GOP pattern
(Group of Pictures pattern) A pattern in MPEG
encoding made up of groups of pictures (consisting of
I-, B-, and P-frames), which have certain dependent
relationships during encoding. Changes to this
pattern can cause playback errors in some players.
hold time
Used to describe the time a moving effect (PiP or title
effect) remains stationary on the screen.
HQ
(High Quality) The highest video quality you may
select in PowerDirector.
hue
The attribute of a color that distinguishes it from
other colors.
interlacing
Flickering or artefacts caused by the way video
signals are broadcast. (Each frame of video is made
up of a number of lines. When video frames are
broadcast, the odd lines of the screen display are
illuminated first, then the even lines. This causes the
interlacing problem, which is most evident when the
video contains motion.)
key frame
A key frame is defined as a frame in a video sequence
that does not require information from a previous
frame for decompression. More key frames yield
better video quality but require greater amounts of
disk space.
LP
(Long Play) The lowest video quality you may select
in PowerDirector.
menu
A page on a DVD that contains links to the chapters
the DVD contains.
MiniDVD
A variation of DVD, in which a true DVD (including
menus and high-resolution video) is placed on a disc
in CD-R/W format. while technically a DVD in terms
of data structure, miniDVD is not supported by most
DVD players because the format is mistakenly
recognized as standard CD media. MiniDVD is
playable on a PC with DVD playback software, but
on very few stand-alone DVD players.
