How did the TV know what closed captions to show when VHS tapes were played?
In: Technology
I didn’t even know this was a thing.
If you couldn’t turn them off I’d assume it was just a part of the video. If you could turn them off/on there would have to be an encoded signal that the vcr could understand and selectively put that “layer” over the program material.
Hopefully someone else can do better than me.
