Apple is thinking bigger than wireless headphones
they may not use bluetooth though (The means of communication are not very specific and don’t really rule out much: “FM, RF, Bluetooth, 802.11, UWB, IR and magnetic links”)... Here’s an excerpt from the Apple wireless iPod patent application that tells the story of the first, second, third and forth skier and their personal transmitting station:
[0115] In this particular illustration, a first skier 506 holds the personal transmitting station 500 while second, third and fourth skiers 508, 510 and 512 each hold personal tuning devices 502… The first skier 506 is located on a first hill 514, the second and third skiers 508 and 510 are located on a ski lift 516, and the fourth skier 502 is skiing down a second hill 518. As should be appreciated, all of these locations are within the broadcasting or networking range of the personal transmitting station 500.
[0116] The personal transmitting station 500 is configured to send a music signal to the personal tuning devices 502 held by the second, third and fourth skiers 508, 510 and 512 and the personal tuning devices 502 are configured to receive the music signal sent from the personal transmitting station 500. The first skier 506 can therefore effect changes to what is being listened to by the second, third and fourth skiers 508, 510 and 512 by simply selecting a different song to be played on the personal transmitting station 500 (even though he is in a different location than the rest of the skiers). For example, the first skier 506 may end a first song and select a second song to be played therefore causing the personal transmitting station 500 to send the second song to the personal tuning devices 502.
cool... but what are these patent writers on!
