Glossary

clip cache

XFS ﬁlesystems in which the SGI Media Server stores clips. The clip cache can reside on

a normal XFS ﬁlesystem that can be shared with other uses, or a real-time ﬁlesystem

created on a set of striped disks or RAID units.

cue point

Timecodes that are used to move around within a clip and to control the portion of the

clip that is played. An in point, the duration, and an out point are each speciﬁed using

the hh:mm:ss:ff format, where hh is the hours, mm is the minutes, ss is the seconds, and ff

is the frame number. In drop-frame mode, the ﬁnal colon is replaced by a period

(hh:mm:ss.ff).

For example, if a clip with a cue in point of 00:00:30.00 is cued for playing in the forward

direction, it is cued at 30 seconds.

Diaquest

DIF

The compression format used by DVCPRO 25, DVCPRO 50, DVCAM, and DV

by one of these formats.

DSO

ﬁxed media compression.

DVCPRO

A digital video compression format provided by Panasonic. The DVCPRO 25 and

DVCPRO 50 formats provide ﬁxed media compression.

edit point

Persistent timecode values that are stored with a clip. Edit points are used to

automatically initialize the cue points when the clip is loaded. An in point, the duration,

and an out point can each be speciﬁed using the hh:mm:ss:ff format, where hh is the hours,

mm is the minutes, ss is the seconds, and ff is the frame number. In drop-frame mode, the

ﬁnal colon is replaced by a period (hh:mm:ss.ff).
