another system (TV, Stereo, etc.).
Bit rate: The amount of data used to hold a
given length of music; measured in kilobits per
second, or kbps. Or, the speed at which you
record. Generally, the higher the bit rate, or the
higher the recording speed, the better the sound
quality. However, higher bit rates use more space
on a disc.

to be transported over the internet, while
maintaining high visual quality.

specifi cally to take full advantage of Pro Logic II
playback, including separate left and right surround

audio. It delivers perfect picture and sound
quality, completely free from noise. HDMI is
fully backward-compatible with DVI.
As required by the HDMI standard,
connecting to HDMI or DVI products
without HDCP (High-bandwidth Digital
Content Protection) will result in no Video
or Audio output.
HDCP (High-bandwidth Digital Content
Protection) is a specifi cation that provides a
secure transmission of digital contents
between different devices (to prevent
unauthorised copyright).
JPEG: A very common digital still picture format.
A still picture data compression system proposed
by the Joint Photographic Expert Group, which
features small decrease in image quality in spite of
its high compression ratio.
MP3: A fi le format with a sound data compression
