Radio information bulletin board

摘要

A radio information bulletin board includes an information transmitter and receiver. Receiving from a portable radio information terminal a request for transmitting stored display information, the information transmitter and receiver reads the display information from a display information storage element, and transmits by radio the display information that is read to the portable radio information terminal originating the transmission request. The portable radio information terminal acquires the display information on the radio information bulletin board in a more useful and precise manner than when taking notes of the displayed information or when memorizing the displayed information while watching the display information.
