This service
Streams is the service in front of you. The title, the clock, and the places you are sending to belong to this service.
Captions
Captions can run both ways, for example English and Yoruba. Cinema is the usual look: centred, with a soft shadow. A person can speak one language while the desk speaks another.
After refresh
Viewers keep Hear and Read after they refresh. You do not turn them on again from Settings unless you want a different look or language.
