Question and Answers

Question:

If I have (8) DTV boxes connected to all (8) HDMI inputs, does the normal CC produced by the DTV boxes make it to the TVs, and is it displayable? I understand that I can turn on CC on the DTV box but that would display on every TV tuned to that channel. Ideally, I would like to use the TVs built-in CC ability to allow people at each TV to turn on/off CC - independent of whichever DTV box/channel they are displaying. Can you let me know what I can expect? If CC is not transmitted to the TV, how can I take advantage of the CC RCA input on the back with the DTV boxes? Thanks for your help in advance..

I was looking at the commercial DTV boxes (H24) and did not see a CC output. Is there a current model that supports this that I should try to get?

Answer:

You need to make sure the modulator is hooked up with HDMI and the CVBS as well. HDMI doesn't carry Line 21 data, that data actually has the CC. Without taking the CVBS from the DTV box and into the HDCOAX-8 you're only passing audio video to the modulator and not the CC. Once you hook up the CVBS ports from the STB to the modulator it will work right away.

The HDMI video doesn't carry separate CC, if you turn the CC on the STB, it will become part of the Video image which we will encode it, it will be always on the RF,

You can connect HDMI from the STB as a source of the Video and Audio and separate CVBS baseband video output for the same STB as a source of CC -closed captioning, our modulator will detect and read the CC information for the analog video CVBS signal encoded on line 21.

The modulator will generate a separate CC608 strem together with the MPEG video and audio strem, from this analog CVBS signal.

Now, you will be able to turn ON/OFF CC on this specific channel on the TV using the remote control

Question:

I need to set up a RF network, i need an advice and a quote,
I need to set up a 10 channel tv network and send the RF (coaxial cable 75ohm) signal to 28 TVs inside a 10 store building.
The channels will come from a DSTV (digital TV decoder with satellite dish outside) the DSTV decoders use a HDMI cable to deliver video and audio.
I need the Coaxial cable to deliver 10 different channels to the 28 TVs giving the opportunity to each individual TV user to select and change the TV channel at any giving moment in his room.
The distances are long between the TV's the longest one is almost 390meters from the network room where I want to install the modulator.
How can you help me?

2----------------------------

Do you already have a coax network in place? I have no network its a new building i need a new instalation.

What modulation standard do you use in your country? MPEG-4 AVC/H.264 COFDM (Coded Orthogonal Frequency Division Multiplex) QPSK, 16-QAM, 64-QAM and 256QAM. 1K to 32K

Please send me the topology drawing if you can - I dont have one unfortunately but i can try to build someting close to it.

I think my optios are between the H-8HDMI-QAM-IPLL and H-12HDMI-QAM-IPLL

Answer:

Thank you for contacting us, we have a gate solution for RF over coax distribution.

Please check those 8and 4 ch HDMI modulators you could use to produce 10 channels form DSTV decoders via HDMI

Coax distribution is very easy and straightforward.

I would recommend combining 4ch and 8ch H-HDCAOX-8, because of the price. The 12ch HDMI is more expensive because it also has IPTV output.

The topology would be handy, I could tell you what splitters and taps you could use and where, but I will explain briefly how it works.

An RF meter would be needed during the installation.

Basically, we will output 35dBmv RF power from the modulators , than you will conect it to a 1x2 (4.5db loss) or 1x4 (7.5db loss) or 1x8 (13db loss splitter) , each splitter has different RF power insertion loss

There is also loss in the coax, depending on the frequency used average 4db per 100 feet ( 30m) The TV's can see the RF even at 0 dbm, so you have 35dv RF budget.

After the splitter you could use RF amplifiers if needed, in the other locations you could also use splitters or cascading TAP's , Tap has an INPUT, Drop or Drops, and Output for the next cascading TAP.

The easiest way to do it is to calculate the losses and plan it out, if not then connect the modulators and check the levels in the end locations and determine if Amps are needed or not.

Question:

Good morning, well what I need is for you to advise me. I have a hotel and I want to modulate TV channels. I do not know if it is the right word or what I need to do. the rest of the rooms and I found the equipment that you distribute. Not if it is possible to do what I think. My question is how I change the channel in the rooms to see different channels is it possible to do it.
 How could it be possible to obtain the equipment in Ecuador and what would be the equipment that you would recommend.
I thank you for your help

Buenos días bueno lo q necesito es que me asesore tengo un hotel y quiero modular canales de tv no se si es la palabra correcta o lo que necesito hacer tengo contratada una empresa que me brinda el servicio de televisión pagada de la cual quiero ver canales en el resto de habitaciones y me encontré con el equipo que usted distribuye no si es posible hacer lo q pienso mi pregunta es como lo cambio de canal en las habitaciones para ver diferentes canales es posible realizarlo.

Como podría en caso q se pueda realizar obtener el equipo en ecuador y cual sería el equipo q me recomendaría.

Le agradezco por u ayuda

Answer:

This is very easy, let's say you will get 2 units 8ch HDMI modulator, you can connect 16 different Video sources like DVD players, Computers, Satellite Set to boxes,

We take those 16 HDMI videos and modulate them on the different TV channels, now any TV connected to the Coax network can scan and receive those channels,

Since this will be clear, unencrypted CATV RF QAM channels, you will just use the TV's remote control to flip those channels 1-16, I'm assuming you currently have Cable or Antena COAX network in place

Please let me know if this is clear.

if you take 2 or more, you use a simple CATV RF passive combiner to combined them together.

Gracias por la explicación.
Esto es muy fácil, digamos que obtendrá 2 unidades de modulador HDMI de 8 canales, puede conectar 16 fuentes de video diferentes como reproductores de DVD, computadoras, satélite a cajas,
Tomamos esos 16 videos HDMI y los modulamos en los diferentes canales de TV, ahora cualquier TV conectado a la red Coaxial puede escanear y recibir esos canales,
Dado que esto será claro, canales CATV RF QAM sin cifrar, solo usará el control remoto del televisor para cambiar esos canales 1-16, supongo que actualmente tiene una red de Cable o Antena COAX en su lugar
Por favor, avíseme si esto está claro.Podemos ofrecerle un precio de exportación con descuento de $ 3200 + envío para el modulador HDMI H-HDCAOX-8 de 8 canales, si toma 2 o más, usa un simple combinador pasivo CATV RF para combinarlos juntos .

Question:

I need more information What is the RF Power output?

Can This modulator transmit on Chanel in HD example 33.1 or 33.2? Have 8 HD channels

Answer:

The output power is +35dbmv,

This modulator outputs 8 individual 6Mhz channels, but you can do Virtual numbers like 33.1, 33.2, but they will be modulated on the 2 different frequencies.

If you need to mux and modulated 2-3 or more programs on a single carrier then we have different unit H-4ADHD-QAM-IPL, 4ch HDM Imodulator ( with Mux function) , for 8 channels you would need to cha 2H-4ADHD-QAM-IPLL, and combined ( cascade ) them together,

https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21

Question:

Just following up with an extra question, we have existing equipment between our ZeeVee, Contemporary research, Thor, and a Cox UCrypt box all generating RF and stabbing into a combiner before being distributed through the building. Is there anything we will need to make sure of with that or, will the H-12HDMI-QAM-IPLL just plug and play into our RF system after configuring it to the appropriate open channels/frequencies?

Answer:

Once you have our unit configured to the RF channels you want to utilize, then into the combiner as you noted and you're done, just make sure you're not overlapping any channels.

There's nothing else you need to do.

You might have to go to the TV's and do a QAM scan again so the TV's see the new channels, some television models immediately see them, some require scanning again.

Also we can preconfigure the 12 HDMI unit for you, so when you get it, all you have to do is connect all the cables.

Another thing you should since you have several manufacturers equipment running, the dB level RF output from the various units might be an issue if they are all quite different.

So double check that as well, our units puts out around, ball park 35dB, so if another company's unit is outputting significantly higher RF levels, like 60dB, that could be an issue.

Make sure all the levels are in a similar area.

Question:

Can H-HDCOAX-8 carry two-channel per QAM (example 11-1 & 11-2) , It seems that the batch that we received allows only one channel per QAM

Answer:

The H-HDCOAX-8 outputs 8 separate 1 to 1
frequencies, but you can spread them, they do not have to be adjacent.
you can also create VCT like 11-1, 11-2 but on separate RF carries.
If you must have 2 on 1 the only way we can do it is through
H-4ADHD-QAM-IPLL, this unit can mux 1-4 TS's on the single carrier,
but the price is much higher

Question:

What can you offer me to distribute HD television in the rooms of our hotel? we receive TV channels via HD decoders. the 14 signals from the decoders pass through an analog modulator which sends the modulated signal via a coaxial cable to the rooms. The furthest room is almost 1000m away. we have system of amplifiers all along the way.

--Question 2

is there a way to use an optical fible to send the signal to the most remote locations? We already have an optical fible network for our computer network.

Answer:

Seems like you already have a modulation system in place; this is the best option for cable distribution.

However if you have HD decoders, and an analog modulator then you are paying for HD but serving your rooms with SD because of the analog mod.

My suggestion would be to upgrade to HD modulation and provide HD channels to all your rooms.

You can add HD mods one at a time, like this

https://thorbroadcast.com/product/hdmi-rf-modulator-chassis-system-1-12-units.html/254

Or you can use a high density modulator like this model which has 8 HDMI inputs

H-Thunder-8

https://thorbroadcast.com/product/hdmi-modulator-digiatal-rf-coax-output-full-hd-8230.html/239

This is the most logical way to upgrade your system.
