Couple quizzically raised one’s casually viewing broadcast (8)

I believe the answer is:

eyebrows

'couple quizzically raised' is the definition.
(someone may raise their eyebrows quizzically)

I don't understand the rest of the clue.

(Other definitions for eyebrows that I've seen before include "part of one's features" , "these may have been plucked for beauty" , "that may be surprisingly elevated" .)

I've seen this clue in The Times.
