"tunnel data over a digital television system" reminded me of this hack utilizing YouTube video as a data storage warehouse. The right encoding/decoding scheme could theoretically turn those digital video streams into a data stream. https://hackaday.com/2023/02/21/youtube-as-infinite-file-storage/

Cale - Yeah, I remember that hack. And before that, there was a board that could encode data into a video stream so that you could use an off the shelf video recorder (VHS) for storage of large files (that made sense back when hard disks were small and expensive).

I think that dedicated video hardware and modulations made sense in an earlier era when computers weren't very powerful (at least versus dedicated video chips produced at massive scale for consumer use). Now that we can do video in software and cheap, commodity, embedded computers like Raspberry Pi 5, coupled to cheap D/A and A/D converters, I think it makes more sense overall to create general purpose data networks that can carry all kinds of data. Oh wait... we did - the Internet running TCP/IP, UDP, etc.

Our problem in Amateur Radio is that we think too small most of the time, and we don't think of all that we can be doing with the vast radio technology privileges that we have. We can be doing at least 1 Mbps off the shelf with New Packet Radio for example. I'm pretty sure we can do at least SOME video comms over such a link... which can also do data.

That said, the Amateur Radio video folks are rabid about their favorite mode and they put their effort, money, time, and resources behind it. The only equivalent that I've found in Amateur Radio for data that's comparable to the video folks is the AREDN folks, and yeah, you can easily do video over those networks (including at high resolution, at least HD, and I've seen 4k discussed).
