Question 1

I'm in the process of replacing the 480i analog CCTV system on our ship with new 1080 ipcams. Each channel on the modulator is connected to the HDMI output from a raspberry pi. The pi are configured to do one of three things: 1. stream the rtsp feed from an ip camera. This is especially important for deck operations so the bridge can see what is happening. 2.VCN into another computer on the ship and display what that computer is doing (multibeam sonar, USBL, echosounder, Navigation, etc) 3. Run a custom data display showing real-time science data. In addition, we have a 6000m depth rated ROV, which puts out HD SDI video. This goes into an SDI input so people on the ship can watch. The video quality is good, much better than our old analog system. We will be buying a second modulator unit, perhaps just HDMI. A quick question, is there a setting I can massage to get the modulated output on a non-subchannel? e.g. just plain channel 66, not 66-1.

Accepted Answer

In order to have single-digit channel without subchannel, There is a trick you can use it but please test it, not all the TV's support it. In the Major channel number please type 1008, it will be ignored by TV's and on the Minor channel put the channel you require, and just this number will be displayed.

Question 2

Please explain operation Thor H-Hybrid-RF MPEG2 in ISDTb H.264 norm in Chile with local TV set tuners, similar to Brazil and Peru

Accepted 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.

Question 3

We have RG-11 in the ground. How many channels can we carry on this cable at 100 ft.? is it possible to send the ATSC or QAM over 1000feet and 2000 feet?

Accepted 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.

Question 4

I have been asked to update the monitor feeds in the newsroom. I’m not sure where to start but I have an idea what I want to do and I am hoping Thor can help. I will have several HDSDI, QAM, and HDMI sources (20 to 30) I need to feed to video monitors in the newsroom. The number of monitors will be 20-30 but should be scalable. These monitors will likely have QAM and HDMI inputs. If QAM is used, I will need the ability to change the content of the modulated channel rather than changing the channel on the tv. The sources will be in-market competition, national news outlets and custom feeds as needed. Once I see something on one of the monitors I like, I want to be able to bring it up on my computer or laptop and listen to it using something like VLC. There could be as many as 20 people viewing different or the same thing at any given time. I’m looking for equipment recommendations and possibly design ideas that I can further research.

Accepted 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.

Question 5

How to send 100 HD-SDI sources to 300 remote locations, the customer has 300 different locations and has fiber connectivity between them. Please suggest the best and highly reliable way to distribute across these locations.

Accepted 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

Question 6

I had talked to someone on Friday about a quote for our facility.  The gentleman at THOR had recommended the 32 channel IPTV to QAM device.  Would need 7 of them.   Currently, we have 32 DirecTV or COX receivers.  Option A would be to stick with that.  So would need a way to take 32 HDMI signals and get it to an IP Signal to send to the device above. Option B would be to get a DirecTV 3000 receive or Dish Network Receiver that is outputting to MPEG4.   https://www.technicolor.com/distribute/home-experience/play/com3000-solution https://www.dish.com/business/downloads/smartbox-product.pdf

Accepted Answer

Here are the links to those units we discussed.  https://thorbroadcast.com/product/4-hdmi-broadcast-encoder-iptv-streamer-and-asi-out-mpeg2-8230.html   https://thorbroadcast.com/product/iptv-to-16-32-clear-channel-rf-qam-atsc-modulator.html/123   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.  https://thorbroadcast.com/product/8-channel-hdmi-and-sdi-clear-catv-rf-modulator-qam-8230.html Only because we can get you a stellar discount on this model vs the other ones.

Question 7

We are looking for an SDI combiner to RF supporting the Dubai and other Middle East cities modulation standard

Accepted 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

Question 8

My setup is shown in the schematic below. Basically I have multiple HDMI sources going into our surround sound. The surround sound settings also output the audio signal. The HDMI output is split between the TV and a Channelmaster CM-1050 modulator, which combines the signal with our antenna. Although the basic setup works extremely well, the modulator apparently cannot properly handle some of the audio signals. I’m not sure if it is the type of encoding, 5.1 surround, or both. Sometimes there are apparently side channels coming through with no voice, other times nothing.   I would like to confirm that your product can properly handle any audio signal from our players and/or the Chromecast or Firestick after it is output by the surround sound, including Plex personal video server and Netflix.

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

Question 9

I was wondering if the THOR hybrid 8 we just purchase could use 4 RF carriers rather than 8?  The problem we are having is the only 8 consecutive channels we have in this particular system are quite high pushing those channels through the system.  Also, I was wondering if we had to use 8 consecutive channels or we could split them up in some way?

Accepted 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: https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0   You can also try to switch to 64QAM, it has fever losses over the coax because it has less data density

Question 10

I’ve attached a data sheet for the PTZ IP camera. I am looking to have 9-12 of those cameras to be connected to the existing analog CCTV system. 200-270 meter apart. I understand that I will need to have a few hardware modules, in order to achieve my goal. Please suggest what I will need. A sketch would be nice too, so I can visualize the solution. Thank you.

Accepted 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.  https://thorbroadcast.com/product/compact-ip-decoder-set-top-box.html   Then for modulation you can use a few different options, these are the most popular: https://thorbroadcast.com/product/petit-hdmi-rf-modulator-chassis-system-for-1-12-units.html/254 or  https://thorbroadcast.com/product/1-4-or-8-hdmi-digital-rf-encoder-modulator-8230.html/238   You mention your CCTV system is still analog, if you would like to keep it analog then you can use this: https://thorbroadcast.com/product/16-hdmi-to-analog-agile-catv-rf-modulator-ntsc-8230.html   Otherwise the first couple products are digital QAM modulators, the latter can inject HDMI and output NTSC analog.

Question 11

I ran a channel search and I do see the Directv boxes are working as they should.  However, we need the channels to be set on specific channels.  If you could help me get that sorted out that would be great.

Accepted 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

Question 12

1) Using 5 x H-HYBRID-RF-8 +16 ATSC channels from antena, how do i combine them ? Do I need  5  combiners and cascade them? 2) Combiner would receive one RF input, decode 16 signals and combine them with the other 40 HD/SDI?

Accepted 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

Question 13

I am replacing our ZeeVee HDb2312-NA QAM modulators with Thor Hybrid-8 QAM modulators. On the old ZeeVee units, I was able to select the RF channel and then assign 3 sub channels to that RF channel. For example, I could choose RF Ch3 and assign 3-1, 3-2 and 3-3 to be virtual channels in the space of that RF channel. I was using 480i signals. I am trying to figure out how to do that with the Hybrid-8. Within the modulate menu of the Hybrid-8 I have made the following settings: Channel 1, I have set Channel 1 to RF frequency 63 and I have set Major Channel to 3, Minor Channel to 1. Channel 2, I have set Channel 2 to RF frequency 63 and I have set Major Channel to 3, Minor Channel to 2. Channel 3, I have set Channel 3 to RF frequency 63 and I have set Major Channel to 3, Minor Channel to 3. When I do this, I get no output from the modulator for those 3 channels. I must be doing something wrong and hoping that you can point me in the right direction.

Accepted 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.

Question 14

We currently have 3 thor RF modulators and are extremely happy so far with the products.   We would like to bring those channels now to multiple buildings around our city.  I currenty have fibers running to all our buildings.   Can you tell me if this design would work for us.   Currently we have   1 * D-HDCoax-4 unit 2 * H-Hybrid-RF-8     If we would get 1 F-RF-TX with 1 fiber optic splitter (F-PLC-1x16) and F-FP-RX-MN for each building would that bring my RF signal everywhere?

Accepted 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

Question 15

I am checking the information of the Hybrid-8, I kindly ask you to confirm the following doubts:   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 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?     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:

Accepted 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: 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.    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.

Question 16

On the hybrid -8 hdmi unit. How many service at 1080 can I broadcast on each 6 MHz carrier?   If I start at catv frequency for QAM 14  which I presume will be 14-1 can I do a virtual one part number? Eg changing it to display as channel 55 on the television display?

Accepted Answer

The H-HYBRID can only modulate a single program per 6MHz carrier and cannot multiplex multiple programs on a single channel.  As a result, it will occupy 8 physical channels. However, it is not agile—you can spread them out anywhere on the CATV RF spectrum. You can also create any VCT (Virtual Channel Table) numbers for any of them. If you do not have enough space and need to multiplex programs on a single carrier, the only unit with SDI input that supports this is the 4-channel H-4SDI-QAM-IPLL. It allows 2, 3, or 4 transport streams (TS) on a single program. H-4SDI-QAM-IPLL https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0

Question 17

I would like to understand how the product can be integrated with a commercial cable channel lineup (for example, Comcast in a restaurant). The application is to have a video camera with SDI output facing a live music stage, and encode this camera as a tunable channel added to the commercial provider's lineup over coax to multiple TVs.

Accepted Answer

his is actually a straightforward application.  Two things we need to know is are you receiving the Comcast feed as clear QAM, or do you have their Cable TV set top boxes at each TV in order to watch Comcast programming? If it's clear the setup is slightly easier; if you have cable boxes we will need additional information from Comcast and enter that information into our SDI modulators.  Another point of emphasis is locating a vacant RF channel that is not being utilized by Comcast; they should be able to provide you with that information as well.  After that you can use a combiner to bring in your main cable feed and add in the SDI video feed.  https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0 We also have a modulator that includes SDI + HDMI ports, if you have the channels available, you can always add other SDI or HDMI sources and create more custom channels via a PC, digital signage, AppleTV, Roku etc https://thorbroadcast.com/product/8-channel-sdi-and-hdmi-clear-catv-rf-modulator-qam-8230.html

Question 18

I have an arena customer with a very old modulator feeding there in house cable system, it is failing and very much a legacy unit (not sure the brand now)   I need to quote/order the best single channel SDI based unit you have for RF - I Need the absolute lowest possible latency - we do not care about how good the image quality is as long as its HD and arrives as fast as possible to suite TV's around the building. Can you make recommendations from your line?    Long time no talk, hope you guys are doing well... I was at a long time customer of ours yesterday who has some 8 channel Thors that have almost 3 years up time right now... I was impressed

Accepted Answer

I’m glad to hear your customer is still running our 8-channel modulators with almost 3 years of uptime, that’s always good news. For your arena application, the best fit would be our H-1SDI-QAM-IPLL.  This unit is specifically designed for ultra-low latency applications. In Mode 1 latency setting, it achieves about 350ms, which is the lowest possible from our line. Model: H-1SDI-QAM-IPLL  - https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/4 If the project requires multiple channels, we also have the H-HYBRID-8-RF, which supports up to 8 channels. Latency on this model is slightly higher, around 550ms, but still quite fast for multi-channel operation. Model: H-HYBRID-8-RF  - https://thorbroadcast.com/product/8-channel-sdi-and-hdmi-clear-catv-rf-modulator-qam-8230.html Both options will provide reliable HD distribution to all TVs around the building.
