Question and Answers

Question:
We were reanalyzing our current installation. We currently have an analog modulation while the options proposed are digital. We are planning to change from analog to digital but we need to make sure all needed equipment for the migration will be available. We have to distribute the signal in two separate building and we wanted to use the existing cabling if possible. The second building is receiving the signal by an RG 11 cable and we have 1 Signal Amplifier is installed in each building see the attached file for more details. We have the following Question? Can the signal from that modulator H-4ADHD-QAM-IPLL work with the attached line amplifier? If no How can we send the signal to an extension building located at 200m from the main modulator? Thank you for providing us clear explanation that will lead us to fine decision!

Answer:
We are happy to hear that your project is moving forward, Using our HD HDMI modulator your video clarity will increase tremendously compared to the current analog modulated video. The Digital QAM is also an analog modulated signal, it just carries digital information, so you treat it the same way as the analog NTSC/PAL modulated RF. All of your infrastructures stays the same. You can even have both Analog and Digital on the same coax, we can generate any different frequency then you currently using for your analog and using simple 2x1 combiner you can have both at the same time. It will work fine over your 200m coax cable. If needed for the additional extension we have fiber optic RF to Fiber / Fiber to coax extender https://thorbroadcast.com/product/thor-optical-mini-catv-rf-transmitter-45-1000mhz.html

Question:
What is CC input means?

Answer:
CC input means Closed captioning, the unit reads CC from Line 21 from CVBS baseband video input and encodes it into the stream. So for example, if you have DVD player with the HDMI and CVBS baseband video output, you can connect it to our unit bot of them and modulator will encode HD video from HDMI source and closed captioning form CVBS, the reason behind it is that HDMI doesn't carry CC as a separate signal data stream It is not necessary to use it is just an additional function, because of some costumes requires for the TV's where need to be muted.

Question:
One requirement of the system is to have minimum latency on the channels as these are used interactively on pan-tilt-zoom (PTZ) cameras, control of the DVRs and control of the satellite receiver channels. A long latency will cause the operator to "overshoot" the point they want when controlling the PTZ and similar problems with the entertainment DVRs and satellite receivers. We totally recognize there will be more delay with the digital system over the analog one but need to minimize the latency as much as possible. Iset Mode 1 but have been playing with the manual setting and hopefully found a setting that is acceptable. The manual is not too descriptive (page 34 of the PDF file) of the DTS Delay values and GOP values in the modes and normal. So I am not guessing on the values and have a starting point, if you could fill in the below table ASAP it would help in my installation this weekend, Thor Broadcast H-4ADHD ATSC Encoding Delay Settings Input Resolution Encoding Type Low Delay Mode DTS Delay Setting GOP Bframe Setting GOP P frame Setting Average Delay (ms) HDMI 1080i MPEG-2 Mode 1, HDMI 1080i MPEG-2 Mode 2, HDMI 1080i MPEG-2 Normal, HDMI 1080i H.264 Mode 1, HDMI 1080i H.264 Mode 2, HDMI 1080i H.264 Normal ,

Answer:
I suggest setting mode2 @ 1080i to test. This is a better-balanced configuration. The main parameter affect encoding delay is the DTS setting. The minimum DTS value is 50, it could be set lower but it requires higher STB/TV decoding capacity. In mode2, the DTS value is about 150. Other parameters like GOP, B frames have an insignificant effect on the delay

Question:
We are in the process of migrating from analog RF cable tv to digital solution. The system is used for monitoring conductor etc, and the latency is a big issue. We are currently modulating 12 channels to ca 350 screens in wardrobes etc and the system is also used for the stage because the analog coax solution is close to zero latency. That is also the reason why it has been kept alive for so long. However, it’s not easy to find TVs with no/low latency anymore – even for analog RF. We are looking at SDI/SVSI/SDVoE for the stage area, but we won't look at DVB-C/T for the wardrobes where the latency is a little less critical. I see on your website that your modulators have a low latency option with 70 – 110ms and that is probably low enough for the wardrobes. Your modulators are only specified with DVB-T – will that work on physical coax? If not; do you have a DVB-C option/version?

Answer:
All units you see on our website are available in all RF modulation standards; some units like the Thunder-4 and the Hybrid-8 have all standards built-in, so it's just a setting in the GUI, you can switch to DVB-C or DVB-T in just a few clicks. https://thorbroadcast.com/product/8-channel-hdmi-and-sdi-clear-catv-rf-modulator-qam-8230.html https://thorbroadcast.com/product/1-4-8-hdmi-digital-rf-encoder-modulator-full-hd-up-8230.html/238 Other units like the 4ADHD need to be ordered with specific modulation standard, they must be loaded with firmware to ensure proper standards are operational. Please let me know which model you were interested in and I will let you know if that model has expandable options or needs to be set up in advance with the proper firmware.

Question:
I guess the H-4ADHD-QAM-IP-LL (low latency?) would be the best choice for us then - giving us flexibility in the transition period. How many can be daisy-chained? And do you have units for analog RF? Or should we insert the H-4ADHD-QAM-IP-LL after the old analog system? Also; we have a text system for translation in all the seats in the venue and this system has a mirrored output on normal HDMI - can this be converted to Closed Caption? Alternatively, I will ask the vendor Marconi if the RS233 feed can be converted to the CC standard...

Answer:
You can daisy chain as many units as you like, each unit would generate different channels, for example the first would generate ch 2,3,4,5 the second 6,7,8,9, We have 135 channels available, so in theory, we can combine 33 modulators, modulating on the different frequencies ( different channels). QAM channels are actually very similar to analog channels, they also occupy 6mhz band, so you can just replace analog or combine them together, so on the same coax you can have analog and digital modulating channels, when there are modulated on different frequencies, the frequencies for digital QAM and analog NTSC /PAL are the same Those ADHD models will output CC as well, it needs to be input via baseband video in the back of the unit alongside the HDMI input; the unit will encode the CC information onto the HDMI video and will output it on the RF channel. The CC inputs read recognize and read the Closed Captioning Line 21, so it would need to be provided in this format into the unit, and encode it as a CC608. this way the CC can be turned on /off on the TV level. You could also inject ( glue) the CC into actual video than it will be encoded the same time as a Video, but then it will be permanently displayed on Tv's all the time. In other words our unit needs to receive CC in form of the analog CVBS Video Line 21 in order to be encoded to CC 608

Question:
We have a couple of your HDMI HD QAM boxes that are loaded dual HDMI and dual SDI. we have used them in the United States for many years but last year I took them to China and couldn't get them to work with their TV's. This year our show is in Stockholm Sweden and I thought I would reach out to see if there is compatibility or if I would need different boxes. The download of the manual isn't working FYI. I get pages with squares on it. The in-house guy at the venue says "We use 8MHz channel bandwidth, modulation 256QAM max. 40Mbit/sec. /8MHz." What I can't tell is if the boxes I have to do that exactly. any help would be great. thank you

Answer:
So essentially they have different standards than us. In America we use QAM 256 Annex B; in Europe, they use QAM 256 Annex A; In China, they use an RF standard called DTMB; other parts of the world use DVB-T or ISDB-T; So Television sets have built-in Tuners that can see the RF standard that is generally used in that country; so you can't just take a modulator from one country that uses a different standard and expect it to work. In the states we commonly use QAM and ATSC for over the air; both of which are 6Mhz bandwidth; DVBT I know is 8Mhz step; so again they are not interchangeable. We have 8ch HDMI SDI Digital modulator with all world RF modulation standards, this is the link to H-HYBRYD-RF-8 https://thorbroadcast.com/product/8-channel-hdmi-and-sdi-clear-catv-rf-modulator-qam-8230.html

Question:
I have 2 types of TVs(LG's and Samsung) that I am trying to feed 1080P60 over QAM. However, when selecting H264 setting under the Input Video Format I found that Samsung TV's do not see the video signal from our encoder when H264 is selected. I am struggling to find a setting that works with both TV's. Do you have preset information for each brand of TV's capabilities? Also under the Auto-Config button, there is a list of video resolutions that can be chosen from but there is not 1080P resolution that can be chosen. Will this be available in a future update?

Answer:
Every TV manufacturer has different settings and options. We suggest being consistent when purchasing televisions. We use MPEG2 in America as our primary encoding protocol, so the vast majority of TV's will only be able to see MPEG2; there are a few brands that do have H264 available, however that is very, very rare. So if you are using this type of encoder in an office, or bar, chances are that you will have to use MPEG2 and NOT H264, because all tv's can see MPEG2. I suggest you use that protocol or purchase tv's that can see H264. Most of our Modulators, including H-4ADHD-QAM-IPLL, can encoder video as MPEG2 and H.264, please log in to the unit, in Input in encoding section, please select MPEG2

Question:

I intend to use this modulator for MDU Video insertion purposes.Will your this modulator work with the Comcast Set To Box, QAM channel 134 and display channel 1851,1852,1853,1854,1855,1855,1856,1857,18581859, 1860 or 1901. How to set it up. Can I MUX ( multiplex) 4 of those videos on the single RF frequency Channel carrier and have them as a sub-channels

Answer:

Our 4 ch H-4ADHD-QAM-IPLL worked on the Comcast system as an inserted channel.
We have simple GUI instructions on how to set it up, we can percent it everything before the shipping, so it would be just plugged and play.
We have also other similar modulators for 1,2,8 and 12channels.

Question:

I'm working on improving my bases TV system. I'd like to be able to take a few laptops and display some PowerPoint slides. I'm looking at the H-4HDMI-QAM IPLL but don't know which one to go with. The ATSC, or QAM, or DVBt version. Can someone help me choose the correct one? We use a lot of the Blonder Tongue AMCM-860D's for our other channels. We are located within Phoenix, AZ.

- It comes up as cable.

Answer:

That is an excellent choice, and for the RF output option you'd most likely go with QAM.

DVBT is a foreign standard, since you mention you're in AZ, that won't work for you.

ATSC is standard 8VSB Off Air Antenna; so modulators can be used in this standard if you have an antenna RF infrastructure and then would like to add some custom cable channels of your own. So QAM is your bet; my assumption is that is what your Blonder Tongue units are. Oddly enough I researched that model and it is actually NTSC; which is the old analog variety of RF. So I'm not sure if you can purchase those in QAM or ATSC or they are only NTSC. The easy answer to find out is if you go to a TV on premise and do a channel scan to find channels on the coax plugged in the back, do you do Cable Scan or Off air Scan?

- Okay so then they are QAM units. So the H-4ADHD-QAM-IPLL is the unit you'd want to select.

Question:

We are looking to upgrade our current Radiant Communication MDU Encoder QRF-5000-1-m. We would like to upgrade to have an HDMI input instead of composite. WE use this over Comcast cable to our community. I would to see if you have an upgrade available for us to work with our service

Answer:

Yes, we have the perfect solution HD Video insertion solution for the Cable TV MDU application

Our encoders have various inputs needed to channel insertion.

Please let me know if your service requires Comcast cable STB's or they are using CLEAR QAM ( the coax cable is connected directly to the TV)

Question:

How you can use IP TV UDP output from the H-4ADHD-QAM-IPLL CATV RF modulator / IP encoder?

Answer:

An IP TV UDP output from an IP encoder can be used in several ways. Some common examples include:

Distributing the IP TV signal over a local area network (LAN) to multiple devices or TVs that are connected to the network.
Streaming the IP TV signal over the internet to remote devices or TVs using a streaming service such as YouTube or Twitch.
Connecting the IP TV signal to a digital signage system to display the content on multiple screens or TVs in a commercial or public setting.
Transmitting the IP TV signal over the air using a digital TV antenna to reach TVs in a specific geographic area.

Overall, the specific use for the IP TV UDP output from an IP encoder will depend on the user's specific needs and requirements.

Question:

I am not sufficiently versed in IPTV so would appreciate your recommendation.

At a new facility we'll feed out local live production along with incoming signals from 12-14 other tracks. The origin of the latter is Dish Network receivers with HDMI out. Of course, we can convert our HD SDI output to HDMI.

The live local needs to be the lowest possible latency, for obvious reasons. It's less important that the income tracks be low latency because there's no live action to compare to.

Do you have a product that will accommodate both? or do I need a separate encoder for the live?

If we get into this, I'll need to please ask you to educate me on multicast!

Many thanks for your advice and great products!

Answer:

Please review the following options:

1) H-4ADHD-QAM-IPLL: 4-channel HDMI QAM modulator/IP Encoder with QAM
latency around 300ms and IP latency of approximately 800ms.

2) H-4SDI-QAM-IPLL: 4-channel SDI QAM modulator/IP Encoder with QAM
latency around 300ms and IP latency of approximately 800ms.

https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html/0

3) If latency is not a concern, I suggest the H-THUNDER-8, an
8-channel QAM modulator with latency of about 500ms.

Question:

I am reaching out about your 4 HDMI to ATSC modulators and IPTV streaming encoder. I see it has RF in. I was reaching out to make sure that if there was an antenna that went into that "RF in" that it could be distributed through the IPTV system? And if so, would it take one of the 4 channels that the HDMI ports are using? Thank you for the assistance!

And then would it be possible to have the rf gateway and iptv encoder go to the same ethernet switch to go out together on the same output? So both inputs go into one switch, and then one singular output?

Answer:

es, that model has an RF input and an RF output.

To your point it sounds like you'd want to combine the 4 HDMI inputs from various HDMI sources and add them to the existing channels from an Antenna.

You can input the RF from the Antenna into the RF input on the Modulator. You can also use an External 2x1 Comiber, it's the same thing essentially.

However you have to make sure the channels you assign the 4 HDMI inputs are not overlapping channels from the Antenna.

In order to properly assimilate the 2 RF streams together, they must be on vacant frequencies. Putting those HDMI sources on existing channels will not work.

The easiest way to do that is with an RF scanner, or just check online in your city which frequencies are vacant.

As for inputting RF antenna and expecting the model to output the antenna channels in IP is something it will not do. The only IPTV stream outputs would be from the 4 HDMI sources you are feeding the system.

So if you feed it 4 BluRay Players, then you can have 4 RTP/UDP/RTSP streams in multicast or unicast.

If you are looking to convert RF channels from an Antenna and converting them to IP channels or streams, then we have a different product for that called a Gateway.

https://thorbroadcast.com/product/16-rf-tuners-to-iptv-1.html/116

This is our most dense RF Gateway, which can take up to 16 ATSC frequencies, Major and Minor channels, and convert them to IP streams.

We also have this available in an 8 RF channel input model.

Yes, you can connect both the Gateway and the Encoder to the switch; it needs to be a smart switch with the IGMP protocol enabled.

The IGMP works in a way that it keeps the streams in the switch's memory and passes the individual streams to the specific port where the stream was requested by any IP receiver or decoder.

This is more detailed explanation how the IGMP works:

IGMP (Internet Group Management Protocol) is a communication protocol used to manage the membership of Internet Protocol (IP) multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish multicast group memberships. It plays a crucial role in enabling efficient network resource usage, especially for services like multicast video streaming. Here’s a simplified explanation of how IGMP works with multicast video streams and how it helps preserve bandwidth while allowing video access to anyone on the LAN network:

Multicast Video Streaming

Multicast Streaming: Unlike unicast streaming, where a separate copy of the video stream is sent to each requester, multicast streaming sends only one copy of the video stream to the network, regardless of the number of requesters. This method significantly reduces bandwidth usage.
Group Membership: Devices that wish to receive a specific multicast video stream will join a multicast group. The multicast group has a specific IP address that represents all devices interested in receiving the video stream associated with that group.

How IGMP Works

Joining a Group: When a device on the LAN wants to start receiving a multicast stream, it sends an IGMP message indicating its desire to join a specific multicast group.
Multicast Router: The local router receives the IGMP join request. The router then knows that it should forward traffic for that multicast group to the network segment where the request originated.
Leaving a Group: If the device no longer wishes to receive the multicast stream, it sends an IGMP leave message. If there are no more interested receivers on the LAN, the router stops forwarding the multicast stream to that network segment.
Periodic Queries: Multicast routers periodically send IGMP queries to discover if there are still devices interested in the multicast group. If no devices respond with a desire to remain in the group, the router assumes there are no interested receivers and stops forwarding the stream to that segment.

Preserving Bandwidth

IGMP efficiently manages network resources by ensuring that multicast traffic is only sent to network segments with interested receivers. This way, the bandwidth is not wasted on sending video streams to parts of the network where no device is interested in them.

Access by Anyone on the LAN

Open Access: Any device on the LAN can join a multicast group to start receiving the associated video stream, making multicast video streams accessible to anyone on the network who wishes to receive them.
Dynamic Membership: Devices can join or leave a multicast group at any time, allowing for flexible and dynamic access to video streams based on interest.

In summary, IGMP facilitates efficient distribution of multicast video streams by managing group memberships, preserving bandwidth by directing streams only to interested receivers, and enabling open access to video content for any device on the LAN network that chooses to join a specific multicast group.

Question:

Do you have digital modulator that can accommodate 4 HDMI input and 1 RF output. I need the 4 sources to be modulated and output on one UHF frequency.Can the 4 channels output adequately at 720? The customer is looking to use ATSC

Answer:

Yes we do have a 4 Channel modulator that can do that.

Just keep in mind you will be limited by the bandwidth on the RF channel with 4 programs on it.

Model # H-4ADHD can be ordered in ATSC or QAM

On QAM 256 you have 38mbps of data available. You can still be in 1080 @ 9.5mbps of data rate on each HDMI input and the quality is still excellent.

It's much more difficult on ATSC which only has about 19Mbps, so each input would be under 4.5mbps.

An ATSC (8VSB) channel can only contain a 19.2Mbps bandwidth. With four programs on one channel, we would need to encode each at about 4.5Mbps. Due to US standards, we are forced to encode in the MPEG2 standard and the 4.5Mbps is a bit low for HD 720p.

If that is acceptable for your customer, we can definitely do it using this device. In some cases, customers encode static video like newscasts at 3Mbps to create more room to allocate 7Mbps for sports channels with a lot of movement. Yould can put 2 programs on 2 different RF channels as well.

So you can have channels 8.1 and 8.4, and then 9.2 and 9.5. This would be the best option for ATSC.
