Technique ID: UNKNOWN
Short Name: Including and playing dialogue only subtitles encoded in the closed caption stream of video
Technique Category: General Techniques
Success Criterion Reference: UNKNOWN

Applicability:
Signing is used in small communities and is not understood by others.
Like other natural languages completely different forms emerge. For
example some deaf people in Australia understand Auslan, but do not
understand US (ASL) or UK (BSL) signing. They all understand written
English as used in subtitles. Signing is only used for face to face
communication within those small communities. If an Auslan
&lt;http://www.auslan.org.au/&gt; speaker goes to the US or UK then they
are in the same position as an English only speaker in East Germany.
They have to write down notes too.

UA Issues:
Signing is an issue for User not their Agent.

Many broken video players do not play closed captions which is a
User Agent issue.

Description:
Subtitles for with dialogue alone should be sufficient.
We don&#039;t need &quot;Loud bang&quot; when is obvious that some one has been
startled. It is such overload that makes subtitles hard to follow.
The option of selecting dialogue only subtitles should be a requirement.
This can be including in the existing video closed caption stream.

Related Techniques:

Test Procedure:
Turn your speakers off or like many people your computer
already does not have speakers or the OS boots up with sound off
(-inf dB rather than 0 dB) so the speakers won&#039;t work anyway.
(There is no sound in GNU/Linux by default. Blinkies hate this.)

Expected Result:
Does the video make sense without audio? Yes=PASS
No
Did you have to make the speakers work and then did it make sense? Yes=FAIL
No
NORMAL

Test File 1:
Grab any video and try and get subtitles to display.

Test File 1 Pass/Fail: fail

Test File 2:
Yet to find one, but some make some sense even when dialog is not known.

Test File 2 Pass/Fail: pass
