Description

  The present invention relates to a target viewing determination apparatus capable of determining whether or not a program is viewed with a purpose, and an operation method thereof.

  Conventionally, as a technique for estimating the situation of the user in front of the television, a technique is generally used in which a camera is mounted on the television and the situation is estimated by sensing using an image processing technique. Non-Patent Document 1 shows a case in which face recognition is performed in addition to moving object detection by image processing technology, and it is used not only for the presence of the user but also for the active energy saving by determining the presence / absence of viewing. Yes. In this example, a human sensor using a camera is used to determine whether or not the user is watching the television. If the user is not viewing, the television screen is erased.

Atsushi Tsurumi "Image Recognition and Human Interface 3. Human Interface Using Image Recognition 3-1 Intelligent Human Sensor", Journal of the Institute of Image Information and Television Engineers, Vol. 64 No. 12 Page. 1809-1811

  As described above, conventionally, a human sensor using a camera determines whether or not the user is watching the television, and if not, performs a process of erasing the television screen.

  However, in the method of estimating the user's viewing situation with the camera, when viewing from a point outside the angle of view of the camera or when the face or part of the body is hidden by an obstacle, the viewing situation is correct. The problem is that it cannot be estimated.

  In order to solve this problem, it is assumed that a plurality of cameras are installed or a plurality of infrared sensors or the like are arranged in the room. However, the effect of acquiring the viewing status is not worth the cost.

  Therefore, in order to solve the above problems, the situation that the user selects and watches a program with the purpose is extracted from the operation log of the television, and combined with the technology for determining the viewing situation of the prior art, it is multimodal. It is proposed to make a decision by complementing the information. For example, even if you are watching at a position outside the camera angle of view and the viewing status cannot be estimated correctly, if the program is selected with the purpose, it will not be erased. It is possible to judge the situation together with the obtained image information. “Viewing with a purpose” refers to a situation in which a user wants to view one program before the user selects the program and then views the program. For example, in a daytime information program, you know the existence of a drama that is broadcast tonight, decide to watch the drama, and actually watch the drama at night.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a target viewing determination apparatus capable of determining whether or not a program is viewed for the purpose and a method for operating the same. is there.

  In order to solve the above-described problem, the first aspect of the present invention is to broadcast a channel log storage unit that stores a channel log indicating a history of a channel on which a viewed program is broadcast, and one or more programs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a target viewing determination apparatus according to the present embodiment.
The target viewing determination device 1 is a device that determines whether or not the viewing of the program is a purposeful viewing when the user views a program shown on a television (not shown) or the like.

  “Targeted viewing” refers to a situation in which a user views a program after deciding on one program to view.

  The target viewing determination apparatus 1 includes an operation log storage unit 11 that stores an operation log of a remote controller for remotely operating a television and the like, and operation pattern information indicating a remote control operation pattern and a situation when the operation pattern is operated. An operation pattern information storage unit 12 for storing the channel, a channel log storage unit 13 for storing a channel log indicating a history of a channel on which the viewed program is broadcasted, a channel for broadcasting the program for one or more programs, and a broadcast A program guide storage unit 14 that stores a program guide showing a time zone, a viewing log storage unit 15 that shows a history of a channel that broadcasts a viewed program, a program guide acquisition unit 16 that acquires a program guide from the outside, and an operation An operation log analysis unit 17 that determines whether or not a situation indicated by the pattern information has occurred using an operation log, and detects program transitions A program transition monitoring unit 18, a program story determination unit 19 that determines whether or not the program has story property, a habit viewing determination unit 101 that determines whether or not the program is customarily viewed, and a program A target viewing determination unit 102 that determines whether or not the viewing of the program is a purposeful viewing, and a target viewing identifier 103 that is used to determine whether or not the viewing of the program is a purposeful viewing.

  Here, the program table includes, for a large number of programs, a channel on which the program is broadcast, a start time (exactly, start date and time) as a part of information indicating a broadcast time zone, a program name, a genre, and the like. It is assumed that it is configured as follows.

FIG. 2 is a diagram illustrating an example of an operation log stored in the operation log storage unit 11.
The operation log storage unit 11 stores an operation log of a remote controller operated to view a program. The operation log is a log having information indicating the operation date and time and the operated button of the remote control for each operation.

  The operation log may be acquired by interposing an operation log acquisition device between the remote control and the television, for example. Note that the operation log acquisition method is not limited to this.

  FIG. 3 is a diagram illustrating an example of operation pattern information stored in the operation pattern information storage unit 12.

  The operation pattern information storage unit 12 stores one or more pieces of operation pattern information. The operation pattern information includes one operation pattern of the assumed remote controller and a status flag indicating a status when the operation pattern is operated.

  When the operation pattern “determine button or channel button is pressed” is performed, a situation where the remote controller is used has occurred, and the status flag “use of remote controller” indicates the situation.

  If the operation pattern “program guide button was pressed”, “operation button was pressed”, or “decision button was pressed” was performed, there was a situation that the list display was made, and the status flag “List display” indicates the situation.

  When the operation pattern “Different channel buttons are pressed continuously” is performed, there is a situation in which zapping (an act of frequently switching channels with the remote control and selecting channels while comparing multiple channels) has occurred. The status flag “zapping” indicates the status.

  When the operation pattern “the time when the operation log is read is before the start time of the program”, there is a situation that the program has been viewed from the start, and the status flag “view from the start of the program” indicates the situation It is.

  When the operation pattern “Power button was pressed” is performed, it is assumed here that a situation occurs in which the program is viewed immediately after power-on, and the status flag “view immediately after power-on” It shows the situation.

  FIG. 4 is a diagram illustrating an example of a channel log stored in the channel log storage unit 13.

  The channel log storage unit 13 stores a channel log indicating the history of the channel on which the viewed program is broadcast. Each time the channel is switched or the TV is turned off, the channel log has the date and time, information indicating the channel or TV turned off after switching, and information indicating the duration of the channel (only when the channel is switched). This is a log.

  The channel log may be acquired, for example, by interposing a channel log acquisition device between the remote control and the television. Note that the channel log acquisition method is not limited to this.

FIG. 5 is a diagram illustrating an example of a viewing log stored in the viewing log storage unit 15.
The viewing log storage unit 15 stores a viewing log indicating a history of a channel that broadcasts the viewed program. The viewing log is a log having information indicating the date and time of power-on, the channel at that time, the channel after switching, or the power-off of the TV every time the TV is turned on, the channel is switched or the TV is turned off. It is.

  The viewing log may be acquired, for example, by interposing a viewing log acquisition device between the remote control and the television. Note that the viewing log acquisition method is not limited to this.

FIG. 6 is a flowchart showing the operation of the program transition monitoring unit 18.
The program transition monitoring unit 18 first reads the channel log of the latest date and time from the channel log storage unit 13 (S1), and the channel indicated by the channel log is the channel indicated by the previous channel log read in the same manner. It is determined whether or not they are the same (S3). That is, the program transition monitoring unit 18 determines whether or not the channel is switched by the user operating the remote control.

  If the channel change is different from the previous channel (S3: NO), that is, if the channel is switched, the program transition monitoring unit 18 reads the program table from the program table storage unit 14, and reads the program table from the program table according to the channel log read in step S1. The program name, start time, genre, etc. of the program 10 minutes after the current time of the indicated channel are read (S5). The reason for 10 minutes later is that the user may switch channels before the program starts.

  If the same as the previous channel (S3: YES), the program transition monitoring unit 18 reads the program table from the program table storage unit 14, and from the program table, the program at the current time of the channel indicated by the channel log read in step S1. The program name, start time, genre, etc. are read out (S7).

  Next, the program transition monitoring unit 18 determines whether or not the program name read in step S7 is the same as the previous program name read in the same manner (S9). That is, the program transition monitoring unit 18 determines whether or not the program has ended at the end time of the program and the next program has started without the user operating the remote control.

  When the program transition monitoring unit 18 is different from the previous program name or the like (S9: NO), or when the process of step S5 is completed, the program name, start time, genre, etc. read out in the immediately preceding step S5 or step S7 Is notified to the operation log analysis unit 17, the program story determination unit 19 and the habit viewing determination unit 101 (S11).

FIG. 7 is a diagram showing an example of the notified program name, start time, and genre.
The program name is, for example, “15th anniversary special drama project“ fire investigator ””, the genre is “drama”, and the start time is “2012/11/10, 21:00:00”.

  Returning to FIG. 6, if the program transition monitoring unit 18 is the same as the previous program name or the like (S9: YES), or if the process of step S11 is completed, the program transition monitoring unit 18 waits for a certain time (for example, 60 seconds), and then proceeds to step S1. Return to.

  Returning to FIG. 1, if there is a notification from the program transition monitoring unit 18, that is, if a program after transition is detected, the habitual viewing determination unit 101 reads the viewing log / program table acquisition unit 16 from the viewing log storage unit 15. Each of the program guides is read out, and based on the viewing log and the program guide, it is determined whether or not the notified program after the transition is customarily viewed, and the determination result is notified to the target viewing determination unit 102.

  The habit viewing determination unit 101 determines, for example, that the program after the transition is to be viewed habitually if the condition that the program has been viewed more than once in the past month is satisfied, On the other hand, if the condition is not satisfied, it is determined that the program after the transition is not habitually viewed.

  The habitual viewing determination unit 101 may add a viewing log related to the current program transition to the viewing log storage unit 15.

  If there is a notification from the program transition monitoring unit 18, the program story property determination unit 19 determines whether or not the program has story property based on the notified genre, and the determination result is sent to the target viewing determination unit 102. Notice.

  For example, if the genre is “drama”, “movie”, “animation”, “special effects” or the like, the program story property determination unit 19 determines that the program has story property, and otherwise, the program story property. It is determined that it does not have.

  When notified from the program transition monitoring unit 18, the operation log analysis unit 17 reads the operation log from the operation log storage unit 11 and all the operation pattern information from the operation pattern information storage unit 12, and operates in the operation pattern information. It is determined whether or not the pattern matches the operation log, and based on the determination result, it is determined whether or not a status flag in the operation pattern information has occurred, and the determination result is notified to the target viewing determination unit 102 To do.

FIG. 8 is a diagram illustrating an example of the read operation log.
The operation log is for the past 60 seconds, for example, and the read time is “21:19:00”.

  Here, if the notified start time is “21:00:00”, it does not match the operation pattern “time when the operation log is read is before the start time of the program” in FIG. It can be seen that there is no situation (viewing from the start of the program) corresponding to “from viewing”.

  If the time when the operation log is read is before the start time, for example, after 5 minutes, it may be viewed from the start of the program for convenience. On the other hand, even if the time when the operation log is read is before the start time, if it is 10 minutes or more ago, it may not be viewed from the start of the program.

  Further, it can be seen from the operation log that the user zapped “6ch”, “4ch”, and “5ch”. That is, since the operation log matches the operation pattern “different channel buttons are continuously pressed” in FIG. 3, it can be seen that a situation (zapping) corresponding to the situation flag “zapping” occurs.

  In addition, the operation log has no evidence of displaying a table listing program names, genres, and contents such as a program table, a recording list, and a VOD list, and thus such a display (list display) is not performed. I understand. That is, the operation log does not match the combination of the operation patterns “program guide button pressed”, “operation button pressed”, and “decision button pressed” in FIG. It can be seen that the situation (list display) corresponding to “” has not occurred.

  Further, since the operation log matches the operation pattern “determine button or channel button is pressed” in FIG. 3, it can be seen that the situation corresponding to the situation flag “use of remote control” (use of remote control) has occurred.

  In addition, since the operation log matches the operation pattern “power button is pressed” in FIG. 3, a situation corresponding to the status flag “viewing immediately after power-on” (viewing immediately after power-on) has occurred. Recognize.

FIG. 9 is a diagram illustrating an example of a determination result for each status flag.
The determination result includes a flag indicating whether or not a situation corresponding to each information flag has occurred.

  Taking the explanation given using FIG. 8 as an example, a situation corresponding to the situation flag “use of remote control” has occurred, so the flag of the determination result is “1”.

  Further, since the situation corresponding to the situation flag “list display” has not occurred, the determination result flag is “0”.

  Further, since a situation corresponding to the situation flag “zapping” has occurred, the flag of the determination result is “1”.

  Further, since a situation corresponding to the situation flag “viewing from the start of the program” has not occurred, the flag of the determination result is “0”.

  Further, since a situation corresponding to the situation flag “viewing after power-on” has occurred, the flag of the determination result is “1”.

  Returning to FIG. 1, the target viewing determination unit 102 determines whether or not the viewing of the program after the transition is a target viewing based on the determination result information including each determination result. The target viewing determination unit 102 uses the target viewing identifier 103 for this determination.

FIG. 10 is a diagram illustrating an example of the determination result information.
The determination result information includes, for example, a flag indicating a determination result by the habit viewing determination unit 101, a flag indicating a determination result by the program story determination unit 19, and one or more flags indicating a determination result by the operation log analysis unit 17. Including.

  Therefore, according to the target viewing determination apparatus of the present embodiment, it is possible to determine whether or not the viewing of the program is an intended viewing. For example, even if the user is viewing at a position deviating from the angle of view of the camera that monitors the user and the viewing situation cannot be estimated correctly, it can be determined whether the viewing of the program is the intended viewing.

Here, a method for constructing the target viewing discriminator 103 will be described.
As shown in FIG. 11, determination results of the habit viewing determination unit 101, the program story determination unit 19 and the operation log analysis unit 17, that is, determination result information as shown in FIG. In addition, the teacher data indicating whether or not the viewing of the program is the intended viewing when the viewing corresponding to the determination result information is performed is input to the discriminator construction unit 104 from the outside. The classifier construction unit 104 may be included in the target viewing determination apparatus 1 and teacher data may be input from outside the target viewing determination apparatus 1.

FIG. 12 is a diagram illustrating an example of learning data including determination result information and teacher data.
The learning data in the first row shows, for example, a flag “0” for “habitually” indicating a determination result that the program after transition is not habitually viewed, and a determination result that the program does not have story characteristics. “Story” flag “0” and determination result information including each flag of FIG. 9 and teacher data “non-purpose” indicating that the viewing of the program after the transition is not intended viewing.

The learning data on the tenth line includes, for example, a flag “1” indicating “judgment” indicating that the program after transition is customarily viewed, and a judgment result indicating that the program has no story. “Story” flag “0”, “remote control use” flag “1”, “zapping” flag “0”, “list display” flag “1”, “view from program start” flag “ “1” and “viewing after power-on” flag “0”, and teacher data “non-purpose” consisting of teacher data “purpose” indicating that the program viewing after the transition is intended viewing “Purpose” is a case where experience or the like indicates that the viewing of the program after the transition when the situation corresponding to the determination result information has occurred is not the intended viewing, while the teacher data “Purpose” With purposeful viewing This is when it is known from experience.

  For example, when all the following three conditions are satisfied, the teacher data is “purpose”, and when any of the conditions is not satisfied, the teacher data is “non-purpose”.

Condition 1: The user knew the time when the program was broadcast before the program selection operation, or the program allows the user to determine the start time, such as recording or VOD.
Condition 2: Before the program selection operation, the user knew the contents of the program (program name, genre, performer, etc.).
Condition 3: Before the program selection operation, the user decided to view the program.

  The discriminator constructing unit 104 constructs the target viewing discriminator 103 using one or more, preferably many, such learning data.

  The classifier construction unit 104 uses, for example, a statistical method such as machine learning when constructing the target viewing classifier 103. Various techniques such as decision trees, naive Bayes classifiers, and neural networks can be considered as techniques for constructing classifiers from learning data. For example, support described in “Vapnik: Statistical learning theory, A Wiley-Interscience Publication, 1998” Vector machines can be used. Here, as the target viewing discriminator 103, a non-linear classifier using a support vector machine is constructed using kernel tricks.

  The concept of a support vector machine is to build a separation hyperplane that separates so that the margin is maximized, but in most cases it cannot simply be linearly separated. Therefore, a support vector machine can be constructed using a technique called mapping kernel trick data to a high-dimensional feature space to construct a discriminant function that can be separated nonlinearly.

  The target audience discriminator 103 constructed in this way is constructed so as to output a negative judgment result when the judgment result information is the same as the judgment result information included in the learning data of the first row, for example. If so, a negative determination result is notified to the target viewing determination unit 102. In this case, the target viewing determination unit 102 determines that the viewing of the program after the transition is not a target viewing and outputs the determination result to the outside.

  On the other hand, if the target viewing discriminator 103 is constructed so as to output a positive determination result when the determination result information is the same as the determination result information included in the learning data in the tenth row, for example, Is sent to the target viewing determination unit 102. In this case, the target viewing determination unit 102 determines that the viewing of the program after the transition is a purposeful viewing, and outputs the determination result to the outside.

  In the present embodiment, for example, if the accuracy of determining whether or not the viewing of the program after the transition is a purposeful viewing may be low, the habit viewing determination unit 101 is omitted, and the target viewing determination unit 102 is Based on the determination result of the operation log analysis unit 17 and the determination result of the program story property determination unit 19, it may be determined whether or not the viewing of the program after the transition is the intended viewing.

  Further, if the determination accuracy may be lower, the program story determination unit 19 is also omitted, and the target viewing determination unit 102 is based on the determination result of the operation log analysis unit 17 for the purpose of viewing the program after the transition. It may be determined whether or not there is. In that case, the program guide may not indicate the genre of the program.

  One or both of the program guide acquisition unit 16 and the discriminator construction unit 104 may not be included in the target viewing determination apparatus 1.

  A computer program for causing a computer to function as the target viewing determination apparatus 1 can be recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, and a magnetic tape, and communication such as the Internet. It can be distributed widely through the network.
