A few years ago I thought "how smart I am" when I built a smart TV out of a dumb TV, old computer, small server and light apk on my phone to control the newly created dumb-smart-tv, but in fact even this toy project mediately depends on a the linux kernel, drivers, android and a lot of code I cannot even hope to have the possibility to read in my lifetime. The true smart solution would be to have some kind of system on chip that would send via hdmi the proper signal from a source fetched by a sort of curl but with streaming. But then I would expect the source itself to rely on lean software; something like netflix but instead of a web app you would just have some catalog (a printed one?) of the available routes or codes you can send (like a telephone number) to ask for the emission of bytes to your hardware. But then I would ditch software, you would just compose a number on an old analogue phone and plug the video cable in the enclosure to receive your movie, while listening to the audio via the phone speaker.
