A $350 modulator is too much? OK, how about $120 -- https

Is encoding to streaming an option ?? -- https/www.amazon.com/dp/B07CBMZ24P
I guess your definition of "high end" and mine are different. There are $1000 HDMI encoders. $300 seems to be mainstream.

My take on this is, analog TV been around for a loooong time and for a loooong time the only way to hookup anything external to it is via the RF, so they made it inexpensive for ppl to do it?
Nowadays, when ppl hookup external source to TV, we don't think of the antenna, because there are other more direct options. If your mother bought hers right at that time when digital TVs didn't have HDMI/Component/Composite, ooops. What am saying is, am guessing they don't make many of those ATSC modulators to bring the $$ down and market to street Joe consumers.

I agree with your view on cost of consumer electronics. The goal here is to inject HDMI into the coax feed of a DVR using say ch# 3 but still keep the cable tuner usable. This is easy to do with low res video. She used to push home video & photo files to her DVR from a desk top Linux app but the DVR manufacturer killed this functionality.

Not sure what the purpose is to push those files to the DVR rather than the TV? Anything with DLNA (like a Roku) or Android box could be used to access them. The Roku Express + has AV output that could go the DVR.
Since the channel 3 input of the DVR isn't doing to be HD anyway you don't need to inject HDMI. The old analog stuff should work if you can find some.

My issue is related to video and video file input on DVR's. Some DVR's are networked and so they can share files, (push & pull ) them. This particular DVR used to network with PC's as well, but no longer due to the manufacturer changing internal network capabilities, it now excluded PC's. All DVR's have coax input and some have 2 of them (OTA & Cable) and these can be used to insert video for viewing/recording.
Now to your reply: Pushing file to the DVR is for storage & later viewing of Personal Photos and Home movies. If you insert HDTV signal into an HDTV tuner set to CH 3 you will get HD out because the tuner will not down convert to SD. For easier understanding pick another Channel number.
PC-HDMI-Video can be converted to HDTV coax for file recorded & storage but its expensive for the average home owner. Can you offer a reasonable method worth consideration on this point?

The channel number was confusing me since the analog channel 3 isn't the digital channel 3.1.
So you are using the HD in the DVR to store content for later playback.
Then you don't really need to use a DVR. You could substitute an android TV box with enough storage to hold the files. That would allow you to transfer files for local playback or stream them from anywhere on the network using DLNA or Plex. A Roku or Apple TV might work. A computer with HDMI out would work. A smart TV might work if you could push files onto an attached USB drive.
Adapters that lets you use an RG6 cable as an HDMI cable act just like a standard HDMI cable so you can't transfer files over it.

Thanks for your reply! Ah.. the point is to use the DVR and not purchase new equipment or use different software. Local Streaming also isn't needed since this DVR's are networked together and capable of Internet. Now I'm now getting PC file loaded directly to the DVR's but video quality is poor due to the low quality RF modulator. Need a cheap HD capable RF modular.
