Glossary

interlaced

A graphics system in which the even scanlines are refreshed in one

 

vertical cycle (field), and the odd scanlines are refreshed in another

 

vertical cycle. The advantage is that the video bandwidth is roughly

 

half that required for a non-interlaced system of the same resolution.

 

This results in less costly hardware. It also may make it possible to

 

display a resolution that would otherwise be impossible on given

 

hardware. The disadvantage of an interlaced system is flicker,

 

especially when displaying objects that are only a few scanlines

 

high.

IQ Signals

Similar to the color difference signals (R-Y), (B-Y) but using

 

different vector axis for encoding or decoding. Used by some USA

 

TV and IC manufacturers for color decoding.

ISA (bus)

Industry Standard Architecture (bus). The de facto standard system

 

bus for IBM-compatible computers until the introduction of VESA

 

and PCI. Used in the reference platform specification. (IBM)

ISASIO

ISA Super Input/Output device

ISDN

Integrated Services Digital Network. A standard for digitally

 

transmitting video, audio, and electronic data over public phone

 

networks.

LAN

Local Area Network

LED

Light-Emitting Diode

LFM

Linear Feet per Minute

little-endian

A byte-ordering method in memory where the address n of a word

 

corresponds to the least significant byte. In an addressed memory

 

word, the bytes are ordered (left to right) 3, 2, 1, 0, with 3 being the

 

most significant byte.
