Subtitle and Captioning

Subtitles and captions are text overlays displayed on the screen during video playback.

Content Protection

Content protection mechanisms safeguard digital content from unauthorized access, copying, or redistribution. Techniques like Digital Rights Management (DRM) encrypt the content and enforce access controls, ensuring that only authorized users can view or interact with the content.
