Background

Those can be identified by including elements having an attribute value containing a media file format, such as .mov, .rm, .ram, .asf, .swf, .dcr, .avi, .mpg, .mpeg, .mp4, .m4v, .webm, .flv, .isma

XPath: //*[contains(@*,'.mov') or contains(@*,'.rm') or ... ]

Open question: There may be other sources of time-based media,

e.g. animated <canvas>: [This clock] or <svg>: [This animation]


Step 1

Test mode: earl:manual

Check that the content is a video containing an audio-track.

Step 2

Test mode: earl:manual

Check that the video-only content is prerecorded.

User input question

Item presented to the user: Whole page

Question: Is the video-only content prerecorded?

Answer options: "yes/no"

Answer options: "yes/no"

Help text: If the video-only content is purely decorative and does not contain relevant information for the context of the web page select “Yes”. Else select “No”.

else continue with #Step 4

Step 4

Test mode: earl:manual

Check that there is an alternative version available for the prerecorded video-only content.

User input question

Item presented to the user: Whole page

Question: Is there an alternative version for the video-only content available?

Answer options: "yes/no"

Help text: The alternative version may be a textual alternative or an audio alternative. If such is available directly near the video-only content select “Yes”. Else select “No”.

Repair suggestion: none

Properties of the test step:

  • context-sensitive = yes
  • user interaction (with the web content) required = yes


If yes, continue with #Step 5

Step 5

Test mode: earl:manual

Check that the alternative version has the same information presented as the video-only content.

User input question

Item presented to the user: The video-only content and the alternative version

Question: Does the alternative version sufficiently describe and convey all information of the the video-only content?

Answer options: "yes/no"

Help text: The alternative version needs to tell the same story and present the same information as the prerecorded video-only content. It should not contain more information than the video-only content itself. If both is true select "Yes". Else select "No".
