- the storing of the fingerprint information for each advertisement by the association information manager 110 determines whether the advertisement stored in the association information manager 110 is being reproduced during broadcast by the advertisement information identification unit 120 described later. It is used to As will be described later, the advertisement information identification unit 120 continuously monitors broadcasts provided through a plurality of broadcast channels in real time, and prints fingerprint information by at least one of audio, video, or a combination thereof in real time. For example, it is possible to determine which one of the advertisements stored in the association information management unit 110 is broadcast by continuously extracting the data in a predetermined time unit and comparing the same with the fingerprint information stored in the association information management unit 110 as described above. have. Of course, other information besides fingerprint information may be used to determine whether an advertisement is being played during broadcast. However, as described above, fingerprint information clearly indicates unique characteristics of audio or video data. desirable.
- 3 is a diagram illustrating an example of association information and fingerprint information for each advertisement stored in the association information management unit 110.
- the advertisement field includes a brief description of each advertisement
- the advertisement identifier field includes an identifier uniquely assigned to each advertisement.
- the related information includes information such as "offer 5% discount coupon” and "link to www.ccc.com”.

- the advertisement information identification unit 120 indicates that the advertisement is started in real time when the advertisement is started during broadcasting. Since it is necessary to determine, it may be configured to include fingerprint information for the frame from the first frame of the advertisement to a frame within a certain period.
- the advertisement information identification unit 120 performs a function of identifying whether an advertisement stored in the related information management unit 110 is reproduced as described above during a broadcast provided through a broadcast channel. As described above, the advertisement information identification unit 120 continuously extracts fingerprint information by at least one of audio, video, or a combination of broadcasts provided through a broadcast channel in real time, and extracts the fingerprint information from the extracted fingerprint information. By comparing the fingerprint information for each advertisement previously stored in the association information management unit 110 may be made by a method of identifying whether the advertisement stored in the association information management unit 110 is played.
- the advertisement information identification unit 120 should determine whether the advertisement is played within a short time from the point of time when the advertisement is played, which is usually completed within a relatively short time such as 20 seconds, 30 seconds, 1 minute, and the like, which will be described later. This is because it is necessary to provide the association information to the client terminal 200 side and process the additional operation request based on the association information from the client terminal 200 side. Therefore, the advertisement information identification unit 120 preferably extracts fingerprint information of audio or video data of a broadcast screen for a relatively short section. If the advertisement information identification unit 120 determines that the advertisement is included in the screen broadcast in this manner, that is, the advertisement is being played, the advertisement information identification unit 120 notifies the association information sending unit 130 together with the information of the corresponding channel.
