TEITAC Members --

For the sake of orderliness, please refrain from making a decision until I
can be sure that this is final language and that language is put into the
Wiki.

Subject: RE: [teitac-committee] Definition Consensus Decision: Captions



WCAG used to use this definition. However



- Sean from Microsoft pointed out that captions often contain non-text
equivalents.



- Andrew Kirkpatrick pointed out that closed captions do not need to be
images of text embedded in video



Based on that input and other comments made to WCAG draft the WCAG
definition for Captions is as follows:

(Note "audio description" changed to "video description" to match TEITAC
useage.)



Suggest using this definition - or at least offering it to the Group to see
if there are problems with it.






captions (WCAG 2.0)


synchronized media or text equivalents for audio information including both
dialog and non-dialog audio information

Note 1: Captions are similar to dialog-only subtitles except captions convey
not only the content of spoken dialog, but also equivalents for non-dialog
audio information needed to understand the program content, including sound
effects, music, laughter, speaker identification and location.

Note 2: Closed Captions are captions that can be turned on and off in some
players.

Note 3: Open Captions are captions that cannot be turned off. For example,
if the captions are visual equivalent images of text embedded in video.

Note 4: Captions should not obscure or obstruct relevant information in the
video.

Note 5: In some countries, captions are called subtitles.

Note 6: Video descriptions can be, but do not need to be, captioned since
they are descriptions of information that is already presented visually.

Subject: [teitac-committee] Definition Consensus Decision: Captions

Following is the definition for Captions. If you do not agree that this
definition is acceptable, please reply and state your reason. Please note
that captions previously achieved committee consensus. However, to better
clarify the definition, Captions has been revised as follows:



Captions



"Synchronized text equivalents for audio information.

Note 1: Captions are similar to dialog only subtitles except captions convey
not only the content of spoken dialog, but also text equivalents for other
(non-spoken) audio information including important sound effects, music,
laughter, speaker identification and location.

Note 2: Captions can be real text that can be turned on and off (closed
captions) or images of text embedded in video (open captions).

Note 3: Captions should not obscure or obstruct relevant or key information.


Note 4: In some countries captions are called subtitles."
