Description

Survey system for television programs including dramas, comedies, sports, news, and commercials, etc in real time}

The present invention relates to a real-time broadcast exposure research system that can perform the survey, analysis, and output of the ratings of the television broadcast program in real time, and more specifically, the channel (drama, news, sports, advertising, etc.) selected by the viewer on the television. The present invention relates to a real-time broadcasting exposure research system that can receive information about the real-time broadcasting using a computer communication network, and can investigate, analyze, and output the current television audience with reliability and high accuracy.

Despite some claims that television is a fool's box, television has a great influence through the provision of information and entertainment throughout life, and various forms of utilization are being sought in connection with the Internet communication network. As television viewers are not only the target of the broadcast, but also the main target of marketing as the subject of product purchase, broadcasters can help to produce the viewer's favorite broadcast by investigating the viewer's reaction. There is an advantage in the development of products by investigating the ratings and responsiveness. Therefore, gathering the opinions of television viewers has emerged as a major challenge in modern marketing.

In particular, since it is a shortcut to product success that reflects the response of the viewers in a short time, preferably in real time to the company's product is a lot of efforts to obtain fast and accurate information.

For example, an advertisement broadcasted on a conventional television (see FIG. 1), a manufacturer develops a product after a preliminary examination of a desired product and product (step 1), and then asks an advertising company to produce an advertisement for the product. (Step 2). Advertisers (advertising agencies), commissioned by the advertiser (manufacturer) to produce advertisements in accordance with the concept of the product (step 3), and commissions the commercials to broadcast advertising construction (step 4). The Broadcasting Advertising Corporation organizes broadcast time zones to send out the commercials commissioned by each broadcasting station (step 5), and each broadcasting station broadcasts the advertisement produced by the advertisement producer through the airwave or cable according to the scheduled time (step 6). . When the advertisement is broadcast, the viewer can watch it through the television (step 7), and the advertisement production company or the manufacturer conducts a divisional advertisement exposure survey to investigate the exposure (viewing rate) of the commercial (step 8). Consumer responses collected by exposure surveys are later communicated to manufacturers for reference in product improvement and development. In addition to advertisements, viewer rating surveys of programs produced by broadcasting stations are also measured through surveys at the same time as viewing viewers in seven stages.

The exposure survey (viewing rate, etc.) of a program produced by a broadcaster such as a commercial commercial, a drama, a sitcom, and the like, refer to FIG. 2, and a production such as a commercial broadcast and / or a program broadcast by a television broadcasting station (hereinafter " After the airing of "broadcasting", a telephone survey method using a telephone in real time is mainly used. The telephone survey method is mainly to monitor the investigators set up to answer the telephone survey in advance, or to randomly call the program that they are currently watching and to record a report by recording an answer. have.

However, the above survey method has raised questions about the honesty of the viewers who respond, and since each investigator has to collect a survey and prepare a report for each field, after a long time after the broadcast, Problems such as receiving an effect are reported.

In other words, audience rating surveys on various broadcasts (news, dramas, entertainments) by various broadcasting companies (including public and cable stations) are being made using statistical data collected by telephone and monitor personnel from various research firms. . In this case, firstly, the survey time is unrealistic due to the difficulty of real-time survey according to the selection process of the survey time, and secondly, a large number of people survey a number of times when each broadcast is aired momentarily. The survey method is inefficient because a large number of people are needed. Third, the accuracy of the survey results is reduced due to errors in the input process because the data is inputted for the statistics of the survey results.

Accordingly, 1) the result of the questionnaire response may be large due to the change in the individual's situation according to the questionnaire response to the result. Is difficult to choose. 3) In particular, in case of live broadcasting (emergency broadcasting), securing such survey targets and questionnaire members and waiting for them at all times means that it is difficult to over-budget and regional selection. 4) Furthermore, regional characteristics such as election broadcasting are added. In the case of broadcasts, exposure surveys based on regional arrangements do not guarantee transparency.

The present invention has been made to solve the above problems, an object of the present invention is to receive information about the channel (drama, news, sports, advertising, etc.) selected by the viewer in real time using a computer communication network It is to provide a real-time broadcasting exposure research system that can investigate, analyze, and report the results of television ratings with reliability and high accuracy.

Another object of the present invention is to obtain accurate viewer rating information to ensure the advertiser's investment efficiency of advertising, and to provide a real-time broadcast exposure research system that broadcasters can reasonably calculate and impose advertising fees.

The real-time broadcast exposure investigation system of the present invention for achieving the above object, the channel detection unit 10 for detecting a channel signal selected by the viewer in the television (2), and the channel detected by the channel detection unit 10 A data transmission unit 20 for transmitting a signal, and a server 40 for receiving and processing the channel data signal transmitted from the data transmission unit 20.

According to another feature of the invention, the channel detecting unit 10 is connected to the tuner of the television channel input unit 101 for receiving a channel signal tuned by the viewer, and is input from the channel signal input unit 101 Modulation section 102 for recognizing a signal in a predetermined frequency band, and a signal output section 103 for outputting the signal output by the modulation section 102 to the data transmission section 20.

Hereinafter, the real-time broadcasting exposure investigation system of the present invention will be described in detail with reference to the accompanying drawings.

3 is a diagram showing a schematic configuration of a real-time broadcast exposure investigation system according to the present invention. This research system extracts data about a channel selected by a viewer (the channel of a broadcasting station currently being viewed) from a television set in a home, and transmits the data to a server to process the data in real time. In addition, by excluding the direct response of the viewer, which may lead to malicious error, it is possible to minimize the survey error due to no response or inappropriate response.

The real-time broadcasting exposure research system includes a channel detector 10 for detecting a channel signal selected by a viewer in the television 2, and a data transmitter for transmitting the channel signal detected by the channel detector 10 ( 20) and a server 40 for receiving and processing the channel data signal transmitted from the data transmission unit 20.

The channel detecting unit 10 detects a channel signal selected by the viewer from the television 2, and modulates the channel signal into a signal that can be recognized by the server 40 and outputs it. In other words, the channel detection unit 10 generates data for a broadcast station and a broadcast viewing time by using a frequency corresponding to the channel data output from the tuner of the television 2 and outputs the data to the data transmission unit 20.

The channel detection unit 10 can also install an on / off detection unit that automatically detects the television when it is turned on and operate the channel detection unit 10, or operate for 24 hours. desirable.

The identification of the broadcasting station channel that the viewer is currently watching may be performed using the following method. For example, suppose that the channel frequency data of channel 6 output from the tuner of TV is 6Mhz, the channel frequency data of channel 7 is 7Mhz, the channel frequency data of channel 9 is 9Mhz, and the channel frequency data of channel 11 is 11Mhz. If the sensing unit 10 detects the channel frequency data at 9Mhz, it recognizes it as channel 9. Accordingly, the channel detecting unit 10 may recognize that the channel currently broadcasted by the television 2 is channel 9. Since the frequency data for each channel can actually change the output value by a combination of circuits, it is important to maintain the output of different frequency signals for each channel.

In addition, the channel frequency detection unit 10 may be configured to detect the channel frequency by sampling (sampling) the TV 2 in an on state or at a predetermined cycle. The extraction period for the channel frequency can be accurately measured, for example, the broadcasted productions and commercials by setting the interval from 1 to 15 seconds. If the period is short (1 second interval), of course, there is a disadvantage in that the processing capacity in the server 40, but there is an advantage that can obtain accurate statistical results.

The channel detection unit 10 can also generate a unique ID, viewing time, and viewing channel data of the viewer (member) currently watching the television 2. Of course, if necessary, more viewer information can be included and provided. Such a function can be generated not only in the channel sensing section 10 but also in the data transmitting section 20 and will be described later. The channel data, the unique ID of the viewer (member), the viewing time, and the viewing channel data are collectively referred to as exposure information.

5 is a block diagram of an embodiment of the channel detection unit 10 described above.

As a first embodiment of the channel detecting unit 10, a channel signal input unit 101 for receiving a channel frequency from the television 2 and a channel frequency input from the channel signal input unit 101 are modulated to obtain channel data. A modulator 102 for extracting and adding exposure information such as a member (viewer) ID and viewing time data, and a data transmitter 20 to transmit the channel data output from the modulator 102 to the server 40. Signal output unit 103 for outputting to a computer (not shown). Alternatively, the signal output unit 103 has a built-in RS232C port for data transmission.

The current channel data of the television 2 detected by the channel sensing unit 10 is transmitted to the server 40 through the data transmitting unit 20. The data transmission unit 20 includes a communication device, and in particular, it is preferable to transmit data using the Internet communication network 30. Specific embodiments of the data transmission unit 20 will be described later.

The server 40 receives the channel data transmitted from the data transmission unit 20 through the internet communication network 30 and stores it for each member. The stored member channel data is output in a report form after the necessary data is extracted by an application program installed in the server 40.

The report output from the server 40 (or the screen output service from the server) is changed according to the application program, and the real-time data is based on the region's viewer rating, the viewer's rating by time zone, and the region's viewer rating by "broadcasting station" for "specific broadcasts". For example, it can be a time-of-view ratio. In addition, the statistical data may include seasonal ratings, regional ratings, time-of-view ratings, and seasonal ratings, regional ratings, and rating-time ratings for "specific broadcasts." Such statistical data can be processed into required forms and displayed via the Internet.

As a second embodiment of the channel detecting unit 10, a channel signal input unit 101 for receiving a channel frequency from the television 2 and a channel frequency inputted from the channel signal input unit 101 are modulated and channel data. And a signal output unit 103 for outputting the channel data output from the modulator 102 to a computer (not shown) of the data transmission unit 20 so as to transmit the channel data output from the modulator 102 to the server 40. ) Is included. In this case, the computer 201 used as the control unit of the data transmission unit 20 may be configured to add exposure information such as a member (viewer) ID and viewing time data. In fact, the data addition function is controlled programmatically, so it can be performed without any hardware change.

The difference between the first and second embodiments of the channel sensing unit 10 is whether or not the modulator 102 generates data different from the channel data. In the former case, all the necessary data are generated by the modulator 102. In the latter case, only the channel data is generated by the modulator 102, and the remaining data is generated by the data transmitter 20. FIG. Such a structure has the advantage of giving flexibility to be configured in a convenient manner in the manufacture of the advertising device of the present invention. In the first embodiment, the member ID is input directly to the channel detecting unit 10, and in the second embodiment, the member ID can be input through a computer control program.

4 is a configuration diagram of the real-time broadcast exposure investigation system of the present invention described above.

The computer 201 and the ADSL modem 202 are connected to the channel detecting unit 10. The computer 201 and the ADSL modem 202 are essentially the same as the data transmission unit 20 of FIG. 3, and the computer 201 transmits data by the channel detection unit 10 and the data communication line (RS232C standard). Receive.

The computer 201 transmits data input through the RS232C port to the server 40 through the ADSL modem 202 connected to the Internet communication network 30. The data transmission unit 20 may be configured using a communication device capable of connecting to the Internet communication network 30 such as the BSL 203 or the cable modem 204 as well as the ADSL modem 202. The computer 201 is provided with a program for temporarily storing channel data input through the channel detecting unit 10 and transmitting the temporary data to the server 40 through the Internet communication network 30.

Since ADSL, cable modem, etc. are well-known high-speed Internet services, explanations are omitted. BNA (B & A) is a service that uses a telephone and high-speed Internet at the same time by installing a high-speed Internet subscriber terminal device in an internal telephone line such as an apartment, officetel, or building.

The broadcast exposure data including the channel data input to the server 40 is processed by the control unit 401 of the server 40. That is, the controller 401 operates the application program module 402 to process the input broadcast exposure data. The control unit 401 also stores data according to the member information through the Internet communication network 30 and calculates statistical values. The member information is stored in the member information DB 403 connected to the server 40, and ehgks the statistics for each content that requires it to be stored in the member statistics DB 404.

To calculate the statistics, the server 40 stores the contents of the broadcast of the television program. This is data about a name, a broadcast time, etc. of a program published in a newspaper or broadcasted by a broadcasting station, and such statistics can be used to extract statistics on channels and broadcasts currently viewed by viewers.

In addition, data generated in real time as needed, such as region-specific viewing rates for broadcasting stations, time-of-view viewers, regional viewership for the broadcast (advertisement, drama, news, sports, etc.), time-of-view viewerships, etc. The stored data is stored in the real-time transmission DB 405 to transmit the data.

In addition, the extracted data using the various functions supported by the application program module 402 is stored in the broadcast statistics DB (406). The above-described DBs are stored in storage devices such as hard disks, magneto-optical disks, tape drives, and the like.

The application program module 402 can be used as a program, a database program designed to receive and store data and extract necessary information. For example, a database program may be configured using a Microsoft commercial database program or a commercial commercial database program such as Oracle's Oracle8i.

The server 40 can also add a firewall and mail server 50 as needed. The firewall is to prevent hacking of the server 40 from the outside, the mail server 50 is to enable the viewer (member) to notify the viewer of the viewer's unique viewing history. Herein, the member means a viewer who connects the channel sensing unit 10 to the television 2 and provides a member ID to provide television viewing information. Each member is assigned a unique member ID.

The member ID is stored in the channel detector 10 so that the member ID and the channel data are automatically transmitted to the server 40 (corresponding to the first embodiment of the modulator 102 of the channel detector 10). Storing the member ID in the channel detection unit 10 is input to the ROM in which the program is stored.

However, in the second embodiment of the modulation unit 102 of the channel detection unit 10 of the present invention, the member ID and other necessary information are not stored in the computer of the data transmission unit 20 without storing the member ID or the like in the channel detection unit 10. To generate the data. In the second embodiment, the channel detecting unit 10 simply extracts only the channel data, and generates and transmits the member ID and other exposure information from the computer of the data transmitting unit 20.

The operational effects of the real-time broadcast exposure investigation system as described above will be described with reference to the flowcharts of FIGS. 6 and 7. 6 is a description of the acquisition process of the channel data, Figure 7 is a description of the processing of the acquired channel data.

When the television is turned on by the viewer (member), the channel sensing unit 10 is also turned on. The on / off operation of the channel sensing unit 10 is also installed in the channel sensing unit 10, and the on / off switch is also turned on manually or kept on for 24 hours at all times. Alternatively, an on / off control detector may be added to detect the on state of the television 2 and automatically turn on the channel detector 10.

After the channel sensing unit 10 is turned on, the channel sensing unit 10 receives channel frequency data for the channel selected by the viewer from the television 2. The channel frequency data may be input from a tuner of the television, and the channel detecting unit 10 may extract channel data currently tuned by the television 2 using the input channel frequency data.

The broadcast exposure data including the channel data generated by the channel detector 10 is transmitted from the data transmitter 20 to the server 40 through the internet communication network 30. The server 40 processes broadcast exposure information input from each viewer (identified by member ID) using a built-in application program.

In addition, the server 40 may readjust the transmission period of the broadcast exposure information. That is, when the transmission period (T) data is transmitted from the server 40 to the data transmission unit 20 through the Internet communication network 30 corresponding to the time corresponding to the transmission period in the computer 201 of the data transmission unit 20 The data is sent to the server 40. The transmission period T can be adjusted at intervals of 1 to 15 seconds, and preferably at intervals of 10 seconds. The setting of the transmission period (T) to 10 seconds is to take into account the commercial time, in order to ensure the accuracy of the statistics of the viewer rating of the commercial, which is usually about 15 to 30 seconds.

When the transmission of the broadcast exposure information from the data transmission unit 20 is completed, the server 40 may extract necessary statistics by using the transmitted data. For example, after broadcasting exposure information data input to the server 40 is sorted by content, stored by broadcasting stations, or stored by time zone, the data is extracted for each service using a function supported by the application program module 402. do. The extracted data is stored in the DB for each service. At this time, the information for data extraction is information on the name and broadcasting time of the television broadcast program input by the operator.

For example, the member information is stored in the member information DB 403 connected to the server 40, and data generated in real time, for example, region-specific viewing rates for broadcasting stations, time-of-view rates, and broadcasts (advertisements, dramas) Data generated in real time, such as local viewer ratings, hourly viewer ratings, and the like, are stored in the real-time transmission DB 405. In addition, the extracted data using the various functions supported by the application program module 402 is stored in the broadcast statistics DB (406).

Data processed by the application program module 402 may be serviced through the monitor screen of the server 40. As an example of the screen configuration, the region-specific viewer rating, the viewer rating by time zone, and the "viewing by broadcasting station" may be the viewer rating by region and viewer rating by time zone for "specific broadcasts." In addition, the statistical data may include seasonal ratings, regional ratings, time-of-view ratings, and seasonal ratings, regional ratings, and rating-time ratings for "specific broadcasts." Such data may of course be inputted and output to the application program module 402 of the server 40. The extracted data as described above may be displayed in a web page format or may be read in a DB to advertisers requesting a television advertisement through the Internet.

8 is a configuration example of the above-described broadcast exposure information.

Member ID is AAA001, English letter means region code and number means member unique number. Therefore, AAA001 can be seen as the first member of the region marked AAA. In addition, the time indicates the time when the broadcast exposure information was extracted (sampled). The broadcast channel means a channel selected at the time when broadcast exposure information is extracted from the television 2, and the broadcast code is a mark indicating a specific broadcast or commercial broadcast. The broadcast code can be recognized using the G code currently provided by the television broadcasting station. The normal presence is a code for confirming whether or not the television 2 is in a normal operating state. The broadcast exposure information as described above may provide various data by changing contents.

As described above, according to the present invention, information about a channel (drama, news, sports, advertisement, etc.) selected by the viewer on TV is received in real time using a wired / wireless computer communication network to investigate the current television rating with reliability and high accuracy. By acquiring accurate viewership information, advertisers can be assured of advertising's return on investment, and broadcasters have the advantage of being able to rationalize their advertising fees.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
