Closed captions
Enable closed captioning support in your broadcast playout solution.
Closed captioning (or CC) is the process of displaying text on a video screen or any visual display to provide the viewers with a transcription of all significant audio content, such as dialogue and sound effects. Captions are synchronized with the video image to ensure full understanding. In contrast to open captions, closed captions can be turned on/off by the viewer.

Closed captioning is obligatory for the majority of programming on broadcast TV in the United States, Canada and China, as well as in most Latin American countries.
