AYRE DX-5DSD - Manual (Page 121)

DSD Direct Stream Digital is the name for a Pulse
Demsity Modulation (PDM) digital encoding
scheme.
DTS A Compressed Audio format developed by Digital
Theater Systems. A DTS soundtrack is found on
some DVDs, and in generally considered to sound
better than the Dolby Digital soundtrack, in part
due to the higher data rates used. For higher quality
audio on Blu-ray discs DTS has developed DTS-HD
Master Audio, a Lossless Audio compression format.
DVI The Digital Visual Interface was developed as a way
to send digital video signals to a Fixed-Pixel (i.e.,
digital) display without any additional conversions
to or from analog.
Fixed Pixel In a CRT video display the cathode ray, or beam,
can be focused at any arbitrary point on the viewing
surface. Thus multiple Resolutions are easily
supported. In contrast, Fixed Pixel (i.e., digital)
displays have the individual Pixels in predetermined
locations. Incoming signals must be converted to
the native resolution of the display element itself.
This conversion process, called Scaling, can
introduce visible artifacts if not performed at a high
performance level. All fixed pixel displays have
internal scalers incorporated internally.
HDMI The High Definition Multimedia Interface is an
extension of the DVI interface that adds HDCP,
digital audio, and an inter-device communication
link, all in a smaller connector.
