Hereinafter, an example of an embodiment of the present invention will be described.
FIG. 1 is a block diagram illustrating a functional configuration of a management server 1 as an evaluation apparatus according to the present embodiment.

  The management server 1 is an information processing apparatus (computer) including a control unit 11 that controls the entire apparatus and a storage unit 12 that stores various programs and data. The management server 1 includes a communication control unit for communicating with an external device via a network, and may further include various input / output devices.

The control unit 11 executes a predetermined program (evaluation program) stored in the storage unit 12 to thereby execute an application providing unit 111, an annotation holding unit 112, a history management unit 113, a contribution point calculation unit 114, and a weighting management unit 115. Function as.
The storage unit 12 stores the annotation data 121 and the weighting table 122 in addition to the evaluation program.

The application providing unit 111 provides an application that receives an annotation input from a user as a viewer to a user terminal (such as a television or a mobile terminal).
This application may be described in HTML5 or the like that operates on a Hybridcast (registered trademark) television, but is not limited to this. For example, the application is described in various broadcast languages such as BML (Broadcast Markup Language) for data broadcasting or smart TV. May be.
The application may be installed in advance on the user's terminal.

The annotation holding unit 112 acquires the annotation input by the user for the video content, and stores the annotation history in the storage unit 12 as annotation data 121 for each user ID.
Here, the annotation type may include, for example, text, text with a link, text with a still image file, text with a moving image file, text with an audio file, and the like.

FIG. 2 is a diagram illustrating the annotation data according to the present embodiment.
An annotation has a start time and an end time, and is added to a scene in a program (video content). This example shows annotations added to four scenes.

The stored annotation data is encoded as tabular data. As the encoding format, a CSV format, a binary table format defined in the ARIB standard STD-B24 for data broadcasting, a JSON format used in Hybridcast, etc. can be adopted.
Note that four types of annotations are exemplified: T: text, LT: text with link, ST: text with still image file, MT: text with moving image file, but the number of types is limited to this. Absent.

  The history management unit 113 extracts annotation data for each user from the annotation data 121, and calculates the appearance frequency for each type of annotation.

The contribution point calculation unit 114 uses the weighting table 122 to calculate contribution points for each user by weighting based on the annotation type and appearance frequency.
Further, the contribution point calculation unit may perform weighting based on the amount of annotation information. For example, the importance may be given for each annotation according to the data capacity.

The weighting management unit 115 retains in the storage unit 12 a weighting table 122 that defines the annotation type for contribution point calculation and the weighting value for each appearance frequency, and provides it to the contribution point calculation unit 114.
In addition, the weighting management unit 115 updates the weighting table 122 based on the administrator's input.

FIG. 3 is a diagram illustrating a weighting table according to the present embodiment.
In the weighting table, for each annotation type and appearance frequency level, a weighting value for determining a score to be given per annotation is defined.
Here, the appearance frequency level is represented by the number of annotations input by the same user within a counting range such as for each program, for each scene in the program, for each series of continuous programs.

Even with the same annotation type, the weighting value may differ depending on the appearance frequency level. For example, it is set so that the weight of each annotation increases as more annotations are added to the video content.
The weighting table can be appropriately replaced by a service provider such as a broadcasting station. For example, each program may be replaced or a plurality of tables may be provided. By changing the weight, the motivation for the annotation input to the user is adjusted for each type.

FIG. 4 is a diagram illustrating a calculation example of contribution points according to the present embodiment.
The table in the figure shows the number (appearance frequency N) for each annotation type extracted from annotation data input by the user for a certain video content.
In this example, for the video content, the user performs 15 times for each type of text (T), text with link (LT), text with still image file (ST), and text with moving image file (MT). Annotation is input five times, three times, and twice.

  For the weighting for each annotation type, referring to the weighting table 122 in FIG. 3, weighting W (T) = 1 for text (T), weighting W (LT) = 2 for text with link (LT), text with still image file Weighting W (ST) = 10 for (ST) and weighting W (MT) = 20 for text with moving image file (MT).

  The contribution point is calculated as the sum of values obtained by multiplying the appearance frequency and the weight for each annotation type, and N (T) × W (T) + N (LT) × W (LT) + N (ST) × W (ST) + N (MT) × W (MT) = 15 × 1 + 5 × 2 + 3 × 10 + 2 × 20 = 95.

  Note that this calculation method is an example, and other calculation formulas based on the type and frequency may be adopted. For example, the appearance frequency N may be replaced with the sum of the weight values based on the information amount of the annotation.

FIG. 5 is a block diagram illustrating a first configuration example of a system including the management server 1 according to the present embodiment.
In this example, the user views the video content on the hybrid cast-compatible television 2a and inputs an annotation with the remote control 3 of the television 2a.

In this case, the television 2a is connected to the management server 1 via a network.
The management server 1 provides an application to the television 2a. When the user inputs an annotation to the application using the remote controller 3 as an input device, the annotation data is transmitted together with the user ID from the television 2a to the management server 1.

FIG. 6 is a diagram illustrating an example of an application screen on the television 2a according to the present embodiment.
An annotation input field 22 is displayed together with the TV program display area 21, and a software keyboard 23 for inputting an annotation with the remote control 3 is displayed.
As an annotation input method, various methods such as voice recognition can be adopted in addition to key input of the remote controller 3.

FIG. 7 is a block diagram illustrating a second configuration example of the system including the management server 1 according to the present embodiment.
In this example, the user inputs an annotation on the mobile terminal 4 such as a smartphone or a tablet while viewing the video content on the television 2b that does not support hybrid casting.

In this case, the mobile terminal 4 is connected to the management server 1 via a network.
The management server 1 provides an application to the mobile terminal 4. When the user inputs an annotation to the application using the mobile terminal 4 as an input display device, the annotation data is transmitted from the mobile terminal 4 to the management server 1 together with the user ID.

  In these configuration examples, the annotation data may be temporarily cached in a user terminal such as the television 2a or the portable terminal 4 and transmitted to the management server 1 at a predetermined timing. As a result, when real-time performance is not important as in VOD viewing, the processing load is reduced without impairing convenience.

According to the present embodiment, the management server 1 aggregates annotation data for each user, and calculates contribution points for each user by weighting based on the annotation type and frequency. Therefore, the management server 1 can evaluate the degree of user contribution in order to give an appropriate reward corresponding to the work load to the user who has input the annotation.
As a result, motivation for the input work of the annotation is provided, and an increase in the number of annotations can be expected by participation of a large number of viewers, and the system can be operated continuously. In addition, the economic effect of promoting content viewing can be expected.

  In addition, it is assumed that a contribution point is returned to a user as rewards, such as a privilege on goods, goods, etc., for example, the system and application of return may be provided by the third party cooperated with a broadcasting station, for example.

  Moreover, since the management server 1 can provide an application for collecting annotations from the user to the user's terminal, the management server 1 encourages a large number of viewers to participate in the system, not limited to a terminal in which similar functions are installed in advance. be able to.

  The types of annotation include text, text with links, text with still image files, text with moving image files, text with audio files, and the like. The management server 1 can appropriately give contribution points according to the input work load for each of these various types.

  Further, the management server 1 weights each annotation based on the amount of information such as the data size, thereby evaluating each annotation in more detail and calculating an appropriate contribution point.
