> 4-A - Caption Playback
> Analog television, digital television and tuners, computer

> requirements for analog television receivers) and 47 CFR
> 15.122 (Closed caption decoder requirements for digital
> television receivers and converter boxes) must provide
> support for TV closed captions and open captions.
> Such equipment must either pass TV caption data to the
> caption decoding circuitry of analog and DTV displays for
> decoding as displayed text, or decode TV caption data and
> pass on a decoded ("open-captioned") video signal to the display.
> 2. Products that do not fall under the regulation of the U.S.
> Federal Communications Commission (FCC), including personal
> video display devices and software players, must provide
> support for a functional equivalent to TV closed captions.
