In an information filtering unit connected with user's video equipment by a communications line, a program content analyzing section analyzes the contents of broadcast programs from a broadcasting station in terms of substantial information such as video and sound. A collation evaluation section evaluates the similarity between the analyses and a user's profile stored in a profile storage section. A program selecting selection transmits the result of program selection to the video equipment in the form of time information. The video equipment receives and records a program from the broadcasting station in accordance with the time information sent from the information filtering unit. |

DETAILED DESCRIPTION OF THE INVENTION A first embodiment of the present invention will be described first.
In FIG.
1, there is shown a relationship among a broadcasting station system, an information filtering unit, and video equipment, which create an operating environment of the first embodiment.
Various programs and an electric program guide are broadcast from a broadcasting station 1.
The information filtering unit 2 receives the programs and the electric program guide and, on the contents thereof, performs processes such as of making a search (for example, when a keyword is registered, searching for a scene associated with that keyword), making a selection, associating (for example, associating a keyword with a video portion that is associated with that key word), and structuring (for example, in the case of news, segmenting it into topics).
The analyses by the information filtering unit 2 are delivered to the video equipment 4 on the user side.
Upon receipt of the analyses thus delivered, the user's video equipment performs a function of recording automatically a broadcast directly received from the broadcasting station 1 or displaying a program summary to the user.
In addition, the video equipment has a function of an information terminal for registering in the information filtering unit 2 information that what kind of program the user prefers.
Further, the video equipment produces viewing information representing which programs the user viewed from operations he or she performed on the video equipment and sends it to the information filtering unit 2 as feedback information indicating user's personal tastes.
The information filing unit 2 makes program selection on the basis of a profile 3 consisting of previously registered information concerning programs for which the user has his or her personal tastes and feedback information gathered through actual program viewing.
The method of communications between the information filtering unit 2 and the video equipment 4 is not particularly limited
