CC (Closed Captioning)

Closed Captioning (CC) is a service that displays written text on a screen to represent spoken dialog, sound effects, and other audio cues in a television program, movie, or digital media. It’s designed to help viewers who are deaf or hard of hearing understand the content, but it can also be useful in noisy environments or for language learners. CC is "closed" because it can be turned on or off by the viewer, typically through a menu or remote control. The captions are synchronized with the audio, providing a real-time or pre-recorded textual version of the audio information.
