AC
Alternating Current. Current that is continually changing in
magnitude and periodically in direction from a zero reference
level.
A/V
Audio/Video.
AES
In cryptography, the Advanced Encryption Standard (AES) is
an encryption standard adopted by the U.S. government. The
standard comprises three block ciphers, AES-128, AES-192 and
AES-256, adopted from a larger collection originally published as
Rijndael. Each AES cipher has a 128-bit block size, with key sizes
of 128, 192 and 256 bits, respectively.
ASI
Asynchronous Serial Interface. A streaming data interface
which often carries an MPEG Transport Stream.
An ASI signal can carry one or multiple SD, HD or audio programs
that are already compressed, not like an uncompressed SD-SDI
(270Mbs) or HD-SDI (1.45Gbs). An ASI signal can carry varying
amounts of data but is always padded to run at a fixed line rate of
270 Mb/s.
Amplification
The process of increasing the strength (current, voltage or power)
of a signal.
Amplitude
The level of an audio or other signal in voltage or current. The
magnitude of variation in a changing quantity from its zero value.
Amplitude Modulation
Modulation in which the amplitude of the carrier wave is varied
above and below its normal value in accordance with the
intelligence of the signal being transmitted. Also called AM.
