Description

System for monitoring advertisements from broadcasting data and method

The present invention relates to a broadcast advertisement monitoring system and a broadcast advertisement monitoring method, and more particularly, to a broadcast advertisement monitoring system and a broadcast advertisement monitoring method for monitoring broadcast data to identify an advertisement inserted into a broadcast.

Broadcasters produce and transmit broadcast content. At this time, the broadcaster inserts an advertisement of the advertiser into the broadcast data, and the advertisement fee of the advertiser is a main income source of the broadcaster.

Here, broadcast advertisements increase the profits of broadcasters, but excessive advertisements can harm the interests of broadcast viewers, and broadcasting is a kind of public service, which is appropriately sanctioned. Therefore, the advertisement inserted in the broadcast may be monitored by a broadcaster, an advertiser, an advertising agent (eg, Korea Broadcasting Corporation) and a civic group.

In general, the monitoring of broadcast advertisements is performed by the monitoring agent to monitor the advertisements by the naked eye or by hearing, to create a monitoring result or to automatically perform the monitoring using watermark technology. However, the way that monitors monitor advertisements with the naked eye or auditoryly requires a lot of manpower to monitor all the 24-hour broadcasting channels of various broadcasting companies (terrestrial broadcasting, cable broadcasting, IPTV, radio broadcasting, internet broadcasting, etc.).

In addition, the method using the watermark technology can automatically identify and monitor the advertisement, but due to the nature of the watermark technology, the watermark information inserted for each advertisement content is possible in the monitoring system. That is, a production company, a broadcasting station, or a Korea Broadcasting Advertising Corporation, as a subject, must insert and produce a watermark in the advertisement content, and since the watermark-inserted advertisement is inserted into the broadcast, the monitoring system uses the watermark from the broadcast data. Monitor your advertising. Here, if the Korean Broadcasting Advertising Corporation inserts a watermark into the advertisement content, monitoring of the advertisement is possible only by the Korea Broadcasting Advertising Corporation.

Therefore, only some operators (e.g., advertisers, broadcasters or Korea Broadcasting Corporation) that have the authority to create advertisements have a watermark embedded advertisement, and only those operators can monitor the advertisements using their own watermarks. have.

The present invention has been created under the recognition of the prior art as described above, and an object of the present invention is to create a schedule of broadcast advertisements and generate statistical information of advertisements by anyone monitoring advertisements of broadcast data using a fingerprint of advertisement contents. To provide a broadcast advertising monitoring system and a broadcast advertising monitoring method.

<1. System configuration>

1 is a schematic configuration diagram of a broadcast advertisement monitoring system 1 according to an embodiment of the present invention.

The broadcast advertisement monitoring system 1 according to an embodiment of the present invention is built on a wired or wireless network, and receives the broadcast data to monitor the broadcast terminal 2 for monitoring whether the advertisement content is inserted and to transmit broadcast data. It comprises a broadcasting station server (3).

The wired and wireless networks in the present invention typically correspond to wired, wireless broadcasting networks, satellite networks and the Internet, and encompass all communication networks capable of transmitting broadcast data using various protocols such as wireless public networks or dedicated networks.

The monitoring terminal 2 is installed in the monitoring program 200, and by executing the monitoring program 200, the monitoring terminal 2 monitors the data broadcast from the broadcasting station server 3 to determine whether to insert the advertisement In addition, the inserted advertisements are collected to generate a monitoring result.

The broadcasting station server 3 transmits broadcast data through wired and wireless networks. Here, the broadcast data may be audio data or video data and is not limited to a special data type.

2 is an exemplary diagram of a technical model of the broadcast advertisement monitoring system 1 according to an embodiment of the present invention.

The broadcast advertisement monitoring system 1 extracts at least one advertisement fingerprint by sampling every predetermined period from advertisement content data to be inserted into the broadcast. Here, since the advertisement content may be audio or video data, the fingerprint is an audio or video fingerprint corresponding to each.

When the fingerprint extraction is completed for each advertisement content, the broadcast advertisement monitoring system 1 extracts the broadcast fingerprint from real-time broadcast or locally stored broadcast data. The broadcast fingerprint is extracted from the broadcast data currently read.

When a broadcast fingerprint is extracted from the broadcast data, the broadcast advertisement monitoring system 1 performs a search for comparing the extracted broadcast fingerprint with a previously stored advertisement fingerprint. If it is determined that the comparison result satisfies a predetermined matching condition, it is determined that advertisement content corresponding to the advertisement fingerprint is inserted into the broadcast data. This enables advertising monitoring of broadcast data in real time without the intervention of monitoring personnel.

3 is a schematic internal structure diagram of the monitoring terminal 2 according to an embodiment of the present invention.

The monitoring program 200 of the monitoring terminal 2 according to an embodiment of the present invention includes an advertisement fingerprint extractor 21 for extracting a fingerprint from advertisement content, and an advertisement for indexing the extracted fingerprint by advertisement and location. The fingerprint indexer 22, a broadcast data storage unit 23 for receiving and storing broadcast data, a broadcast fingerprint extractor 24 for extracting a fingerprint from broadcast data in real time, a broadcast fingerprint and an advertisement fingerprint And a fingerprint comparator 25 for performing a comparison search and an advertisement insertion determiner 26 for determining that the advertisement of the advertisement fingerprint is an advertisement inserted into the broadcast.

The advertisement fingerprint extractor 21 extracts a fingerprint for each sample period set for at least one advertisement content to be inserted into broadcast data.

Here, the advertisement fingerprint extractor 21 extracts at least one fingerprint from among an audio fingerprint or a video fingerprint corresponding to the format of the advertisement content. In addition, since a part of the advertisement content may be inserted into the broadcast data, the advertisement fingerprint extractor 21 may extract the fingerprint from the advertisement content corresponding to the original data of the full length.

The advertisement fingerprint indexing unit 22 indexes the information identifying the advertisement with respect to the extracted fingerprint and stores the index in the DB. That is, in the present invention, the advertisement may be identified using index information of the fingerprint.

The broadcast data storage unit 23 receives data transmitted in real time and stores the data in a DB.

The broadcast fingerprint extractor 24 reads stored broadcast data to extract a fingerprint.

The fingerprint comparator 25 performs a search for comparing the broadcast fingerprint with the advertisement fingerprint.

Here, the fingerprint comparison unit 25 determines that the broadcast fingerprint and the advertisement fingerprint match when the predetermined comparison condition is satisfied. For example, when a predetermined threshold value is set and the coincidence value equal to or greater than the threshold value, both fingerprints are determined to match. In addition, when the predetermined time is set as the confidence interval and the coincidence degree is more than the predetermined threshold successively over the confidence interval, it is determined that the fingerprints of the two coincide. For example, a fingerprint of one side is continuously matched with a plurality of fingerprints of the other party, or a plurality of consecutive fingerprint sections of one side is corresponding to a plurality of fingerprint sections of the other party. In addition, various matching methods may be applied, and the present invention is not limited to a specific determination method.

When it is determined that the comparison search result matches, the advertisement insertion determining unit 26 determines that the advertisement content corresponding to the advertisement fingerprint is inserted in the broadcast.

For example, assuming that a 30 second advertisement is inserted into the broadcast data and broadcast data exists before and after the inserted advertisement, the comparison search fails in the broadcast data of the front end and for 30 seconds from the beginning of the 30 second advertisement. Comparative search results are successful. In the broadcast data of the latter stage after the 30 second advertisement ends, the comparison search result appears as a failure.

Here, the monitoring program 200 further includes an advertisement organizer 27 for generating an advertisement schedule using information of the inserted advertisement and an advertisement statistics unit 28 for generating advertisement statistics using the insertion information of the advertisement. It may include.

The advertisement organizer 27 generates an advertisement schedule such as program information, inserted advertisement information, advertisement time, and the like for each time zone and stores the advertisement schedule in a DB. In the advertisement schedule, broadcast channel information, time zone program information, and advertisement information are displayed. The advertisement organizer 27 displays an advertisement schedule on a screen at the request of a user, and provides a play time and order of advertisements inserted in a broadcast channel and a program for each time zone.

The advertisement statistics unit 27 analyzes and stores the statistics on the advertisements such as the number of times of advertisement appearance, advertisement play time, and inserted program information for each advertisement in each time zone and period.

When the statistics are generated, the advertisement statistics unit 27 may display statistics such as the number of advertisements by period, channel, and program of the advertisement A on the screen according to a user's inquiry request. The ranking list statistics of all advertisements may be provided on the screen.

<2. Method composition>

The broadcast advertisement monitoring method for monitoring an advertisement of a broadcast according to an embodiment of the present invention may be preferably realized through the construction of the broadcast advertisement monitoring system 1 described above.

4 is a flowchart for storing an advertisement fingerprint in a broadcast advertisement monitoring method according to an embodiment of the present invention.

First, in order to monitor an advertisement from broadcast data, a fingerprint DB for advertisement content should be constructed.

To this end, the monitoring terminal 2 reads the advertisement contents one by one by the execution of the monitoring program 200, and extracts a fingerprint every predetermined sample period from the advertisement contents (S21).

Then, the monitoring terminal 2 indexes information such as advertisement information and file position with respect to the extracted advertisement fingerprint and stores it in the DB (S22). The indexed advertisement fingerprint is compared with the fingerprint of broadcast data to determine whether an advertisement is inserted.

5 is a schematic flowchart of a broadcast advertisement monitoring method according to an embodiment of the present invention.

The monitoring terminal 2 receives and stores broadcast data transmitted in real time by the execution of the monitoring program 200 (S23).

Thereafter, the monitoring terminal 2 reads broadcast data in real time and extracts a fingerprint (S24).

When the broadcast fingerprint is extracted, the monitoring terminal 2 performs a search for comparing the broadcast fingerprint extracted in real time with the pre-stored advertisement fingerprint (S25). Here, the monitoring terminal 2 determines that the fingerprints match when the fingerprints of the two or more fingerprints are continuously matched by a predetermined threshold or more in the comparison search process.

If it is determined that successive matches during the predetermined confidence interval, the monitoring terminal 2 determines that an advertisement corresponding to the advertisement fingerprint is inserted into the current broadcast data (S26).

If it is determined that the advertisement is inserted, the monitoring terminal 2 generates and stores an advertisement schedule for each time zone using the program information and the advertisement information (S27). Of course, when monitoring the advertisement of the data broadcast in real time, the advertisement schedule is updated in real time when the fingerprints coincide with each other according to the comparison search result of the fingerprint.

In addition, the monitoring terminal 2 analyzes and stores the advertisement statistics information such as the number of times of advertisement, time of insertion, etc. for each time slot, period, and program for the inserted advertisement (S28).

In the above-described embodiment, the term "~ part" is not used as a term meaning a hardware division of the broadcast advertisement monitoring system. Therefore, a plurality of components may be integrated into one component, or one component may be divided into a plurality of components. In addition, the component may mean a hardware component, but may also mean a component of software. Therefore, it is to be understood that the present invention is not particularly limited by the term "part".

Although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains, and claims to be described below. Of course, various modifications and variations are possible within the scope of equivalents.
