Description

Description Program evaluation device, program evaluation data totaling device, program evaluation method, and recording medium

The present invention relates to a technology for utilizing viewer evaluation data for contents of a broadcast program, and relates to a broadcast receiving device, a broadcast transmitting device, a broadcast program creation, and the like. Background art

· · · Prior art · · ·

(Evaluation of products by consumers)

For ordinary hardware products, consumer evaluations are fed back to manufacturers, which is the driving force behind better products. For example, merchandise sales data from merchandise stores (so-called POS data) also express consumer evaluations. In addition, evaluations by periodicals such as “Living Notebook”, “Specialty Town”, and “Sure Eyes” issued by the Kokumin Seikatsu Center prevent people who are going to buy products from purchasing bad products. This has been a trigger for improvement and improvement by manufacturers. And that brings out consumer satisfaction. (Evaluation of broadcast programs)

On the other hand, broadcast program contents are provided to viewers by program producers via broadcast stations. Assuming that the program creator is the mainstay of the product called content, the viewer is the consumer of the product. The evaluation of a content product called a broadcast program is judged by the only index called “viewing rate”.

Here, there is “movie” as a product similar to broadcast program content, but in the case of movie, there is an ex post evaluation of box office revenue, and there is also evaluation by mass media such as movie critics and magazines. However, there are indicators that are quite objective. However, in the case of broadcast program content, there is no critic or other evaluation system.

Guidebooks of television programs can also serve as critiques that can be consulted before viewing. Many. But such reviews are not very useful. The reason is that it cannot be commented on because it is a real-time media. Also, unlike a movie, a broadcast program may be too numerous to be carefully reviewed. As more broadcasting channels are added in the future, it is not expected that more careful reviews will be made than ever. Also, except for NHK (Japan Broadcasting Corporation), programs have sponsors, so there is also a problem that it is difficult to give negative or critical evaluations to programs. Furthermore, there is no concept of “sales, box office” other than some pay broadcasts.

(Appearance of hard disk recorder)

By the way, in recent years, the viewing of broadcast programs is not limited to real-time viewing due to the development of recording devices. In particular, in recent years, with the progress of hard disk-related technology and the sudden increase in capacity and price, the “hard disk recorder (HDDR)” has been put into practical use. The hard disk recorder is a television capable of recording broadcast programs on a hard disk instead of a video tape, and is also called a “personal video recorder (PVR)”. With the widespread use of hard disk recorders, it is certain that the percentage of people who record without watching them while they are being broadcast (real time) and watch them later will increase.

Hereinafter, the best mode of the program evaluation data totaling device according to the present invention will be described with reference to FIGS.

(Overview)

As shown in FIG. 1, in the present embodiment, a viewer who has watched program content provided by a broadcasting station evaluates a program and accumulates evaluation data in a database center. This is a system that allows a user to view a program after referring to it. In addition, evaluation data can be provided to a program production company for reference in the next program production.

(Relationship between broadcasters and viewers)

As shown in Fig. 1, a broadcasting station provides program content to viewers through a broadcasting facility for broadcasting the broadcast program content. Viewers are broadly classified into a type of viewing content in real time (viewer A in FIG. 1) and a type of recording content once and viewing the content (viewer B in FIG. 1). Viewer A needs a TV receiver as a broadcast receiving function and a TV monitor as a content output function. Viewer B also needs a hard disk recorder to record and save content. A personal computer with a television function may be used.

(Input of evaluation data)

Viewer A who has watched the program content inputs evaluation data for the content and attribute data of viewer A using an evaluation data terminal device as shown in FIG.

This evaluation data terminal device is a device that only evaluates a program, which is physically independent of a device that receives and plays back program content. This is a device for transmitting input data to a database center. Figure 6 shows the image.

The operation includes a cursor key, a select button, a cancel button, a send button, and the like. Other keys may be provided as needed. In addition, a liquid crystal panel is also provided, and the liquid crystal panel is provided with a display for designating an item to be input.

The two questions shown on the LCD panel in Fig. 6 are part of the viewer's attribute data. Attribute data has a relationship with the evaluation entity of the evaluation data, and will be described later. Although illustration is omitted, evaluation data is input after attribute data is input.

The input data is temporarily stored in RAM and transmitted via a public telephone line. (Function of evaluation data terminal device)

The above-described evaluation data terminal device has the following functions.

The first is an output detection function that detects that program content has been output. Specifically, as shown in FIG. 2 and the like, the fact that the program has been output is detected by being electrically connected to the television receiver. This function is used to ensure that evaluation data is input when viewing program content, and is useful for efficient collection of evaluation data. Some output detection functions can acquire program identification data such as broadcast date and time, broadcast station and program name. The program identification data is obtained by reading the digital watermark embedded in the data of the program contents. Next is the function to promote the input of attribute data and evaluation data. This is achieved by software that outputs questions to the liquid crystal panel of the terminal device. These output displays may be provided by a ROM pre-embedded as a chip in the terminal device, may be transmitted from the database center every time, or may be periodically rewritten by the database center. It may be. In the case of each transmission and periodic rewriting, a rewritable storage device is required for instruction data of items to be input.

Next is the function of inputting attribute data and evaluation data. These are achieved by the input keys of the terminal device. It is naturally possible to use an input device using a liquid crystal touch panel without using the input keys as shown in FIG.

Next is the function of transmitting data such as attribute data and evaluation data input by this terminal device. This function is achieved by the modem and communication software.

The evaluation data terminal device may have an automatic input mechanism that functions when the viewer does not actively input. For example, “〇 or 視聴” may be automatically input when the program content has been viewed to the end, or “△ or X” may be automatically input if the program content has not been viewed to the end.

(Evaluation data)

Evaluation data is sent for each evaluation of the evaluation subject (Ms. A and B). However, it is also possible to transmit data collectively at predetermined time intervals.

Fig. 4 shows an example in which the transmitted evaluation data is output for each evaluation subject. In Fig. 4, for convenience of expression, the horizontal axis represents the time. In reality, the evaluation data is for each program name.

Mr. A is a real-time viewer, as shown in Figure 1, but evaluates multiple channels at the same time because he changed channels during the program.

As shown in Fig. 4 and Fig. 6, the evaluation was made in three stages: "〇: good", "△: fair", and "X: good". However, the steps may be more detailed or two steps. Furthermore, a separate keyboard or the like may be used, or a keyboard may be displayed on the liquid crystal, so that the evaluation by the document can be input and transmitted.

(Refer to other people's evaluation data)

As shown by viewer B in Fig. 1, program content is recorded, evaluation data of another person is obtained, then the program to be viewed is selected with reference to the evaluation data, and only the selected program is viewed. The case will be described.

As shown in Fig. 3, viewer B has a hard disk recorder that records program content, hardware that has the function of obtaining evaluation data of others and then outputting the evaluation data. Software is provided. That is, a request transmitting means (a reference evaluation data request function) for transmitting to the database center that the user wants to refer to the evaluation data of another person, and the database center receives the request from the request transmitting means and transmits the evaluation data of the other person to the database center. The data receiving means for receiving the evaluation data when transmitted (reference evaluation data receiving function) and the output means for outputting the received data (reference evaluation data output function) obtain the evaluation data of another person. Therefore, the evaluation data is referred to.

In the request transmission means, it is possible to input selection conditions for evaluation data to be referred to. The “selection condition” is, for example, if the employee is a male employee in his 20's, the attribute data “20's male employee” is used as the selecting condition. Furthermore, when there are many evaluation data that meet the selection conditions, it is possible to narrow down by another selection condition, or to select 10 people for the time being.

If there is no input of selection conditions, the database center automatically selects them. For example, as shown in Fig. 5, “people who have a high matching rate between themselves and the evaluation” are ranked and transmitted at the database center. A high match rate means that preferences can be expected to be similar. It should be noted that it is naturally possible to narrow down the conditions by appropriately combining the tastes and attributes, or to loosen the conditions.

In Fig. 5, the perfect match is counted as “+2 points”, “〇 and △” and “△ and X” are counted as “+1 point”, and the perfect mismatch is counted as “1 or 2 points”. Are ranked in order of height. Then, the evaluation data of the top five is sent to Mr. B. The first output of the transmitted data is the match rate and attributes in rank order. Clicking on any one of the five allows the clicked person to view the evaluated data. Mr. A who refers to any or all of the five people will use it as a reference to decide which of the recorded programs to watch.

(Provision of the program)

In order for the hard disk recorder used by the viewer to have the functions described above, a program is required. The program sends the broadcast program An output detection procedure for detecting that the content has been output, an evaluation data input promotion procedure for prompting the viewer to input the evaluation data of the content, and transmitting the input evaluation data to the database center. This is a program for executing a transmission procedure. In addition, the program includes an attribute input facilitation procedure that prompts the viewer to enter viewer attribute data. A computer-readable recording medium storing this program will be distributed to viewers for free or for a fee.

(First database center)

The database center has a data reception function for receiving attribute data and evaluation data, an evaluation database and attribute database for storing such data, a data calculation function for sorting and calculating data, and evaluation of others. Request reception function to receive a request to refer to data, reference data calculation function to calculate which evaluation data to send back in response to the request, and reference data transmission to send reference data extracted by calculation It has functions and so on.

In the present embodiment, the initial registration is made to have the attribute data input and transmitted, and the program evaluation which can refer to the evaluation data of another person is required on condition that at least one evaluation data is input and transmitted. It is a data aggregation device. Therefore, viewers cannot refer to the evaluation data entered and transmitted by other people unless they send their own attribute data and evaluation data based on their own judgment.

The following are definitions and doubts about unclear words and terms. However, their incompleteness does not narrow the scope of the present invention.

(About "One program")

Usually, “one program” is counted as one program with a program title specified by the broadcasting station.

In the case of commercial broadcasting, one program is determined by detecting a 1 Z 60-second interval provided between commercials or commercials.

In addition, if the program title is viewed as one program, if the sponsors of the program are grouped because the program is a long-time program, one program may be included in each sponsor group. Note that it is possible to define “one program” depending on the convenience of the broadcasting station or program production company. (About "One evaluation")

In principle, one evaluation is made for one "" three programs. However, if we strictly adhere to the principle that a program cannot be evaluated unless it is viewed from the beginning to the end, there is a problem that it is difficult to collect evaluation data because it does not conform to the actual situation. Therefore, it is possible to input evaluation data even when viewing a program from the middle or halfway through the program.

(Evaluation entity of evaluation data)

There is a problem of who inputs the evaluation data. For example, instead of having one program output device per person, if multiple people watch a program simultaneously using one program output device, who is involved in the attribute data to be input along with the evaluation data? What is that?

As a general rule, the person who inputs and transmits the evaluation data inputs and transmits the evaluation data as evaluation data accompanied by their own attributes. However, for the purpose of simplifying the collection of evaluation data, it is possible to divide as follows.

First, there is a method of unifying the attribute data of the representative who inputs the evaluation data most. In addition, there is a method in which the attribute data itself is input as household characteristics. For example, a household is a unit of attribute data, such as a couple in their 40s and two children of elementary school students.

There is also a method of providing a family button on the evaluation data input terminal device. For example, it is necessary to select a family button such as “father” or “child” as a condition for inputting evaluation data.
