Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a video recording device such as a VTR, a DVD recorder, a hard disk recorder, and the like.
[0002]
[Prior art]
As a hard disk recorder that records a television program on a hard disk, a function is provided in which, when a user sets a keyword, a program corresponding to the keyword is searched from an electronic program guide (EPG) acquired via the Internet and automatically recorded. Are already being developed.
[0003]
In order to predict a user's preference for a program, viewing history information of the user's television program (information on which program has been watched for how long, information on the content of the viewed program, genre, performer, etc., etc.) is required. The effectiveness is reported in a paper "Study of TV program recommendation system based on user's viewing history" (The 54th Annual Conference of IPSJ VOL.4pp.245-246).
[0004]
In the case where the video recording apparatus is to be provided with a function of predicting the user's program preference based on the viewing history information of the user's television program and automatically recording the user's favorite program, Viewing history information is required. However, video recording devices such as VTRs, DVD recorders, hard disk recorders, and the like usually have a separate housing from the television receiver, and therefore cannot directly receive program viewing information from the television receiver.

[Problems to be solved by the invention]
According to the present invention, a program viewing information can be obtained, and a function of predicting the user's preference of the program based on the viewing history information of the user's television program and automatically recording the user's favorite program is provided. It is an object of the present invention to provide a video recording device capable of performing the above.
[0007]
[Means for Solving the Problems]
The invention according to claim 1 is a television remote control signal receiving means for receiving a television remote control signal, a television program information acquiring means for acquiring television program information, and a television remote control received by the television remote control signal receiving means. A program viewing information generating means for generating and storing user program viewing information based on the signal and the TV program information obtained by the TV program information obtaining means is provided.
[0008]
According to a second aspect of the present invention, in the video recording apparatus according to the first aspect, the program viewing information generation unit determines whether the television receiver is on or off based on a television remote control signal received by the television remote control signal reception unit. Means for acquiring a selected channel number and its date and time information and storing the information in a nonvolatile remote control information storage memory; information stored in the remote control information storage memory; and a television program acquired by the television program information acquisition means A means is provided for generating and storing program viewing information of the user by collating the information with the information.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 shows an example of installation of a video recording device.
[0011]
The video recording apparatus 1 is arranged at a position where a remote control signal for television from a remote controller (hereinafter, referred to as a television remote control) 3 of the television receiver 2 can be received. The video recording device 1 has a TV program viewing history information generation function.
[0012]
FIG. 2 shows a configuration provided in the video recording device 1 for realizing a TV program viewing history information generation function.
[0013]
The TV remote control signal receiving block 11 receives a TV remote control signal from the TV remote control 3. The TV remote control signal received by the TV remote control signal receiving block 11 is sent to the CPU 12. The CPU 12 generates the following TV remote control signal reception information based on the TV remote control signal transmitted from the TV remote control signal reception block 11 and the time information from the timer 13, It is stored in the remote control information storage memory 14.
[0014]
(A) ON / OFF state of the television receiver 2: specifically, date and time information when the ON button is depressed and date and time information when the OFF button is depressed (b) Channel selection information: specific Includes the channel number selected and date and time information when the channel was selected.
By the way, the specifications of the TV remote control signal from the TV remote controller 3 are determined for each manufacturer. Therefore, the setting of the TV remote control signal receiving block 11 can be changed by the TV manufacturer setting switch 15 so that the TV remote control signal from the TV remote controller 3 of various manufacturers can be received. Such a function is mounted on, for example, a remote controller of a video tape recorder that can operate a television (including models of other manufacturers), and is a general-purpose technology, and thus details thereof are omitted.
[0016]
The CPU 12 stores the television program information acquired via a television program information acquisition unit (not shown) in a non-volatile television program information storage memory 16. The TV program information acquisition means periodically acquires TV program information via the Internet or data broadcasting. The TV program information includes the time schedule of the TV program, the genre and content of the program, information on the cast, and the like.
[0017]
As shown in FIG. 3, the CPU 12 compares the TV remote control signal reception information stored in the remote control information storage memory 14 with the TV program information stored in the TV program information storage memory 16 and specifies the program watched by the user. At the same time, the genre of the program, the contents of the program, and information on the performers are obtained. The program viewing information is generated by organizing the information thus obtained, and the generated program viewing information is stored in the program viewing information database 17.
[0018]
In this example, as shown in FIG. 3, the program viewing information is composed of four types of viewing rate for each program, total viewing time for each program, total viewing time for each genre, and total viewing time for each performer. I have. What information is used as the program viewing information can be arbitrarily determined.
[0019]
The audience rating of a program refers to the percentage (%) of the time during which the user was actually viewing (selecting) the program in the program broadcast time zone of the program that was viewable. For example, consider the case where the user is watching television during the one hour period from 7:00 PM to 8:00 PM. It is assumed that a program A, a program B, a program C, and a program D (each of which is a one-hour program) are being broadcast in this time zone. Assuming that the user's viewing time At to Dt for each of the programs A to D is At = 10 minutes, Bt = 0 minutes, Ct = 5 minutes, and Dt = 45 minutes, the audience rating As to Ds of each program is As = (10/60) x 100 = 16.7%, Bs = 0%, Cs = (5/60) x 100 = 8.3%, Ds = (45/60) x 100 = 75%.
[0020]
Based on such program viewing information, it becomes possible to predict a user's favorite program, and it is also possible to automatically record the predicted user's favorite program.
[0021]
In order to predict a user's favorite program based on the program viewing information as described above, for example, it is conceivable to predict a program with a high program audience rating as a user's favorite program. However, this is only an example, and it goes without saying that the user's favorite program may be predicted by another method based on the program viewing information as described above.
[0022]
【The invention's effect】
According to the present invention, it is possible to obtain program viewing information, predict a user's program preference based on the user's television program viewing history information, and automatically record a user's favorite program. A video recording device that can be provided is obtained.
