music data to about 1/10th its original size, with very little negative effect on sound quality.
MPEG
A technology that efficiently compresses digital video data. MPEG2 is one of this technology
with outstanding image quality and is used in DVD-Video and other media. Another related

quality or high compression rates through telephone lines and other lines with low
communication speeds.
