Caption provides structured representation of video/audio captions for:
|
|
- WCAG accessibility compliance
|
|
- Multilingual subtitle support
|
|
- Caption metadata (language, format, availability)
|
|
|
|

**USE CASES**:
|
|
- Video captions for hearing accessibility
|
|
- Subtitles for multilingual content
|
|
- Closed captions vs. open captions distinction
