Research techniques
Primary research is where someone finds out something by using techniques that they carry out. This can be done by interviewing someone, using surveys and witnessing. Secondary research is where someone else has used a research technique to discover something. In terms of a news show this can be looking on the internet, looking at books and leaflets.
The reason people research is to turn presumptions to facts. This helps to either make an argument valid or to prove something you have said. For news shows they need researchers to make sure stories are factual and to make sure they have stories.
For example if there was a story about a murder, the news show would have to use research techniques to find out about this story. The techniques they could use are interviews, look at the internet and books, look the police record and emailing.
Multi camera techniques
A multi-camera production is a piece of film that was created by using more than one camera, usually three. The types of film that use this are game shows, the news and Interview shows.
They use multi-camera because it is live which means you cant reshoot to get other angles. So they use, normally, three cameras to get medium close ups of everybody's faces so it looks more interesting rather than just having a long shot which showed everyone but from far away. Multi camera allows cameras to move during production because you can just switch while the camera is being moved.
In a league of their own they start by using an establishing shot of the set, then going to a close-up of the host, then as he talks about the guest there is a close-up of the guests faces.
