png
The analog switch for RF out is on the back and you can toggle between channel 3/4
So you will input the RF on the back, and also take RF off the back; F-Type connectors are on the left hand side. 
Hope this helps! You can order directly off of our website if you like. Units are in stock. 

Question:

The customer (Videotron a cable caster) received it.
What they told me is that it works fine with off-air signals but what they were expecting to do is to decode analog RF QAM signals with it and it doesn’t work.
Is it normal? Is it just a matter of configuration?
Is the H-STB-QAM-ATSC able to do that? If not, do we have a solution that would do it?



 

 

Answer:
QAM and ATSC are both digital signals. The box you have is for digital RF. 
Analog RF is NTSC; this box can not decode NTSC. 
Not sure who got the idea it can do that, the only analog portion of that box is that it can do QAM to ANALOG on RF CH3/4 which is a switch on the back. 
 
IF they need QAM output then we have 2 steps solution, ATSC input to the STB, then HDMI to DHMI QAM modulator

Question:

Does this box compatible with all or most cable providers such as wow

Answer:

The cable companies encrypt their QAM channels, so you would need to use a particular STB which is supported by that cable company.
Our STB supports CLEAR QAM without any encryption.
The easiest way to check if your QAM is encrypted or not, please connect the CAble TV feed to your Tuner TV, if the Tv scans channels OK, then you have Clear QAM, if not your Qam is encrypted and you Must use Cable Tv STB.
There is no other way around it.

Question:

  We have a college campus customer who has a campus-wide cable system but now are having to buy smart TVs that don't have tuners. I'm looking at the H-STB-QAM-ATSC unit. Seems it would work for this application? What questions do we need to ask the customer before being confident? We've discussed some of your products before but have not become a dealer so might be interested in that as well for this and other projects.

Answer:
Yes correct, so new TV's that don't have RF tuners built in all have the same issue, if you have a QAM system in place for RF, you need a tuner to convert the signal from RF to HDMI. 
These boxes are exactly what you need. The only question you can ask if it's QAM or ATSC, but since its a campus wide circuit, I'm 100% positive it's going to be QAM. 
So you plug it in, do a channel scan on QAM (cable), then use the remote to change the channel to your desired preference. 

Question:

1) The RV Park I live in has cable tv, but my new vizio tv doesn't have a coax tv tuner. How can I get a cable tuner with hdmi connection to my tv?

2) It's an open qam.  My old tv was connected to it directly.  However when I'm traveling I have an antenna I use also

Answer:
1) If the cable in the RV park is either Clear QAM or it is Antenna ATSC, then we have a tuner box available. 
However if it's cable from a telecom, like Spectrum, Time Warner, Verizon Fios etc then you need to get a box from them. 
Can you confirm what kind of cable is being transmitted through the RV Park?
We can help with install via phone support as well. 
2)
Then that tuner I sent a link to would be ideal since it has both modulation standards. 
All you have to do is just go into the menu options and do a channel scan for CATV or OFF air when you go to a new park. 
Very simple and straightforward, solves all issues for you. 
Let me know if you would like a quote. Or if you like, you can purchase off our website. 

Question:

I have Comcast basic service with an older coax cable box. I want to convert the coax signal to hdmi and send it to another digital TV with a wireless hdmi connection kit. Will the Hd Set Top Box Tuner / Decoder enable me to connect the coax signal to the hdmi connection kit? And is it available to purchase?

Answer:

Since you have a paid service, Comcast, the QAM signal is encrypted
and the only way to get that signal is through their products. We only
offer Clear QAM or ATSC tuners.
You'd need to contact Comcast directly and get pricing for an
additional Set top box.

Question:

How to convert coax to HDMI and what ATSC or QAM STB does

Answer:

To convert coaxial cable (coax) to HDMI (High-Definition Multimedia Interface), you will need a coaxial to HDMI converter or decoder like Thor H-STB-ATSC-QAM . This device converts a coaxial cable signal into an HDMI signal that can be displayed on an HDMI-compatible device such as a television or monitor.

To use a coaxial to HDMI converter, you will need to connect the coaxial cable source (such as a cable box or satellite receiver) to the converter using a coaxial cable. The converter will then convert the coaxial cable signal into an HDMI signal that can be displayed on an HDMI-compatible device.

There are several types of coaxial to HDMI converters available, including both analog and digital converters. The choice of converter 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. A coaxial to HDMI converter is used to convert coaxial cable signals into HDMI signals, while an HDMI to coax encoder is used to convert HDMI signals into coaxial cable signals.

An ATSC (Advanced Television Systems Committee) or QAM (quadrature amplitude modulation) set-top box (STB) is a device used to receive and decode digital television signals transmitted over the air or through cable.

An ATSC STB is used to receive and decode digital television signals transmitted using the ATSC digital television standard. ATSC STBs are commonly used in North America, South Korea, and other countries that use the ATSC standard.

A QAM STB is used to receive and decode digital television signals transmitted using the QAM digital television standard. QAM STBs are commonly used in cable television systems, and are capable of receiving multiple channels of video, audio, and other data over a single coaxial cable.

Both ATSC and QAM STBs are equipped with a tuner that is able to receive and decode digital television signals, and a display interface that allows the signals to be displayed on a television or other display device. They may also include additional features such as digital video recording (DVR) capabilities, on-demand content, and interactive services.Our H-STB-ATSC-QAM is very unique on the market because display VCT - Virchual channel numbers correcty according to the SMPTE CVCT and TVCT standard.

Question:

I need 8VSB/ATSC 1.0 to HDMI. It looks like this unit has HDMI out but I don’t see any mention of the output format is in your information. Does this have HDMI out and is there a rack ou t available? How about lead time?

Answer:
Yes, those units can do ATSC to HDMI. They are RF demod specific. This is an RF STB, for RF demodulation to HDMI output and must be ordered in a specific RF modulation standard. 
However I would suggest these models H-STB-QAM-ATSC
They are much newer, and much less expensive. We have these in stock and ready to ship. 
Rackmount is not available, they are only made in compact format. 

Question:

I am attempting to run the signal from a "free over the air digital antenna" through a AV receiver then into a television. The antenna only has a coaxial cable that works great when connected directly to the TV. The AV Receiver does not have a coaxial input connection. Can I use one of your converters to convert the signal to HDMI in on my receiver and then either run component or HDMI to the television.

Answer:
Yes you can do that. 
However we encourage you to try our newer, modernized box, that has QAM and ATSC available H-STB-QAM-ATSC. It's also much less expensive at only $125.00
In your case, you would set it to ATSC for over the air antenna, coaxial input, and HDMI output. Comes with a remote and very simple to use; we have them in stock. 

Question:
I've been testing your ATSC STB for a little over two months and thought you may appreciate a little feedback. I have it located in a bit of fringe area (for a number of TV stations) in Central Florida and using an Antop AT-SBS800 amplified panel antenna indoors for RF input. Initially HDMI output was to a Sony 40" 1080p TV (bypassing it's internal tuner) and subsequently has been to a ViewSonic 86" 4K commercial display.
 
-- Overall, the unit has performed remarkably well and provided very consistent & quality video output with resolutions of 480i/p, 720p and 1080i/p. It's such a pleasure to have rock solid performance like this.
 
-- The remote has a very intuitive layout and the buttons have been consistently responsive with ~12 - 16 hours per day use.
 
-- The Menu options are well-organized and settings are clear & meaningful. During initial setup (the first day, Sep 5), I accidentally put the unit in PAL mode (screen went blank) and I didn't notice an external/physical means to factory-default the unit. So I carefully followed the button press sequences documented in the manual to navigate back to the setting and return it to NTSC mode. This is the definition of operational consistency in my humble opinion. ;-)
 
-- During initial channel scanning with the integrated Sony TV tuner, it usually takes 1 auto-scan followed by 2-3 manual scans each with slightly different antenna orientations to receive all desired stations. With the Thor STB, it took 1 auto-scan and 1 manual scan. Very strong performance right out of the gates.
 
-- The integrated EPG and Info menus are much nicer than the Sony and the addition of Frequency, Bandwidth and Signal Strength (Quality) to the Info screen are both a nice touch and very helpful. Thank you.
 
At this point, I'm very pleased with the unit and believe it's a great fit for this application. I don't anticipate any issues programming a universal remote to control key features and plan on purchasing a second unit as a spare. If you have time, I just have a few very minor questions:
 
1. My apologies if I overlooked this in the manual, is there a button (sequence) to display the additional pages of multi-page windows (i.e. detailed channel program descriptions) within the EPG and Info screens?
 
2. Is there sufficient storage space to add firmware code to automatically switch back and forth between DST and ST when DST is enabled?
 
3. Within the Favorites menu, would it be possibly to have the LCN displayed to left of the channel name instead of the internal channel numbers?
 
4. It would also be nice to have another Favorites category called "Show" or "Series" (or similar) in addition the existing ones.
 
I'm on firmware 20221026v1.0 and don't recall seeing a newer version when I initially received the unit, but my apologies if any of the above have been addressed in newer code.
 

Answer:

Thank you so much for your kind words. We believe that the STB is highly reliable and versatile, capable of serving a wide range of applications due to its support for Off-the-Air ATSC and DVB-C Annex B Cable TV modulation standards. We will respond to your questions soon.

Question:
Are there any adjustments on the HDMI RF modulator - Petites to audio sync?
We have a customer that is using audio fetch in the gym for Audio from the satellite boxes(Analog) over WiFi for iphone use.
He says the audio over the Audio Fetch system is ahead over the modulated picture.

Answer:
They have volume control but that's it. Our more high end encoders with all the bells and whistles have features like that because the encoding chipset can handle it. 
A model with a cheaper encoding chip won't be able to handle all the in depth features like that. 
 
The issue is he's pulling the audio directly from the STB, meanwhile our model needs to encode and modulate the picture; naturally that's taking longer to do. 
 
This is my cheap solution for sports bars that want to handle the audio from a Petit in realtime; our RF STB modulated to the same channel as the PETIT output, and pull the analog audio of our RF STB. 
 
The whole key to this solution is you need to pull the audio AFTER it's encoded and modulated, not BEFORE. 
Pulling the audio before the encoding/modulating means you're gonna get it about 150-300ms faster then the video. 
Encoding takes about 0.5 seconds. 
The only way to sync Video/Audio would be using an external tuner. 
The tuner would decode Audio at the same time as the TV's would decode Video
 

Question:

Our QAM RF system service provider has recently started migrating our transport protocol for QAM channels to H.264.  It has been on MPEG2, and now some of the older TVs are unable to tune in the H.264 streamed channel.

                I was looking at your ‘H-8TS-HWTC’ – “8 Program MPEG2 H264 Matrix Hardware Transcoder” unit for a solution to this issue.  Can this unit tune in QAM H.264 channels and output with MPEG2 transport protocol encoding?  Ideally, we would want to tune in the QAM channel with the ‘H-8TS-HWTC’ at H.264 and output ASI MPEG2 MPTS of the converted channels.  Potentially we could also provide an ASI H.264 SPTS channel and the ‘H-8TS-HWTC’ would take the H.264 channel and transcode it to MPEG2 and output to ASI SPTS or MPTS?

                I might be way off base.  Is there another device that you can guide me to that does what I want?  That is to tune in a QAM H.264 channel, transcode it to MPEG2, and output it to an ASI SPTS or MPTS, or a different QAM channel.  Let me know what your suggestions are.  Please contact me if you wish to discuss this.  Thank you very much!

In answer to your questions:

 

How many TSs do you need to transcode?

                Currently we will need to transcode 12 channels.

 

How many of these streams are encoded in SD (480i) and how many in HD (720p/1080i)?

                All of our channels are in HD (720p/1080i).

 

How may QAM channels do you have?

                We have 12 channels derived from QAM.  Our intended output stream is to a QAM CATV headend TV system.

 

How many TSs are muxed on a single QAM?

                Only one TS per QAM channel.

 

How many ASIs?

                Currently we don’t use ASI, but in this desired functionality it may be required to use ASI.  For instance to re-modulate the original QAM stream after transcoding from H.264 to MPEG2, it would probably be required to utilize an ASI stream to input into the QAM modulator.

 

How many TSs are muxed on a single ASI?

                Not sure.  It may be that we want to put as many on one ASI as can be put on it.  For instance if we supply a QAM with multiple channels, pulling off 6 or 8 channels into the transcoder frame, those could be placed on one ASI MPTS?  We use Drake MEQ1000B QAM modulators.  We would only want one channel per on the output QAM, but the input side can vary with requirements.

Answer:
Thank you for your inquiry. We have a few options to explore.
 
Here are a few questions to help us better understand your requirements:
 
* How many TSs do you need to transcode?
* How many of these streams are encoded in SD (480i) and how many in HD (720p/1080i)?
* How many QAM channels do you have?
* How many TSs are muxed on a single QAM?
* How many ASI's ?
* How many TSs are muxed on a single ASI?
 
Please provide us with the answers to these questions, and we will be able to provide you with the best possible solution.
---------------------------- 2

I have one more question: Is your application intended for local RF coaxial in-house distribution, or is it dedicated to a cable TV company? 

1) Based on your answer, the H-8TS-ATSC/QAM 8-channel QAM to IP and ASI transcoder might work for you. 

The unit has 8 inputs and can transcode 8 SD or 4 HD programs. Since you have 12 HD transport streams, you would need 3 devices, as each unit can only transcode 4 HD programs. 

Here is the link to the unit: H-8TS-ATSC/QAM Transcoder.


 

 

 

2) Another, less expensive option would be re-encoding. You could use 12 small QAM set-top boxes (STBs) we carry—H-STB-QAM-ATSC—to convert them to HDMI format.

H-STB-QAM-ATSC


 

 

Then, use our 8+4 channel HDMI encoder/modulators, H-THUNDER-8 and H-THUNDER-4, which output 8/4 individual RF channels, and combine them together.

H-THUNDER-8  -8 channel

H-THUNDER-4 - 4 channel

Question:

We currently have fiber optic t.v and we recently bought a receiver which is connected to a rf signal streamer who only takes HDMI, I was wondering if your product can help, we have have Spectrum t.v services and we don't want to switch to another provider for a connection issue.

Answer:
Unfortunately, our STB will only work with Clear QAM, so it will not be compatible with Spectrum or any other cable TV service.
You can easily determine if you have encrypted or Clear QAM by connecting the RF cable directly into your TV. If your TV finds channels without a cable TV STB, then you have Clear QAM. Please let me know if this is clear.

Question:

We are setting up a new control center for our transmission and distribution operators.   We want to provide a cable TV signal to the operators and the video walls in the new control room.  We have talked with our local cable TV provider and they really don’t have a solution for us.  We have purchased one of your H-STB-QAM-ATSC cable boxes to try and provide a HDMI signal into our video management system.  If we can get it to work they way we need, then we will add three more boxes.   The signal from the Thor box would feed into a four channel HDMI over IP encoder that will connect to our video management system.  That signal then will get distributed to the operator consoles and video walls in the control room.  The Thor boxes will be located in the server room, so we need to work out how to remotely control the Thor box.  We think we can use a remote IR control box to be able to change cannels over the network.  It would be extremely helpful if we could get the IR codes/map for the Thro H-STB-QAM-ATSC cable box.  Would it be possible for you to provide us with the IR coding map for the Thor H-STB-QAM-ATSC cable box.

 

The cable signal we currently distribution throughout our building is a Clear QAM cable signal.

 

Let me know if you have any questions or suggestions.

Answer:
Thank you for your inquiry. 
Attached is the IR remote control code for the Thor H-STB-QAM-ATSC cable box.

 
 
 
Please also note that we do have 4ch HDMI to IP encoders available if needed:
H-Spartan-4
https://thorbroadcast.com/product/4-channel-hdmi-cvbs-network-encoder-streamer-udp-rtp-unicast-multicast-8230-2.html
 
 
 
While this is a viable solution, I have a better option for you.
 
Instead of decoding the QAM signal and re-encoding it, you can go directly from QAM to IP using our Thor H-16QAM to IP gateway. This unit has 16 independent QAM tuners and will output all TS's available and muxed on those 16 unique cable TV channels. This way, you will get the original encoded streams, not a re-encoded "copy."
 
The H-16QAM to IP gateway has a user-friendly NMS GUI, allowing you to remotely scan any channel and convert it to a specific multicast IP address.

Question:

My client has a ZeeVee HDb 2540_NA QAM modulator. Will the H-STB-QAM-ATC Find the outputting channels?

Answer:
Yes, you are correct. The H-STB-QAM-ATSC does support Clear QAM, which is the format generated by the ZeeVee HDb 2540 QAM modulator.
 

Question:

Message: Cómo puedo conectar esta cajita de TV

Answer:

Hola 

Este equipo es un decodificador de señal RF (CATV QAM y antena ATSC) a HDMI. Básicamente, solo debe conectar la salida HDMI de esta cajita directamente a la entrada HDMI de su televisor.

Una pregunta importante: ¿en qué país va a utilizar la señal RF?
En diferentes países se utilizan distintos estándares de TV. Este modelo funciona únicamente con:

? ATSC (8VSB) para EE.UU., México y Canadá
? Cable TV QAM (J.83B)

Nota: Los canales de cable QAM deben ser sin encriptación (Clear QAM). Si los canales están encriptados, el equipo no podrá decodificarlos.

Saludos cordiales.
 

Question:

Does the H-STB-QAM-ATSC QAM/ATSC set-top box can output HDMI video to a TV while also providing analog audio through RCA outputs at the same time.

The customer’s use case was:

  • Receive QAM RF signal

  • Decode it using the H-STB-QAM/ATSC

  • Send HDMI video to a TV

  • Simultaneously use analog RCA audio output for an external audio system

Answer:

YES ! 

The H-STB-QAM/ATSC decoder supports simultaneous outputs.

When receiving a QAM or ATSC RF signal, the unit can output:

  • HDMI video and audio

  • Analog video (CVBS)

  • Analog audio (RCA L/R)

These outputs can operate at the same time, allowing flexible integration with TVs, monitors, or external audio systems.

Example Use Case

Signal Flow:

QAM RF Input
↓
H-STB-QAM/ATSC Decoder
↓

HDMI → TV or Monitor
RCA Audio → External amplifier or sound system
CVBS Video → Legacy display or monitoring equipment

Key Benefit

This allows installations where:

  • Video is sent to a modern HDMI display

  • Audio is routed separately to an external sound system

  • Legacy equipment still receives analog signals if required
