Abstract

An information receiving apparatus is disclosed, which comprises: storing means for storing pairs of area information assigned for predetermined areas and area name thereof; area information detecting means for detecting area information contained in received information; area name detecting means for detecting an area name of the current position of the apparatus corresponding to the detected area information with reference to the storing means; searching means for searching for a message element for the area name of the current position of the apparatus among a message in the received information; and displaying means for displaying the searched message element on a displaying portion.

Claims

1. A location detecting information receiving apparatus comprising:

a relating table for relating plurality of first area information each corresponding to a predetermined area with area names;

area information detecting means for detecting second area information contained in received information;

area name detecting means for detecting an area name of the current position of the apparatus corresponding to the detected second area information based upon a comparison with the plurality of first area information held in said table;

searching means for searching a message portion of said received information for a message element identifying said detected area name of the current position of the apparatus contained in the message portion of said received information; and

displaying means for displaying said message element on a displaying portion.

2. The location detecting information receiving apparatus as set forth in claim 1,

wherein said searching means detects an area name at the current position of the apparatus in said message portion of said received information so as to detect the beginning of said message element corresponding to said detected area name at the current position of the apparatus.

3. The location detecting information receiving apparatus as set forth in claim 2,

wherein said searching means, after detecting the beginning of said message element for the detected area name at the current position of the apparatus, detects any subsequent area name in said message portion of the received information so as to detect the end of said message element corresponding to the detected area name at the current position of the apparatus.

4. The location detecting information receiving apparatus as set forth in claim 3, further comprising:

means for enabling/disabling said searching means and said displaying means.

5. The location detecting information receiving apparatus as set forth in claim 2, further comprising:

means for enabling/disabling said searching means and said displaying means.

6. The location detecting information receiving apparatus as set forth in claim 1, further comprising:

means for enabling/disabling said searching means and said displaying means.

7. A location detecting information receiving apparatus, which comprises:

a table for relating a plurality of area information, each area information being assigned to a predetermined area, and a character code string of each area name corresponding to each area information, the plurality of area information and corresponding character code string being related before a stream of information is received;

area information means for detecting area information contained in the received stream of information;

area name retrieving means for looking up the character code string of the area name of the current position of the apparatus corresponding to the detected area information from said table;

searching means for searching for a message portion coming after the detected area information in said stream of said received information for a character code string identical with the looked up character code string;

extracting means for extracting a message element which follows the searched character code string and is a subset of said message portion; and

displaying means for displaying said extracted message element on a displaying portion.

8. The location detecting information receiving apparatus as set forth in claim 7, wherein said searching means, after the character code string identical with the received character code string has been searched, searches for a character code string of any area name held in said table so as to detect the end of said message element.

9. The location detecting information receiving apparatus as set forth in claim 8, further comprising means for enabling/disabling said searching means and said displaying means.

10. The location detecting information receiving apparatus as set forth in claim 7, further comprising means for enabling/disabling said searching means and said displaying means.
