Abstract: General electronic program information described on a general level and individual electronic program information described on an individual level are prepared according to electronic program information of a channel service of a broadcast service provider for each channel service according to electronic program information degree of detail setting information. The electronic program information degree of detail setting information indicates a degree of detail for the contents of the individual electronic program information described on an individual level and a degree of detail for contents of the general electronic program information described on a general level. The general level corresponds to a low degree of detail, and the individual level corresponds to a high degree of detail.

Abstract: A program information producing apparatus broadcasts program information of a next program belonging to the same program group as a subjective program in addition to the program information of the subjective program. A broadcast receiving apparatus displays the program information of the next program based on the received program information of the subjective program, thereby allowing a viewer to make a reservation of the next program after checking its content during the user viewing each event of a series of programs.

Abstract: A control information generating apparatus is provided which is used in broadcast systems designed to transmit audio and video signals and/or teletext signals together with video control information and program information in multiplexed form. The control information generating apparatus transmits EPG (Electronic Program Guide) information (i.e., control information) for transmission of the audio and video signals and includes a control information generating circuit and a control information outputting circuit. The control information generating circuit receives program schedule information on a program from a broadcast database to generate and output control information. The control information outputting circuit receives and output the control information to a multiplexer in which the control information and a data signal from an audio/video data transmitter are multiplexed and transmitted on a carrier wave.

Abstract: A program control information generator for realizing functions of high-speed generation and transmission of program control information and of an automatic adjustment of program information without interrupting the generation. In a broadcasting station system for broadcasting program control information, the program control information generator comprises an input section 101, a schedule adjustment section 102, a band adjustment section 103, a storage section 104, a difference detecting section 105, and a section generating section 106 in generating section data from program information and program schedule information inputted from a program organization apparatus, by which it is possible to provide a program control information generator which realizes a high-speed program control information generation and an automatic schedule adjustment method with a schedule overlap or an effective adjustment method of program control information in which a band over may occur.

Abstract: A document storing and managing system for storing plural electronic documents in each of folders according to classifications and managing the stored electronic documents in a unit of the folder has a folder managing means for managing attributes of the electronic documents included in each of the folders, a document version managing means for managing information as to version of the electronic documents included in each of the folder, and a folder version managing means for managing a correspondence relation between a version of the folder and a version of each of the electronic documents included in the folder. The document storing and managing system of this invention may set and manage a version of a folder while keeping adjustability with a version of each document.
