QAM modulator for IPTV backbone to Clear QAM RF

Thor Broadcast model H-IPTV-16QAM will modulate IPTV transport streams to Clear-QAM RF channels for DVB-C applications

The H-IPTV-16 QAM modulator is a simple all-in-one utility device to convert up to 1024 IP Transport Streams in UDP / RTP into 16 non-adjacent QAM Channels. This Thor Broadcast high-density IP to QAM modulator is designed to take content delivered via an IP backbone or CDN system and modulate the programming onto digital QAM cable channels for distribution over coax. This product includes a 1RU chassis supporting two individual Ethernet inputs injecting up to 840Mbps on each Ethernet RJ45 connector outputs all programming onto a single RF F-Type connector for easy output into your RF Coax infrastructure. This single RU form factor allows you create your own IPTV to RF headend in a single chassis. All QAM Channels and IP inputs are managed from the easy to use NMS RJ45 port connection on the front of the unit allowing you to quickly and easily access your programming from Thor’s easy to read GUI that can be accessed from anywhere on your network. The IPTV programming input is standard headend format, meaning basic UDP / RTP unicast/multicast IGMP v2 / v3 addresses and port format. This impressive density allows a single chassis to convert an IPTV Ethernet backbone feed to be converted to a full lineup of digital cable DVB-C channels for easy distribution. 

APPLICATION: 

In Addition to high-density IPTV-QAM modulators for any application, Thor also Specializes in Hybrid Fiber Coax (HFC) and Fiber to the Home (FTTH) equipment and system design. Thor’s full turnkey solution product line even extends to headend encoding platforms with the goal of being the only equipment provider you will ever need. A full staff of trained application engineers is available to answer any questions you might have and to recommend solutions available that you're not aware of. Contact a sales representative today if you would like more information on receiving a free consultation and system design.

 

Thor part number H-IPTV-QAM systems are specifically designed to utilize bandwidth to the incoming IP Transport Streams and reallocating that bandwidth on the RF QAM frequencies. The amount of programs that you are able to inject into the QAM systems is only limited by the bandwidth provided. Essentially you can create a lower amount of HD (High Definition) programming or an extensive amount of SD (Standard Definition) programming. This can even trasnport IPTV 4K streams and convert them to QAM cable channels. The 16 non-adjacent QAM channels are uniquely setup in the NMS so you can place them in any QAM headend that will allow programming to be set and configured in any channel lineup. With auto or manual PID remapping functionality, you’ll be able to set exactly the channel configuration of your choice allowing added flexibility to the customization of your channels. Maximizing these Gigabit Ethernet ports will allow input up to 840mb/s each producing 16 QAM Channels. Creating your own custom headend has never been easier using Thor Broadcasts newest IPTV to-QAM CATV headend in a box.

How to convert IPTV Video steams to Cable TV channels - IPTV to CATV QAM , IPTV to coax converter
So in today's episode, we're using a 4 Channel HDMI encoder modulator H-4ADHD unit that is creating several IP streams from HDMI sources. Those sources Roku, Firestick, and BluRay are then sent via RJ45 through a switch which then goes from IPTV streams, converted back to RF QAM using an EDGE QAM Modulator. This is ideal for campus-like environments that can use one headend to distribute IPTV channels to numerous buildings, and then break back out to COAX via QAM Modulation. High-density output means a single 1RU 32QAM output device, can let you put quite a few streams into the coax existing infrastructure without the use of Set-Top Boxes. links to the devices : 4channel HDMI IP encoder and QAM modulator : https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21 4 channel SDI IPTV encoder and QAM modulator https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0 Edge Modulator - IPTV streams to QAM modulator https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/122

Question and Answers

Question:

At my end, I am working on getting the Thor H-IPRF-QAM running. However, I cannot find my manual. So, do you have a pdf for it? I did try the website, but there is no link to a user manual for the H-IPRF-QAM. Next, can I get a link for the latest software and firmware for it? At my end, I have the snmp3.8.6, and while I have it looking for the modulator, it remembers the old settings, but I am not talking to unit.

Answer:

I just want to inform you that we have all new and much less expensive stand-alone IP to 16 or 32 QAM Modulator now H-IPRF-16QAM H-IPRF-32QAM

Question:
Do you have a UK distributor for your products in particular IPTV to 16/32 CLEAR CHANNEL RF QAM/ATSC Modulator?

Answer:
Yes our reseller in the UK is Jigsaw24, they will be able to quote you on anything you need. If you would like to purchase direct please let me know.

Question:
I'm interested in IPTV to DVB-T Modulator.

Answer:
The DVBT standard has a wider step in Mhz then ATSC /or QAM. So if you need DVBT the 16QAM unit will only output 8DVBT and 32QAM unit will only output 16DVBT. So essentially because of that modulation standard, the amount of channels we can output is cut in half.

Question:
We are interested in your IPTV to analog 16 channel rf output modulator. can your product accept IPTV multicast streams encoded in H.264 and convert it to Analog RF spectrum.

Answer:
Do you need IP to Analog RF NTSC/PAL modulated output? Can you accept Digital RF QAM/ATSC/DVB-T output? What country are you from, we will check your CATV RF modulation standard If you need Analog RF output than we would need to use the IP to CVBS decoder than Analog Modulator with CVBS Input. https://thorbroadcast.com/product/8-ip-to-8-analog-video-audio-cvbs-out.html

Question:
We are interested in the H-IPRF-32QAM but are unsure if it is compatible with the streams from our IP cameras. We have UniFi Video cameras that output streams in RTSP / RTMP / RTMPS formats. We have many IP cameras and trying to find the best way to distribute those videos across our facility over COAX RF cables to about 1200 TV's as a CABLE TV or Off the Air channels, We would like to also assign virtual channel names and virtual channel numbers, what would be the best way to do it ?

Answer:
This IP to QAM modulator unit supports unicast/multicast UDP and RTP Input IP TS streams only. Please check if those cameras have that format available, if not You can use our IP STB (set-top boxes) to decode your stress to HDMI Video format, this is a: https://thorbroadcast.com/product/compact-ip-decoder-set-top-box.html Now the HDMI QAM from the STBs connect to our 8Ch QAM/ATSC modulator to modulate and create 8 individual digital channels with the HD resolution up to 1080p https://thorbroadcast.com/product/1-8-hdmi-digital-rf-modulator-cc-closed-captioning.html If the cameras have HDMI outputs you could connect the output directly to the modulator, eliminating the need of the STB. Some cameras have other Video outputs like Analog Video CVBS or HD/SD- SDI, we have other modulators with those video format inputs

Question:
f I have maximum 1024 Channels TS over UDP, RTP & Unicast / Multicast, How do I assign these 1024 channels to 16/32 Clear QAM/ATSC Channel Outputs? If I have 16/32 Clear QAM/ATSC Channel Outputs, How can I connect and tune all these channels on a smart TV ? because in your drawing i need RF splitter output for each channel. These modulators are for a project of many hotels

Answer:
What modulation will you need QAM or ATSC, the unit support only one of them? For hotel application QAM is better to format, you can fit more videos too. How many IP TS's do you need to modulate? Please note that 1 QAM channel contain 38Mbps data, the 1 ATSC channel contains 19Mbps data, so the amount of the programs we can fit in 1 Channel depends on the encoding TS video data rate. For example, if your TS datarate is 8mbps, then you can fit 4 Videos on the 1 QAM frequency or 2 videos on 1 ATSC frequency because of the 38mbps limit for QAM. Please let me know if this is clear.

Question:
We have a requirement where we need to convert 250 IP channels to QAM modulation Once converted to QAM we need to send the QAM signal over Fiber to the other side and then reconvert to QAM from Fiber to the RF distribution I was suggested to use your IP QM32 but not sure if it had the capability to do these many channels

Answer:
Yes, this is what that equipment was designed for. It will output 32QAM Channels; if you need more then that you just purchase additional units. However you can also put multiple programs in a single QAM, that is determined by the data rate of each IP. For the RF over Fiber application, we have an entire catalog of units to get the project done correctly. https://thorbroadcast.com/products/cable-tv-catv-rf-45-900mhz What is the approximate distance of the fiber, or the optical loss of the line?

Question:

Is there a decryption option available? Our IPTV feed utilizes Veramatrix encoding so we would need to strip that off. Can the input IPTV be SD and HD? We would utilize a mixture of both.

Answer:
The H-IPRF-16/32 accepts a clear IP stream to CLEAR QAM, so the Vertimax needs to stripped off.
The unit is transparent, it works as a gateway, so whatever format is coming on the IP, it will be situated on the QAM.
You can also mux multiple TS programs on the single carrier, up to 28Mbps per channel, so for example if your streams are encoded at 8Mbps, you can fit 4 of them, For example, ch 2.1, 2.2, 2.3, 2.4

Question:

Do you guys have anything that could fit this need? “We have a large IPTV headend and we like to feed the channels to the Hotel and convert the IP to QAM or NTSC for the TV tuners to receive the signals” I need 64QAM channels

Answer:
We do have options for both. The QAM models are in stock; we have 16 and 32 channel outputs available. 
https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/122
So, you can use 2 units, and then use a simple 2x1 RF combiner and the output of the combiner will have all 64 channels. 

Question:

Thanks for the reply, we are looking at replacing our existing Vesima terrace units and expanding our hospitality product offering and believe that this product will meet our needs. However, since this is a new avenue of content delivery (IP/FTTX/multicast) for us, we want to ensure that the product will accommodate our needs. As such, is there an option available to bring in a demo unit or a try and buy the program?

Looking at the IP to H-IPRF-32QAM

The incoming streams would be clear UPD Multicast (h.264, aa3) in an SPTS MPEG2TS. Does the platform allow for muxing internally, or do we need to use MPTS?

 

Answer:
Are you looking for IP to 16QAM H-IPRF-16QAM or IP to H-IPRF-32QAM?
Are the incoming IP streams Clear UDP multicast streams encoded in MPEG2?
2----------
Yes, the system is able to mux internally, but please note that we can not transcode (h.264, aa3) to MPEG2, so if the multicast st stream is encoded in H.264, the same stream will be modulated on QAM.
A lot of TV's tuners will be not able to decode H.264, just a few companies and new TV's support H.264

Question:
I'm looking for a way to modulate a bunch of IP cameras, or at least I think that's what I want.  
 
Some background-  The installation is on an oceanographic research vessel.   Our old camera system, (which we just replaced), consisted of a dozen or so analog cameras, a cross switch, about 6 display/control stations and modulators for about a dozen channels.    The modulators fed into a simple coax-based antenna distribution system, with TVs in most of the cabins connected to it.   The modulators ran on the old channels of 2-13.   The old system was circa 1990
 
The new system is IP based, but otherwise more or less the same, a dozen cameras, 6 control stations, etc..   However, we are not presently modulating the camera outputs to anything.  What we would like to do is pick up the IP streams and modulate them for modern TV.   I believe that would be ATSC.   We would also consider QAM.  Basically, if I go to Best Buy and get a TV, I want to be able to see the output of our video cameras when I plug the TV into the ships antenna system. 

Answer:
We do indeed have EDGE QAM modulators that would be ideal in this kind of scenario where you need to convert IP streams directly to QAM or ATSC. 
Those units are very specific so you need to determine if you would like to do QAM cable or ATSC over the air antenna. 
So you should consider if you have any other programs or CATV channels running in your vessel, it would be easier to match whatever else is presently available.
 
IP to 16QAM 
https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/122
 
IP to 8 ATSC 
https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/125
 
Both of those units are the same price. 
 
Some questions I would have for you is in order for this to go smoothly we would need to know more about those IP streams you have. 
What is the protocol being used? I assume those are multicast streams as well but double check on that for us.

Question:

Please propose for IP to DVB-T. Please also note, our HD channels are between 7 – 15Mbps and the SD ones are between 3 – 7Mbps. We require a minimum of 400Mbps to accommodate channels. Therefore, please propose a compatible unit.

Answer:
The higest desinty we can offer for the DVB-T is 16CH
If you use a 6mhz channel then 19.4Mb payload x 16 = 310Mbps
If you use 8Mhz channels than 33Mb payload  x 16 = 528Mbps
The part number is H-IPRF-16DVBT

Question:

We’re looking at some of your IPTV to Clear QAM products and were wondering how similar it is to a Cisco RFGW-1.  I currently have 5 Cisco RFGW-1’s out in the field providing video overlay. We’re looking to get about 50-60 channels out.  Which device would be best suitable for this?

Answer:
Yes we have similar IP to Clear QAM gateway, similar to Cisco RFGW-1
 
H-IPRF-32QAM is a IP to 32 QAM gateway , it generates 32 QAM block channels
The unit is is transparent to incoming TS stream, so the TS on the IP input = TS output on the RF QAM
The streams can be put and mixed anywhere on the available and generated Channels
It supports VCT and PID's remapping, major and minor channels can be named for any stream
 

 

If you need 50-60 channels than 2 pcs would do the job

Question:

When you say transmitter and receiver set, that is making me wonder if I need to buy two to get things working. The primary use of this would be to take existing IP camera video streams and modulate the video feed onto a coax cable. Most of the models are Bosch IP starlight 5100i. I should be able to get away with just one unit, right?

Answer:
This is just a gateway, it converts IP to RF without changing the stream. 
Now that you mention you have IP camera's this probably won't work since you mention you're in Massachusetts.
 
Here's why; these gateways do not have any sort of transcoding implemented (yet, we're working on that)
So I went to the camera's data sheet and these are H264/H265 camera's. 
Which is great, if you want to use something like VLC to view the footage. 
Now if you're planning on using an american television with north american standards this solution won't work. 
You have to re-enocde the signal first. So essentially you need to take the camera outputs and put them in an RF modulator, which usually require IP STB's. 
You can't view H264 video on American MPEG2 televisions (for the most part, there are exceptions. 
 
We are working on a new model that has built in transcoding, however, that might be ready in 1-2 months time, it'll be the first of its kind on the market. 
For the time being if this is an immediate solution you require, you'd be better off purchasing IP STB's, so if you have 16 camera's, you'll need 16 decoders, then you plug those HDMI outputs into an RF modulator. 

Question:

So if I understand you correctly, you're saying most modern TV sets won't work with an H.265 encoded stream, and if that is the case with our TV's then they won't be able to view these camera outputs on a TV using this product, because it doesn't transcode an H.264 stream into something that a TV would understand. Is that right?

And so to get it to work, I would have to buy something like this: https://thorbroadcast.com/product/4k-hevc-ip-and-usb-hd-video-decoder-ip-8230-2.html
And then take the HDMI output from that, and feed it to something like this: https://thorbroadcast.com/products/hdmi-1
And I would need one decoder and one modulator for each channel? Am I understanding this right?

I'm not an expert, and there may be a perfectly good reason why I couldn't do this... but couldn't I take the H.265 stream, use a computer or server of some kind and transcode it to MPEG or whatever encoding TV's these days need, and then feed that signal into the RF modulator? I'm guessing there is some kind of drawback and would have to be pretty powerful to transcode 8 - 16 live streams simultaneously, but maybe there's something out there, or could use multiple computers.
 
As to QAM vs ATSC, QAM seems nicer and cheaper, but the hope is to put this on the same coax that carries our OTA TV channels from an antenna while we are in port (we work on a ship). So I think I need ATSC, but I may be wrong on this.

OK, that all makes sense. I think someone from Thor just called here, returned the call but the connection isn't great out here at sea...

If the new product with a built in transcoder is really going to be ready in 1-2 months, and you think it'll work reliably, we could definitely wait for that. In fact, if you have a price for it, we could even pre-order it so that we can get it as soon as it's ready.

In case that option doesn't work out, what about something like this? https://thorbroadcast.com/product/iptv-to-32-rf-channel-analog-ntsc-pal-modulator.html
From what I've seen most TV's will detect analog and digital signals and can integrate them without much issue, right?

Good point about the signals changing when going to different ports. Actually, we had that issue at our last port stop in Canada. Not sure what signal they use, but we have a HDMI to RF modulator that outputs pre-recorded video, and it didn't play nice at all with the signal off the antenna, actually ended up disconnecting the antenna completely. Do you sell such an RF filter as well?

Sadly, I had no say in the selection of these cameras. The one who did select them seems to have dropped the ball on this so I'm picking up where he left off and trying to get this portion of the project done. Definitely wish we had selected something more compatible with our needs. Oh well.

Answer:
That is the case. As I noted we're working on a new product that would have a built in Transcoder, so it would be able to do all of this in one step. 
 
But yes, American standard for television is MPEG2. 
You purchased camera's that are H264. So it's just not compatible, the TV won't see the image. 
 
This is a less expensive option: (also I'd stay away from setting those camera's up as H265, there's no benefit in your situation.)
https://thorbroadcast.com/product/compact-ip-decoder-set-top-box.html
https://thorbroadcast.com/product/1-4-or-8-hdmi-digital-rf-encoder-modulator-8230.html/238
 
For the whole package, we would be able to give you a discount of sorts; or you can wait until the new hardware is ready. 
But this is the case that tons of people have when they go to install, most people don't realize codecs and protocols have to match otherwise distribution is dead in the water. 
 
Yes if you're in port, and can pick up ATSC channels, that would make sense. But if you go port to port, or various cities, where the channels change, then you also might have to get an RF filter to ensure those channels never corrupt the incoming ATSC from the camera's. 
 
Basic setup, lets say you have 16 Camera's 
16 STB
16 HDMI modulated inputs
you're already looking at close to 13k without the switches or cabling or anything else. 
 
 
In general this happens a lot, people find a camera they like and install somewhere, could be a warehouse for example; then they realize if they bought the slightly more expensive camera, they'd have an easier time with the headend conversion. 

Question:

How long can this cable be?

What is the device name/number that produces RF1, RF2, RF3,…etc. I do not see it on the website.

Answer:
The device outputs +37dbmv , The TV's are able to decode the signal at 0 dbmv , so we have 37 db to play with.
 
Loss examples.
Coax loss is 3-7db per 100feet , debonding of the frequency
1x4 splitter loss 7.5db
1x8 splitter is 12db
 
If the loss in the system excedes 37db, than you can simply use RF amplifiers.

Question:

How many HD channels can send VIA QAM using the H-IPRF-32QAM ? I was watching the video on the Youtube regarding the product. There is a comment made about 2 full HD Channels and 4 SD channels and that’s confusing be a little bit.

  I think the biggest thing for me a the moment is just figuring out what I will need for taps. Right now there is a 4 port 17 tap in the IDF closet. That tap then feeds the 8 channel splitters that go to each room. I believe each room then either has a tap or a splitter as there are two coax drops in each room. I have yet to track down the j-box up in the ceiling grid those may be living in

Answer:
So the actual answer varies. Reality is that the QAM frequency can carry up to 38mbps of data; so you can use that pipe however you want. 
You can do 1 HD at 19mbps, and 3 SD at 6mbps
or whatever breakdown you like. 
What also matters is if you are sending H264 or MPEG2, naturally H264 is more dense, however most TV's can't see H264, so realistically if you use MPEG2 and want full 1080p60 HD, then we suggest 2 programs at 19mbps; example you can have 20.1 and 20.5 using one frequency but you have two full HD programs on one frequency or channel. 
You can also send 720p at 9mbps each, and technically have 4 programs of HD; however as you know there is a big difference between 720p, 1080i, and 1080p. 
These are all things that play a part in the debate, so there isn't technically a right or wrong answer, it's generally how many programs you want to stuff into the output. 
However the unit itself is designed to output 32 full QAM channels, so in practical terms 64 full HD 1080p programs is very reasonable.

Question:
I have a customer in Chicago that would like to upgrade their current lobby camera system to integrate with their new fiber CATV system with RCN/ Astound. Do you have anything that will insert an analog or IP signal into the RCN / Astound channel line up?
 
 

Answer:
You mention analog and IP for inputs on the modulators; can you be slightly more specific? 
We do have quite a few options. 
How many overall channels are you trying to add? 
Depending on that answer you could use an IP to RF Edge Qam like this H-IPRF-32QAM
But we would also need to know the PID information for RCN, do you have that info available for their boxes?
If they require certain information, you might have to use modulators to do that contribution. 

Question:
We are looking to upgrade our RF modulators onboard the RV Sikuliaq, and we are interested in Thor's product line.
One question- can any of your products take in a network H.264/265/RTSP video feed (from a network CCTV camera) and encode it out as an RF signal?
We have a little of 50 cameras, but we don't need to pipe ALL of them into the TV system.
What are your thoughts on getting a CCTV camera feed to a TV HD channel?

Answer:

So products like that exist, but generally speaking if you want to
output the signal on RF (ATSC or QAM) the video should already be in
MPEG2.
The problem you're going to find quickly is that American Television
sets require MPEG2; if you happen to have TV's that can accept H264
then that's really great and we do have a simple solution.
However if you have MPEG2 TV's, then you're better off using STB's for
IP to HDMI, then using RF modulators to create your RF channels.

How many IP Camera's do you have?

------------------

Well as I mentioned the TV to view those channels needs to be reviewed
of weather they can see H264 or not.
As I noted, chances are they won't unless they are quite new, but even
some new TV's don't have that feature.

Well realistically in cases like this we have equipment that can do IP
to RF. We have units that can output 16 or 32 QAM channels from IP
feeds.
https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/123

But that's only if you already have MPEG2 video.
In this case I would say using a simple IP STB for HDMI output going
to a modulator for RF output is the practical solution.
https://thorbroadcast.com/product/compact-ip-decoder-set-top-box.html
Then we have a number of RF modulators that will output MPEG2 as you need.

Question:

I'm curious to know if Thor has any products that I can use to preserve the functionality of my TiVo Roamio, TiVo Edge, and a number of TiVo Mini (LUXs) after my cable television provider switches from QAM to IPTV

My cable television provider, Cox Communications, is transitioning their television subscription service from an encrypted-QAM-based system with CableCard devices for decryption and channel/frequency mapping on the subscriber equipment (such as TVs or DVR/TiVo devices) to an IPTV-based system with their Contour/Contour-DRV trademarked subscriber technology. I want to continue using my TiVo-based system and avoid leasing Cox's subscriber equipment. I'm seeking third-party solutions, so I'm writing to you.

 

Answer:

If the IP streams are CLEAR UDP Multicast, then you can use the H-IPRF-16/32QAM. However, I doubt that Cox will provide clear unencrypted IP Streams. The H-IPRF-16/32QAM is rated as commercial-grade equipment, 

Another option is to modulate a single channel output from their STB. You can use a 1ch HDMI modulator to encode and modulate HDMI to QAM or ATSC, which you can then use with your TiVo. So, it would work like this:

Cox IP STB -> HDMI -> Petit Modulator -> QAM out to TiVo

Question:
Good day,
We are looking for a solution to connect two Buildings for our Cable Service which is run through an Appear TV Rack Mounted Headend Unit.
 
We wish to Utilize the DataPort of the Appear TV to push Cable TV over IP from
  • Hotel A
  • Connect to IP Receiving Unit 
  • Distribute over RF to 100Rooms in Hotel B
 
Distance between runs will be 500M. We will use a Fiber Optic Cable to Make the Connection
 
What Options do you recommend?

Answer:
So you have IPTV headend, you wish to send it over fiber, then decode from IP to RF, then send the RF to all the hotel rooms?
 
If this is correct then we have some options for you. 
For IP over Fiber I suggest these units:
https://thorbroadcast.com/product/10-100-1000-mbps-fast-and-gigabit-ethernet-over-1-fiber-media-8230.html
The transmit and receive is $398.00 as a kit. 
 
For IP to RF we have these models available:
H-IPRF-32QAM
These can produce up to 32 QAM channels. 
Since you are in Spain, I assume your IPTV transport streams are MPEG4. 
You will be able to put multiple streams on a single RF carrier. 
So if you have 64 IPTV streams, you can put 2 programs on each RF channel in QAM. The same is true if you would like to put 3 TS on one RF channel. 
 
Then if you have coax going through out your hotel, we have amps and splitters for coax if needed:
https://thorbroadcast.com/product/40db-bi-directional-distribution-amplifier-54-1000mhz-coax-catv-qam-atsc-analog-8230.html
 
RF Splitters/combiners - the blue icons above the picture show the assortment we offer
https://thorbroadcast.com/product/coax-multiplexers-splitters-combiners-f-type-input-output-catv-atsc-or-8230.html/257
 
Let me know if this makes sense and if you have any questions. 
 
Also please be aware that if your IPTV headend outputs MPEG4, that your televisions in each room must be available to decode MPEG4 TS as well otherwise this will not work. 
Please check your televisions in reference if they can decode QAM in MPEG2 and MPEG4. 

Question:

We are looking to set up a system for our customer. We are looking to install 4 IP PoE cameras via cat 6 cables to a manual switch to 2 TV's. The customer needs it to be a simple physical switch to switch between cameras (single view). No audio nor recording is needed. What would you suggest for a system? Do you have a specific product for this application?

Answer:
Well I'm assuming you're not talking about an IP switch, but you'll probably need one of those. 
If they are going to 2 televisions then he wants to be able to view them easily, we have an actual controller like this model https://thorbroadcast.com/product/maximuscontrol-professional-grade-video-ptz-controller.html
 
If they're going to a TV then they either need to have HDMI or RF. 
We do have IP to RF converters and gateways, however if your IP camera's are not MPEG2 then those streams need to be encoded first since North American standard for television is MPEG2, and not H264.
We do have a compact 4 channel model if your IP camera's are actually MPEG2 as well H-IPRF-4QAM
https://thorbroadcast.com/product/ip-udp-multicast-to-4ch-catv-rf-qam-atsc-digital-8230.html
 
 
This would allow you to view those Camera's like regular CATV channels on your TV. 
 
 
If the camera's are IP in H264 you can also use the IP STB, you'll need 4, and if the TV's are far away from each other you will need perhaps another set of 4 at the other TV. 
Those STB's will decode your IP to HDMI, then you can use and HDMI switcher to go into the TV. 
We do have an 8x8 switcher for HDMI ports. 
https://thorbroadcast.com/product/8-input-8-output-hdmi-matrix-switcher.html
 
 
Hopefully that helps. 

Question:

I am configuring a H-IPRF-32-QAM product. I have a list of
channels number I need to broadcast as below: 8.1 9.1 10.1 13.1 22.1
23.1 27.1 28.1 29.1 30.1 37.1 63.1 68.1 95.1 95.2 96.1 But I don't
know how to configure the frequency for these channels. Can you please
provide me the frequency list for these channels?

Answer:

We can only do that using VCT (Virtual
Channel Table) numbers, not the physical channels, because they are
too spread out on the RF spectrum.
Please find attached a list of which frequencies are currently
available on your coax.

The device has created blocks of 32 channels, for example, starting
from channel 23 and above. Please set them first.

Attached you will find the QAM J.83b frequency chart and a quick
installation guide for your reference.
. You can configure it in the modulator section.

To proceed, go to the TS property output on each stream, clear the
property, and set the proper Major and Minor channel numbers in the
Channel Tab. Enable VCT on each output (CVCT).

Question:
I am currently trying to retro fit our CATV system at our place, what we basically have is a bunch of receivers and then we use modulators to put it on channels then send it on RG-11 and all that. I was looking at converting it to fiber using some F-RF-TX-2MW and some optical splitters and some Mininode-2RP type thing but then I got interested in the IP conversion stuff you all carry. What I am curious about is I can get into the HDPerformux-24 by going from composite to HDMI and in but getting it back out into the analog world is where I am stuck.
 I saw the h-IPRF-32QAM and what I was hoping was the ability to map video inputs to channels directly and having the option the make the mapping different with different IPRF-32 units but I am curious about the modulator setup, does that get me back at good old analog CATV or is it digital. I am at a prison and most of the TVs in the cells are analog and I need to be back at analog when I split out. 
 
Or other options really. I can go the straight convert to single mode setup and be good with what I want but if I could add inputs and put them on differnt channels (TV) then that would be very handy.

Answer:

Thank you for your inquiry. I will give you a call to discuss this further, as there are several possible approaches. 

The fiber solution is a solid option, and Smile could also be considered.

Transmitter

https://thorbroadcast.com/product/thor-optical-mini-catv-rf-transmitter-45-1000mhz.html

Receiver

https://thorbroadcast.com/product/thor-fiber-optical-mini-ftth-rf-catv-cable-tv-receiver-8230.html

If you prefer an IP-based solution, I would recommend the 24-channel CVBS baseband Video Encoder, which eliminates the need to convert to HDMI:
H-24AV-IP – 24 Analog CVBS Video/Audio H.264 SD Encoder & Streamer.

On the receiving end, we can use the H-IP-32RF, an IP to 32-channel analog RF modulator:
H-IP-32RF – IPTV to 32 RF Channel Analog NTSC/PAL Modulator.

Please refer to the application drawing below:

 

 

Question:
We are exploring adding a client's incoming CATV channels to their IPTV system.
 
They are using Vitec.
 
Will this unit
https://thorbroadcast.com/product/16-rf-tuners-to-iptv-1.html
 
Be able to feed IPTV channels into their Vitec distirbution system?
We want to give them the option for 48 tuners... is that simply 3x of this unit?
 
If I have only 1 main feed coming into the rack room, can you please suggest the right splitter/amplifier combination to distribute to all 48 input ports ?
Do we need only 16 outputs from the splitter, and we can loop out of each port and feed the inputs on the next box in the rack?
 
We do want to have additional outputs beyond these 16 to keep their existing "RF as a backup" Distribution system in place.

Answer:
If the Vitec can accept the MPEG RF signal as in RTP or UDP then yes. 
 
Our high density gateway is a direct translator; meaning we do not touch the RF makeup, it's a direct conversion of coax to IP; so the encoding protocol and data rates are not augmented in any way. 
 
As for the splitting of the RF, we have a full line of splitters/combiners as well as compact amps 
https://thorbroadcast.com/product/coax-multiplexers-splitters-combiners-f-type-input-output-catv-atsc-or-8230.html
 
https://thorbroadcast.com/product/40db-bi-directional-distribution-amplifier-54-1000mhz-coax-catv-qam-atsc-analog-8230.html
(We have rackmount amps as well) 
 
So those RF inputs have a minimum requirement of what the signal dB level needs to be at for the machine to see that RF and decode the program stream. 
In this case, you should get an RF measurement of your RF in the headend (inject an amp here if needed) ; then use a tiny splitter with 4 outputs for the 3 RF to IP gateways and one back into your existing RF system. 
Here each one of those outputs from the 1x4 splitter will go into a 1x16 splitter 
 
Then I would use the spillover / waterfall method to send that input from input one to input sixteen. Those products come with small 4 inch coax jumpers. 
Now you will lose a little rf power on each spill over but not a lot, so you need ample RF input power on the first input to ensure it gets to the last input with signal levels still in tact of the appropriate dB. 
 
I hope that makes sense. I have ample time to discuss today, you can reach me directly at 1800-521-8467 ext 1

Question:

We are looking for a solution where we could receive four RTSP or SRT feeds in real time and have a device that would modulate them into our in-house RF signal. Ideally, we are looking for an all-in-one solution.

These feeds could be coming from several different locations.

-Solution:

As discussed, here is the link for the UDP to 32 CH QAM Modulator (H-IPRF-32QAM), 
H-IPRF-32QAM
https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/123
This unit can generate up to 32 QAM channels from any UDP unicast or multicast stream. 
 
 
Please note that this unit works as a gateway; if your streams are encoded at H.264, the QAM channels will also be H.264. Generally, only newer TVs (approximately 2–3 years old) can decode H.264, as the US standard remains MPEG2. 
Older TVs will not be able to decode these streams without an external QAM to HDMI set-top box, such as this one::
H-STB-QAM/ATSC
https://thorbroadcast.com/product/qam-catv-rf-and-atsc-rf-to-hdmi-decoder-stb-8230.html
 
 
Alternatively, we offer a UDP IP to 64 QAM Gateway with a transcoding option, 
H-HERMES-64
https://thorbroadcast.com/product/ip-to-catv-rf-digital-qam-gateway-with-mpeg-4-h-264-8230.html
 

 

 

Answer:

If the feeds are coming from different locations with different IP addresses, then they would typically need to be decoded separately. Each stream would be handled by its own decoder or IRD.

Customer:
Understood. What product would you recommend for that?
Our goal is to take these RTSP or SRT feeds, bring them into our facility, convert them to QAM, and then distribute them through our internal RF system.

We expect 8–10 streams, but let’s start with 8 streams.

Adam:
Just to confirm — the incoming streams are RTSP or SRT, correct?

Customer:
Yes.

Adam:
In that case, one approach would be:

  1. Decode the IP streams into HDMI or SDI video

  2. Feed those outputs into a QAM modulator

For decoding, you could use the following unit:

Decoder Option

  • DecodePro 4K IP Video Decoder
    https://thorbroadcast.com/product/ip-video-decoder-4-channel-4k-multi-format-hdmi-sdi-vga-8230.html

This is a 4-channel IP video decoder that supports multiple protocols including RTSP, UDP, RTMP, and others, and can output video via HDMI, SDI, VGA, or CVBS.

Each unit can decode four independent streams simultaneously, which makes it suitable for broadcast environments where multiple feeds must be decoded in real time.

You could then connect the outputs to RF modulators such as:

  • Thunder-4 HDMI Modulator - https://thorbroadcast.com/product/hdmi-modulator-qam-rf-coax-output-full-hd-8230.html/238

  • Thunder-8 HDMI Modulator  - https://thorbroadcast.com/product/hdmi-modulator-qam-rf-coax-output-full-hd-8230.html/239

Customer:
Regarding that Decode Pro 4K box — if the source stream is 4K, would I need a 4K modulator as well?

Adam:
Yes. The decoder itself is resolution-transparent:

  • If the incoming stream is 1080p, it outputs 1080p

  • If it is 4K, it can output 4K

However, the RF modulator must also support 4K if you want to modulate a 4K signal.

Customer:
Right. Our Hybrid-8 modulator probably wouldn’t pass 4K then.

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

Adam:
Correct — that model does not support 4K input., this unit will :     H-4K-QUAD-MOD  Thor 4K HDMI CATV RF  Modulator & IPTV / DVB-ASI  Encoder 

https://thorbroadcast.com/product/4k-hdmi-rf-catv-modulator-and-iptv-encoder.html/340

Customer:
Okay, that answers my question. Essentially, you don’t have one single box that takes RTSP or SRT feeds and directly modulates them to RF, correct?

Adam:
Correct — not directly from RTSP or SRT.

However, if the streams were UDP multicast, then we do have an all-in-one solution.

Customer:
What do you have for UDP streams?

Adam:
For UDP multicast streams you could use an IP-to-QAM edge modulator.

Example:

IPTV to RF Modulator

  • H?IPRF?16QAM IPTV to QAM Edge Modulator

  • H?IPRF?32QAM IPTV to QAM Edge Modulator - https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/123

These units accept UDP multicast streams and output them directly to CATV RF channels.

Capabilities

  • Accept multiple UDP streams

  • Output up to 16 or 32 QAM channels

  • Each QAM channel has about 38 Mbps capacity

This means you can place multiple programs on a single QAM carrier.

For example:

If each video stream is ~5 Mbps, then you can place about 6 programs on one RF channel.

So with 16 QAM carriers, you could distribute dozens of TV channels within your internal RF system.

Customer:
That actually sounds like the solution we need.

Adam:
Yes — it works very well when the streams are generated locally as UDP multicast on your network.
