In particular, the present invention relates to a digital broadcasting system for collecting and using usage information of various viewers such as viewing channel information and viewing time of a user watching a data broadcasting. An information collection system and a method thereof.

Recently, as digital TV broadcasting is in full swing, interest in data broadcasting services using data is increasing. Digital broadcasting has been able to provide various services, including interactive services, which have not been possible by transmitting data in addition to audio and video.

All broadcasts such as terrestrial, satellite, and cable will be digitized in the next 10 years, and according to such changes, all environments will be shifted around the medium of TV, not only broadcasters but also content providers, advertisers and consumers.

Thanks to the technological advances in data broadcasting, broadcasting will provide more information and new fun, and the demands of viewers on these services will be more diversified.

Such data broadcast is basically loaded with the receiving terminal device to transmit the program data including the transmission of the broadcast, and such a program responds to the viewer's viewing of TV programs and commercials, so-called TCP / IP and others. It can be delivered through a 'return path' using a communication method.

Advertisers who want to increase their competitiveness through TV will also have to develop new advertising companies and content to meet the needs of these viewers. When all broadcasts are digitized, the role of advertisements including data and inducing viewers' participation in advertisements is a very important factor.

As described above, in the digital data broadcasting, data can be transmitted in addition to the existing audio and video, so that the viewer requests additional information about the product advertised separately from the progress of the broadcasting or on the spot while watching the commercial. It is also possible to purchase.

On the other hand, in the data broadcasting as described above, since an interactive relationship is possible, it is possible to collect various information such as viewer's viewing contents, viewing time, user information, etc. in addition to purchasing goods through advertisements.

Thus, for example, in public rating surveys and user information, only general manual broadcasting such as telephone or verbal surveys or limited collection of information using limited devices is available. It is possible to collect and process the information of the so-called customer relationship management (customer relationship management).

However, in order to collect such information, a formalized and unified protocol, a so-called protocol, is required, but such a protocol is not provided until now, and therefore, there are limitations in collecting and using such viewer information. .

4 is a diagram illustrating a process of processing a protocol when viewing a normal channel, FIG. 5 is a diagram showing a process of processing a protocol when viewing a data channel, and FIG. 6 is a diagram illustrating a tree structure of a data channel. Hereinafter, the operation and effects of the present invention will be described with reference to FIGS. 1 and 6.

For example, a case where a virtual viewer views two general channels CH100 and CH101 and one data independent channel will be described with reference to the accompanying drawings in which a protocol is processed according to the viewer's viewing pattern.

There are two normal channels (CH100, CH101) and one data independent channel. At about 9:20, as shown in Fig. 4, the viewer turns on the receiving terminal apparatus such as a set-top box or digital TV and starts watching Ch100.

Ch100's 9 o'clock news program ends and advertising starts. After the mobile phone advertisement, a pizza advertisement containing a data application with a promotion for ordering pizza in the advertisement is transmitted. Viewers watch data application advertisements in addition to audio and video advertisements, acquire information, and order pizza through authentication process.

According to the viewing activity of the viewer as described above, events A-1 to A-4 occur (advertising audio / video).

Thereafter, while watching the advertisement, the viewer switches the channel to CH101. In fact, the events generated according to the viewer's viewing activity as described above are usually generated by the protocol when the viewer switches channels.

However, as described above, the protocol may be created at the end of the application, at the end of the terminal, at the end of the set-top box, at the end of the abnormality, or at the click of the remote controller (input device).

While watching a music program on the CH101 channel, the application related to the audio / video is transmitted. Indicates an indication that the data application has been sent out on the screen (typically, a letter "D" or a corresponding mark is displayed in the corner of the screen).

The viewer launches the data application, browses the application and watches the desired information (events A-11 and A-12 occur: general audio / video + data linked service).

Thereafter, the program is terminated by the program schedule, and the viewer watches the new program and switches the channel to the data channel while watching. As described above, a collection protocol is automatically generated by the protocol collection program at this time. (B-1 and B-2: general audio / video)

In the Data channel, as shown in Figs. 5 and 6, a portal application for application category and ease of use is transmitted.

The viewer uses the transferred application to navigate to the game index page, which is the portal page for the category that they want to use.

Among Tetris, Go and shooting game applications, viewers choose a shooting game. (C-1 to C-7: Data standalone service)

The shooting game application is sent and loaded and the user uses the application. The viewer may include passing an authentication module other than the receiving terminal device's own authentication based on its ID and password.

As described above, the receiving terminal device such as a set-top box receives personal information and information on the page of the application used by the viewer from the collection server 300. Thereafter, the user plays the shooting game application, and when the play is over, saves the result. (D-1 to D-5)

The viewer changes the channel back to CH101 and transmits the collected protocol information and the result to the collection server 300 (E-1). Then watch the program and stop the system on your set-top box or digital TV.

In the above example, four service models are included.

1. General Audio / Video: Information gathering based on audience rating A type of information is collected.

2. Advertisement: Information gathering and promotion of viewer information consisting of advertising units Type A information is collected and the corresponding advertising application is collected in the form of B type

3. General Audio / Video + Data linked service: Information about the channel is collected in the form of A type, and the linked application is collected in the form of B type.

4. Data Standalone Service: Protocol information is collected for each data application. The information that is protocolized will vary depending on the configuration of the applications. Usually B-shaped form.

As described above, the present invention systematically classifies and collects events according to data broadcasting viewing activity of a viewer, and effectively transmits them by protocolizing them.

The above embodiment is an example for explaining the technical idea of the present invention in detail, and the scope of the present invention is not limited to the above drawings and embodiments.

As described above, the present invention is an invention having an effect of collecting and using usage information of various viewers such as viewing channel information, viewing time, etc. of a user watching data broadcasting.
