All Call
A diagnostic procedure that causes a single physical input to be switched to a range of physical
outputs, for a specified component, with a single command.
Example: Assume the existence of a component RED which spans physical inputs 1 through 8 and
physical outputs 1 through 8 on a routing switcher. All call could be used to switch physical input
3 to physical outputs 4 through 8 with a single command.

Baud
The number of signaling elements that occur each second.
At slow speeds, only one bit of information (signaling element) is encoded in each electrical
change. The baud, therefore, indicates the number of bits per second that are transmitted.
For example, 300 baud means that 300 bits are transmitted each second (abbreviated 300 bps).
Assuming asynchronous communication, which requires 10 bits per character, this translates to 30
characters per second (cps).
For slow rates (below 1,200 baud), you can divide the baud by 10 to see how many characters per
second are sent.
At higher speeds, it is possible to encode more than one bit in each electrical change. 4,800 baud
may allow 9,600 bits to be sent each second. At high data transfer speeds, therefore, data
transmission rates are usually expressed in bits per second (bps) rather than baud. For example, a
9,600 bps modem may operate at only 2,400 baud.
Black Burst
A composite color video signal which has sync, color burst, and black video. It is used to
synchronize other video sources to the same sync and color information.
