MP3/WMA/JPEG/MPEG playing order
When selected for play, Folder Search, File Search, or for Folder
Select, files and folders are accessed in the order in which they
were written by the CD/DVD writer.
Because of this, the order in which they are expected to be
played may not match the order in which they are actually
played. You may be able to set the order in which MP3/WMA/
JPEG/MPEG are to be played by writing them onto a medium
such as a CD-R with their file names beginning with play
sequence numbers such as "01" to "99", depending on your
CD/DVD writer.
JPEG
JPEG is a standardized image compression mecha-
nism. JPEG stands for Joint Photographic Experts
Group, the original name of the committee that
wrote the standard. JPEG is designed for compress-
ing either full color or gray scale images.
MPEG 1
The most common implementations of the MPEG
1 standard provide a video resolution of 352-by-
240 at 30 frames per second (fps). This produces
video quality slightly below the quality of conven-
tional VCR videos.
MPEG 2
MPEG 2 offers resolutions of 720x480 and
1280x720 at 60 fps (NTSC), with full CD-quality
audio. This is sufficient for all the major TV stan-
dards, including NTSC, and even PAL. MPEG 2 is
used by DVD-ROMs. MPEG-2 can compress a 2-
hour video into a few gigabytes.
