processors. Through the use of tar-
geted compression of audio mate-

increase without actually increas-
ing the audio level.
MB
àMEGABYTE
Megabyte
Unit of measure for data quantities.
According to the traditional defini-
tion of 1
àBYTE is 210 x210, then 1
MB comprises 1,024 x 1,024 bytes
= 1,048,576 bytes. Recently, some
of the manufacturers have stopped
using this traditional binary calcu-
lation method, and are using the
decimal system instead. According
to this version, one megabyte cor-
responds to 1,000,000 bytes.
To display a full uncompressed
frame with full resolution in accor-
dance with ITU-R 601, graphics
data of slightly less than 1 MB are
required (830 KB).
Megahertz
A àFREQUENCY of one million
oscillations (samples) per second.

els in one and the same Project.
This is important if the material
was digitized in various resolutions
in order to save fixed disk capacity.
M-JPEG

sion process which is based on
