Digital Audio Broadcasting (DAB) works by broadcasting digital signals within a given radio frequency range [in the uk its 217.5 - 230.0 MHz]
The audio signal is digitally encoded, transmitted and then decoded by a DAB unit.
DAB can also be used to broadcast data and text and its this facility
that I think can be further exploited.
If a transmitting unit can send data which can be received elsewhere, then it is possible to have these two units bond by via a handshake protocol.
Once bonded, these units could then transmit data/music/text.
Why do i propose this? If there was a single digital frequency made available for local broadcasting [over a 100m range for example], we could all use radio to transmit where we currently use IR or FM broadcasting. Applications could be
wireless headphones
speakers around the house
mp3 or portable cd players in cars

Digital radio was invented by Marconi. He just used a very very slow bit rate! |
|
| |
Around here they call it "Wireless" ... as if it was something "New" instead of over 100 years old! (Radio was called "wireless" before it had sound) |

seems like I spark off ideas for you RT. Pleased to help! |

How about using Wi-Fi and
Icecast instead? |
|
| |
What I want is an Rendezvous
capable, wi-fi enabled iPod that
can stream the current output as
Icecast (to whatever's listening)
and share files with other iPods
or Rendezvous-enabled (aka
ZeroConf) computers. If
anyone's at Apple's listening, I
reckon you'd be on to a real
winner... and all I ask for my
thoughts is a test unit ;-) |
