Applies to: A household compares different accessibility labels on one edition.
The useful distinctions
- Captions provide access to meaningful audio information.
- Audio description addresses essential visual information absent from the main audio.
- The presence of one format does not establish the availability of the other.
Map the need to the information
A caption label may be useful to a viewer who needs speech and sounds represented as text. A different viewer may need silent action or on-screen text conveyed through audio or another accessible format. These are different information gaps. Start from the gap rather than treating an accessibility badge as a promise of every access feature. A household can also need both, and those requests should remain visible together.
Ask independent availability questions
For the exact programme edition, ask what caption format is confirmed and whether a described edition or suitable alternative is supplied. A positive answer to the first question does not close the second. If a short sample is possible, choose one audio-dependent moment and one silent visual action. Record only what those samples establish, leaving any untested part open instead of announcing complete accessibility from one successful feature.
Hypothetical worked example
A fictional edition AC-9 offers a text label described as English captions. Viewer A checks whether it conveys an off-screen alarm. Viewer B asks how a silent exchange of documents is conveyed without seeing the picture. The caption label addresses the first enquiry only if its actual coverage is suitable. The second still needs confirmation of audio description or another useful visual-information alternative for the same edition.
A focused way to proceed
- List which information the viewer needs conveyed.
- Record caption and described-audio labels separately.
- Check an appropriate sample for each requested function if available.
When to stop or ask for help
Request the missing access format explicitly and avoid treating a single accessibility label as a complete format inventory.
