Progressive format
(sequential scanning)
In contrast to the Interlace format, the
progressive format can reproduce 50 - 60 frames
per second by reproducing all scanning lines
(525 lines for the NTSC system). The overall
picture quality increases and still images, text
and horizontal lines appear sharper. This format
is compatible with the 525 or 625 progressive
format.

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-
RT lO/EZW-TlOO.
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.
Super Audio CD
Super Audio CD is a new high-quality audio
disc standard where music is recorded in the
DSD (Direct Stream Digital) format
(conventional CD is recorded in the PCM
format). The DSD format, using a sampling
frequency 64 times higher than that of a
conventional CD, and with I-bit quantization,
achieves both a wide frequency range and a wide
dynamic range across the audible frequency
range, and so provides music reproduction
extremely faithful to the original sound.
