The H-4ADHD-XXX-IPLL modulator family from Thor broadcast is designed to handle even more applications than any other 4 channel chassis system that has come before.  This system has all the previous award winning features found in Thor Broadcast modulators, as well as several new additional functions for added applications and flexibility. The platform provides 5 full RF carrier outputs for generating channels from content ingested through the ASI input. Encoding in either MPEG-2 or H.264 is provided for 4 crystal clear video streams up to 1080p60 each.

Bitrate is fully adjustable from 1.5 - 19 Mbps, and a variety of audio codecs are available. Standard audio encoding in MPEG-2 AAC and MPEG-4 AAC are provided, as well as a licensed Dolby AC/3 audio codec. Audio sources can be selected from either embedded HDMI or Analog RCA ports.  For Surround sound, digital audio inputs can be set to "pass through" mode to preserve 5.1 and 7.1 audio that is encoded already in Dolby compatible format.  Two mirrored ASI outputs are provided for broadcasters for added flexible in distributing the content generated by the 4 encoders.

The ideal solution for Professional Stadiums and Live Events. Used in more Collegiate stadiums for sports and distribution than any other model. 

Programs input via ASI can also be multiplexed and remapped to the ASI output, adding yet another function to the unit as an ASI multiplexer.  IPTV is not neglected in any way.  All four encoded programs can be mapped to unique IP address outputs and ports in either UDP or RTP format.  The IP output can be configured to strip null packets to reduce network bandwidth or preserve the constant bit rate (CBR) packet stuffing normally preferred by television systems.  All four channels can be independently configured for either multicast or unicast outputs. Closed captioning is supported on a dedicated analog 608 CC port with RCA connector, an industry standard for line 21 captioning systems. Any 720 or 1080 line standard video signal in either HDMI or Component YPbPr format can be used for each of the four channels. Just like all other professional Thor modulator chassis, this system can be configured with firmware for either QAM, DVB-C, DVB-T, or ATSC channel format output.

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
