Description

RF to IP Gateway

Broadcast FULL HD IPTV content from 16 TV frequencies that can be ATSC / DVBS-S2 - or QAM(A&B) / DVBT / DVBT2 / ISDBT
EXAMPLE Model numbers can be ( H-16QAM-IP ---- H-16ATSC-IP ---- 16-8DVBS-IP )
The 16 Input Tuners choices are: All
The IP Output format is UDP multicast or multicast
FTA tuner inputs can be set to any non-adjacent carrier and converted to IP UDP unicast, multicast streams.
After setting the frequency the unit scans for Video/Audio programs and once discovered they can be converted individually to IP streams or re-modulated on different frequencies(channels) or a different modulation standard.

It supports up to 512 IP inputs and one IP (MPTS) output through GE1 and TS input for re-mux through 2 ASI ports. This is the next generation of Gateways of which will create a seamless conversion of RF programs to IP TS that are easily managed via a secure NMS system developed by Thor to help distribute all of your programs via IP and ASI. Convert 16 CATV in either DVBS2, QAM, or ATSC to IP or Transmodulate one format of RF to another form of RF. This family of products equipped with 16RF tuners is model dependent for QAM/ ATSC/ DVBS2 and works as RF to IP Gateway and can output Multicast or Unicast also can act as an RF Translator.

Because we use RF Tuners with specific modulation formats, these models are all independent of each other and must be ordered correctly because they are hardware based; we offer them in standards used across the globe so you can use your specific modulation standard for your country (please check model selection, reach out to your local dealer or call Thor directly). Essentially there are 3 hardware sets we manufacture, one specifically for ATSC, one for DVBS-S2, and the third is for QAM (the QAM model has built in modulation standards for QAM Annex A and Annex B, DVB-T, DVB-T2, and ISDB-T; this is selectable through the NMS GUI)

Question and Answers

Answer:
Are your channels clear or scrambled and need CAM cards? This unit would convert 16 clear channels to IP, you would need 2 pcs. https://thorbroadcast.com/product/8-x-atsc-or-satelliete-antenna-tuners-to-iptv-8230.html 2 x 16 CH H-16DVBS2-IP 16 x Satellite S2 Tuners to IPTV & ASI Output The unit can discover all TS's programs and broadcast each SPTS for each TS. What do you need to do with those streams on the other end? Do you want to leave it as an IP and use IP STB? Or convert this IP to RF QAM or DVB-T. If so this would be the best unit to do it: IP to 16/32 CH RF Gateway https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html I totally understand, but this unit has 16 RF inputs, it converts 16 individual channels to IP. so with those 2 pcs you can move 32 channels You are absolutely right, it would be easier to use fiber optic converters RF to RF. So you don't have dark fiber? But if you have fiber with, anything on there, maybe ethernet or L-band? Whatever doesn't matter, then we can make a pass through mux for you. We can do a custom product for you and multiplex anything on the single fiber. To explain it better, if you would have something already occupied by RFor Ethernet or ASI /SDI. We can build a unit with that and have that signal and in addition RF as well? Does that make sense? Please take a look at this CWDM multiplexer for example : https://thorbroadcast.com/product/chassis-multiplexing-system-for-sdi-ethernet-gigabit-ethernet-rs-data-8230.html
Answer:
Yes we have a direct converter that will take RF programs and convert them to IP streams; however that device is not an encoder but rather a Gateway, so the programs will maintain their MPEG2 protocol. If you would like to convert to H264 then you would have to use a tuner or STB, for each stream with an HDMI output; then those HDMI outputs would go into a broadcast encoder which will then convert each HDMI input to an IP stream in H264. This is our very popular 8 Channel HDMI to IP Encoder https://thorbroadcast.com/product/8-hdmi-broadcast-encoder-iptv-streamer-and-asi-out-h-264-8230.html Otherwise, if MPEG2 would work out then you can use this device as the gateway for RF to IP https://thorbroadcast.com/product/16-rf-tuners-to-iptv-ts-qam-output.html/116 Considering we use MPEG2 in North America to view streams; if the client to elects to convert to H264; they would still need to use a decoder to grab those IP streams and convert to something you can view on.
Answer:
This unit is a gateway, so it demodulates and converts the signal type from RF to IP, however, it will not change the protocol standard. 
So if your current RF television system is MPEG2 then the IPTV will be MPEG2. 
If you are in a country that uses DVB-T MPEG2, H.264, or H.264, then your IP will be in came MPEG 2 H.264, H265
It does not support Encryption, so anther words, the RF input needs to be clear and IP output will be clear.
This is the only Tuner Gateway we have in this density.
What is your application, please describe in detail, our engineers will happy to review its ad advise the best solution. 800-521-8467 Ext 2
Answer:

Yes, absolutely, the device can scan and discover all subchnnelTS insight the physical ATSC carrier, any subchannel transport strem can be encapsulated to its on IP strem of your choice. you can also re-map the PID's as well. This is the perfect solution for ATSC to ATSC3 transformation for lighthouse tv programming channel sharing receiver and IP gateway

Answer:
 
How many of each signal are you trying to encode? Where is the Youtube source coming from?
I would think 8 RF channels, 1 or 2 HDMI, and YouTube would be via web.
and what protocol on multicast did you require?
youtube is from the web, but in order to integrate, you need to receive it, then encode it again
I watched YouTube video for the 16 rf tuner to IPTV to qam. Not to knowledgeable in this area, a network engineer by trade. Multicast would be UDP. Perhaps a Firestick or Roku device to get YouTube.
Okay so this would be a multi device setup.
We can use RF to IP Gateways' for your 8 ATSC channels
Then an encoder for XX amount of HDMI inputs you need.
Those IP outputs from those devices would all go to one switch and from there you'd have all your multicast streams.
Which part numbers should I look at?
H-8ATSC-IP
this is the gateway for RF to IP
2 HDMI input encoder for HDMI to IP
Excellent thank you
Answer:

Do you want to use it on LAN or WAN?
I'm assuming WAN, in this case, UDP multicast would not work.

What you can do is stream your Video to Youtube using RTMP
protocol, and give all your friends and family, private links

You can use this encoder for this purpose :
https://thorbroadcast.com/product/4-channel-hdmi-cvbs-network-encoder-streamer-udp-rtp-unicast-multicast-8230.html

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

This is the solution :
 
H-16ATSC-IP-RF, 16ch ATSC tuners to IP, each tuner can be set to the different channel, and output all it will output multicast streams, then you need to have a Video server which will accept UDP multicast, convert it to HLS and serve the customers,
We do not make video servers, you could use WOWZA for example
The reason is that Public internet doesn't support UDP multicast streams, you can use them easily on the LAN, nut, not on the WAN, this is why you need a Video server with HLS, RTSP or RTP outputs
Answer:

Because these cameras are H264, we need to convert and encode those transport streams to Mpeg2 and then modulate onto ATSC for RF to your television. 

 
As I noted, there are a couple of ways to do this. 
I think this is the simplest solution. 
Input the IP from the camera, take HDMI output and then use HDMI modulators. 
Here is a link to our modulators. 
 
Since you have between 6-12 camera streams, you can use individual compact units or higher density models 
--------------------------
Answer 2
This IP to RF gateway is just a converter, it does not encode, so your IP Streams will still be H264, the television will not recognize those channels. 
You need to encode those H264 streams to MPEG2, otherwise, it will not work. 
Answer:
So you're correct the 16QAM-IP unit will work; if your customer needs IP STB's we have 2 options, managed and unmanaged.
 
So if your customer has Samsung TV's that support IP input, it could work in theory; its rare though someone has TV's that will work with Clear IP streams. 
He will have to find an app that will ingest those streams, the issue is Samsung only allows certain apps on their TV sets, so he will have to navigate that himself once he uses the RF decoder to IP. 
 
Please give me a call if you have more details about the project, 1800-521-8467 ext 1 
Maybe there is another solution, otherwise he will have to use IP STB at every TV, the IP streams will need to get scripted then loaded onto each STB, then IP input and HDMI output to the Television. 
For the reasons above is why most customers use RF modulators, it's cleaner, easier and simpler to implement. 
Answer:
We do indeed. If you're talking about CATV QAM or ATSC, we have modulation specific equipment for either case. 
The minimum number we do is 8 Channels. 
 
I assume your gigabit network is your own LAN? Or is it via Public Internet?
Answer:

1)

Yes we do, you can find it here:
H-16QAM-IP
So yes you can do that many channels in one chassis if you would like to do that. 
2)
So each input is an independent tuner, you can use your One input , and then cascade the rest. The unit comes with 16 short coax jumpers for that reason. 
Output can be either UDP or RTP.  Otherwise this is a RF to IP Gateway so there won't be any other changes versus what you input into the unit. 
So if you inject a feed that is MPEG2 and AC3, that is what will come out on the IP side. 
Each RF input per channel, let's channel 5, will include all minor channels as well. so if you have 5.1 and 5.5 and 5.7 all on that carrier, then they will all be converted to IP. 
3)
That's correct, because if you want to do all those things, then you need to encode those signals; again this unit is a gateway not an encoder. 
So there are no options internally that would allow you to do those things as a Gateway. This is strictly for RF to IP conversion  - whatever goes In QAM would go out in IP intacct
To shrink the signal is the much more complex and expensive process
One way is to use  MPEG Transcoders , the second way is to decode each video to baseband Video and use separate encoders to re-encode the stream according to your needs.
Both methods are comlex expensive and require a lot of equipment.
 
Are you intending to utilize gateway IP output for the LAN IP distribution or WAN (Public internet) ?
The IP output from the QAM to IP gateway is UDP multicast, if you intend to use those streams in your LAN, than you do not need shrink it, LAN has enough bandwidth and also IGMP support to prevent  network clogging.
3)
That might work, because we can outputs unicast RTSP streams from it, but again there will be no data rate reduction the data rate and encoded format will be exactly like on the QAM, so it depends on your SD-WAN bandwitch
Answer:

I understand your point. How many channels do you need to modulate?

We do have 8-channel HDMI modulators available which generate valid channels and static images even without an HDMI source connected.

Therefore, you could use simple 8 ATSC to HDMI decoders with an 8-channel modulator.

This way, even if you lose the signal for some reason, the TVs will retain the channel information.

 
Will it work for you ?
 
This is the link to 8ch HDMI modulator
H-THUNDER-8
 
 
This is the link to ATSC to HDMI decoder STB
H-STB-QAM-ATSC
 
 
Thi is the simple application drawing
 
 
Answer:

For the 20 channels, you would need 20 ATSC STBs and 3 H-Thunder-8 modulators combined together. Each modulator would generate unique 8 channels, which you can then merge together.

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

So, to make this clear, our ATSC to QAM gateway works exactly like BT. This is why I proposed a different solution.

If you use ATSC decoders combined with the 8ch HDMI modulator, you will not have this issue.

The 8ch HDMI modulator has a constant output whether HDMI is connected or not (the TS is constantly generated), so TVs will never lose channel information regardless of whether they receive HDMI video or not.

Please let me know if this is clear

Answer:

1) Usually, satellite dishes don't send high-frequency C-Band signals over coaxial cable. Instead, installed LNBs downconvert C-band frequencies to a lower frequency band.

The satellite dish reflects the signal onto the LNB, which is mounted on the arm of the dish.

The LNB amplifies the signal received from the satellite and downconverts it to a lower frequency, enabling it to be transmitted through a coaxial cable to the receiver.

The satellite LNB works as a downconverter by converting the high-frequency satellite signal received by the dish into a lower frequency signal known as the L-band.

The L-band frequency range typically used for satellite communication is between 950 MHz and 2150 MHz.

The satellite LNB converts the received satellite signal, which may be in the Ku-band (10.7 GHz - 12.75 GHz) or C-band (3.7 GHz - 4.2 GHz), into a lower frequency signal in the L-band range.

Once converted to the L-band, the following devices can be used :



F-Lband-TxRx  1 L-band over fiber TX/RX Kit

L-BAND over Fiber Tx+Rx Basic 1 Ch Kit

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

2) In this case, it is not so straightforward; it is impossible to
digitize the L-band spectrum and send it over IP.
However, in some cases, we can tune into specific DVBS/S2 channels and
convert TS (MPEG transport stream) videos to IP.
The video channels need to be free-to-air, clear, and not encrypted.
 Please check this product, the 16ch DVBS/S2 to IP gateway.
The unit has 16 individual satellite tuners, and each tuner can be set
to a different satellite DVBS/S2 (frequency) channel.
Any videos from this channel can be output as UDP multicast streams.
These streams can be sent over the LAN Ethernet connection.

H-16DVBS2-IP

 

 

Answer:

1) The highest density unit we make for QAM to IP is this model: H-16QAM-IP

2) Each of the 16 ATSC channels has an average of 3-4 subchannels, resulting in a total of 48-64 subchannels, other words, each TS (Transport Stream) has its own UDP SPTS  multicast stream

3)

The same concept,
Each tuner can be tuned to a specific QAM frequency.
 
If each QAM frequency has only one Transport Stream (TS), then our unit will output one IP program per QAM channel.
 
However, usually the TS's are multiplexed onto QAM channels, meaning that each QAM channel, which has a 38 Mbps space, typically carries multiple TS's, each of which is usually encoded at 4-8 Mbps.
You can verify this on DirecTV equipment by looking for listings under the same frequency, such as channel # 2 (57 MHz) with subchannels 2.1, 2.2, 2.3, and so on
 
There is no limit on the number of outputs of the equipment, as the number of outputs is equal to the number of TS input streams.
Answer:
I checked that Bolivia uses RF standard modulation ISDB-T; In this case if you have a TV service or antenna in your facility to provide those TV channels to your location; you can use an RF to IP gateway to convert all of the ISDBT channels to IP streams. 
We have a product that can convert those RF channels easily: H-8ISDBT-IP
 
Do you know how many channels you have available through your service provider or antenna?
The maximum amount this device can intake is 8; so if you have 32 channels then you will need 4 of these devices. 
You will need to have a switch connected to your LAN with IGMP. 
Furthermore in order to decode those IPTV streams at your TV you'll require an IP Set Top Box at each location to convert ethernet to HDMI; HDMI cable connects to the TV. 
We have two options for these decoders:
Answer:

Thank you for your inquiry.

As you correctly pointed out, the H-8ATSC-IP or H-16ATSC-IP gateway will output all TS's UDP multicasts from the 8 ATSC carriers.

But the unit works as a gateway and is completely transparent; whatever encoded signal is carried on the RF will be outputted on the IP. We can change PIDs or other PSID information, the encoded video and audio original format remains the same. In other words, the video encoded format and resolution will be exactly the same as the original format of the ATSC channels.

The only way we could achieve a resolution change would be by decoding all your videos to HDMI format first and then re-encoding all of them using an HDMI encoder.

We can use a simple ATSC STB, such as the H-STB-QAM-ATSC, to decode it to HDMI.

Please let me know if any of these solutions would possibly work for your application.

Please don't hesitate to give me a call if you have any questions.

Answer:
We do have both DVBS/S2 and ATSC to IP decoder Gateway systems available. 
You can get those with either 8 or 16 RF into them with IP output. 
 
For HDMI sources we have a plethora of encoder options; depending on how many HDMI inputs you need to convert to IP this one is popular:
It can do from 4 to 24 HDMI inputs. 
We also have another unit called the Spartan that would be a good fit potentially
 
If you need IP input and HDMI output Set Top Boxes for televisions, we have those available as well. 
 
So if you can give us more information on how you'd like to set up this LAN video system, we can give you some part numbers and estimates. 
This is a fairly straightforward application so long as neither of the RF streams you want to decode are encrypted. 
--
There lies the problem in itself. Generally smart TV's know this, well the companies that make them. So you'd have to essentially jail break them and get your own app on board. 
But realistically get one of the TV's and look up the specs and see what's available. Maybe one does have a VLC player or something. Not sure how that would all work out since you need to type in the syntax. 
The other thing you need to check is if the TV's are just MPEG2, or H264 capable; as the ATSC streams are MPEG2, and the Encoder streams would be H264. We also have encoders that can do MPEG2 IP outputs, but they are much pricier per channel. 
 
This is the largest of issues when we see places like stadiums with huge corridors and spaced out TV's elect to switch from RF QAM, to let's say an IPTV system. 
 
So there are several things at play here, and you need to have your ducks in a row to ensure it will all be working in harmony. 
 
Answer:

The Advanced Television Systems Committee (ATSC) standards dictate how TV signals are broadcast and received. Two of the most notable standards are ATSC 1.0 and ATSC 3.0, and they differ in various technical aspects, including their physical layer characteristics.

ATSC 1.0 (also just "ATSC"):

  1. Modulation: ATSC 1.0 uses 8-VSB (8-level Vestigial Side Band) modulation. This is essentially a digital version of amplitude modulation and was chosen mainly for its compatibility with the existing NTSC system and its simplicity.

  2. Transmission: It operates in the 6 MHz VHF and UHF TV channels.

  3. Payload: The effective data rate for ATSC 1.0 is about 19.39 Mbps per 6 MHz channel.

  4. Performance: In practice, 8-VSB is not very robust against multipath interference. This means that in certain areas (like urban canyons) or with particular types of interference (like moving vehicles), ATSC 1.0 can suffer from reception issues.

ATSC 3.0:

  1. Modulation: ATSC 3.0 uses OFDM (Orthogonal Frequency Division Multiplexing), which is a type of multi-carrier modulation. This makes it much more robust against multipath interference than 8-VSB. It can also accommodate various modulation constellations including QPSK, 16QAM, 64QAM, and 256QAM, depending on the desired trade-off between data rate and signal robustness.

  2. Transmission: Like ATSC 1.0, it operates in the 6 MHz VHF and UHF TV channels. But with its adaptive capabilities, it can adjust based on reception conditions.

  3. Payload: Because of its adaptive nature, the effective data rate for ATSC 3.0 can vary. However, it can theoretically achieve higher data rates than ATSC 1.0 in optimal conditions.

  4. Performance: Being based on OFDM and having adaptive capabilities, ATSC 3.0 is designed to be more robust against various interference sources, providing better indoor reception and mobile reception. It also supports MIMO (Multiple Input, Multiple Output) technology, further enhancing its reception capabilities.

  5. Additional Features: ATSC 3.0 is not just an upgrade in terms of physical layer characteristics. It comes with other enhancements like support for 4K UHD, high dynamic range (HDR), better audio quality with Dolby AC-4, and even interactive features and hybrid content delivery in combination with broadband.

In summary, while ATSC 1.0 was a significant step forward from the analog NTSC system, ATSC 3.0 is a more advanced and flexible system designed to meet the needs of modern broadcasting, combining over-the-air transmission with broadband for a comprehensive and interactive viewer experience.

OFDM (Orthogonal Frequency Division Multiplexing) is a modulation scheme that has found its way into various modern communication standards due to its robustness against multipath interference and its efficient use of the spectrum. Here are several notable standards and systems that utilize OFDM:

  1. Wi-Fi Standards:

    • IEEE 802.11a: An early Wi-Fi standard that brought OFDM to wireless local area networks.
    • IEEE 802.11g: This Wi-Fi standard merged the best of 802.11a and 802.11b, using OFDM for higher data rates.
    • IEEE 802.11n (Wi-Fi 4): Introduced MIMO (Multiple Input, Multiple Output) in combination with OFDM.
    • IEEE 802.11ac (Wi-Fi 5): Uses multi-user MIMO (MU-MIMO) with OFDM.
    • IEEE 802.11ax (Wi-Fi 6): While it primarily utilizes OFDMA (a variant of OFDM), which allows for better spectrum efficiency by letting multiple clients share a channel.

  2. Digital Subscriber Lines:

    • ADSL (Asymmetric Digital Subscriber Line): Used for broadband data transmission over telephone lines.
    • VDSL (Very-high-bit-rate Digital Subscriber Line): A faster variant of DSL, also based on OFDM.

  3. Mobile Communication Standards:

    • LTE (Long Term Evolution): Uses OFDM for downlink (from the tower to the device) and SC-FDMA (Single Carrier Frequency Division Multiple Access), a variant of OFDM, for the uplink.
    • 5G NR (New Radio): The latest mobile communication standard also utilizes OFDM with various enhancements for different scenarios and use cases.

  4. Digital Terrestrial Television:

    • DVB-T (Digital Video Broadcasting - Terrestrial): The standard used for broadcasting digital TV in many parts of the world.
    • DVB-T2: An enhanced version of DVB-T, offering better spectrum efficiency and more robust transmission.

  5. Digital Radio:

    • DAB (Digital Audio Broadcasting): A standard for broadcasting digital radio, used mainly in Europe.
    • HD Radio: A standard used for AM and FM digital radio broadcasting in the U.S., which uses a form of OFDM.

  6. Power Line Communication:

    • HomePlug AV and AV2: Standards for data transmission over electrical power lines within a home, utilizing OFDM to handle the noise and interference present on power lines.

 

 

Answer:
The ATSC to IP Gateway takes the data as presented in ATSC and converts to IP; it does not encode or change the TS, including cross converting channels from MPEG2 to H264.
 
Again, this model is a Gateway, not an encoder, so it takes the streams exactly as they are, data rate, resolution, audio etc and strictly converts that information to UDP or RTP.

There is 2 ways to do it:
 
1) Decode any video to HDMI or SDI and re-encode it using H.264 encoder
like this one H-HDPerformux-8 
 
We also have the ATSC STB's,decoders, RF in HDMI out
 
2) We do have 8 port ATSC transcoder but it can only support 8SD or 4HD streams
 
 
Answer:
Yes, you can use one coax line to pick up multiple ATSC channels and break them out into individual IP streams.
Each of the 8 or 16 tuners is independent and can be set to its own unique OTA channel frequency.
H-16ATSC-IP or   H-8ATSC-IP
 
For example, if you connect your high-powered antenna to RF In 1, the unit will scan channel 2 - 57 MHz and discover all the TS's muxed on that particular carrier.
Each TS can then be output as its own UDP multicast or unicast IP address. 
So, a fully populated 16-channel H-16ATSC-IP unit can output all the streams from all 16 unique physical channels.
 
The unit has RF inputs and loop-out outputs for cascading purposes. 
We recommend using a managed switch with IGMP protocol so that the multicast streams can be managed efficiently. 
This will prevent network congestion by sending only the streams that have been requested.
