This section provides you with a brief explanation of terms, technology and
abbreviations used or referred to in this User’s Guide.
DRM Digital Rights Management (DRM) is a technology which enables the copyright
owner of intellectual property, like a digital audio track, to control how you, the
listener, can use the file. It is normally used to allow you to download digital audio
tracks while preventing you from distributing the files to other people or other
devices. With DRM, digital audio tracks contain digital signatures.
Li-Ion Polymer Lithium-Ion (Li-Ion) batteries are ideal for portable devices like your player. Your
player uses an updated form of the Li-Ion battery, the Li-Ion Polymer battery. This
type of battery has significant advantages over the older Li-Ion battery.
Li-Ion Polymer batteries can be thinner, and safer than the standard liquid
electrolyte Li-Ion battery. They come in more diverse shapes, and use a dry
polymer electrolyte that is more resistant to overcharging and virtually eliminates
the danger of flammability.
NTSC This is short for National Television System Committee, and is commonly used in
the United States of America and Japan. The NTSC standard delivers 525 lines of
resolution at 60 half-frames per second. Your computer’s video adapter may
support both NTSC and PAL signals.
PAL This is short for Phase Alternating Line, and is commonly used in Europe and some
countries in South East Asia. Unlike the NTSC standard used in the United States
of America, PAL delivers 625 lines at 50 half-frames per second. Your computer’s
video adapter may support both NTSC and PAL signals.
