CODEC (EnCOder/DECoder)
A method in which a video is encoded for recording or saving to disk then decoded
for playback.
Disc-At-Once
Method in which the laser in your recorder burns straight through in one session
without turning off and on between each track. This method is best when recording
audio CD’s you would like to play in your home or car stereo.
Disc Image
This process can be used when having system performance problems or when you
do not have a burner available. When choosing the disc image option, it takes the
file you want to copy and places it temporarily on your hard disk. From that image it
builds the file. When creating a disc image, you will need a certain amount of drive
space to perform this function.
DV
An acronym for Digital Video, it is the format for storing and saving video and audio
intended for DV products such as cameras and video cameras.
DVD
An acronym for Digital Versatile or Video Disc.
DVD-R
DVD was originally only known for being specific to the movie and gaming market,
you can now burn data and your own home videos to a DVD disc that can be
played by all DVD-ROMs. You have the advantage of storing much more data on
this disc than that of a regular CD-R/RW. The DVD-R is a non rewritable format
that is compatible with most DVD-ROM drives and DVD players.
DVD+RW
A rewritable format developed in cooperation by Hewlett-Packard, Mitsubishi
Chemical, Philips, Ricoh, Sony and Yamaha. It is a rewritable format that provides
full, non-cartridge, compatibility with existing DVD-Video players and DVD-ROM
drives for both real-time video recording and random data recording for many PC
and entertainment software applications.
DVD-RW
An acronym for DVD ReWriteable. The DVD-RW disc is rewritable and performs
the same function as that of a DVD-R. However, the compatibility with various
DVD-ROMs and DVD players is less. Please check with the manufacturer for
compatibility issues.
Frame
A sector is made up of 98 frames. A frame contains 24 data bytes and 9 control
bytes. With an Audio-CD, 75 sectors provide one second of played music.
