G93: Providing open (always visible) captions

Applicability

Any synchronized media technology, even ones that do not support closed captions.

This technique relates to:

Description

The objective of this technique is to provide a way for people who are deaf or otherwise have trouble hearing the dialog in audio visual material to be able to view the material. With this technique all of the dialog and important sounds are embedded as text in the video track. As a result they are always visible and no special support for captioning is required by the user agent.

NOTE: Captions should not be confused with subtitles. Subtitles provide text of only the dialog and do not include important sounds.
