x S-AIR
(Sony Audio Interactive Radio
frequency)
Recent times have seen the rapid spread of
DVD media, Digital Broadcasting, and other
high quality media.
To ensure that the subtle nuances of these high
quality media are transmitted with no
deterioration, Sony has developed a
technology called “S-AIR” for the radio
transmission of digital audio signals with no
compression, and has incorporated this
technology into the EZW-RT10/EZW-T100.
This technology transfers digital audio signals
with no compression using the 2.4 GHz band
range of ISM band (Industrial, Scientific, and
Medical band), such as wireless LANs and
Bluetooth applications.
x S-Master
S-Master is an all-digital amplifier technology
developed by Sony, which effectively
minimizes the occurrence of sound
fragmentation and jitter, delivering superb
dialog clarity and faithful reproduction of the
original sound. The compact amplifier section
supports a higher power efficiency and
improved thermal performance.
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.Colour
“x.v.Colour” enables the more faithful
reproduction of various colours such as the
brilliant colours of flowers and the turquoise
blue of the southern ocean.
“x.v.Colour” is a promotion name given to the
products that have the capability to realize a
wide colour space based on the xvYCC
specifications and is a trademark of Sony
Corporation.
xvYCC is an international standard of the
technical specifications of the extended-gamut
colour space for video signals. The colour
gamut of xvYCC is wider than the one of
sRGB that is used with the current television
system.
