GLOSSARY
ASF Short for Advanced Streaming Format, a streaming multimedia
file format developed by Microsoft for Windows 98. Term is
currently used interchangeably with WMA and WMV.
bitrate Bitrate denotes the average number of bits that one second of
video/audio data will consume.
CD-R & CD-
RW
CD-R stands for "CD-Recordable". Recordable CDs are WORM
(Write Once, Read Multiple) media that work just like standard
CDs but may only be written to once unlike CD-Rewritable (CD-
RW) discs, which may be reused. However, its main disadvantage
is that it doesn't work in all players. CD-Rewritable drives are able
to write both CD-R and CD-RW discs and all CD recorders can
read CDs and CD-ROMs. Volume, of 650 MB, is just like any other
CD-ROM disc.
chapter For DVDs, chapters make up one title. There are roughly 20+
chapters for the entire length of one DVD movie.
codec Short for video COmpression and DECompression. Each codec
uses a different algorithm to compress and decompress video
data. Without codecs, storing and playing back digital video
would be impractical. Common codecs include Indeo, Cinepak,
RLE, MS Video 1, and MPEG.
deinterlace Deinterlaces interlaced video content, especially from TV signals
and is mainly used to display interlaced video programs on non-
interlaced computer monitors (see "interlaced video content" on
page 147 for more information).
DivX A digital video codec that uses MPEG-4 technology. This file
format compresses high-quality video to a small enough size that
makes sending video over the Internet a realistic option for many
users.
DSL See xDSL.
