board, they appear in uppercase, boldface characters. For example, the keyboard con-

done using the shift button in combination with some other button. A plus (+) symbol
indicates this. For example, you might be asked to enter SHIFT+PIPS . This means press

A Source is a physical device, such as a VCR, that provides a video and/or audio sig-

An Output displays or records a mixed signal (such as the video on one channel, a
transition, and the video on another channel) on an output device. The output device
might be a recording VCR or a live broadcast signal.
