Glossary
• Fragmentation
The 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.
There are MPEG 1 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], [LIII INDEX] and [iii 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.
