Glossary
Fragmentation
°e condition of a media in which files are
divided into pieces scattered around the media.
You may not save your images correctly. You
can solve the condition by performing [MEDIA
FORMAT] (p. 52).
JPEG
JPEG stands for Joint Photographic Experts
Group, a still image data compression (data
capacity reduction) standard. Your camcorder
records still images in JPEG format.
MPEG
MPEG stands for Moving Picture Experts Group,
the group of standards for the coding (image
compression) of video (movie) and audio.
°ere are MPEG1 and MPEG2 formats. Your
camcorder records movies with SD (standard
definition) image quality in MPEG2 format.
Thumbnail
Reduced-size images which enable you to
view many images at the same time. [VISUAL
INDEX], [
INDEX] and [
INDEX] use a
thumbnail display system.
VBR
VBR stands for Variable Bit Rate, the recording
format for automatically controlling the bit rate
(the volume of recording data in a given time
segment) according to the scene being recorded.
For fast-moving video, a lot of hard disk space is
used to produce a clear image, so the recording
time to the media shortens.
