Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention combines a device for conducting audience ratings of television broadcasting and a device for conducting market research to simultaneously conduct audience ratings and market research. This relates to a device that has been used.

(Prior art) Measuring audience ratings for television broadcasts, etc. involves installing a channel detector in each home of the person being surveyed to detect the television channel being watched, and storing data from this channel detector. The system uses a method in which channel data accumulated through daily polling from a data center is collected at the center via a telephone line, and then analyzed by a computer to calculate audience ratings. The present applicant also proposed such a television audience rating measuring device in Japanese Patent Laid-Open No. 54-80617.

On the other hand, for market research, two methods are generally used: one using research paper and the other method of picking up data electronically. Regarding the methods of using survey forms, there are two methods for distributing and collecting the survey forms, such as having the researcher visit each home or workplace in person, or sending them by mail. This method has the advantage of being able to arbitrarily select the subject and scope of the survey, and can be changed at any time, but has the disadvantage that it takes time and effort to distribute and collect information, and that it is easy to make errors in reading the entered information. There is.

The method of picking up data by electrical means is
A research terminal is placed in the home of the person being surveyed, data is inputted, and this data is sent to a research center where it is analyzed by a computer. A common method for inputting data is to have a barcode reader read the barcode attached to the product, and input data such as the number of purchases and the price using a keyboard.

At this time, in order to reduce input errors, there is an example in which a method is used in which input methods, precautions, confirmation methods, etc. are displayed on a display, and the input is performed step by step. In order to send data to the research center, it was common practice to collect the recorded tapes or disks by mail or directly by the researcher, but recently data has been sent using telephone lines. Ta. This method has the advantage of dramatically shortening the survey time compared to methods using survey forms.

On the other hand, POS system (Point of 5ales)
Type 5 system) uses a barcode reader and keyboard to enter sales product data at each branch store such as a supermarket, sends it to the head office in real time, and analyzes it on a computer to understand sales performance, inventory management, etc. Although the purpose is different from market research, the collected data can be used for market research purposes.

(Problems to be Solved by the Invention) As mentioned above, conventionally, television audience rating measurement and market research have been conducted completely separately, and therefore, when both are performed electrically, each target is It is necessary to separately install a television audience rating measurement device and a market research device at the researcher's home, which has the drawback of requiring time and effort for installation and increasing equipment costs. Furthermore, since the audience rating survey and the market survey are conducted separately, there is no correlation between them, and there is a drawback that it is not possible to provide sufficiently valid data for survey analysis.

The first object of the present invention is to facilitate installation by conducting television audience ratings research and market research in common;
Moreover, it is an object of the present invention to provide a device with low equipment cost.

A second object of the present invention is to provide an apparatus that can combine market research and audience rating research to conduct more effective market research by utilizing the above-mentioned apparatus.

Furthermore, the third object of the present invention is to open up a new direction in market research methods using television broadcasting, to develop several effective terminal devices, and to utilize these terminal devices.
The objective is to provide a modern research device that can measure advertising effectiveness in real time.

(Means for solving the problem) The applicant has disclosed the above-mentioned Japanese Patent Laid-Open Publication No. 54
-80617, JP-A-54-8061 featuring a data transmission method from a channel sensor to a data processing device
No. 0 "Data transmission method using commercial power distribution lines" and JP-A-54-10607 "Subscriber telephone sharing device" which features a device for sharing one subscriber telephone line between a subscriber telephone and a terminal device. Patent applications have been filed for each. All of these techniques form the basis of the present invention, but the details will be referred to these publications and the main points will be described here.

As mentioned in the prior art section, audience rating and market research is carried out by installing a data input device and a data processing device in the home of the person being surveyed, sending the devices to a center, and using a computer to calculate the required data. Take. In the present invention, separate data input devices are provided for audience ratings and market research, but the data processing device is shared, thereby making equipment economical. At the center, the data is calculated by computer, so by changing the program it is possible to handle the calculation of audience ratings and market research data.

To detect channels while watching television, two methods are generally used: one is to pick up the leakage radio waves from the local oscillator of the television receiver, and the other is to detect and compare the audio intermediate frequency, but the former method is reliable. Therefore, this method is adopted in the embodiment of the present invention. Data transmission from the channel detector to the data processing device is performed through commercial power wiring, eliminating the need for wiring.

Market research uses a market research data input device that includes a barcode reader, a keyboard, and a display.The barcode reader reads the barcode of the purchased product, and the keyboard inputs the quantity, price, and other information. The keyboard may be of a push-button type, a soft-touch type, or a method in which a bar code of numbers or symbols is written on the top of the casing or the like and read by a bar code reader may be used. The data from the market research data input device to the data processing device may be transmitted using the above-mentioned commercial power supply wiring, or may be transmitted using a cable. Another method of market research is to provide individual research devices. This is done by pressing the corresponding key on the questionnaire transmitter equipped with the keyboard and other necessary keys while looking at the television screen, in response to the call from the screen.
The data is sent to a receiver by infrared rays, and from the receiver to a data processing device. Furthermore, instead of prompting from the screen, data may be input using materials distributed in advance. By providing this device,
Customers can input the quality of products and other items by age, for example, and send that data immediately to the center, which can then output the results in real time.

In the data processing device, data from each channel detector, individual audience rating survey device, market research data input device, and questionnaire survey device is identified, processed into a predetermined format, and stored in a memory. This data is sent to the center via a subscriber telephone line, which is shared with the subscriber telephone owned by the surveyee's home.

This data is normally sent to the center by polling within a limited time such as late at night or early in the morning, but if necessary, it can be sent from the center or from the surveyee's home at any time.

At the center, the interface is connected to a computer via a diameter, and the computer performs polling through the IJ port, sends data from the surveyee's home, and analyzes this to calculate the required audience rating or market research data. .

This scanning is performed via the control voltage generator 188 under the control of the CPU 150. The picked up signal is amplified by an amplifier 189, detected by an FM detector 190, converted into an original signal by a decoder 191, and accessed to the common bus 151. These input signals are added to the data stored in the ROM 152, time data, and data from each encoder, and are sent to the CPU 1.
The data is processed into data in a predetermined format under the control of 50 and stored in RAM 153. real time clock 16
8 outputs the current time of each data generation, and each device timer 169 also outputs the time used in each device. The home number encoder 171 outputs the number of the surveyed person's house, and the receiver number encoder 172 outputs the number of the corresponding receiver. Circuit 173 controls the scanning of eight receivers. The keyboard 174 is used to manually stop and start circuit operations, set the access time from the data center (to be described later), and connect to the subscriber telephone line. Since each data is all created by an interrupt, the circuit 170 controls the interrupt, and the terminal 175 connects a checker created to check the circuit operation.
and an interface 176.

The data format may be designed using a known method, taking into consideration specifications such as the required information and its amount, future expandability, required transmission speed, measures against power outages and failures, and control over transmission. In this embodiment, 16 codes (0-F) each consisting of 4 bits (0-F) are used, and information and control items to be transmitted are assigned to each code. For example, the fifth code is assigned to channel data and questionnaire data transmitted via a commercial power distribution line. Figure 15 illustrates this content.
A code number is assigned to the 0 character, and external input signals of data 46 to 49 in FIG. 2 are assigned to the 1 to 4 characters. Currently, only questionnaire data is input, so 0 is displayed for 1.2 characters. 5～
The B character is assigned a time of occurrence, which is Friday 15th.
The time is 55 minutes and 5 seconds.

Channel numbers are assigned to the C and D characters, and receiver numbers are assigned to the E and F characters, indicating that the number 1 receiver is receiving the first channel. Other codes are constructed using similar methods depending on the content of the data. Data for each of these codes is created each time new data, events, or controls occur or are performed. For example, regarding the channel data of the 5th code,
Every time you switch in, switch off, or change channels,
The first code, power outage occurrence time, is created each time a power outage occurs. The data created in this way is transferred to the data center within a predetermined time or whenever necessary.

In this case, the code shown in FIG. 16 is placed in the first line of the data. Code number 4 indicates the start of data collection, and characters 1 and 2 are F.

Add an F. The tenant number to be investigated is placed in the C-F character.

The data processing device 8 has a function of sharing the telephone line 154 with the subscriber telephone 155 at the subscriber's home.

In order to cause as little inconvenience as possible to the home of the person being investigated, data transfer is generally carried out during a designated time late at night or early in the morning, but the system also has the ability to make calls on its own if necessary. . The subscriber telephone 155 and the telephone line 154 are connected to the NCU via the switching type 1!158 used during the test.
(Network Control Unit: network control circuit). The NCU is controlled by an NCU control circuit 167, and when a call arrives within a predetermined time, it identifies whether the call is from the data center or a third party based on the presence or absence of a 2100Hz signal sent from the data center 10, and When receiving a call from a person, the ringback tone transmitter 164 sends out a ringback tone and notifies the family member of the incoming call. In response to this, the householder manually switches the telephone key 158 to the telephone side. When receiving a call from the data center, the device accesses the main body of the device and performs data transmission according to a predetermined routine. When calling the center outside of the designated hours, it is checked whether the subscriber telephone is busy or not, and if it is not busy, after waiting for a prepause time, if the telephone is a rotary telephone, the automatic dialing circuit 166 calls the telephone number. , DT for Butschhorn telephones
The data center 10 is called by the MF 165, and when the data center responds, data transmission is performed one by one, and when it is completed, the original state is restored. Data is sent via the communication interface 162, modem 161, and NCU 159.

(Effects of the Invention) As described above, according to the present invention, the audience rating research device and the market research device are integrated, which allows for extremely economical construction and easy installation. Moreover, not only can the audience rating of a broadcasted commercial be known, but also market research data for the product can be obtained extremely quickly. Traditional audience rating surveys only show how much of a commercial the surveyed people watched, but by adding the results of market research, they become interested in the commercial and have the desire to purchase it. Since it is possible to know the number of consumers who have actually taken the purchasing action, it is possible to grasp the degree to which the final purpose of the commercial has been achieved, and the effect is extremely large. Viewer rating surveys can now be used to determine the number of people who watched a particular channel, the composition of the personnel, and the ratings for each channel, based on the time spent tuning into a particular channel.

Furthermore, through questionnaire surveys, it is possible to investigate evaluations of commercials by family composition, age group, gender, etc. in near real time. This is something that has not been seen in conventional market research, and the effect is truly significant.
