Closed caption decoders is a technology that caters to people that are deaf or hard of hearing. It works just like subtitles but the close captioning is hidden as encoded data which is transmitted to the television signal.

Closed caption decoders work by receiving the broadcast signal containing the closed caption text, then converting and displaying this text on the screen in a readable format for viewers. The decoder identifies the closed captioning data embedded in the video signal and presents it as text on the screen in synchronization with the audio content. Viewers can typically adjust the appearance of the closed captions to suit their preferences.
