1080p vs 1080i
Can you tell the difference between 1080i and 1080p? The difference in the way the picture is scanned and displayed on your HDTV set. The i is for interlaced and the p is for progressive.

HDMI 1.3
Increases its single-link bandwidth from 165MHz
(4.95 gigabits per second) to 340 MHz (10.2 Gbps) to
support the demands of future high definition display
devices, such as higher resolutions, Deep Color™ and
high frame rates. In addition, built into the HDMI 1.3
specification is the technical foundation that will let
future versions of HDMI reach significantly higher
speeds. HDMI Learn More
DTS Digital Surround
The basic DTS 5.1 channel sound format. Uses a higher
data rate than Dolby Digital.
DTS 96/24
Delivers 96kHz/24-bit high resolution audio for
5.1-channel/6.1-channel surround sound on DVD discs. The
benefits are greater bit depths for extended dynamic
range and high sampling rates for wider frequency
response.
DTS Neo:6
Provides 5.1 or 6.1 channels of matrix decoding from
stereo matrix material. Also decodes Extended Surround
matrix sound tracks and has a Music mode to expand
stereo non-matrix recordings to 5.1 or 6.1 channels.
DTS-ES Discrete 6.1
In this format, the back surround channel is matrix
encoded into the left and right surround channels. For
playback, the three channels are separately decoded.
DTS Digital Out
DVD player equipped with dts surround optical-digital
and coaxial-digital output.
Dolby Digital
The most popular 5.1-channel home theater sound system.
An improvement over Dolby Pro-Logic in that it offers:
1) Full frequency response in all channels (3Hz —
20kHz), 2) discrete surround channels, and 3) a separate
track for bass only, called the Low Frequency Effects
channel.
Dolby Pro Logic II
Improved version of Dolby Pro-Logic for music and
movies. With a more intelligent matrix decoder, it is
suitable for both stereo and surround-encoded sources.
It offers “bass management” as well as the option of
incorporating “width,” “dimension” and “panorama”
controls.
Dolby Digital EX
This surround format from Dolby Digital includes an
added center rear channel. The rear center channel is
actually matrixed into the two rear channels, and is
extracted upon playback. (Formerly called Dolby Digital
Surround EX, or Dolby Digital Matrix 6.1.)
Dolby Pro Logic IIx
Dolby Pro Logic IIx is an extension of Dolby Pro Logic
II. This algorithm processes native stereo and
5.1-channel content to produce 6.1 or 7.1 output
channels. Dolby Pro Logic IIx expands choice in playback
system configuration (allowing 5.1, 6.1 or 7.1 playback
channels) and, when incorporated into an A/V amplifier
or receiver, allows a convenient upgrade path from a
traditional 5.1-channel sound system to 7.1 output
channels.
THX Ultra2
Created by Lucasfilm, THX is a certification standard
designed to determine the audio components and acoustics
needed to accomplish the most accurate movie audio play
back. For full effect in a home theater, the THX
decoding process requires a 7.1 speaker configuration
with two back-surround speakers.
THX Ultra2 Certified Products are engineered and
designed for large home theaters. Viewing distance of
approximately 12 feet / 4 meters from the display to the
listening position.
THX Select2
Created by Lucasfilm, THX is a certification standard
designed to determine the audio components and acoustics
needed to accomplish the most accurate movie audio play
back. For full effect in a home theater, the THX
decoding process requires a 7.1 speaker configuration
with two back-surround speakers.
THX Select2 Certified Products are engineered and
designed for small to medium sized home theaters.
Viewing distance of approximately 10 feet / 3 meters
from the display to the listening position.
THX Select
Created by Lucasfilm, THX is a certification
standard designed to determine the audio components and
acoustics needed to accomplish the most accurate movie
audio play back. For full effect in a home theater, the
THX decoding process requires a 7.1 speaker
configuration with two back-surround speakers.
THX Select Certified Products are engineered and
designed for superior performance and complement the
presentation of THX Select2 Certified Receivers.
SRS Circle Surround II
Circle Surround II is an advanced surround sound decoder
that enables up to 6 channels of surround sound from
surround encoded (Lt/Rt) and Circle Surround encoded
material and is backward compatible with mono, stereo
and most matrix decoders.
Neural Surround
Neural Surround™, a proprietary audio format that embeds
the rich envelopment and discrete image detail of
surround sound and is 100% compatible with stereo
content. Chosen by XM Satellite Radio as the format for
their 24/7 XM HD Surround programming
XM - XM Ready
These receivers are XM SATELLiTE RADiO (XM Ready),
allowing you to hear over 150 digital channels of music,
news, sports, talk and entertainment from America's
number one Satellite Radio service. With the addition of
the XM Connect and Play digital antenna accessory (sold
seperately) just subscribe to XM SATELLiTE RADiO and
hear radio as it was meant to be!
XM HD Surround Sound
XM and Neural Audio Corporation announce XM HD Surround,
which provides content with six discrete channels of
digital full fidelity audio powered by Neural Audio
technology. Marking the first time that a radio company
has broadcast in 5.1 Surround Sound twenty-four hours a
day. Beginning in April 2006, XM will broadcast the Fine
Tuning® (XM Channel 76) and the classical pops music
channel XM Pops (XM Channel 113) in XM HD Surround. XM
will also broadcast a variety of special shows and live
music performances at the XM studios in XM HD Surround.
Made for iPod
The optional YDS-10 Universal Dock lets you connect your
iPod to this receiver. You can listen to your iPod music
and watch iPod images and movies on your monitor via the
receiver. You can also operate your iPod via the
receiver’s remote unit with the On-Screen Display and
charge your iPod. Works with:iPod nano, iPod mini and
iPod (Click and Wheel)
i-Link
i.LINK provides a digital connection for DVD-Audio
Linear PCM, Super Audio CD DSD (Direct Stream Digital)
and other high quality audio sources.
HD Radio
HD Radio, the only digital broadcast system in America
approved by the FCC, offers you crystal-clear,
CD-quality sound via existing AM/FM radio bands. In
addition, it gives you program-associated data and the
ability to tune to multiple programs at the same dial
position. Over 2,500 radio stations are in the fast lane
upgrading to HD Radio broadcasting to reach 95% of
America's population, and more than 230 stations are
onair now.
MP3
Short for MPEG-1 layer 3 audio, MP3 is a compression
process used to shrink audio files by filtering out all
noise that is not detectable to the human ear. MP3 is
considered near CD-quality, but the file itself occupies
approximately one tenth to one twelfth the space of the
original CD format, making it the perfect medium for
today’s smaller, memory based portable media players.
DivX
DivX is the video compression codec developed by DivX
Networks and based on the MPEG-4 compression format. Its
balance of high video quality and low bit rate has made
it very popular and quickly established it as the best
home video format thus far. The ability to play it on
newer DVD models continues to add to its popularity as
DivX Networks advances its support to many new household
products. This compression technology has the potential
for expanding the ways we view video media in much the
way MP3 has given us many new ways to listen to music.
Gracenote
The ability to navigate and organize large music
collections is largely dependent on accurately
identifying and categorizing songs, albums and artists
that it contains. Gracenote MusicID™ is the essential
ingredient for digital media recognition of CDs, digital
music files and streaming audio. With the most
comprehensive database of music recordings in the world,
the Gracenote Media Database contains more than 55
million tracks and 4 million CDs.
