Question and Answers

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

Answer:
No, the 4channel HDMI modulator H-THUNDER-4 has separate Channels for each input but it can be any channel, for example, 2,20,50 99, there is control of each individual channel. Do you need to Multiplex (MUX) all 4 TS programs on one physical frequency (One RF 6Mhz channel)? QAM 236 contains 38Mps data, so you can multiplex 4 programs encoded at 9Mbps each or 8 programs encoded at 4.5Mbps We have different 4 or 12channel unit available https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21 https://thorbroadcast.com/product/catv-rf-modulator-hdmi-multiplexer.html/37

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

Answer:
Yes, I just checked online, the Tivo has ATSC tuner, The modulator sends QAM or ATSC, it is selectable, it will be compatible with a Tivo

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

Answer:
The best way to convert 28 HDMI / SDI to QAM would be using H-HYBRID-RF-8 Modulator, it has 8 independent switchable SDI / HDMI inputs : https://thorbroadcast.com/product/8-channel-hdmi-and-sdi-clear-catv-rf-modulator-qam-8230.html For optical RF coax over a fiber we recommend to use the following devices : Fiber OTx https://thorbroadcast.com/product/32-mw-catv-rf-over-fiber-tx-45-870-mhz.html Fiber Rx Rack https://thorbroadcast.com/product/catv-rf-fiber-receiver-high-rf-power-rack-8230.html F-PLC-1x8 https://thorbroadcast.com/product/1-x-2-to-1-x-128-fiber-optic-couplers.html/226 The main thing I want to point out is that these are all 1310nm; will only work in the CATV band 45-870Mhz for QAM 256 If you are sending L-band (which is satellite TV) in the band 1400-2800Mhz I'm somewhat familiar with the Foxcom stuff, but I just checked the specs on their unit, it uses 1510-1610nm wavelength; so this would not be compatible. If you have different information then what I just read online then please let me know. We have similar, more sophisticated L-band gear https://thorbroadcast.com/product/6-ch-l-band-over-single-fiber-extender-54-3000mhz-cwdm.html And ours is not compatible with the lower band RF CATV gear because they operate in different bands, furthermore, you can not connect a CWDM receiver, like ours or Foxcoms, to a fiber link that is using a single laser, in the different wavelengths. Please give me a call if you'd like to discuss, if you'd like a BOM for the equipment above for a distribution system for point to multipoint let me know.

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

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

Question:

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

Answer:

Is the system QAM?

its Cox cable in Omaha, NE. I just know its HRC

Ok, and are there available channels you can use to insert into?

We need to verify, may need to delete a channel

I see

for now, just need 1 channel

Okay, well any of our Modulators will work, we have 1 Channel units that are compact, some are rack mount; they vary by chipset and various abilities

Will this be some sort of application like digital signage or will you play movies? Live Events etc?

digital signage type

Okay, then you can really go with any model and you'll be fine.

i see. does Thor have a channel delete item?

That's a bit more complex because you need an RF filter

so you'd have to specify which channel, and we make a frequency filter that would block the preceding program on that channel

ok. I know in the old days you needed to stay 2 channels away, but that was analog. is digital different?

I haven't seen a project come through that required such a device in a long while, but yes they still tell you to block out an extra channel on each side.

However I can have our engineers look into that for you to see what they can do

ahh, ok. can you send me some model numbers, non rack mount for now that i can look at?

sure

just the modulator for now

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

looks good. is HRC and QAM same thing?

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

That unit is similar but also includes closed captions

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

ok, nice

so HRC and QAM vary by one thing, and that's starting on channel one or channel two

however, both use 6mhz stepping in frequency modulation

i see

so reasonably speaking, so long as you don't use channel one; then any QAM product should work for you

Because when we discuss modulation, the biggest thing is the Standard, which is cable to ATSC

you have cable

Question:

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

Answer:

but I'm looking to be able to change cable channel from any of the TVs

I know all the tvs will show the same program, but I would like to be able to change the channel from any of them

do you have anything that would do the trick?

we have modulators that can create your own channel from any HDMI source

so if the cable box is set to ESPN and you create it on channel 30

all the TV's in the house on channel 30 will see ESPN

But there is no way to change the channel from the cable box, without using a remote facing at the cable box

In order to do that you would need IR devices

ok, how hard is to install IR devices?

that would be up to the manufacturer spec

we do not offer those kinds of units

We only IR with HDMI over Fiber

what kind of fiber?

it is pre-terminated cable or can I use commercial fiber cable?

You would have to buy the fiber separately

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

LOL I do work with fiber cable, cool

those units are really simple to use, plug and play

but this is an extender only right? I don't see how can I connect multiple TVs

you'd have to send them individually

or you can use a modulator

and then buy separate IR products

ok, I have the cable box HDMI output right connected to what product? and from there to each tv with the extender

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

each TV can receive COAX cable instead of fiber

Question:

With regards to the specification of that model, - RF output on each of the 8 RF channels can be individually set to a frequency and modulation standard (2 on QAM, 3 on ATSC, 4 on ISDBT, etc) Do you mean the modulator supports up to eight RF channel? And each of the 8 RF channels could carry the corresponding SDI input sources? (if the device has 8 SDI input, each of 8 channels will have 8 SDI sources) We need digital modulation. Could you quote for DVB-C, DVB-T, ISDB-T, please provided options for DTMB. SDI input is 2/4/8. Three options. In fact, what the standard configuration for the unit?

Answer:

RF output on each of the 8 RF channels can be individually set to a frequency and modulation standard (2 on QAM, 3 on ATSC, 4 on ISDBT, etc) - YES

Do you mean the modulator supports up to eight RF channel? -YES

And each of the 8 RF channels could carry the corresponding SDI input sources?- YES

We need digital modulation - THIS IS DIGITAL MODULATOR

AS I MENTIONED THIS IS UNIQUE MODULAULATOR IT SUPPORTS ALL WORLD MODULATION STANDARDS, included DTMB

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

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

Prices as follow

1 SDI modulator, H-1SDI-QAM-IPLL

2 SDI modulator H-2SDI-QAM-IPLL

4 SDI modulator H-4SDI-QAM-IPLL

Question:

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

Answer:

So, it is possible but if it is not straight forward, it has to be done in a few steps.

They can set up a streaming channel on Youtube, they can stream to youtube form the cell phone then use IP STB to receive this youtube stream and output as an HDMI, the HDMI would be connected to the modulator.

The video might be delayed about 5 seconds this way.

This is the link to the IP STB:

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

The other way would be to dedicate 1 cell phone and equip it with direct HDMI output then streaming would be not necessary, but maybe a dedicated PC would be more reliable and convenient.
