1. A content distribution apparatus comprising:
- a meta-information content collecting section that collects meta-information content from a server that has location-dependent content, which is content assigned correspondence to geographical location information, and the meta-information content including geographical location information indicating a geographical location of the location-dependent content and network location information that is a link destination of the location-dependent content;
a list content generation section that divides a geographical distribution region of the location-dependent content into mesh-shaped areas based on the geographical location information of the meta-information content, generates a content information block in which the geographical location information is added to content information including the network location information as an index, collects together the content information blocks for each area, generates an area information block in which area location information defining a location and shape of area is added thereto as an index, and generates list content having a structure wherein the area information blocks are listed; and
a list content distribution section that distributes the list content.

5. A content receiving apparatus comprising:
-
a content receiving section that receives list content that has a structure in which are collected together for each geographical area content information blocks to which the geographical location information is added as an index to content information including network location information that is a link destination of location-dependent content that is content assigned correspondence to geographical location information indicating a geographical location, and area information blocks are listed in which area location information defining a location and shape of area has been added as an index thereto;
a location information acquisition section that acquires point location information indicating a current point or search point; and
a content processing section that sets a content geographical search condition based on the point location information, and narrows down the area information blocks subject to searching by comparing the search condition with the area definition information, and furthermore compares the search condition with the geographical location information, thereby generating local region list content comprising a list of the content information that matches the search condition from the list content. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
