TIME BASE
9 – 88 Glossary
This glossary contains explanations of the most significant terms used in
this manual.
Address SMPTE/EBU Time Code Address – also called Time Code value –
is the precise address in the Time Code data stream.
AES-3 A method of synchronization using an AES standard.
AES/EBU Professional standard for transmission of 2 channels of Digital Audio
data as well as controller data, developed by the Audio Engineering
Society (AES) and the European Broadcast Union (EBU).
Analog Audio A way of recording and playing back audio by using electrical current
changes to represent audio waveforms.
ATR Audio Tape Recorder.
Bandwidth The range of frequencies present in an signal.
Binary Numerical
System System, which only uses 0 and 1 to represent numerical values. The
Binary system is used for Digital Audio, SMPTE, MIDI and computer-
based data formats.
Biphase Encoding
(Biphase-Mark) Encoding of LTC-SMPTE/EBU Time Code. The binary numerical values
0 and 1 are provided with extra clock information and set in a frequency
range which allows them to be recorded on analog audio tape.
BIT Abbreviation for Binary Digit – set to a value of either 1 or 0.
BNC Bayonet Nut Coupler – Standard connection for transferring video
and high frequency clock signals.
Byte A group of 8 Bits.
CL Clock Reference or Clock Source or Reference Source describes
the signal used to specify the reference rate at which Time Code and
the Clock Generator operate. This can be seen as the system’s time
base. The Reference source can be an internal crystal, an external
video clock, external Word Clock, an AES/EBU signal or the Time
Code reader.
DAW Digital Audio Workstation – Computer based hard disk recording
and editing system
Decibel (dB) Unit of measurement and display of amplitude – relative and
logarithmic.
DF (D) Abbreviation for Drop Frame.
Differential Output Output amplifier designed to produce two totally identical, yet phase
inverted signals – “electronically balanced”.
