This might be a double definition.

'public broadcaster' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'one who has viewers streaming?' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

Can you help me to learn more?

(Other definitions for crier that I've seen before include "Town's announcer" , "court official" , "Old-time announcer" , "One making public announcements" , "Officer making announcement" .)
