Description

Universal Modulator that's unique design is the most capable Hybrid on the market.


Up to 8 Channels of HDMI or SDI inputs allow you to select either or in the options menu on the simple and creative GUI. This modulator by Thor has independent input cards for flexibility for Digital Modulation because it eliminates the need for HDMI to SDI or SDI to HDMI converters. Simply select which source you want to use and input the channel frequency creating an automated encoding headend device that can clean up your headend and modulation distribution infrastructure.
 

Each channel can individually be selected as an HDMI or SDI input, it could be switched on the fly using front panel buttons or Thor's dynamic proprietary Web interface. Each of the 8 channels of RF output can be set totally independent as a frequency AND modulation standard. For example, you can input 4 channels as HDMI and set to QAM output and then input 4 channels of SDI and as ATSC output. This flexibility that hasn't been seen before on the market creating a whole new generation of standard for encoder modulation products
 

The New THOR HYBRID Modulator has an NMS port and LCD display with simple D-Pad buttons for control and easy setup on the fly. It includes and supports the majority of modulation standards found in the world; For example: Clear QAM Annex A and Annex B, ATSC-8VSB, DVB-T, and ISDB-T. The Hybrid modulator supports MPEG2 video encoding up to 25Mbps/channel, Audio AC3 or MPEG1 Layer 2, and AAC, Thor's world-famous, low Latency, and VCT -Virtual Channel Numbers for increased for flexibility. Each CATV RF channel can be set individually, so it does not have to be in a linear 8ch block, feel free to spread out your new custom RF channels all over the existing RF spectrum in your modulation lineup.

Question and Answers
Answer:
according to our experience with the countries using ISDB-T, even ones with H.264 as the standard, the TV tuners are universal and can decode H.264 and MPEG2 as well. We send many devices to Brasil and Peru, and customers are very happy with the performance. A similar case is in the US, even if the standard for ATSC and DVB-C Annex B is MPEG2, most new TV's can decode MPEG4(H.264), Transport Stream. Also, our company has a very good return policy in case it would not work for your customers.
Answer:
Higher frequencies have higher insertion loss in the coax. We have 3 different coax cables available for the TV Distribion networks These are Series 59, Series 6, and Series 11 called RG59, RG6, and RG11. Series 59 is the smallest, and Series 11 is the largest. RJ59 has high signal loss over the length, The RG11 is the best and has lees loss of signal loss over length, but is bulky, hard to install, and relatively expensive when compared to Series 6 coaxial cables. Series 6 is the most commonly used size due to the excellent trade-off in price, size, handling and signal loss. The following information is specific to Series 6 coaxial cable. Coaxial cable loss is normally specified in dB loss per 100 feet of cable. Examples for 6 cables loss in ATSC spectrum, 57 MHz -CH2 has only .15 dB/100’ 207MHz Channel -12 has 3.0 dB/100’, 473Mhz -Channel 14 has 4.5 dB/100’, 695Mhz -Channel 50 has 5.6 dB/100’ Please note that RF slitters add the insertion loss as well, for example, 1x2 slitter has 4.5dB loss, the 1x8 slitter has 12dB. RF signal can be amplified or if the coax distance is too high the best choice is to convert CATV RF to an optical signal and send over the fiber using the CATV RF fiber optic transmitter and receiver.

Answer:
At first, glance when I read this I thought our Hybrid- 8 would be an ideal unit because it is universal 8 channel HDMI and SDI. And perhaps in some scenarios, it might still be a beneficial unit to have in the office. When I got to the point where you mentioned that you needed to pull up the stream on VLC, I realized you needed the duality of RF coax and IPTV. then we would like to use separate HDMI and SDI IP encoders / QAM modulators : I think you used them before : https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21 https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0 At this point, I need a more conclusive answer on how SDI feeds and how many HDMI feeds you need, so we can appropriately determine the correct amount of each unit. If you would like to switch the source instead of channels, then you would have to use a combination of HDM Switch + SDI switch connected to the modulators. Signal flow : x HDMI source to x:X HDMI switch to X HDMI modulators H-4ADHD-QAM-IPLL +X SDI sources to X/X SDI Switch to X SDI modulator H-4SDI-QAM-IPLL The modulators would be set to static RF channels, by controlling the HDMI and SDI switch you would inject desired program to the modulator , they would produce static TV QAM channel and IPTV multicast stream at the same time. The only thing is that each time you would switch the sources, it would be about the 5-second gap, our modulators would recognize that this is a different video and it would need to re-encode the video each time. If this is acceptable, then it is a relatively easy task.
Answer:
So, you have 300 end locations, do you need to receive all 100 SDI's in each of the 300 locations? There is a lot of different ways to do it. 1) use multiple 8ch SDI Transmitters over fiber using splitters and run to 300 locations for 100 SDI videos, you would need : 13x 8channel transmitters H-8SDI-3G-TX https://thorbroadcast.com/product/8-ch-sd-hd-3g-sdi-over-single-fiber-cwdm-uncompressed-rack-mountable.html each transmitter would need to be connected to 1x32 optical splitter than you would need to use 13 8channel SDI receivers in each of the 300 locations to convert it back to SDI You would need to have 13 fibers to each location to do that. 2) if you do not need to have SDI's on the RX side, but the ability to view to those videos: You can encode your 100 SDI video and modulate it to Cable TV QAM channels : you can use this 8channel SDI encoder -QAM modulator : H-HYBRYD-RF-8 The output from those 13 modulators you can connect to 1550nm CATV RF transmitter than using EDFA amplified than using optical splitters we can distribute that to each of 300 locations. each end location would have fiber to RF receiver, so each location will get those 100 channels but in the CATV RF TV channels CATV RF fiber transmitter: https://thorbroadcast.com/product/1550nm-rf-over-fiber-tx-45-870-mhz-2-16-mw.html Fiber optic amplifier : https://thorbroadcast.com/product/20-dbm-edfa-optical-amplifier.html Optical slitters : https://thorbroadcast.com/product/1-x-2-to-1-x-128-fiber-optic-couplers.html CATV RF mini receiver https://thorbroadcast.com/product/thor-fiber-optical-mini-ftth-rf-catv-cable-tv-receiver-8230.html
Answer:
Here are the links to those units we discussed. 
 
 
And we also make the IP to RF in a 16 channel too. 
 
I just asked my superior here, we have a massive contract with an installer who hundreds of Planet Fitness and other clubs, they are all doing 12-20 channel headends using our 4 Channel modulators. 
 
I think from the beginning of our conversation when you said 36 I thought that was fairly high. 
The first thing you might consider is lowering that number, I know my local gym here only has about 10 or so, mostly sports and a couple of news channels, CNN and FOX. Plus all the ESPN, CBS and FOX sports. 
 
Might want to consider it. 
 
This is the modulator that would be ideal for you. 
Only because we can get you a stellar discount on this model vs the other ones. 
Answer:

This unit  H-HYBRID-RF-8 is very popular because it is so universal, it has 8 SDI inputs but also 8 HDMI inputs if needed, it supports all the RF CATV modulation standards, so it can be used anywhere in the world

Answer:

Our Modulator can encode to Dolby AC3 2 Audios when your incoming audio format is PMC ( uncompress Audio).
If your source has already AC3 encoded format our modulator passes 2 first audio

Our suggestion is to set all your HDMI devices to PCM audio output and let our modulator handle the AC3 Dolby audio compression, this way will always consistent.

 we do not have complaints about handling the audio, costumes are very happy with the video and audio quality.
 I would suggest getting The modulator and trying it, if it doesn't work as you intended you can send it back because there is no way to predict the contablityt with all the equipment on the market.

I think you could be right that the current channel master does not support certain audio's, you'd have to check those specs. 
Our PETIT unit does have DD pass through and supports all of those kinds of audio's. 
On the webpage there are several youtube videos we have added, some of which shows the demonstration with chromecast and firestick, and the audio goes to the TV without issue. 
Those units have a 30 day return policy, so the best option would be to pick one up and try it out. If you find the same result, then one of the 3rd party splitters or switchers might be the root cause of the issue. 
But if you plug in either of your streaming sticks, to the modulator, to the TV and it works, then you know all those pieces are accepting and passing the Audio. 
Answer:
The H-HYBRYD-RF-8, outputs 8 separate 1 to 1 frequencies, but you can spread them, they do not have to be adjacent.
If you must have 4 frequencies then the only way we can do it is through 2 x 4ch H-4SDI-QAM-IPLL, this unit can mux 1-4 TS's on the single carrier,
 
This is the link:
 
You can also try to switch to 64QAM, it has fever losses over the coax because it has less data density
Answer:
As I noted, it's a two-step process. 
Since you have IP camera's in H264, you will need to convert those camera's to HDMI, then HDMI to a digital Modulator to view on MPEG2 television's which is what we use in North America. 
 
Here is the first part. You will need a dozen of these. 
 
Then for modulation you can use a few different options, these are the most popular:
or 
 
You mention your CCTV system is still analog, if you would like to keep it analog then you can use this:
 
Otherwise the first couple products are digital QAM modulators, the latter can inject HDMI and output NTSC analog. 
Answer:

The easiest way is to change it via web interface,  in this case we
would need to connect PC to the NMS port and access the WEB interface,
you just select channel form the list
The default IP address is 192.168.0.188,  you need to set you ethernet
IP address to the same address 192.168.0.XX ( xx=1 to 254, but not 188
because they can not be the same ip addresses on the network)
this is a link to the document on how to change the IP address  ( it is
for the different modulator , but procedure is the same) .

https://thorbroadcast.com/upload/files/220/nms-ip-connection-instructions.pdf

Answer:

1) You can use 1x8 pasive splitter/ combiner

2)

Your picture is correct, but your sentence  is incorrect "  Combiner would receive one RF input, decode 16 signals and combine them with the other 40 HD/SDI?" 
Nothing is being decoded, just simple RF combining , 1 RF channel has its own  frequency
 
We simply combine 40 CATV RF ATSC channels ( we reproducing those unique channels from the 5  x 8  ATSC Modulators H-HYBRYDE-8)   with the  16  DIFFERENT ATSC channels
 
Please find attached  ATSC frequency chart, I hope it will clear this up
https://thorbroadcast.com/upload/files/220/atsc-off-air-us-television-channels-center-frequency-mhz-chart.pdf
Please check this chart, each SDI input will have its own frequency , those channels need to be different than those 16 from the antena
 
I hope this is clear if not please give us a call 800-521-8467 ext 2
Answer:

This particular modulator doesn't have MUX functionality, each video
needs to be on its own CATV RF channel, but you can assign VCT Virtual
channel to any of them.
So for example, you can set Channels frequency for ch 23,24,25,26...,
and assign VCT as Major channels and minor channels  3.1,3.2,3.3, 3.4

If you must mux multi program on the single physical channel, then you
might consider this unit:
They have a multiplexer build in to it , and can do separate channels
of multi program on single carrier

 H-4ADHD-QAM-IPLL  4 HDMI
https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21

or 4ch SDI :
H-4SDI-QAM-IPLL
https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0

Please check the attached CATV RF channel frequency chart.

Answer:
So once all the modulators are combined into one RF cable output; there's essentially two options for sending this to different points, either point to point or point to multipoint. 
That essentially depends on the layout of your fiber, it must be singlemode only. 
We calculate the optical loss in reverse, so the coupler and distance are the two main driving forces in decreasing output power from the Transmitter. 
 
In your case you can use a 1x16 splitter, you would need a 32mW Transmitter, but also the optical loss in the line and any junction boxes should be checked with an OTDR prior to installing so we know if that would work in your application. 
I hope that makes sense. Also if you will be bringing those signals into buildings that have many televisions, you can consider the rackmount receiver, which is more suitable for commercial settings and has AGC. F-RF-RX-RM
Answer:
To make it even clearer, the RF IN is just a passive RF combiner.
There would be no difference than if you were to use a 2x1 RF combiner. So, you can inject any RF channels coming from the antenna under 2 conditions:
1) the RF channels from the antenna must be different from the RF channels generated by the MODULATOR. Please find attached CATV RF QAM and ATSC modulation frequency/channel chart for your reference
2) Incoming RF power from antenna need to be at the same level as the RF signal generated from the modulator
Please find attached picture from the spectrum analyzer showing combined 16 channels
My answers are below:
  1. The modulator has a RF input. Can I connect a TV antenna (e.g: Shakespeare 3019) in this RF input and having in the RF output signals from: 8HDMI inputs + 1 RF input?
The modulator can take in the RF input antenna signal, however the HDMI ports are only INPUTS; this is a modulator, not a tuner. So you will have to use your own HDMI devices for insertion; this product can not take in RF inputs and output through HDMI. 
 
  1. The block diagram shows the setting of the 8x HDMI inputs (8 channels), but not the setting of the RF input as an independant channel. Can I set the RF input also as an independant channel? In this case.. is it posible to have 9 available channels (8HDMI+1RF) on the users TV?
The point of the RF input is to use it with a correlating signal, like ATSC antenna, or QAM Cable. In this case the modulator creates 8 RF channels based on 8 HDMI devices that you are supplying. 
 
This a summary of the required configuration based in your product (modified with my requirement: Shakespeare antenna added as RF input, channel 9 (RF input) added), please let me if my understanding is correct:
The RF input is a passthrough, so you can connect an Antenna; it will pass through all the channels the antenna is able to receive. Beyond that you can use up to 8 HDMI devices like DVD players, PC, Cable Boxes etc that will be converted from HDMI inputs and create your RF channel on the output. 
 
These modulators are used to create RF channels from various video players. 
In this case I believe you are looking for something to decode the antenna, which is not what this product does. The HDMI ports are INPUT only, the output is only COAX. 
 
Perhaps you can better explain your application, and what you are trying to accomplish; we may be able to help pick a better piece of equipment that can help you more.
