MP3 // JJPEG PPicture C CD FFile PPlaying
MP3 utilises the third layer audio compression mode of the international
standard MPEG with the compression ratio 12:1. Employing MP3, one
disc can record 600-minutes music or 170 songs with sound quality
almost as good as CD for everyday listening.
JPEG (Joint Photographic Experts Group) is the most widely used picture
compression and storage format today. Utilising the high efficiency
compression calculating method, JPEG compresses the original picture
15 to 20 times with excellent picture quality.
