Record model and software requirements
Apple's current Canadian iOS27 guide qualifies generated subtitle features by supported iPhone hardware, software, app and language. Check the actual device and offered controls rather than assuming every iPhone has the same feature set.
This page does not turn a platform capability into a promise about a particular IPTV player or programme. A supported app and source remain part of the requirement.
Read the text origin
The current guide describes Transcribed and Translated labels for generated text. These differ from a supplied subtitle or caption track in the programme. Inspect the actual list rather than inferring origin because text appeared automatically.
Generated words can help a task but are not evidence that the broadcaster or service authored a complete accessible caption track. Translation also adds a different processing stage from same-language transcription.
Check the intended task
Choose a familiar permitted passage and identify the required language, speaker information and sound cues. Compare the offered supplied track with the relevant generated option where both exist.
Do not judge suitability from one easy sentence. Names, overlapping dialogue and non-speech information can expose differences relevant to the viewer. Keep the programme edition constant so the comparison concerns text origin rather than a different cut.
Inspect automatic activation separately
Apple documents automatic subtitle conditions in supported apps, including mute or skip-back related choices. Record which option is enabled before reporting that captions appear unexpectedly. Automatic appearance and text origin are separate facts.
A global preference can affect the interface differently from the player's own track choice. Change one control and repeat the same action.
Report the actual label and result
Give support the device, iOS version, app, text label and the task that fails. Distinguish absent controls, inaccurate generated text and an unavailable supplied track.
This is a documentation-based feature assessment. No generated caption accuracy, service catalogue or physical device was tested, and the page does not certify an accessibility standard or promise all languages and regions.
Do not transfer a phone result to the TV
Generated text on a supported iPhone does not establish the same feature on a connected television, casting receiver or another household device. Record where the text is rendered and assess the intended viewing route separately. A screenshot showing words on the phone is not evidence that the provider embedded those words in the programme or that an external player can select them as a supplied track.
Sources and scope
Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
