Abstract

A reservation recording module registers program information in a reserved program EPG database and a restriction period in a restriction period setting information. A reserved program keyword extracting module extracts an associative keyword from the program information registered in the reserved program EPG database and registers the associative keyword in an associative keyword database. An information content analyzing module extracts a keyword group from the program information about a now-broadcasting program in electronic program guide (EPG) data. An associated information restriction period determining module specifies as a restriction target program, only a not-yet-viewed program satisfying the restriction period in the respective programs registered in the reserved program EPG database. A program related information determining module calculates, for every restriction target program, an association level between the keyword group registered in the associative keyword database and the keyword group extracted by the information content analyzing module. If there exists the restriction target program with the association level being higher than a predetermined threshold value, an alarm issuing module 39 outputs an alarm message on a display.

Claims

1. A broadcast receiving system receiving and recording a broadcasted program in a storage device, comprising:

a reservation module registering a channel and a broadcasting time zone of a program designated by a user in a reserved program database, and setting and storing in a storage device a condition of a restriction period;

a keyword extracting module extracting, for every program of which channel and broadcasting time zone are registered in the reserved program database, a keyword from program contents contained in the program information and registering the keyword in a keyword database;

a display device acquiring information from outside of said system and displaying the acquired information on a screen;

an information analyzing module analyzing a content of the information acquired from outside of said system by said display device and extracting the keyword from the information;

a restriction period determining module determining as a restriction target program, the program, of which the channel and broadcasting time zone are registered in the reserved program database and of which broadcasting time zone is within the restriction period defined under the condition of the restriction period;

an associated information determining module calculating an association level between the keyword registered in said keyword database for the program determined as the restriction target program by said restriction period determining module and the keyword extracted by said information analyzing module, and determining whether or not there is the program with the calculated association level exceeding a predetermined threshold value; and

an alarm issuing module issuing an alarm showing that said associated information determining module determines that there is the program with the association level exceeding the threshold value.

2. A broadcast receiving system according to claim 1, wherein the information acquired from outside of said system is electronic program information on a program now on broadcasting displayed on the screen by said display device.

3. A broadcast receiving system according to claim 1, wherein the information acquired from outside of said system is information acquired via the Internet, and said display device displays a content of the information on the screen.

4. A broadcast receiving system according to claim 3, wherein said information analyzing module further extracts transmission time from the information acquired from outside of said system,

said associated information determining module makes determination except a case in which the transmission time extracted by said information analyzing module is earlier than broadcasting time zones of all the programs registered in said reserved program database.

5. A broadcast receiving system according to claim 4, wherein the information acquired from outside of said system is an electronic mail.

6. A broadcast receiving system according to claim 4, wherein the information acquired from outside of said system is Web data.

7. A computer readable medium storing a program read and executed by a computer including a tuner receiving broadcasting signals, a storage device and a communication device connected to a network and having a function of recording video signals in the broadcasting signals received by said tuner on said storage device, and a function of acquiring the information via said communication device, to make the computer function as:

a reservation module registering a channel and a broadcasting time zone of a program designated by a user in a reserved program database, and setting and storing in a storage device a condition of a restriction period;

a keyword extracting module extracting, for every program of which channel and broadcasting time zone are registered in the reserved program database, a keyword from program contents contained in the program information and registering the keyword in a keyword database;

a display module displaying information acquired via said communication device on a screen;

an information analyzing module analyzing a content of the information acquired via said communication device and extracting the keyword from the information;

a restriction period determining module determining as a restriction target program, the program of which channel and broadcasting time zone are registered in the reserved program database and of which broadcasting time zone is within the restriction period defined under the condition of the restriction period;

an associated information determining module calculating an association level between the keyword registered in said keyword database for the program determined as the restriction target program by said restriction period determining means and the keyword extracted by said information analyzing means, and determining whether or not there is the program with the calculated association level exceeding a predetermined threshold value; and

an alarm issuing module issuing an alarm showing that said associated information determining means determines that there is the program with the association level exceeding the threshold value.

8. A method of restricting an alarm related to a reserved program by which a broadcast receiving system including a tuner receiving broadcasting signals, a storage device and a communication device connected to a network and having a function of recording video signals in the broadcasting signals received by said tuner on said storage device, executes steps of:

registering a channel and a broadcasting time zone of a program designated by a user in a reserved program database, and setting and storing in a storage device a condition of a restriction period;

extracting, for every programs of which channels and broadcasting time zone are registered in the reserved program database, a keyword from program contents contained in the program information and registering the keyword in a keyword database;

analyzing a content of the information when acquiring information via said communication device;

determining as a restriction target program, the program, of which channel and broadcasting time zone are registered in the reserved program database and of which broadcasting time zone is within the restriction period defined under the condition of the restriction period;

calculating an association level between the keyword registered in said keyword database for the program determined as the restriction target program and the keyword extracted from the information; and

issuing, if there is the program with the association level exceeding the threshold value, an alarm showing this purport.
