Television news consists of several different elements, introduced by a news presenter or presenters. The presenters read 'links' and do interviews.
Most news stories come in the form of short 'packages'. These are pre-recorded reports usually lasting from one to five minutes. News reporters gather and edit together interview clips, pictures and their own 'pieces to camera' to tell a story. They script and record a 'voice-over' to explain the pictures and link the elements together.
Some stories are done as live reports. This can be a reporter on the scene of a story either being interviewed by a studio presenter (sometimes known as a 'two-way'), a reporter interviewing one or more other people, or simply live pictures and sound of an event. The sound and pictures are sent back to the TV station via fixed cable links, bounced off a satellite from a vehicle carrying a satellite dish (a 'sat truck'), or sent through microwave radio transmissions from a vehicle carrying a microwave transmitter. With the growth of "rolling news" channels the use of live material has increased enormously and TV reporters are now often judged as much on their ability to perform live in front of a camera as on their package-making or writing skills.
TV news programs are put together by producers, who decide what goes in and what gets left out, and how long and in what form each story is presented. They put together 'running orders' - a list of the stories in what they decide is the right order.
A separate news editor is often responsible for co-ordinating the gathering of material.
