NTSC over the air is dead, but NTSC video is far from over. Look at the dashboard of your car, and every car on the road; that back-up camera is NTSC.
Ah, interesting! I figured backup cameras would have been digitized packets vs analog NTSC. Is it just because of low cost/low complexity?
Pretty much. The video is real-time and it’s just a signal and ground. A lot of legacy knowledge and parts make it simple, Quick search on the Tesla autopilot cameras… nope – that’s high speed serial. Obviously you’d want the image data in digital, buffer-able form from the start. So, I’d suspect that the sunset for NTSC on cars is inevitable, it’ll probably be driven (ha ha) by adding safety features to baseline models like collision avoidance and parking assist.
Bit-banging NTSC out of a single microcontroller pin is a fun hack, and the book Racing the Beam really does a nice job of telling the story of the very tight design and programming that went into the Atari 2600.
Cheers!
I like the concurrent video show on YouTube, which means I will be watching the Amp Hour a lot more from now on. I fall asleep mostly when just listening to audio, my bad, not your interesting conversation. I don’t drift off when J can see your facial expressions during the show, plus I like the show-n-tell on screen.
I hope you keep doing the video.
Yes you can have intermitten software faultsm, common source of these faults are concurrency related bugs, like race conditions or other timing errors.
