Description

TECHNICAL FIELD [0001] The present invention relates to a method and an apparatus for measuring TV ratings using near-ultrasound communication or a real-time T-commerce interworking method and apparatus.

The following description relates to a method and apparatus for investigating audience ratings through television and personal video devices using near-ultrasound communication. The present invention also relates to a method and apparatus for real-time linking with a T-Commerce application of a broadcasting program and a smart device provided in a television.

In order to investigate the TV audience rating, the audience rating research company designates the appropriate number of sample viewers to provide the People Meter device. As the sample viewers watch the TV using the People Meter, they periodically transmit the channel they are watching to the audience rating company using telephone and other communication methods. The rating agency investigates the audience rating by program or channel based on the data sent by the sample viewers.

In recent years, technology using smart phones that almost all citizens have has emerged in order to overcome the disadvantages such as incapability of accommodating a channel with many devices called People Meter, inconvenience of management, and disadvantages of continuously paying fixed telephone costs. The term smartphone refers to mobile phones such as Apple's iPhone, Samsung's Galaxy, and Blackberry, which use Google's Android and Apple's iOS as operating systems. Most TV viewers typically watch their TV and put their smartphones within a short distance. Viewership research using smartphones has the advantage that it is very accurate and convenient because it can clearly distinguish user age and sex characteristics and location information. In particular, audience rating research using smart phones does not have to provide a People Meter, and Wi-Fi or data services can be used to save money compared to ordinary landline phones.

How to investigate the rating using smartphone is as follows. First of all, when the user activates the viewer application on the smartphone and watches the TV, the sound from the TV can be received by the smartphone through the voice microphone or the speaker mounted on the smartphone. The audience rating research application on the smartphone extracts the time and frequency feature points of the received sound (Feature Detection) and transmits it to the rating agency. A technology for extracting such feature points is called Audio Finger Printing technology, and a variety of techniques have recently been announced. The audience rating company uses Audio Finger Print to compare the Audio Finger Print received from the smartphone with the Audio Finger Print of the broadcast channels currently being broadcast and analyzes what channel the viewer is currently watching I will. If the number of channels is less than five, it is known that these techniques operate sufficiently in real time. However, if the number of real-time channels is between 200 and 500, the complexity of Audio Finger Print Matching will increase significantly. Although domestic pay-TVs provide 200 real-time broadcasts, US pay-TVs currently provide more than 500 real-time channels. There is an inconvenience that one Audio Finger Print must be matched with all channels broadcast in real time.

In addition, in recent years, in view of the surge of broadcasting programs through VoD (Video on Demand), research on program rating through VoD has become more important over time, and it is urgent to acquire related technologies. VoD is a system in which a video program such as a movie provided in the past or present in a real time broadcasting channel or provided in the past or present theater is transmitted through a pay broadcast system such as cable TV, IPTV, satellite TV, mobile IPTV, Is a video that is sold according to. Accordingly, the number of VoD programs generally reaches tens of thousands and is increasing day by day. Though limiting the audience rating survey to terrestrial broadcasting programs, it will be easy to go through thousands. Of course, even if it is reduced to a program broadcasted within the last week, it will reach hundreds of times. Moreover, unlike real-time broadcast, VoD starts from time to time according to the demand of viewers, so that the complexity of the audio fingerprint matching method can not be increased.

SUMMARY OF THE INVENTION The present invention is directed to a television viewing rate research method.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

Ultrasound means a frequency that the human ear can not hear, and a near-ultrasound means a sound wave that can hardly hear the ear. For example, you can hardly hear sounds above 18,000 Hz except people 10 years and older. If the frequency exceeds 10,000 Hz, the reception level drops significantly from 2,000 Hz to 4,000 Hz, which is the best frequency for humans to hear. When the frequency exceeds 18,000 Hz, 30 to 40 dB is attenuated. .

When the unique identification information about the broadcast program is transmitted to the audio frequency band of 18,000 Hz or higher or the surrounding area, the microphone of the terminal (for example, smart phone, smart TV, etc.) receives the program identification information Can be extracted. The extracted information is sent to the rating agency to provide the viewer with a view of the program they are watching without complicated Audio Finger Matching process.

As described above, according to the present invention, unique identification information of a broadcast program is transmitted to a terminal together with a broadcast program on the basis of Near Ultrasound Communication to provide an audience rating without using a People Meter required for a conventional audience rating survey, The present invention proposes a method for enabling a T-Commerce application and a broadcast program to be automatically linked to each other even if a viewer changes a channel by providing T-Commerce through a terminal.

1 is a diagram illustrating an example of a network environment according to an exemplary embodiment.

The T-commerce application server 111 detects a broadcast program or a channel output from the output device 120 based on specific information and provides the terminal 110 with a T-commerce page of a broadcast program or channel .

FIG. 2 is a diagram for explaining an operation of a broadcast program information providing apparatus according to an embodiment.

The smartphone 210 can receive the identification data of the broadcast program from the audio region of the broadcast program output from the output device 230 through the near ultrasound band. At this time, the smartphone may exist at a predetermined distance from the viewer who watches the broadcast program, for example, within 1 meter, near the viewer.

The broadcast program information providing server may mix identification data for identifying a broadcast program in an audio area of the broadcast program. At this time, the mixing of the identification data can be performed at the beginning of the broadcast program, at a certain period, and occasionally as needed, non-periodically. Such repeated transmission allows the viewer to switch the channel from time to time, and can watch the VoD program, so that it can be provided to judge whether or not the program is viewed even in the middle of watching the program. In addition, the broadcasting program information providing server may mix the identification data for identifying the broadcasting program in the audio area of the broadcasting program, and may further include a step of attenuating the audio area likely to be collided with the near-ultrasound band using a high-pass filter or a band- Can be removed. The broadcast program information providing server mixes the identification data of the broadcast program in the audio area of the broadcast program using near-ultrasound communication, and outputs the mixed data through the speaker of the output device. The broadcast program information providing server may transmit the identification data output through the speaker of the output device 230 to the smartphone 210. [

The broadcast program information providing server can modulate the data frame for the identification data into the near ultrasound band. The broadcasting program information providing server can perform a wave shaping in which the user does not have irritation in the ear or a digital modulation method such as ASK (Amplitude Shift Keying), PSK (Phase Shift Keying) or FSK (Frequency Shift Keying) It can be modulated to near-ultrasound in a frequency band that can not be used. Also, the VoD can be applied in the same manner as the broadcasting program. The broadcast program information providing server may transmit the broadcast program and the identification data for the broadcast program to the output device so that the output device outputs the broadcast program.

The viewer 240 who has committed to conduct the audience rating survey with the audience rating company can install the audience rating survey application on the smartphone 210. [ At this time, the viewer 240 may refer to a viewer who watches a broadcast program. The smartphone 210 can demodulate the identification data of the broadcast program modulated in the near ultrasound portion. At this time, the smartphone 210 may perform a process of correcting an error check on the identification data. The smartphone 210 can transmit the identification data of the acquired broadcast program to a rating research server connected to the rating agency through wireless communication, for example, Wi-Fi or a data channel. For example, the smartphone 210 can transmit identification information of the broadcast program, reception time, information on the viewer, and the like to the audience rating investigation server. More specifically, the smartphone 210 may transmit data to the audience rating survey server via data communication with the viewer's location, time, age, gender, or other viewer data. The audience rating survey server can determine the audience rating based on the identification data received from the smartphone 210. [

When the viewer 240 watches the broadcast program, the smartphone 210 detects the broadcast program or channel being output from the output device from the data frame according to the demodulation of the identification data of the broadcast program, And can be automatically switched to the tee-commerce page of information or channel related to the broadcast program.

In this case, even when the interlocked tee-commerce application is operated, the application recognizes the corresponding program, channel information, or Web address transmitted through the near ultrasound and automatically links the application so that the viewer can continuously maintain the interoperability even when the channel is changed Let's do it. At this time, in the case of a real-time broadcast-oriented service, since the number of channels is not much as compared with the case of providing VoD, it can be performed using the conventional Audio Finger Print technology.

For example, the smartphone 210 extracts feature information related to a broadcast program being output from an output device from a data frame using an audio fingerprinting technique, transfers the extracted feature information to a te-commerce application server, It is possible to switch to the broadcast program or channel being output from the output device based on the feature information. As T-commerce application server has conventionally made T-commerce in the TV data broadcasting system, the software of the TV or set-top box is not flexible and it is difficult to carry out complicated process to settle the payment with TV remote controller. The terminal 110 performs a tee-commerce process in order to solve the problem that has not occurred. At this time, when the viewer switches the channel or the output device is driven for the first time, it can be used to automatically recognize the broadcast program provided by the smart phone and automatically connect the te-commerce application. The smartphone 210 may be switched to the T-commerce page of the information or channel related to the broadcast program in association with the detected broadcast program or channel.

A program corresponding to a broadcast program provided in real time or an application linked to a channel can be operated by a viewer on a smart phone so that a viewer can purchase various products appearing in a program provided in the broadcast through an application linked thereto.

The broadcast program information providing server mixes the identification data of the broadcast program in the audio area of the broadcast program using near-ultrasound communication, and outputs the mixed data through the speaker of the output device. The broadcast program information providing server may transmit the identification data output through the speaker of the output device to the smartphone.

In step 520, the broadcast program information providing server may modulate the data frame for the identification data into the near ultrasound band. The broadcasting program information providing server can perform a wave shaping in which the user does not have irritation in the ear or a digital modulation method such as ASK (Amplitude Shift Keying), PSK (Phase Shift Keying) or FSK (Frequency Shift Keying) It can be modulated to near-ultrasound in a frequency band that can not be used. In addition, the broadcasting program can be applied not only to terrestrial broadcasting and cable broadcasting but also to VoD in the same manner as a broadcasting program.

In step 530, the broadcast program information providing server may transmit the broadcast program and the identification data for the broadcast program to output the broadcast program on the output device.

6 is a flowchart illustrating a method of providing audience rating information in a broadcast program information providing apparatus according to an exemplary embodiment of the present invention.

The broadcast program information providing apparatus may mean a terminal, and a smart phone will be described as an example. An application for recognizing a data frame according to the identification data of the broadcast program and transmitting it to the audience rating investigation server may be installed in the smartphone and operated.

In step 610, the smartphone may receive the identification data of the broadcast program from the audio region of the broadcast program output from the output device through the near-ultrasound band.

In step 620, the smartphone may demodulate the identification data of the broadcast program modulated with the broadcast program.

In step 630, the smartphone may transmit the identification information of the broadcast program and the identification information of the viewer to the audience rating investigation server based on the data frame according to the demodulation of the identification data of the broadcast program. At this time, the smartphone can transmit the identification information of the broadcast program, the reception time, and information on the viewer to the audience rating investigation server. For example, the smartphone may transmit data to the rating system research server via data communication with the viewer's location, time, age, gender, or other viewer data.

According to one embodiment, it is not necessary to use the People Meter necessary for the existing rating survey. Therefore, it is troublesome to manage thousands of people or tens of thousands of viewers in order to make the statistics of the People Meter difficult to handle, and it is troublesome to manage them constantly. .

In addition, in order to extract Audio Finger Print from a smart phone, a signal processing algorithm having a very high complexity must be operated in a smartphone, which can solve the problem that a considerable burden is imposed on a smartphone. In addition, the extracted Audio Finger Print can be transmitted to an audience rating server to periodically match with several hundreds of real-time broadcasting Audio Finger Prints to detect the channel received by the viewer, thereby solving the problem of the calculation amount burden.

 In addition, recently, VoD ratings have become very important. Since the number of VoD programs is actually tens of thousands and can be watched at any time, the number of programs that must be matched in real time increases from hundreds to tens of thousands It is possible to reduce the server cost that the audience rating company must purchase.

According to the embodiment, the program identification data is transmitted by near-ultrasound without changing the basic frame of the existing smartphone-based rating system, and the smartphone receives the program identification data. Thus, even if the number of programs increases, Because it does not use the Print Match method, it does not raise the computational complexity. Therefore, the calculation burden on the smartphone will be small and the cost of the rating server will be significantly reduced.
