Hi, dear community!

I'm currently working with the text about features of broadcasting. Can you please help me out with some definitions?

1. I don't quite understand what 'packaged content' means. In the text, it is compared to 'live content'. So is 'packaged content' just content that is prepared in advance?
2. 'Self opt studio' (in radio). Is it a little studio where one person is doing everything? Performs in front of the microphone, sets the sound, operates opt-in and opt-out?
