Checkpoint 7.3 User Controls for Captions and Audio Description

Where ICT primarily displays materials containing video with associated audio content, user controls to activate subtitling and audio description shall be provided to the user at the same level of interaction (i.e. the number of steps to complete the task) as the primary media controls.

Rationale

The European standard specifies requirements for the processing and display of captions and audio descriptions during playback. 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 7.3 User Controls for Captions and Audio Description for more information (external link to EN 301 549 toolkit).

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.

Development Techniques

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.

General techniques

Instructions: Complete both techniques.

  • Providing user controls to display captions at the same level of interaction as the primary media controls and
  • Providing user controls to activate audio descriptions at the same level of interaction as the primary media controls

Note: For compliance reporting, where the requirements of 7.3 User Controls for Captions and Audio Description are met, the following checkpoints can also be considered to be met:

Mobile Native (iOS) techniques

There are no specific Mobile Native techniques for this checkpoint. Refer to the General techniques section.

Eclipse techniques

There are no specific Eclipse techniques for this checkpoint. Refer to the General techniques section.

Windows-based (MSAA+IA2) techniques

There are no specific Windows-based (MSAA+IA2) techniques for this checkpoint. Refer to the General techniques section.
