In a program information broadcasting system, it is aimed to minimize time for retrieval of program by viewers in operating an electronic program guide or time for waiting when applying for subscription. As a program information broadcasting system, program elements constituting a broadcasting program are divided into a plurality of items and are turned to data at a center, and a master dataof a program information to recognize the program is prepared. From the data constituting the master data, minimal necessary items for preparation of a program table are extracted, and a program basic informationis prepared. Said master data and said program basic information are transmitted simultaneously with the broadcasting, and said program basic information is received, reproduced and displayed before receiving of the master data at a receiving terminal unitis completed. As a result, the program basic information having far less amount of data than the master data can be incorporated, and it is possible to minimize the time required for storage of the data in memory of the receiving terminal unit.

A dynamic area search device includes: a search condition obtainment unit that obtains information on search objects and a condition for a search scope for searching for the search objects; an on-map operation detection unit that detects a first user-specified point on a map displayed on a display; a content search unit that searches for elements associated with locations on the map, based on the information on the search objects; a display area determination unit that determines a first area that has the user-specified point at the center, and includes, among the elements searched for by the content search unit, elements that meet the condition for the search scope; and an area boundary display unit configured to dynamically display, on the map, the user-specified point and the first area determined by the display area determination unit.

A content managing apparatus includes: an obtaining unit which obtains (i) a first content item held by a first user, (ii) a metadata item that indicates attribute information for classifying the first content item, and (iii) information on a sharing state, between the first user and a second user who is a user other than the first user, of a second content item having a metadata item identical to the metadata item held by the first content item; a degree of interest calculating unit which calculates a degree of interest that is an index indicating an interest of the second user on the metadata item; and a managing unit which manages the first content item based on the degree of interest of the second user.

A device stores therein contents and time information pieces each indicating time at which the corresponding content was generated; categorizes, into first and second groups, objects included in contents corresponding to time information pieces indicating times within a first period and a second period that partially overlap, the first group composed of objects that are included in contents corresponding to time information pieces indicating times within the first period and are similar to each other, and the second group composed of objects that are included in contents corresponding to time information pieces indicating times within the second period and are similar to each other; and when a number of objects belonging to both the first and second groups is greater than or equal to a predetermined number, associates the objects belonging to the first group with the objects belonging to the second group as objects indicating a same entity.

When registering content in a data storage unit (), a data registration unit () transmits, to another content management apparatus, metadata that is assigned to the content. The content management apparatus which has received the metadata returns related metadata that is related to the received metadata. An import determination unit () determines whether or not each of the metadata elements included in the returned related metadata is importable. The metadata elements which have been determined to be importable, within the related metadata, are added by a metadata editing unitas a part of the metadata of the content that is to be registered.
