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)
