Abstract
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.
Claims22
An information filtering system, comprising:
- an information filtering unit comprising:
- receiving means for receiving programs broadcast by a broadcasting station;
- filtering means for carrying out rough filtering with respect to the received programs based on an electric program guide broadcast by the broadcasting station, and for instructing video equipment about a wide range of programs;
- analyzing means for analyzing the contents of the programs received by the receiving means;
- selecting means for, by collating the analyses of the analyzing means with a stored profile including personal programming tastes of a user, selecting a program that matches the profile;
- means for sending an instruction to continue program recording to the video equipment in response to the results of selection by the selecting means;
- and
- means for sending an advance instruction for program recording to the video equipment in response to an electric program guide broadcast by the broadcasting station;
- and
- the video equipment for automatically recording a program from the broadcasting station which is selected by the selecting means in the information filtering unit, in response to the instruction to continue program recording, and for erasing the program when the instruction to continue program recording is not sent.
An information filtering system comprising:
- an information filtering unit comprising:
- receiving means for receiving programs broadcast by a broadcasting station;
- filtering means for carrying out rough filtering with respect to the received programs based on an electric program guide broadcast by the broadcasting station, and for instructing video equipment about a wide range of programs;
- analyzing means for analyzing contents of the program;
- output means for outputting a summary of a program received by the receiving means and time information associated with the summary;
- rebroadcasting time detecting means for detecting a program rebroadcasting time from the electric program guide broadcast by the broadcasting station;
- and
- sending means for sending to video equipment the summary and associated time information output from the output means and the rebroadcasting time detected by the rebroadcasting time detecting means, the sending means comprising:
- means for sending an instruction to continue program recording to the video equipment;
- and
- means for sending an advance instruction for program recording to the video equipment in response to the electric program guide broadcast by the broadcasting station;
- and
- the video equipment, responsive to the summary and associated time information and rebroadcasting time sent from the sending means, for displaying the summary, for automatically recording a program in response to the instruction to continue program recording, and for erasing a program when the instruction to continue program recording is not sent by the sending means.
An information filtering unit, comprising:
- receiving means for receiving programs broadcast by a broadcasting station;
- filtering means for carrying out rough filtering with respect to the received programs based on an electric program guide, and for instructing video equipment about a wide range of programs;
- analyzing means for analyzing the contents of the programs received by the receiving means;
- selecting means for, by checking the analyses of the analyzing means with a stored profile including personal programming tastes of a user, selecting a program that matches the profile;
- means for sending an instruction to continue program recording to the video equipment in response to the results of selection by the selecting means;
- and
- means for sending an advance instruction for program recording to the video equipment in response to an electric program guide broadcast by the broadcasting station.
An information filtering unit, comprising:
- receiving means for receiving programs broadcast by a broadcasting station,
- filtering means for carrying out rough filtering with respect to the received programs based on an electric program guide, and for instructing video equipment about a wide range of programs;
- output means for outputting a summary of a program received by the receiving means and time information associated with the summary;
- and
- rebroadcasting time detecting means for detecting a program rebroadcasting time from an electric program guide broadcast by the broadcasting station.
An information filtering method for use with an information filtering unit, connected with television broadcast viewing video equipment by a communications line, for selecting a program from a number of programs comprising the steps of:
- filtering means for carrying out rough filtering with respect to a received program based on an electric program guide, and for instructing video equipment to a wide range of programs;
- analyzing the contents of programs in terms of at least one of video, sound, and text, and extracting associated attributes;
- checking the extracted attributes against a stored profile including personal programming tastes of a user in advance to select a program that matches the profile;
- sending an instruction to continue program recording to the video equipment;
- and
- sending an advance instruction for program recording to the video equipment in response to an electric program guide broadcast by the broadcasting station.
An information filtering method for use with an information filtering unit, connected with video equipment for viewing television broadcasts by a communications line, for selecting a program from a number of programs, comprising:
- carrying out rough filtering with respect to a received program based on an electric program guide, and for instructing video equipment to a wide range of programs;
- creating a summary of a program;
- and
- transmitting the created summary representing time information within the program to the video equipment.
