x Interlace
A scanning method which completes a picture
by displaying half of the lines on a tube surface
of a TV or monitor each 1/60 second. First, all
the odd-numbered lines are drawn, leaving
spaces between each line, then all the even-
numbered lines are drawn to fill the spaces.
“i” of “480i” stands for “Interlace.”

x LFE (Low Frequency Effects)
Sound effects of low frequencies which are
output from a subwoofer in Dolby Digital or
DTS, etc. By adding a deep bass with a
frequency between 20 to 120 Hz, audio
becomes more powerful.

x Neural-THX
Neural-THX
®
Surround is taking surround
sound to the next level. This revolutionary new
technology delivers the rich envelopment and
discrete image detail of surround sound in a
format that is fully compatible with stereo.
Neural-THX Surround reduces the bandwidth
needed for broadcasters to deliver true, multi-
channel surround presentations, and enables
7.1-channel support for gaming and movies.
By unmasking the audio details, typically lost
by other playback systems, audiences will
experience the deep ambience and subtle
details of movies, music and games. And with
this technology being used by sound designers
during content creation, as well as embedded
into playback devices, Neural-THX Surround
promises a listening experience that is true to
the original mix.
Neural-THX Surround has been chosen as the
official surround sound broadcast format for
XM Satellite Radio’s “XM HD Surround”, as
well as other leading FM/HD radio stations
worldwide.

x PCM (Pulse Code Modulation)
A method of converting analog audio to digital
audio for easy enjoyment of digital sound.

x Progressive
A scanning method that draws all scanning
lines sequentially, as opposed to interlaced
scanning where all the odd and then all the
even lines are drawn.
“p” of “480p” stands for “Progressive.”

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.

x TSP (Time Stretched Pulse)
A TSP signal is a highly precise measuring
signal that utilizes impulse energy, measuring
a wide band, from low to high, in a short
period.
The amount of energy used to measure signals
is important to ensure measurement accuracy
in a normal indoor environment. Using TSP
signals makes it possible to measure signals
effectively.

x x.v.Color
x.v.Color is a more familiar term for the
xvYCC standard proposed by Sony, and is a
trademark of Sony. xvYCC is an international
standard for color space in video.
This standard can express a wider color range
than the currently used broadcast standard.
