"The appropriate equipment" being any television younger than about fifteen years old. Subtitles and SAP (Second Audio Program -- dubbing into another language) are a very regular feature at least of cable TV in the U.S. I'm way out of touch with whatever those twentieth-century slowpokes, the large TV networks, are currently doing, as I've lived ten years in an area that gets very poor VHF and UHF reception -- the antennas are all over in L.A., and there aren't hardly any repeaters to get the signals over the intervening mountains. Even medium-wave AM radio is weak and noisy.
