Abstract
In an on-demand type radio transmitting/receiving apparatus, a commercial program stores commercial broadcasting information. A commercial broadcasting device always continuously periodically broadcasts a plurality of commercial programs as a unit. A taste storage device stores a type of information desired by the user. A time storage device holds the latest current time. A position storage device holds the latest position information. An address & longitude/latitude correspondence device incorporates a correspondence table of a normal address and longitude/latitude information and, upon receiving an address as an input, outputs corresponding longitude/latitude information. Upon receiving the commercial program, a commercial program selector compares the classification information, time information, and longitude/latitude information in the commercial program with values in the taste storage device, time storage device, and position storage device, and selects and outputs only a matching commercial program. A reproducer reproduces the content of the commercial program output from the commercial program selector. An on-demand type radio transmitting/receiving method is also disclosed.
