Where ICT has a mechanism to play audio description, it shall preserve the synchronization between the audio/visual content and the corresponding audio description.
The European standard specifies requirements for audio description processing technologies. These need only be addressed for software applications that are media players or contain embedded players. Other applications should mark this N/A (not applicable).
Refer to Requirement 7.2.2 Audio Description Synchronization for more information (external link to EN 301 549 toolkit).
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 chapter 7 of EN 301 594, which covers the actual delivery of synchronized audio descriptions during playback by the media player.
Note: The IBM compliance reporting system will be able to convey compliance status with European EN 301 549/Mandate 376: Accessibility requirements suitable for public procurement of ICT products and services in Europe. Revised Section 508 checkpoints cover most of the EN 301 549 requirements. However, this is one of several additional checkpoints that will need to be completed to fully report compliance with the European standard.
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.
There are no specific Mobile Native techniques for this checkpoint. Refer to the General techniques section.
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.
