A Parisian, Ravel is broadcast worldwide (9)
I believe the answer is:
universal
'worldwide' is the definition.
('universal' can be a synonym of 'worldwide')
'a parisian ravel is broadcast' is the wordplay.
'a parisian' becomes 'un'.
'broadcast' is an anagram indicator.
'ravel'+'is'='ravelis'
'ravelis' anagrammed gives 'iversal'.
'un'+'iversal'='UNIVERSAL'
(Other definitions for universal that I've seen before include "Ubiquitous" , "Belonging to the whole world" , "Of worldwide scope" , "Common" , "affecting everyone" .)
