The Theater is the study in grand and large movement, but the Television Studio is a study in the small movement. Where in the theatre you the viewer are well back from the performer, television places the performer so close even the smallest motion or twitch is noticed. So the exception for the performer will be in the manner of acting. With this exception all of the disciplines of the theater apply to the television studio, plus all of the technical video requirements.
Lets start with the simplest studio.
Its a room with lights and cameras. You dont have to have the big television studio with the fancy lights and expensive cameras, the elaborate audio system and all that, to produce a good program. Look at the daytime talk shows. People setting on couches, or at tables, or a cooking show - why cant you use your own kitchen. My point is you have a camera, you have a house and therefor you have your own studio.
