1) Correct. Our units will modulate HDMI inputs and send out the signal as Clear QAM so no STB is necessary, so long as the televisions have RF input decoders built into them.
2) Yes, generally speaking televisions have RF decoders/tuners built into them. Hence why you can plug in RF cable and get a picture without an STB, because they decode Clear QAM(cable) and ATSC(Antenna); which is what televisions have been using for decades; however I would point out that many new models of tv's coming onto the market don't have RF inputs anymore.
The cable companies encrypt their QAM channels, so you would need to use a particular STB which is supported by that cable company.
Our STB supports CLEAR QAM without any encryption.
The easiest way to check if your QAM is encrypted or not, please connect the CAble TV feed to your Tuner TV, if the Tv scans channels OK, then you have Clear QAM, if not your Qam is encrypted and you Must use Cable Tv STB.
There is no other way around it.
Since you have a paid service, Comcast, the QAM signal is encrypted
and the only way to get that signal is through their products. We only
offer Clear QAM or ATSC tuners.
You'd need to contact Comcast directly and get pricing for an
additional Set top box.
To convert coaxial cable (coax) to HDMI (High-Definition Multimedia Interface), you will need a coaxial to HDMI converter or decoder like Thor H-STB-ATSC-QAM . This device converts a coaxial cable signal into an HDMI signal that can be displayed on an HDMI-compatible device such as a television or monitor.
To use a coaxial to HDMI converter, you will need to connect the coaxial cable source (such as a cable box or satellite receiver) to the converter using a coaxial cable. The converter will then convert the coaxial cable signal into an HDMI signal that can be displayed on an HDMI-compatible device.
There are several types of coaxial to HDMI converters available, including both analog and digital converters. The choice of converter will depend on the specific requirements of the application, including the distance that the signal needs to be transmitted and the data rate of the signal.
It is also important to note that HDMI and coaxial cable signals are not interchangeable, and a device is required to convert between the two formats. A coaxial to HDMI converter is used to convert coaxial cable signals into HDMI signals, while an HDMI to coax encoder is used to convert HDMI signals into coaxial cable signals.
An ATSC (Advanced Television Systems Committee) or QAM (quadrature amplitude modulation) set-top box (STB) is a device used to receive and decode digital television signals transmitted over the air or through cable.
An ATSC STB is used to receive and decode digital television signals transmitted using the ATSC digital television standard. ATSC STBs are commonly used in North America, South Korea, and other countries that use the ATSC standard.
A QAM STB is used to receive and decode digital television signals transmitted using the QAM digital television standard. QAM STBs are commonly used in cable television systems, and are capable of receiving multiple channels of video, audio, and other data over a single coaxial cable.
Both ATSC and QAM STBs are equipped with a tuner that is able to receive and decode digital television signals, and a display interface that allows the signals to be displayed on a television or other display device. They may also include additional features such as digital video recording (DVR) capabilities, on-demand content, and interactive services.Our H-STB-ATSC-QAM is very unique on the market because display VCT - Virchual channel numbers correcty according to the SMPTE CVCT and TVCT standard.
I have one more question: Is your application intended for local RF coaxial in-house distribution, or is it dedicated to a cable TV company?
1) Based on your answer, the H-8TS-ATSC/QAM 8-channel QAM to IP and ASI transcoder might work for you.
The unit has 8 inputs and can transcode 8 SD or 4 HD programs. Since you have 12 HD transport streams, you would need 3 devices, as each unit can only transcode 4 HD programs.
Here is the link to the unit: H-8TS-ATSC/QAM Transcoder.
2) Another, less expensive option would be re-encoding. You could use 12 small QAM set-top boxes (STBs) we carry—H-STB-QAM-ATSC—to convert them to HDMI format.

Then, use our 8+4 channel HDMI encoder/modulators, H-THUNDER-8 and H-THUNDER-4, which output 8/4 individual RF channels, and combine them together.
H-THUNDER-8 -8 channel
H-THUNDER-4 - 4 channel

High Definition IP Set Top Box for decoding IP streams from an encoder. This unit can be easily mounted behind a display to bring HDMI connectivity to remote locations for displaying network content.
The H-IP-SDI is a Managed IPTV to SDI Video Decoder that can intake a TS signal and decode almost any incoming HEVC, H.265, H.264, and Mpeg-2 stream at up to 1920x1080@ 60fps and 3840x2160@ 30fps. It can decode various protocols including IPv4/v6, TCP, UDP, HTTP, HLS, RTP, RTSP, RTMP, FTP, and IGMP(Multicast). This will allow you to interface and broadcast from all types of websites, encoders, servers, and hosts; from YouTube to private UDP streams. The unit comes equipped with a GUI interface so you can access it remotely.
