Description

The present invention relates to a stream viewing analysis system that analyzes viewing during broadcast stream transmission that transmits streams via broadcasting.

Conventionally, as shown in Patent Document 1 below, this type of viewing history analysis system extracts a reference date based on weather data for a supply amount prediction device for gas supply, and calculates the actual hourly supply amount on the reference date. There are known methods that perform weather correction and day of the week correction on values.

Here, this supply amount prediction device detects whether a high audience rating TV program with a predetermined audience rating or higher is scheduled to be broadcast on the prediction target day, and if a high audience rating TV program is scheduled to be broadcast, , audience rating correction is performed on the predicted value of hourly supply amount after day of the week correction and weather correction.

In other words, when gas is supplied to each household, the impact of domestic hot water demand on the hourly supply is generally large. It is also known that, for example, when there is a high-viewership television program that is expected to have high audience ratings, the demand for domestic hot water decreases until the program ends as people refrain from taking baths, and that the demand for domestic hot water increases after the program ends. For this reason, it is necessary to reduce the hourly supply until the high-viewership television program ends, and to increase the hourly supply after the program ends.

In this way, conventional supply forecasting devices attempt to calculate the predicted value of the hourly supply with more accuracy by correcting the audience ratings when a high audience rating TV program is scheduled to be broadcast. be.

A stream viewing analysis system 1 according to the present embodiment is a stream viewing analysis system that analyzes viewer viewing in broadcast stream transmission that transmits a stream via broadcasting, and includes a social infrastructure status acquisition unit 10 and a home status acquisition unit. 20, a viewing status analysis section 30, a recommendation section 40, and a usage fee fluctuation processing section 50.

The social infrastructure status acquisition unit 10 acquires the usage status of some or all of the social infrastructure 100, mainly gas 101, water 102, electricity 103, and communication 104. For example, data may be acquired sequentially via the Internet from devices installed in these consumers or households that measure consumption amounts, or a social infrastructure information processing system (not shown) that collects data from these meters may be used. ) may be used to obtain the usage status sequentially.

The at-home status acquisition unit 20 acquires the at-home status of the viewer, whether the viewer is at home or absent (it may be the at-home rate or the waking-up home rate of a specific area or organization). Various methods can be adopted to obtain the home status. For example, the location information of the viewer's smartphone may be acquired from the communication infrastructure 104 or the like to determine the viewer's home status.

It may also be estimated based on the operating rate of the receiver 310 (the rate of whether the television is turned on), which will be described later. It can also be estimated based on the share of a certain channel among the TVs currently available. Note that instead of this, the information may be acquired by a determination unit of the receiver, which will be described later.

The relationship between the percentage of viewers at home and the amount of social infrastructure used by the household can be illustrated as shown in Figure 2. Generally speaking, as the percentage of viewers at home increases, the amount of social infrastructure used increases. (it becomes more obvious).

The receiver 310 includes a receiving section 311, a buffer section 312, a decoding section 313, a reproducing section 314, a determining section 315, a clock 316, a recording section 317, and a communication section 318.

The receiving unit 311 receives broadcast streams as an interface. In addition to reception, the receiving unit 311 also performs necessary processing such as demultiplexing if the transmitted broadcast stream data is multiplexed. As a result, a channel (for example, 101ch, etc.) is acquired.

The buffer section temporarily stores the broadcast stream data received by the receiving section 311. This enables stable decoding by the decoding unit 313, which will be described later, even if there is temporary data loss.

The decoding unit 313 performs a process of decoding the code of the information source such as video, audio, data, etc. encoded by the encoding unit of the TV broadcasting station 300. Note that during encoding, if encryption is being performed, the decryption unit 313 also executes necessary processing such as extraction of key information necessary for decryption.

The playback unit 314 performs playback processing of the video, audio, and data decoded by the decoding unit 313.

The determination unit 315 has a function as a so-called audience rating measurement device. That is, the stream played back by the playback unit 314 of the receiver 310 is identified and determined, and a so-called viewing history (viewing log) is generated.

Note that the determination unit 315 may be configured outside the receiver 310. For example, it may be a device that identifies and determines the stream played by the playback unit 34 of the receiver 310, such as a so-called audience rating measuring device.

Further, the determining unit 315 may have a function of identifying an individual viewing the stream in addition to identifying a reproduced stream. For example, in addition to identifying individuals and user IDs of users who are near the receiver 310 through short-range communication (communication via beacon with the user's smartphone), remote control input involves button operations to identify the user during remote control input. The configuration may be such that the information is received and the individual or user ID is specified. It is also possible to obtain the viewer's home status by receiving a remote control signal generated by the viewer's input operation. Generation and accumulation of the viewing history can be performed by user selection using remote control input or the like.

Moreover, the determination unit 315 can also measure the current value supplied to the receiver 310 by connecting or coupling with the power cable of the receiver 310. The determination unit 315 can obtain the operating status of the receiver 310, and even if it cannot necessarily obtain the TV viewing or video viewing status of the receiver 310, it can determine the difference from the screen OFF startup standby state based on the current value threshold. By determining the operating status of the viewer, it is possible to assume that the viewer is using the receiver 310 and to obtain the viewer's home status.

Furthermore, the determination unit 315 connects to a communication device such as an Internet router installed in the home, and monitors data packets communicated between the communication device and the Internet outside the home, thereby comparing the data packets when the viewer is not present. By detecting differences in flow rate and data packets viewed by Internet sites, it is also possible to obtain the viewer's home status. Furthermore, by determining the number and type of terminals connected to the Internet in the home, it is also possible to count the number of people at home.

Clock 316 is an internal clock of receiver 310.

The recording unit 317 records various information. For example, in addition to recording the channel information acquired by the receiving unit 311 and the video/audio/data reproduced by the reproducing unit 314 with the time of the internal clock measured by the clock 316, the determination result by the determining unit 315 is recorded. Remember viewing history.

The communication unit 318 is an interface for connection with an external server, etc. via a network, and has a security function, and is capable of, for example, transmitting information recorded in the recording unit 317 and acquiring data from an external server. ing.

The tally server 320 includes a tally section 321 and a storage section 322.

The aggregating section 321 and the accumulating section 322 aggregate the viewing history (including receiver ID, user ID, household ID, and viewing time) that is the determination result of the determining section 315 of the receiver 310, and store the aggregated viewing history in the accumulating section 322. Accumulate viewing history. For example, the aggregation server 320 can sequentially collect the viewing history (viewing log) from the communication unit 318 of the receiver 310, and can aggregate the operating rate (or occupancy rate, audience rating) as shown in FIG.

Note that the user ID is input into the receiver X by the user, and the household ID is issued for each household by the aggregation server 320 and assigned to the receiver X.

The aggregation unit 321 performs various analyses of viewing behavior, including viewer ratings. For example, as an analysis of viewing behavior, the aggregation unit 321 aggregates exposure to programs and exposure to advertisements by household, by user, and by receiver.

The home status acquisition unit 20 also acquires the use status of some or all of the gas 101, water 102, electricity 103, and communication 104 from the social infrastructure status acquisition unit 10, and determines whether the viewer is at home or not. The home status of the person may be acquired. For example, the consumer's home status can be obtained by acquiring the consumption amount from a device installed in the household that measures consumption amount, and determining the usage status based on the difference between the consumption amount threshold and the absentee status. You can also. Alternatively, the number of people at home may be determined by detecting discrete changes from trends in consumption.

The viewing status analysis unit 30 acquires and analyzes the viewer's viewing status.

Specifically, the viewing status analysis unit 30 collects a so-called viewing history (viewing log) generated by identifying and determining a stream played by a receiver 310 that receives a broadcast stream transmitted from a TV broadcasting station 300. Analyze the viewing status from the acquired viewing history (viewing log).

Note that the details of the analysis of the viewing situation by the viewing situation analysis section 30 will be described later.

The recommendation unit 40 provides various information based on the analysis results by the viewing status analysis unit 30.

Specifically, when it is estimated that the viewer is concentrating on viewing based on the analysis result by the viewing status analysis unit 30, the recommendation unit 40 recommends the event of the broadcast stream that the viewer is viewing and the broadcast stream. obtaining the timing of either or both of the content switching within the broadcast stream, and using the social infrastructure at the timing of either or both of the obtained event of the broadcast stream and the content switching within the broadcast stream; Recommends predictions of changes in the situation.

Note that the details of the recommendation by the recommendation section 40 will be described later.

The usage fee fluctuation processing unit 50 changes the usage fee of the social infrastructure based on the prediction of changes in the usage status of the social infrastructure by the recommendation unit 40. For example, if this change prediction predicts that the load or demand on social infrastructure will increase, usage fees may be changed to increase dynamically, creating the effect of dispersing user usage over time. If it is predicted that the load on social infrastructure will be reduced and demand will drop, it is also possible to dynamically reduce usage charges to users who have dispersed usage in return for their contributions.

The above is the configuration of the stream viewing analysis system of this embodiment. In the above configuration, each of the processing units of the social infrastructure status acquisition unit 10, the at-home status acquisition unit 20, the viewing status analysis unit 30, the recommendation unit 40, and the usage fee fluctuation processing unit 50 is, for example, It is composed of hardware such as a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory), and stores and holds programs that execute various processes described below in a memory (not shown). By executing it, it functions as an arithmetic device (sequencer) for executing various processes.

In addition, in the stream viewing analysis system of this embodiment, the social infrastructure status acquisition unit 10, the at-home status acquisition unit 20, the viewing status analysis unit 30, the recommendation unit 40, and the usage fee fluctuation processing unit 50 are configured within the same system (same server), but this is not limited to this, and some or all of these processing units 10 to 50 may be configured within another system (external server).

Next, details of the processing by the stream viewing analysis system 1, that is, the analysis of the viewing situation by the viewing situation analysis section 30 and the content of recommendations by the recommendation section 40 will be explained.

The viewing status analysis unit 30 (1) determines whether the usage status of the social infrastructure acquired by the social infrastructure status acquisition unit 10 has decreased with respect to the past usage status to be compared, and (2) (3) If the usage status of the viewer is decreasing, it is determined whether the viewer's home status acquired by the home status acquisition unit 20 is at home, and (3) if the viewer is at home, the viewing status analysis unit 30 acquires If the viewing status of the viewer indicates that the viewer is viewing a broadcast stream, it is estimated that the viewer is concentrating on viewing.

Here, the viewing status analysis unit 30 is not limited to analyzing the viewing status of an individual viewer, but may also analyze the viewing status of a household.
Specifically, based on the household ID assigned to the receiver 310, the viewing status of the receivers 310 having the same household ID can be analyzed to understand the viewing status of each household. In particular, if there are multiple viewers or multiple receivers in a household, the viewing status of multiple viewers and viewing status of multiple receivers can be aggregated even in one household. .

Furthermore, a population of viewers (instead of households) may be formed and the viewing status of the population may be analyzed. In this case, the population is defined by, for example, an area, and the aggregation server 320 samples the receivers belonging to the area as necessary, aggregates the viewing logs collected by the research panel, and calculates, for example, the TV viewership rate or usage rate. can be aggregated.

Here, the relationship between the percentage of viewers at home and the TV usage rate can be illustrated as shown in Figure 4. In general, the relationship is such that the TV usage rate increases as the percentage of viewers at home increases (this is more noticeable when the time of day is fixed). .

Furthermore, when viewers who are at home use TV more than usual, cases where they use TV less than usual are plotted as shown in FIG. 5. According to this, for example, when the TV usage rate is y = 20, the at-home rate would normally be z, but if the interest in TV is low, the at-home rate may be z2 (>z), If a person has a high interest in television, the at-home rate may be z1 (<z).
In addition, the relationship between the amount of social infrastructure usage and the at-home rate is plotted as shown in FIG. 6 when the amount of social infrastructure usage is larger than usual and when it is smaller than usual.

In this case, even if the amount of social infrastructure usage is v, the question is whether the at-home rate is w2 (>w), which is higher than usual and the usage is less, or w1 (<w), which is lower than usual and the usage is large. Since this is unknown, it is important to obtain the home-based rate in order to understand more details. In addition, by obtaining the at-home rate, it is possible to determine, for example, whether an increase or decrease in the TV usage rate is due to the at-home rate, or whether an increase or decrease in social infrastructure usage is due to the at-home rate. By analyzing the results, more detailed predictions can be made.

Social infrastructure usage status and home status can also be aggregated and analyzed for social infrastructure and viewers belonging to the area. The social infrastructure usage status, home status, and viewing status areas may be applied to the same area or to different areas.

For example, when predicting the usage status of social infrastructure in Area A, it is not only necessary to obtain the home status and viewing status of Area A, but also to obtain information on Area B that is different from, part of, includes, or spans Area A. Predictions may also be made by acquiring home status and viewing status. Similarly, the areas where the home status and viewing status are acquired may be different. This means that when predicting social infrastructure usage status in area A, even if the acquisition area for at-home status and viewing status is not fully or partially established in area A, the at-home status and viewing status can be substituted in other areas. This makes it possible to make predictions.

Then, when the viewing status analysis unit 30 estimates that the viewer is concentrating on viewing, the recommendation unit 40 recommends the event of the broadcast stream that the viewer is viewing and the content in the broadcast stream. The prediction of changes in social infrastructure usage at one or both of the timings of switching is recommended as follows. The information that is the source of this timing may be notified in advance of the timing from the information processing system of the TV broadcasting station 300 to the recommendation unit 40 within the broadcast stream or by another communication means.

For example, for water and gas, we predict the increase in usage at the end of a program as an event, the interruption or end of a broadcast game or program, or the timing of a commercial break as a change in content, and make recommendations accordingly. Provide information as content.

On the other hand, when people are concentrating on electricity and communications, the use of rooms other than the TV, living room, etc., and lighting are reduced (kitchens, toilets, baths, children's rooms, etc. are not used). Conversely, when a program ends as an event or a commercial begins as a content change (timing when concentration ends or is temporarily interrupted), viewers move on to other daily activities, the use of these rooms increases, and the room It predicts the increase in usage of lighting, electric stoves, electric water heaters, smartphone operations, etc., and provides information on this as recommendations.

In addition, the recommendation unit 40 notifies in advance the timing of one or both of an event in a broadcast stream and a change in content within the broadcast stream, which will trigger such a change.

Here, the recommended destinations (information provision destinations/broadcast destinations) by the recommendation section 40 include not only the provider of the social infrastructure 100 but also the relevant viewer, the TV broadcasting station 300, and the like. Further, the recommendation unit 40 may make various recommendations to advertisement purchasers and advertisement purchase applicants via an advertisement space trading system 330 that trades advertisements such as commercials. For example, the provider of the social infrastructure 100 that has received the recommended content can adjust the upper or lower limit of the amount of power generation or water supply, thereby reducing waste of resources.

In addition, the viewer may be notified in advance of the information that changes the usage fee for the social infrastructure processed by the usage fee fluctuation processing unit 50 as appropriate on the terminal etc. used by the viewer. This can be expected to decentralize the use of social infrastructure by users and reduce the burden of operating social infrastructure.

As described above, according to the stream viewing analysis system 1 of the present embodiment, when a broadcast stream is transmitted, it is possible to understand the actual viewing situation from multiple perspectives and appropriately understand it. This can be reflected in the prediction of changes in usage status, and the prediction information can be shared with related parties.

In this embodiment, a case has been described in which the application is applied to some or all of electricity, gas, water, and communications as social infrastructure, but the application is not limited to this, and may be applied to other social infrastructure such as railways. It may be applied to

Further, in this embodiment, a case has been described in which viewing status analysis is performed based on broadcasting, but the present invention is not limited to this, and viewer behavior can be analyzed using viewing history of IP streams in addition to or instead of broadcast streams. Analysis may be performed. Furthermore, VOD transmission may be used instead of IP transmission. Furthermore, the media is not limited to broadcast media, and may be audio media or web media.
