JPEG(Joint Photographic Experts Group) is the most widely used picture compression and
storage format today. Utilizing high efficiency compression algorithm, JPEG compresses
the original picture 15 to 20 times with excellent picture quality. JPEG is featuring small
size data, convenient application and supported by most picture processing software, so
it is very fit to store photos.
The strong decoding capability of this unit can decode and play the files with the above
formats. In the course of playing, an operation menu will appear and its construction is
shown as follows.

MPEG4ANDJPEGFILEPLAYBACK
MPEG4 is the audio standard published by MPEG(Moving Pictures Experts Group) in
November,1998.As the discrepant parts between frames of picture are only processed and
the same parts are deleted, the data number are greatly decreased. The most distinct
feature of MPEG4 is the high compression and clear imaging. Furthermore, MPEG4 provides
elastic specifications to adjust the stream according to the used requirements. The larger
stream can be used when collecting private films; and the small stream can be used in
network transferring, which make MPEG4 use widely.
