This technique relates to:
- Success Criterion 1.2.2: Captions (Prerecorded) (Sufficient as a way to meet G87: Providing closed captions)
- Success Criterion 1.2.4: Captions (Live) (Sufficient as a way to meet G9: Creating captions for live synchronized media)
- Success Criterion 1.2.4: Captions (Live) (Sufficient as a way to meet G87: Providing closed captions)
- Success Criterion 1.2.4: Captions (Live) (Sufficient as a way to meet an unwritten technique)
The objective of this technique is to provide a way for people who are deaf or otherwise have trouble hearing the dialogue in audio visual material to be able to view the material. With this technique all of the dialogue and important sounds are available in a text stream that is displayed in a caption area.
With SMIL 2.0, separate regions can be defined for the video and the captions. The captions and video playback are synchronized, with the caption text displayed in one region of the screen, and the corresponding video displayed in another region.
