I'm in need of info about television studios.

First, some background. The studio in question is in a third-world country. The studio itself would be bare-bones in style (furniture and such) but with up-to-date hardware.

1. What personnel would be needed to get a live interview in the studio (basically two talking heads) on the air?

2. What is the equipment needed to get such a show broadcast?

For personnel, I figure a director, a studio tech, and a couple cameramen. Is that all?

Hardware:
- Cameras. Are the big ones that take two people to move around still in use?

- What's the big console with all the slide switches on it called? How many people are needed to operate one?

- What other hardware is necessary? (Besides transmitter and antenna. Got that covered already.)
