Application extension program, information processing apparatus, and method

By describing electrical program guide information in a language such as XML and then multiplexing the electrical program guide information to a broadcast signal for transmission, advertisements, images and sounds can be easily entered and various program guides can be realized. For manufacturers of receiving devices, it suffices to develop only the software for receiving, decoding and displaying received XML data. There is no need to develop the software for displaying the EPG for each type of receiving device. Thus, the number of development steps can be reduced.

Transmission method and receiving device of program guide information including a control signal

A server computer stores user favorites information that relates to the favorites of a user. Whether digital information that has newly occurred on a network suits the favorites of the user is judged based on the user favorites information. If it is judged that there exists digital information that suits the favorites of the user, the server computer informs the user of the new establishment of the digital information that suits the favorites of the user by transmitting E-mail to the user. When a browsing request of the digital information is made by the user, the server computer delivers the digital information to the user and stores history information relating to a history of the digital information that has been delivered to the user. Thereafter, the server computer updates the user favorites information based on the history information.

Intelligent information retrieval system using hierarchically classified preferences

At a server, a subject for updating an object registered in a databaseand an event for obtaining the subject are generated, while a request for the subject from a receiving terminalis received and totaled so that a resource necessary for providing the subject is allocated on the basis of the result of totaling. Then, the event is transmitted and the subject is provided on the basis of the resource allocated thereto. At the receiving terminal, the event is received and the necessity of the subject to be obtained on the basis of the event is evaluated so that request data requesting the subject is transmitted to the serveron the basis of the result of evaluation. Then, the subject provided by the serverin response to the request data is obtained on the basis of the event.

Contents providing device, contents providing method, receiving device, receiving method, communication system, and communication method

A transmitting system for transmitting contents data, meta data, and meta data schema. A meta data schema that represents the structure of meta data of contents data is stored in a meta data schema storing portion. A contents segmenting portion generates segmentation data for selecting a particular segment from successive contents data supplied from a contents storing portion and supplies the generated segmentation data to a meta data combining portion. The meta data combining portion correlates meta data with corresponding segmentation data in a format corresponding to the structure of the meta data schema, combines the meta data with the segmentation data, and outputs the combined data. The meta data schema, meta data with segmentation data, and contents data are converted in a transmission format.
