Micrometer (former name - micron): A unit of length equal to one
-6
millionth (10 ) of a meter.
The term for the Electrical Gigabit Ethernet interface. This is the
most common interface for Gigabit Ethernet. Most Gigabit-enabled
PCs and equipment use this interface.
A technique used when converting film material (which operates at
24 pictures per second) to 525-line video (operating at 30 pictures
per second).
Digital video coding method in which the color difference signals are
sampled on alternate lines at half the luminance rate.
Digital video coding method in which the color difference signals are
sampled on all lines at half the luminance rate.
422 Profile at Main Level: A subset of the MPEG-2 standard, which
supports digital video storage (DVD etc.) and transmissions up to 50
Mbps over various mediums. Used for Contribution and Distribution
applications.
8-bit data mapped to 10-bit symbols.
Adaptive Bit Rate.
Adaptive Differential Pulse Code Modulation: An advanced PCM
technique that converts analogue sound into digital data and vice
versa. Instead of coding an absolute measurement at each sample
point, it codes the difference between samples and can dynamically
switch the coding scale to compensate for variations in amplitude
and frequency.
