Dolby Surround (Dolby Pro
Logic)
Audio processing technology developed by
Dolby Laboratories, Inc. Center and mono
surround information is matrixed into two
stereo channels. When reproduced, audio is
decoded and output in 4 channel surround
sound. This is the most common audio
processing method for DVD-video.

DTS 96/24
A high sound quality digital signal format. It
records audio at a sampling frequency and bit
rate of 96kHz/24bit which is the highest
possible for DVD-video. The number of
playback channels varies depending on the
software.

DTS Digital Surround
Digital audio encoding/decoding technology
for theaters developed by DTS, Inc. It

HDMI (High-Definition Multimedia
Interface) is an interface that supports both
video and audio on a single digital connection,
allowing you to enjoy high quality digital
picture and sound. The HDMI specification
supports HDCP (High-bandwidth Digital
Contents Protection), a copy protection
technology that incorporates coding
technology for digital video signals.
x
PCM (Pulse Code Modulation)
A method of converting analog audio to digital
audio for easy enjoyment of digital sound.
x
Sampling frequency
To convert analog audio to digital, analog data
should be quantified. This process is called
sampling, and the number of times per second
the analog data is quantified is called the
sampling frequency. A standard music CD
stores data quantified at 44,100 times per
second, which is expressed as a sampling
frequency of 44.1 kHz. Generally speaking, a
higher sampling frequency means better sound
quality.

xvYCC standard proposed by Sony, and is a
trademark of Sony. xvYCC is an international
standard for colour space in video.
This standard can express a wider colour range
than the currently used broadcast standard.
