Submitter's Name: David MacDonald Submitter's Email: david@eramp.com Technique ID: UNKNOWN Short Name: Gxx: Using a static text alternative to describe a "talking head" video. Technique Category: General Techniques Success Criterion Reference: UNKNOWN Description: The purpose of this technique is to provide an alternative to synchronized media that has no time based important information contained in the video portion of the media. This particularly applies to "talking head" videos where a person is talking in front of an unchanging background, such as a press conference, company president talk, or government announcement, etc... In this case there are no "important visual details" which require audio description. Audio Descriptions is not necessary when there is one person speaking against an unchanging background because there is no time-based visual information in the video that is "important" to the understanding of the content. The environment is static and therefore can be described in a non-multimedia static format such as alternative text that is programmatically associated with the video. All that is necessary in this case is a static text alternative which would contain a general description of the context of the environment, any opening/closing credits, and any text that appears in the bottom of the video with the name of the speaker, and other basic information, if these are seen on the screen, and cannot be heard in the audio. This technique does NOT apply to a situation where there are multiple speakers and the speakers are identified on screen with visual text as they speak. This would require Audio Description if there is room between the speaking dialogue. Example 1 Head: A video of a CEO speaking to shareholders Example 1 Description: A CEO speaking to shareholders from his office. The video has a title page at the beginning of the video giving the date. When the speaker begins, there is a strip of text at the bottom of the video saying "John Doe, President of XYZ Cooperation". At the end of the video are title credits that say "produced by the Honest TV Productions Ltd. As an alternative, there is a paragraph below the video which is associated with the video file using aria-describedby which says: "July 22, 2011, John Doe, President of XYZ cooperation, speaking from his office. Video produced by produced by the Honest TV Productions Ltd." Additional Notes: This also appleies to 1.2.3 Once WAI ARIA described by techniques are finished, this technique would linnk to that as a related technique. No guidelines reference was submitted!
