Where user controls are provided for program selection, ICT shall provide user controls for the selection of audio descriptions at the same menu level as the user controls for volume or program selection.
Controls related to audio descriptions are just as important and useful as controls for volume and language functions. It should be easy and obvious to find and access all associated audio description controls.
Note: 1.2.5 Audio Descriptions requires that audio descriptions are provided. That checkpoint stipulates that when creating content, the author must ensure meaningful video content has been described and is captured in a format that can be used to provide synchronized audio descriptions. Those requirements, covering the content of the audio descriptions, are complementary to 503.4.2, which covers the controls for turning audio descriptions on and off provided by the media player.
Note: Review the General techniques as well as other tabs applicable to your technology. Prioritize the use of technology-specific techniques, and implement the General techniques as needed. You are always required to find, understand and implement accessible code techniques to meet the checkpoint. The documented techniques and supplements are not exhaustive; they illustrate acceptable ways to achieve the spirit of the checkpoint. If numbered, techniques are in order of preference, with recommended techniques listed first.
Each item in this section represents a technique deemed sufficient for meeting this checkpoint.
- Providing controls for audio description at the same menu level as volume or program selection
For compliance reporting, where the requirements of 7.3 User Controls for Captions and Audio Description are met, 503.4.2 can also be considered to be met.
In addition to the General techniques, the Mobile Native iOS techniques in this section represent techniques deemed sufficient for meeting this checkpoint.
- Using the standard video viewer when displaying an audio-described video in an iOS environment
There are no specific Eclipse techniques for this checkpoint. Refer to the General techniques section.
There are no specific Windows-based (MSAA+IA2) techniques for this checkpoint. Refer to the General techniques section.
