Universal Modulator that's unique design is the most capable Hybrid on the market.

Up 8 Channels of HDMI or SDI inputs allow you to select either or in the options menu on the simple and creative GUI. This modulator by Thor has independent input cards for flexibility for Digital Modulation because it eliminates the need for HDMI to SDI or SDI to HDMI converters. Simply select which source you want to use and input the channel frequency creating an automated encoding headend device that can clean up your headend and modulation distribution infrastructure.

Each channel can individually be selected as an HDMI or SDI input, it could be switched on the fly using front panel buttons or Thor's dynamic proprietary Web interface. Each of the 8 channels of RF output can be set totally independent as a frequency AND modulation standard. For example, you can input 4 channels as HDMI and set to QAM output and then input 4 channels of SDI and as ATSC output. This is a flexibility that hasn't been seen before on the market creating a whole new generation of standard for encoder modulation products

The New THOR HYBRID Modulator has an NMS port and LCD display with simple D-Pad buttons for control and easy setup on the fly. It includes and supports the majority of Modulation standards found in the world; like Clear QAM Annex A and Annex B, ATSC-8VSB, DVB-T, and ISDB-T. The Hybrid modulator support MPEG2 video encoding up to 25Mbps/channel, Audio AC3 or MPEG1 Layer 2, and AAC, Thor's world-famous Low Latency, and VCT -Virtual Channel Numbers for increased flexibility. Each CATV RF channel can be set individually, so it does not have to be in a linear 8ch block, feel free to spread out your new custom RF channels all over the existing RF spectrum in your modulation lineup.

Question and Answers
I'm in the process of replacing the 480i analog CCTV system on our ship with new 1080 ipcams. Each channel on the modulator is connected to the HDMI output from a raspberry pi. The pi are configured to do one of three things: 1. stream the rtsp feed from an ip camera. This is especially important for deck operations so the bridge can see what is happening. 2.VCN into another computer on the ship and display what that computer is doing (multibeam sonar, USBL, echosounder, Navigation, etc) 3. Run a custom data display showing real-time science data. In addition, we have a 6000m depth rated ROV, which puts out HD SDI video. This goes into an SDI input so people on the ship can watch. The video quality is good, much better than our old analog system. We will be buying a second modulator unit, perhaps just HDMI. A quick question, is there a setting I can massage to get the modulated output on a non-subchannel? e.g. just plain channel 66, not 66-1.

In order to have single-digit channel without subchannel, There is a trick you can use it but please test it, not all the TV's support it. In the Major channel number please type 1008, it will be ignored by TV's and on the Minor channel put the channel you require, and just this number will be displayed.
Please explain operation Thor H-Hybrid-RF MPEG2 in ISDTb H.264 norm in Chile with local TV set tuners, similar to Brazil and Peru

according to our experience with the countries using ISDB-T, even ones with H.264 as the standard, the TV tuners are universal and can decode H.264 and MPEG2 as well. We send many devices to Brasil and Peru, and customers are very happy with the performance. A similar case is in the US, even if the standard for ATSC and DVB-C Annex B is MPEG2, most new TV's can decode MPEG4(H.264), Transport Stream. Also, our company has a very good return policy in case it would not work for your customers.
