When the viewing device 140 receives a BS digital broadcast signal and a CS digital broadcast signal, it demultiplexes the stream (broadcast signal) sent by the broadcast wave, as in the case of receiving the broadcast signal of the terrestrial digital television broadcast. Processing and descrambling are performed, and video data is output to the display device 160 and audio data is output to the speaker 161 .

The example of the viewing device 140 in FIG. 2 is an example in which the tuner for digital terrestrial television broadcasting incorporates one of the digital terrestrial television tuners 201-1. may be incorporated. Similarly, the viewing device 140 may incorporate a plurality of BS digital broadcast tuners and a plurality of CS digital broadcast tuners.

The control unit 142 controls the entire viewing device 140 . Also, the control unit 142 acquires the viewing history of the program viewed by the user of the viewing device 140 and transmits the acquired viewing history to the server 120 via the network 180 . The control unit 142 has a network I/F 181 that is an I/F with a communication network 180 and a remote controller I/F 182 that is an I/F with a remote controller (remote controller) 190 as I/F with the outside.

Here, the viewing history indicates the history of all programs received by the viewing device 140 through a plurality of tuners. Specifically, for example, the user of the viewing device 140 receives the broadcast wave and views the program A displayed on the display device 160 while simultaneously recording the program B by the recording unit 143, which is the recording function of the viewing device 140. If so, the control unit 142 stores a live viewing history that is a history of viewing program A (referred to as live viewing), a playback viewing history of playback viewing of program B (viewing of playback of a recorded program), and furthermore, It is possible to acquire a reserved viewing history that is viewing by viewing reservation of the program C. FIG.

For playback viewing, for example, by reserving a program to be recorded in advance by the reservation function of the recording function, the designated program B is recorded in the recording unit 143 at the designated time, and only the recording is performed without being displayed on the display 160. In some cases.
As described above, the viewing device 140 of the present embodiment can take various viewing modes such as live viewing, recording/playback viewing, and reserved viewing by viewing reservation.

The various viewing histories described above may be composed of, for example, a combination of channel number, program name, broadcasting station name, viewing start time, and viewing end time. The control unit 142 stores the above-described various viewing histories for each type in a storage area (not shown) that internally holds the acquired viewing histories.

The control unit 142 assigns an identification number that the viewing device 140 has to the acquired viewing history, and transmits the acquired viewing history to the server 120 via the network 180 at an arbitrary timing.
FIG. 3 is a diagram schematically showing a configuration example of the server 120. As shown in FIG.
The collection unit 122 collects viewing histories sent from the viewing device 140 via the network 180 and stores them in an internal storage area (not shown) for each given identification number, and also collects the viewing histories. information relating to storage of the received viewing history, such as the storage address of and the assigned identification number, is transmitted to the identification management unit 121 .

The identification management unit 121 stores and manages the information regarding storage and the identification number sent from the collection unit 122 . Thus, the identification management unit 121 can manage viewing history data (viewing log) for each identification number of the viewing device 140 .
The analysis unit 123 analyzes the viewing history stored in the collecting unit 122, for example, the viewing history of the specified identification number for the specified period. The analysis results are sent to the service providing unit 124, and the service providing unit 124 provides services based on the sent analysis results.

Note that the server 120 shown in FIGS. 1 and 3 may include a display unit (not shown) capable of displaying the content of the service provided by the service providing unit 124. FIG. Alternatively, the server 120 may display the contents of the service provided by the service providing unit 124 on a connected external display device (not shown). Alternatively, analysis unit 123 and service providing unit 124 may be outside server 120 .

If the service providing unit 124 is outside the server 120, the analyzing unit 123 and the service providing unit 124 may be inside a PC (personal computer), for example. Alternatively, the analysis unit 123 and the service provision unit 124 may be in a mobile terminal such as a smart phone or tablet. In this case, the PC or mobile terminal is connected to the server 120 via the network 180 and can access the server 120 . Therefore, the PC or mobile terminal can acquire the viewing history information stored in the collection unit 122 at any location. Also, the operator of the PC or mobile terminal can perform the analysis by the analysis unit 123 at any place. Further, the operator of the PC or mobile terminal can provide services and value-added data at any location by the service providing unit 124 based on the analysis result of the analyzing unit 123 . A mobile terminal including analysis unit 123 and service providing unit 124 may be called a viewing history analysis device.

The service provided by the service providing unit 124 may be the provision and display of visualized data based on the analysis result of the analysis unit 123, for example. The visualized data is, for example, a viewing history group A, which is a set of viewing histories of the viewing device 140 having an identification number that the analysis unit 123 has analyzed, from among the vast amount of viewing history collected by the collection unit 122. Furthermore, by reorganizing the viewing history group A from various viewpoints using various parameters, it is easy for the user to understand that there is a certain tendency in the viewing history group A, which seems to be chaotic, using graphs and tables. It is to provide and display in a form.

Such a viewing history group A visualization service can be useful information for the side that broadcasts programs to the viewing device 140, such as the broadcasting station 140, program production companies, and program sponsors.
The example of FIG. 3 shows an example in which the service data provided by the service providing unit 124 is connected so as to be visible from the personal computer 311 via the network 310 .

FIG. 4 shows an example of services displayed on the screen 322 of the personal computer 311, for example.
For example, the table in the left display area 331 displays various buttons for controlling or switching the service information screen on the right side, conditions when the service information is generated, and the like. for example,
・What area is the service information to be provided (Kanto in the example in the figure),
・How long will the service information be provided?
・Which channel is the service information to be provided (NNKK broadcast in the example of the figure),
・Whether the demograph, which is the service information to be provided, is, for example, a part of the region or the whole region (in the example of the figure, the whole region),
・Which viewing history is used as the viewing data, which is the service information to be provided (live in the example in the figure),
・Whether or not the service information to be provided is multi-organization (not multi-organization in the example of the figure),
- Whether the program ranking, which is the service information to be provided, is generated by the number of overlapping devices as viewing devices for two programs, by the number of viewing devices for only one program, or by the number of viewing devices for only the other program Whether to generate (in the example in the figure, the number of duplicate devices is selected),
・What criteria are used to determine whether or not a program has been viewed (in the example in the figure, 1/3 of the program is considered to have been viewed),
・The program ranking is generated from the viewing data of the program that is separated by how many hours from the program used as the analysis standard (in the example of the figure, it is separated by about one week, which is 150 hours apart),
etc. can be selected.
・In addition, when the reference data is the total number of devices (Monday, March 11 in the example of the figure)
・Furthermore, the user classification of the total number of devices is also shown.

On the right side of the display area 331, a table is displayed in a program area 332 for one week of one channel. The table of the program area 332 is partitioned horizontally by days of the week and vertically by time. In this program area 332, the frames are not particularly identified, but are simply divided. Also, at least one day may be displayed.

Further, on the right side of the program area 332, a table of programs is displayed in a similar program area 333 as well.
The heat map on the left displays the status of selected program A for program B (1-N) over the past week. At this time, regardless of the broadcast time of program A, the display is displayed by turning back from Monday to Sunday, for example, and the right side of the time of selected program A is the time of one week before. Note that the heat map displays colors with different color temperatures according to the rank in each program frame.

The heat map shows the ranking of the selected ranking index, duplicate device rate/duplicate share. At this time, it is possible to change how many hours before the start of the program A the ranking order is displayed, depending on the "ranking display time" which is an object of tallying the ranking. This is because it is possible to analyze only the most recent program because the program A is most likely to have a high publicity effect when it is broadcast. The heatmap colors are color-coded by the selected ranking metric.

Furthermore, the ranking on the right side displays the ranking of the programs within the total time of the "ranking display time" according to the selected ranking index. The right side shows a bar graph, where the bars are displayed with three levels of identification. In this bar graph, the left identification part of the bar shows the devices that watched only program A, the central identification part of the bar shows the devices that watched both program A and program B, and the right identification part of the bar shows the devices that watched only program B. It is the percentage of equipment that has This corresponds to displaying Venn diagrams for a plurality of programs side by side. The total number obtained by adding the left identification part and the center identification part of the bar matches the number of viewing apparatuses for program A, so the number matches regardless of program B. FIG. Black triangles represent overlapping shares.

The duplicate device rate of the ranking indicator corresponds to the central identification part of the bars in the bar graph, and the duplicate share corresponds to the black triangle (the number of duplicate devices/the length of the bar graph (A+AB+B)).
In the above program area 333, when one frame (for example, 332-1) of the left program area 332 is clicked with the cursor, the corresponding frame 333-1 becomes white.

Then, as will be described later, the number of devices that have duplicated viewing between program A corresponding to frame 332-1 and other programs B (1 to N) (the number of duplicate viewing devices that have viewed live ) is determined by viewing history analysis. Furthermore, rankings are given to the programs in each frame according to the number of overlapping devices. In the program area 333, a ranking is displayed for each frame, and the rankings are displayed in different colors. Such a map is called a heat map.

In the table of the display area 334 on the right side of the program area 333, the program names are displayed sequentially from top to bottom on the screen from the top of the ranking, and the broadcast date and time are displayed on the right side of each program name. there is
Furthermore, in the table of the area 335 on the right side of the display area 334 indicating the ranking, bar graphs are displayed so as to be arranged in the horizontal direction for each program name. In the bar graph, for each bar, the number of viewing devices that viewed only program A, the number of viewing devices that viewed only program B (programs of each ranking), and the number of viewing devices that viewed both programs A and B were color-coded. is displayed. In the case of the program ranked first in the figure,
Percentage of the number of viewing devices As that viewed only program A: not described;
Ratio of the number Bs of viewing devices that viewed only program B (program of each ranking): 1.306
Ratio of the number of duplicate viewing devices AsBs that viewed both programs A and B: 1.388
is exemplified. The sum of the ratio of the number of viewing devices that viewed only program A and the ratio of the number of viewing devices that viewed both programs A and B (ASBS) is the same in any ranking, but the ratio of the number of duplicate viewing devices is Each ranking is different.

Here, black triangles indicate overlap share (percentage). Duplicate shares are
= (the number of overlapping devices/bar length (As + AsBs + Bs)).
Looking at the display of the above-described program ranking, it is easy to understand because it is visualized which time period of the program is effective for program advertisement.

In the above example, as program A, the program in the frame 332-1 from 16:00 to 18:00 on Thursday is specified. However, the system can also specify other frames. Then, in the same way as before, the overlapping viewing device information of the program X in the specified frame and the other programs B (1 to N) are obtained. Then, the ranking of programs with a large ratio of the number of duplicate viewing devices is displayed. Therefore, by specifying several frames, the user can know the program with the highest ratio of the number of duplicate viewing devices (high ranking), and can know (search for) the program that effectively advertises the program. )be able to.

It is also possible to automatically perform the above designation, search for a plurality of programs with high rankings, and determine the program with the highest ratio of duplicate viewing devices.
In the above embodiment, two program areas 332, 332 for designating program frames and 333, for displaying heat maps, are displayed. However, the invention is not limited to such embodiments.

FIG. 5 shows an example of another display form. In this display form, the program area 332 is omitted, and the program area B333 displaying the heat map is also used as the program A specification table.
In this program area B333, when the frame of program A on Thursday from 16:00 to 18:00 is designated by the cursor, it is determined whether or not programs B (1 to N) surrounding program A have been viewed in duplicate. determined by viewing history analysis. Furthermore, rankings are given to the programs in each frame according to the number of overlapping devices. In the program area 333, a ranking is displayed for each frame, and the rankings are displayed in different colors.

In addition, in a display area B334 on the right side of the program area B333, the program names are displayed sequentially from top to bottom on the screen from the top of the ranking, and the broadcast date and time are displayed on the right side of each program name. . Also, the duplication device rate is displayed next to each program name.
In the case of the above display mode, the heat map and the ranking can be enlarged and displayed as compared with the display mode of FIG. Also, the system may be such that the display modes (FIGS. 4 and 5) can be switched.

In other words, the display of FIG. 5 is obtained by means of obtaining data for visualization, obtaining an output for displaying a program area representing at least a plurality of days of the same channel and representing a plurality of program time slots, By designating the time slot of one program out of the plurality of programs, it is possible to determine the number of duplicate viewing devices that have viewed the one program in duplicate with the other plurality of programs out of the plurality of programs. It can be used as an interface to

Although the programs are ranked and displayed in order of rank in FIGS. 4 and 5, the present invention is not limited to such an embodiment. For example, programs may be categorized by genre, the ranking of the programs may be attached within the genre, and the display may be in rank order, or the rank order may be random, and the ranking may be displayed numerically next to the program name. good too. There are various forms of display, and they may be switchable. Also, the rank of programs may be classified by day of the week. Program rankings may then be attached within each day of the week.
May be attached. In addition, ranks may be color-coded.

FIG. 6 shows a flow chart and processing blocks executed by operating the personal computer 311 shown in FIG. For example, when the start button is clicked and a channel is selected, a program table model (program areas 332, 333) as shown in FIG. 4 is displayed (step AS1).

Here, the user selects an arbitrary program frame (frame 332-1 in the previous example). That is, program Ax is selected (specifically, viewing-related data of program Ax) (step AS2). Then, analysis by the analysis unit 123 of the server 120 starts, another program By is automatically selected (specifically, the viewing-related data of the program By is automatically selected) (step AS3), and the program Ax and the program By are viewed. Data processing is started (step AS4). In this step
The number of devices that viewed only Ax, the number of devices that viewed only By, and the number of duplicate devices that viewed both Ax and By are retrieved. Next, another program By is updated (specifically, updated to the viewing-related data of the next B(y+1)). Then, returning to step SA3, the number of devices Ax that viewed only B(y+1) and the number of duplicate devices that viewed both B(y+1) are checked.

When a predetermined number of pieces of program B information and pieces of program A information are analyzed in this manner, the heat map described above is created. The data used in step AS3 is the viewing-related data (viewing log) stored in the memory M1 of the server 120. FIG. Various data detected in step AS4 are accumulated in the memory M2 of the server or the personal computer, which is the operation unit, and are used to create a heat map (step AS7) and rank data (step AS8). The created reference data is displayed on the screen by, for example, the display processing section of the personal computer 31 (step AS9). After that, it will be in the state of waiting for the next operation.

FIG. 7 is a diagram showing another operation example of the system of the present invention. This operation example shows a case where, for example, one item of the demograph is selected in step AS10 waiting for the next operation (step AS11). Then, in step AS3a, the program-related data of the program By corresponding to the selected demograph item is used. Information on the device that viewed program B is searched. For example, when an age group (M1 or M2 or M3 or M4) is specified as an item in the demograph, the viewing-related data of devices having the selected user age group are collected, The number of devices will be analyzed.

In addition, the viewing-related data includes identification data such as whether the program was viewed live, recorded and then played back and viewed, or reserved for viewing. attribute), it is also possible to narrow down the viewing-related data to be used. In other words, it is easily possible to narrow down the attributes of the viewing-related data based on the demograph and make the program the subject of investigation.

Furthermore, in the embodiment of FIG. 4, co-channel program areas 332, 333 are used. However, the system allows the program area 333 to obtain other channels, ie the number of overlapping devices between different channels, and rankings. In such a case, it is also possible to compare programs with low audience ratings in one's own station and programs with high audience ratings in other stations in the same time slot. Therefore, in this case, it is preferable to prepare a selection box for selecting channels to be compared in the display area 331 .

Moreover, this system has a high utility value for program advertisement, and can of course be used for commercial product advertisement. In other words, among multiple channels, it is possible to decide to conduct commercial advertisements for programs (high-ranking programs) that are considered to have a large number of duplicate viewing devices in the combination of the first channel and the second channel. Become.
