Digital Infrared Audio Transmission
Recent times have been witness to the rapid
spread of DVDs, Digital Broadcasting Satellite
Receiver and other high-quality media. In order
to ensure that the subtle nuances endowed by
these high-quality media would be transmitted
with no accompanying deterioration, Sony
developed a technology called “Digital Infrared
Audio Transmission” for the infrared
transmission of digital audio signals using no
compression, and it introduced it into the DAV-
SB500W.
This technology transfers digital audio signals
using no compression inside the subcarrier
frequency band allocated by the IEC
(International Electronic Committee) and
JEITA (Japan Electronics and Information
Technology Industries Association) for hi-fi
audio transmission applications. (See Fig. 1)
