Description

Multi-input CATV QAM / ATSC / DVB-S2 / ISDB-T trans Modulator with IP Out

Inputs are :

4 RF Tuners : DVB-S/S2 or QAM or DVB-T or ATSC
2 ASI Inputs

Outputs are:

2 RF carriers : QAM or ATSC or DVB-T or ISDB-T
2 ASI’s Output
MPTS IP Output

Thor Broadcast Transmodulation systems are a 4 RF input modulator and program stream multiplexer with CAM support via 4 CI slots. They are available for QAM (DVB-C), Satellite (DVB-S/S2), and terrestrial (ATSC)(DVB-T) radio frequency RF signal sources. RF signal types can easily be interchanged by removing the modules(you can not upload firmware to change the modulation functionality, this is hardware based). Full configuration and management is available on the front panel LCD and keypad, and remote access and monitoring is available on a dedicated NMS network port for control through a web browser. Program streams available as well as the IP and ASI inputs can be multiplexed and remapped in any order. Independent output pipes for both ASI and IP are fully configurable. Industry standard support for Conditional Access is provided by 4 Common Interface (CI) slots. These slots support CAM modules such as CableCard or any other system using the PCMCIA interface. This platform is ideal for program aggregation and multiplexing in cable TV headends and corporate MATV systems.

Question and Answers

Question:

Hello, I'm looking for some technical assistance. I am an A/V studio consultant working with a TV studio that needs to transport (4) HD-SDI camera feeds to a remote building using their existing CATV provider's passive coaxial I-Net. They need to have the (4) cameras feed into their video control system (at the remote building) as close to real-time as possible so as to allow efficient PTZ of the cameras. PTZ will be happening over a separate 10 MBPS Datalink. I'm looking at your H-1/2/4SDI-ATSC-IPLL to put the HD-SDI signals onto the RF Broadband network and your H-IRD-V3-IP (one for each channel?) to get back to HD-SDI on the other end. Question 1, Do I have the correct/most cost-effective solution in mind; and 2, What will the latency look like after passing through the two devices?

Answer:

Yes you have the correct parts to do that, or you can use the H-4HD-EMS to convert to IP, and the 4x V3-IRD-IP to convert from IP back to SDI.

If you want to use the coax, then the H-4SDI-QAM-IPLL to create 4 RF channels, then 4x the V3-IRD-QAM to convert from QAM to SDI.

Latency would be about 2 seconds more than likely going the IP route; if you convert to RF it would be slightly faster, about 500ms

I know it would not be ideal, but the easiest solution would be to use a single strand of fiber between the locations:

Zero Latency, uncompressed 4x 3G-SDI over one Fiber

Question:

Product recommendations. Could you recommend a modulator. 5 HDMI inputs, a single ASI output. Multiple programs need to be modulated on the same frequency. We are transmitting 5 programs OTA. VHF Ch4 Perhaps a H-12HDMI-QAM-IPLL I require single channel RF input to RF output TransModulators. VHF Ch4 to UHF Ch24 also UHF Ch24 to UHF Ch16 Perhaps a H-4-ATSC-ATSC

Answer:

If you need to modulate 5 programs on one ATSC RF channel, I would recommend
2pcs H-4ADHD-ATSC-IPLL connected together via ASI

The H-4ADHD is a 4 ch HDMI encoder/ ATSC modulator with ASI input and
ASI output, unit has a TS multiplexer built into it.
You can use the first one to produce 4TS. and you can bring the 5th
from the second unit via ASI from the second unit.

I would like to know that In order to fit 5 TS programs into one ATSC
frequency, they would need to be encoded at 19/5 = 3.8Mbps which is a
a little low for decent video quality in MPEG2 encoding, which you must
use for of the air transmission

Currently, the H-4-ATSC-ATSC is no available longer, the only
unit that can be used as a translator is:
H-16ATSC-IP-16ATSC : 16 ATSC to 16 ATSC and IP out
