Personal Digital Radio Service

      Disclosed is a system for delivering personalized digital radio
information to a system subscriber, who selects a set of digitally
encoded audio information to be delivered while he is in a vehicle.
With this system, a service uses two Radio Frequency (RF)
transmission paths to deliver information, in quantities limited by
the available bandwidth.

      The Figure is a block diagram showing major parts of the
system.  A radio server 1 is a computer system providing various
functions necessary to operate a personal digital radio service.  RF
transmit ters 2 provide means for radio server 1 to transmit digital
information over a first wireless transmission path 2 to the vehicle
4 of the subscriber.  RF receivers 5 provide means for radio server 1
to receive digital information over a second wireless transmission
path 6.  Radio server 1 interfaces with a user database 7, an
information database 8, and a network interface 9.  The user database
7 contains profile information on the user, including preferred audio
sources and information relative to the location, billing, and credit
of a particular subscriber.  The information database 8 contains
local- content information that is available for transmission to
subscribers.  Network interface 9 is used by the radio server 1 to
access remote information sources which are not part of the service
environment.

      The subscriber accesses radio server 1, for example, through an
Internet connection with network interface 9, to program his
information database 8.  Alternately, the subscriber may contact an
operator/administrator having direct access to radio server 1 for
this purpose.  A subscriber in his vehicle 4 can contact radio server
1 through second wireless transmission path 6 for this purpose.
Contact with radio server 1 may be established with...
