Timed Text Markup Language (TTML)

Timed Text Markup Language (TTML) is a standard way to create and display timed captions, subtitles, or text descriptions alongside video content. It uses XML-based code to specify exactly when and how text appears on the screen, including timing, positioning, styling, and language details. TTML ensures that viewers can read subtitles accurately synchronized with the audio, enhancing accessibility for diverse audiences. It is widely used in broadcasting, streaming, and digital media to provide clear, well-managed text overlays that improve the viewing experience across different devices and platforms.
