Observation Details
The trailer video for 5G, accessible via Play Button "Ihre Vorteile im größten 5G-Netz Deutschlands" dialog window, includes informational content, displayed only visually as text.
Remediation Notes
There are two routes to go for remediation.
Arguably, the informational content of the video trailer is already part of the page's text content. If all informational content of the video fits this, the video can be declared a "media alternative for text" and would be exempt of this success criterion. Doing so however requires explicit, clear labelling as such media alternative.
An alternative presentation of the visual contents of the video must be offered, presenting equivalent information either as text alternative or as an audio track
Be advised, route (1) "Media Alternative for Text" only works, if and when all informational content of the video already exists outside the video as text content. If any content is missing in the text content, the alternative presentation in route (2) must be used.
