Abstract
Disclosed are a navigation system and/or a point information display method and a program. The navigation system consists mainly of: a stream receiver that receives broadcast streams; a data decoder that samples a data signal from the received streams and decodes the data signal into character string information; a matching block that performs matching to compare a predetermined keyword, which is associated with position information specified in map information data, with stored keywords and searches a keyword consistent with the keyword contained in the character string information; a position information searching block that searches position information associated with the keyword contained in the character string information and detected to be consistent with a stored keyword by the matching block; and a display unit that displays the detected position information while superimposing it on a display image.
