CATV RF QAM Transmodulator

Descripción

CATV RF to IP Gateway + CATV RF Trans - modulator for QAM ATSC DVBS/S2 DVB-T ISDB-T

16 RF Inputs to IP outputs +16 RF Outputs (RF to IP Gateway + RF to RF transmodulator)
This unit can take existing ATSC channels and convert them to IP streams and QAM RF channels simultaneously (RF input = IP + RF output)
EXAMPLE Model numbers can be (H-16QAM-IP-ATSC ---- H-16DVBS-IP-ATSC)
RF Inputs can be ATSC / QAM / DVBS-S2/ DVB-T/ ISDB-T
RF Outputs can be ATSC / QAM /DVB-T / ISDB-T

This gateway and transmodulator is a unique device that can easily convert existing RF streams, up to 16 frequencies and convert to IP and RF channels. This will allow you to add any RF to existing RF channel bank as well as create IP streams for easy access via LAN. For consideration you can convert ATSC to IP and QAM, or you can convert DVBS2 to IP and QAM, or also use it as a translator so you can take 16 QAM frequencies and convert to IP and 16 QAM (different frequencies, if you like to rearrange your channel lineup). The vast array of options make this an ideal headend piece to quickly and efficiently become more dynamic, add free OTA channels to a QAM headend, or simply create a RF to IP gateway with existing RF programs. This is the exact same unit that is mentioned above with the added benefit of transmodulation, we can essentially mix and match any RF to any RF with a couple exceptions. Please contact your local dealer or Thor directly for more information.

Simply put, it is a 16 RF to 16 RF + IPTV gateway. This is a multi-standard CATV, Air, and Satellite Digital modulation standard transmodulator-converter with IPTV output.

The unit has 16 individual tuner inputs, and depending on the model, it can support the following modulation standards:

ATSC
DVB-C Annex A/B/C QAM 64/256
DVB-S/S2
DVB-T, DVB-T2
ISDB-T

Depending on the model, the output can be ATSC, QAM, DVB-T, or ISDB-T.

The unit can also be used for the same modulation conversions, like QAM to QAM or ATSC to ATSC, for UP or Down channel conversion.

In addition, the device has an IPTV output, so each TS from the inputs can be outputted as a UDP/RTP multicast or unicast for local LAN video distribution over the network.

The device also has 2 independent DVB-ASI inputs, allowing additional TS programs from external encoders to be injected into the modulator as separate channels or subchannels."

Question and Answers

Answer:

Great question, our units are very flexible and designed exactly for this type of application.

You are not limited to passing the full RF stream. Our gateways can work in both ways—you can pass the entire transport stream or select only the specific sub-channels (programs) you want, depending on your bandwidth needs.

You can take a look at:

They can output streams as UDP multicast or unicast, and you can choose between full MPTS or selected programs (SPTS),

making them very efficient for transport over GRE tunnels.

Please review and let me know if this fits your setup.

--------------------

SPTS capability I think is exactly what we need for efficiency. If you use these as SPTS, does that limit each tuner to one channel? or can we send say 2/4 of the subchannels from one tuner? We have 6 desired RF channels but may want to send about 16 channels all together. About half of what's available. Would we need the H-16atsc or would the H-8 work? ------------------------ Each tuner is not limited to one channel. From a single RF carrier, you can select multiple sub-channels, and the unit will generate a separate SPTS stream for each one, only the specific programs you choose. In your case with 6 RF channels and approximately 16 total programs, the H-8ATSC-IP will be more than enough. You can tune those 6 carriers and pull multiple sub-channels from each to reach your 16 streams. There is no need for the 16-tuner unit unless you plan to expand your RF carrier count later.

Answer:
As we discussed, there are several ways to approach your installation and applications. Here are some key points to consider: 1. **RF Input Power:** The RF input power into the 32MW TX should be +15-+30dbmv. 2. **Optical Level:** The optical level by the RX should be about +/-3db. If this is too high, you can use optical attenuators like the 5db SC/APC to SC/APC.
