Digital audio terms
DRM, security
Digital Rights Management (DRM) technologies protect copyright ownership of digital
information. DRM became an issue with the rise of MP3 technology and Internet distribution
of music. DRM platforms serve as a security “wrapper” around digital audio supporting
Internet distribution while at the same time protecting and managing rights related to that
digital information.
The security mechanism in the Rio supports several secure file formats. When you download
a secure track from a CD or the Web to the Rio, you must have the licence associated with
the track. If the Rio does not read a corresponding licence for a track, the tracks themselves
contain information on where you can purchase them. Publishers can program restrictions on
how many times you can play, copy, or distribute a song directly into the music files. Although
the Rio includes security, it is still able to accept and play standard MP3 files.
Encoding, or Ripping (a CD)
Encoding, or “ripping”, refers to converting an audio file from an audio CD into a compressed
digital audio format, such as MP3 or WMA, that may be played on the Rio or a computer.
Firmware
Firmware is software–programmes or data–that has been written to read-only memory
(ROM). Firmware is a combination of software and hardware that is comparable to an
operating system on a computer. The Rio firmware controls everything from the liquid crystal
display and codec support to the Rio’s many other functions.
To view your Rio’s firmware version:
1 Press the Menu button.
2 Press the
<<
or

(Forward or Reverse) joypad buttons to navigate to About.
3 Press Select (Centre joypad button). The firmware version the Rio is using is displayed.

Gracenote
Gracenote, formerly known as the CD Database (CDDB), is a vast database of CD
information that includes artist, disc name, song title, and other information. Gracenote
supports hundreds of third-party software CD players. Software programmes use CD serial
numbers to search the Gracenote Web site for CD information. Access to the Gracenote
service is offered free of charge to end-users. Visit the Gracenote Web site
for
