Description

H-8DVB-T-IP 8 Channel DVB-T/T2 Terrestrial Antenna RF to IPTV Gateway

The Thor Broadcast H-8DVB-T-IP is a professional 8 tuner terrestrial RF to IPTV gateway designed to receive DVB-T and DVB-T2 digital antenna broadcasts and convert the available TV programs into IP transport streams for distribution over a LAN network. This model is intended for countries using the European-style digital terrestrial television system, including many regions in Europe, Africa, the Middle East, Asia, and parts of Oceania.

DVB-T and DVB-T2 are off-air antenna broadcast standards, similar in concept to ATSC in North America, but used in many other parts of the world. The signal is received from a terrestrial TV antenna, not from satellite and not from cable QAM. The H-8DVB-T-IP receives those antenna RF channels, demodulates the digital broadcast multiplexes, and outputs the selected programs as IPTV streams.

8 DVB-T/T2 Antenna Frequencies to IPTV

The H-8DVB-T-IP includes 8 independent terrestrial RF tuners. Each tuner can be set to a different DVB-T or DVB-T2 broadcast frequency. Since one DVB-T/T2 RF channel can carry multiple TV services, radio services, and sub-programs, the gateway can extract the available services from each tuned multiplex and make them available as IP streams.

This allows local terrestrial broadcast channels to be distributed to IPTV set-top boxes, smart TV decoders, computers, monitoring systems, digital signage players, and other IP video devices. Instead of installing individual DVB-T/T2 receivers at every display location, the antenna reception can be centralized in one rackmount headend device and then shared across the network.

How the H-8DVB-T-IP Works

A rooftop antenna, MATV system, or terrestrial RF distribution system receives local DVB-T/T2 broadcasts. The RF coax feed is connected to the tuner inputs on the H-8DVB-T-IP. The unit locks to the selected digital terrestrial frequencies, reads the transport streams inside each multiplex, and allows the operator to select which programs should be sent to the IP output.

The selected TV services are output over Ethernet using IPTV transport stream protocols such as UDP, RTP, or RTSP. The system can be configured for multicast distribution when many users need to watch the same channels, or unicast streaming for direct device-to-device delivery.

DVB-T and DVB-T2 Regions

DVB-T and DVB-T2 are widely used outside North America. In general, DVB-T/T2 is common across Europe and is also used in many African countries. DVB-T2 is the newer and more efficient version, often used for HD services and improved spectrum efficiency. Public references list countries using DVB-T or DVB-T2 in Europe, Africa, and other regions, with many African countries adopting DVB-T2 for digital terrestrial television. Always confirm the local broadcast standard before ordering, because some countries use other systems such as ATSC, ISDB-T, or DTMB.

Examples of Countries Using DVB-T or DVB-T2

Common DVB-T/T2 regions include the United Kingdom, Ireland, France, Germany, Spain, Portugal, Italy, Poland, Czech Republic, Slovakia, Hungary, Austria, Switzerland, Netherlands, Belgium, Denmark, Sweden, Norway, Finland, Greece, Romania, Bulgaria, Croatia, Slovenia, Serbia, Bosnia and Herzegovina, Albania, Estonia, Latvia, Lithuania, Ukraine, and many other European countries.

In Africa, DVB-T2 has been adopted in many countries, including Kenya, Tanzania, Uganda, Ethiopia, Ghana, Malawi, Mozambique, Namibia, Zambia, Zimbabwe, Seychelles, Mauritius, Lesotho, Togo, Mali, Madagascar, Algeria, and the Democratic Republic of the Congo. Some countries may use different digital TV standards or mixed systems, so local RF planning should always be checked before system design.

DVB-T/T2 Frequency Range

DVB-T and DVB-T2 terrestrial TV broadcasts are typically transmitted in VHF Band III and UHF television bands, depending on the country and local frequency plan.

VHF Band III: commonly around 174 MHz to 230 MHz, with 7 MHz channel spacing in many regions
UHF Band IV/V: commonly around 470 MHz to 694 MHz or higher depending on the country, usually with 8 MHz channel spacing
Typical European DVB-T/T2 channels: VHF E5 to E12 and UHF E21 to E48/E69 depending on local spectrum allocation
Common UHF center frequencies: 474 MHz, 482 MHz, 490 MHz, 498 MHz, 506 MHz, 514 MHz, and continuing in 8 MHz steps

In many countries, the upper UHF TV band above 694 MHz or 790 MHz has been reassigned to mobile LTE/5G services. For this reason, the exact usable frequency range depends on the local broadcast authority and the current national frequency plan.

Advantages of DVB-T/T2 to IP Conversion

Centralizes off-air terrestrial TV reception in one headend location
Converts antenna RF broadcasts into IPTV streams for LAN distribution
Reduces the need for separate DVB-T/T2 tuners at each TV location
Allows selected programs from each multiplex to be streamed individually
Supports multicast IPTV delivery for efficient one-to-many distribution
Works well for hotels, campuses, hospitals, government buildings, telecom rooms, and private IPTV systems
Can help combine local terrestrial channels with an existing IPTV channel lineup
Maintains the original incoming broadcast quality because the unit works as a gateway, not a video re-encoder

Important Difference Between DVB-T/T2, ATSC, QAM, and DVB-S/S2

The H-8DVB-T-IP is for DVB-T/T2 terrestrial antenna input. It is not the same as the H-8ATSC-IP used for 8VSB off-air antenna signals in North America. It is also different from the H-8QAM-IP, which is for clear cable QAM RF input, and the H-8DVBS-IP, which is for satellite dish / LNB input. Choosing the correct model depends on the RF signal type used in the customer’s country or system.

Question and Answers

Question:
We currently have one unit that does what we are looking for, but we are currently experiencing some issues and would also like to have another vendor option so we are not locked into just this one piece of equipment. So, just a quick recap of what we discussed regarding what we're looking for in this encoder. We need it to be capable of receiving 8 separate ATSC and/or QAM signals. Each input should be capable of outputting all of the programs or cherry-picking individual programs and outputting simultaneously to a QAM modulator and IP address, which can support unicast or multicast. Each output should have a dedicated QAM channel and IP address and port #. The QAM modulator should output 8 RF carriers and provide a minimum of 25dBmV, but preferably 40dBmV. EAS is also a big one for us. We would like the EAS to be able to override the current programs with the EAS message when the EAS alert is detected. Our EAS is a multicast stream with a dedicated port #, and when this dedicated multicast IP and port # is detected, it automatically overrides all programs with the EAS message for the duration of the EAS message. We have some equipment that is capable of just detecting the EAS stream and overriding the programs that way, and other equipment requires a trigger in the form of a dry contact along with the EAS IP stream. I imagine that is software related.

Answer:

This is the perfect solution for you: 8 x ATSC or Satellite Antenna Tuners to IPTV & ASI Output H-8QAM-IP H-8ATSC-IP. Or this one: 4 x Satellite or ATSC IRD Decoder to IP, ASI H-IRD-V4-ATSC H-IRD-V4-QAM. This is a link: https://thorbroadcast.com/product/4-x-satellite-or-atsc-ird-decoder-to-ip-and-8230.html

Question:
I need a device that will intake the OTA signal and convert it to QAM output. Need 16 or 32 QAM. Also, I need information on the 16 QAM to IP

Answer:
We have 16 RF tuners to IP and 16 tuners to IP + RF Out They can be configured and ordered with different modulation type tuners. One group converts RF to IP only The second RF to IP and RF out (it works as an IP gateway and RF to RF transmodulator) Please find my answers below: I need a device that will intake the OTA signal and convert it to QAM output. Need 16 or 32 QAM. The best unit to do that is H-16ATSC-IP-16QAM: 16 ATSC to 16 QAM and IP out https://thorbroadcast.com/product/16-rf-tuners-to-iptv-ts-qam-output.html/116 Also, I need information on the 16 QAM to IP and product for OTA signal to QAM H-16QAM-IP - 16 QAM to IP Gateway OTA signal to QAM H-16ATSC-IP-16QAM: 16 ATSC to 16 QAM and IP out

Question:
I want a device that takes analogue and digital (QAM 32,256) through cable and gives output in the form of SPTS IP

Answer:
Yes, the ideal product for QAM to IP. The unit has 16 independent tuners; it can be tuned to any QAM frequency. Any program muxed on this frequency will be available as a UDP multicast SPTS stream. https://thorbroadcast.com/product/16-rf-tuners-to-iptv-ts-qam-output.html/117 Please check and let me know if that would work for you. However, unfortunately, we do not make any gateways that convert Analog NTSC RF to IP. For the analog channels, those would need to be decoded to CVBS video/audio or to HDMI using Analog STBs and connected to the video encoders like this one: H-4ADHD-QAM-IP-LL 4ch CVBS or HDMI inputs https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html/21 4-24ch HDMI encoders: https://thorbroadcast.com/product/4-8-16-24-hdmi-iptv-streaming-8230.html/216

Question:
I'm interested in using an RF to IP gateway and have a few questions about its setup: If I connect a single coaxial cable from a high-powered antenna (which picks up all available over-the-air ATSC channels) to the RF input of the gateway, will the device be able to detect multiple OTA channels, such as Channel 2 and its subchannels, as well as Channels 4, 5, 11, and their subchannels? Can it break these channels into separate IP streams? I've seen a setup where an Ethernet line connects to a switch, and from the switch, multiple feeds go to tuners or TVs. In this case, does the switch need to be an unmanaged switch, or does it need to support specific protocols for the network to function correctly?

Answer:
The ATSC model will pick up all the minor channels behind the major channel. The OTA inputs can be set to any non-adjacent carrier and converted to IP UDP unicast, multicast streams. You can use an unmanaged switch; but that is more relevant to how you plan on using the device. Generally speaking, all modern switches come equipped with all the necessary means to ensure interoperability. You can plug in multiple Gateways into a switch as well. Specifically, the options with this model are UDP, RTP and RTSP. Your network should be able to handle that, but also make sure you have the bandwidth available (depending on how many OTA channels you decide to convert to IP).

Question:
I'm looking at the H-8ATSC-IP product. We want to receive off air from broadcast stations and cherry pick selected subchannels for transport to a transmitter site via a private IP radio link which is capable of about 100 Mbps. I'm not sure what to do at the receive end but we need to feed ATSC 1.0 into an exciter. This exciter has ASI and TSoIP inputs. We would like to put as many programs as possible through the system. H.264 encoding?

Answer:

Thanks for reaching out about the H-8ATSC-IP.

This is simply a gateway, you would not be able to change any of the data rates of video protocols. However you can cherry pick your channels from 8 Major's of your choosing. We do have IP to RF Edge QAM devices, but if your Exciter only accepts ASI and TSoIP, then I would think you can use the UDP or RTP streams from the 8ATSC-IP model. However all of this would still remain in MPEG2, the original CATV channels you pull from the OTA. If you want those channel in H264 you would need to decode then encode those particular channels. There isn't an efficient or easy way to transcode at a high density, I would think that you would want to do that prior to hitting your IP radio link so you can subsequently capture more sub-channels prior to the IP conversion. There is a rather common solution, albeit not elegant; utilizing standard STB's to capture the RF ATSC programs, output via HDMI and into high density encoders which output H264. https://thorbroadcast.com/product/qam-catv-rf-and-atsc-rf-to-hdmi-decoder-stb-8230.html https://thorbroadcast.com/product/4-8-16-24-hdmi-iptv-streaming-8230.html/216
