Description

System and its method for providing advertisement based on substance of multimedia contents

The present invention automatically compares the image, audio or video fingerprints extracted from the contents of the multimedia contents with the fingerprints of the multimedia contents that the advertiser wishes to insert, and automatically inserts the advertisement of the advertiser in the matching multimedia contents to the user. The present invention relates to an advertisement providing system based on contents of multimedia content, and an advertisement providing method thereof.

In the current multimedia content advertisement, when an advertiser sets an advertisement target (category, keyword, etc.), the content provider (hereinafter referred to as "business operator") inserts the advertisement into the multimedia content corresponding to the advertisement target and provides it to the user. .

In the above case, the operator compares the meta information (eg, category, title, keywords, etc.) of the multimedia content with the advertisement target of the advertiser, and inserts an advertisement in the multimedia content and provides the same to the user. However, the meta information input by the user may be inaccurate, so that the advertisement may be inserted into the multimedia content that matches the meta information of the content and the advertisement target of the advertiser but is completely different or less relevant. Since the advertisement is inserted into the multimedia content having a content completely different from the advertisement intention of the advertiser, there is a problem of lowering the advertisement effect and increasing the unilateral advertisement cost burden of the advertiser.

In addition, the advertiser wants to advertise in real time to the multimedia content that is currently high ranking by riding on the viewer ratings or popularity of the multimedia content fluctuating in real time without limiting the target to the specific target. However, there is a problem that the advertiser can not specify the multimedia content ranking changes in real time. This is because the contents and fields of multimedia contents varying in real time are so diverse that it is difficult to find common points that can specify all popular contents. That is, it is impossible for an advertiser to pre-register corresponding categories, titles, keywords, and the like by predicting popular multimedia contents in the present or near future.

Furthermore, in the current multimedia content service, the user is provided with the multimedia content service regardless of the author in a free sharing and infinite sharing environment. In this case, when the service provider inserts an advertisement into the content requested by the user and provides the advertisement, the content into which the advertisement is inserted may be luckily registered content or content registered by the user. If the service provider inserts an advertisement into the user's content, the advertising fee revenue generated from the advertiser is not distributed to the author but distributed to the user. In this service structure, there is a problem in that a dispute arises between a service provider and an author.

The present invention has been made in view of the foregoing, and compares whether the content of the multimedia content is the content of the multimedia content that the advertiser wants to advertise and automatically inserts an advertisement into the multimedia content of the content desired by the advertiser to provide the advertisement to the user. An object of the present invention is to provide an advertisement providing service based on multimedia contents.

In addition, when an advertiser inserts an advertisement into multimedia content having a desired content, an object of the present invention is to search for the copyright holder of the content and reward the corresponding copyright holder with the advertising revenue generated from the advertisement provision.

According to the advertisement providing system based on the contents of the multimedia content of the present invention for achieving the above object, to analyze the contents of the multimedia content on the wired and wireless network to insert the advertisement in the content desired by the advertiser to provide the advertisement to the user An advertisement providing system, comprising: means for receiving and storing advertisement criteria of content desired from an advertiser; Means for extracting, indexing and storing a first finger print of content corresponding to the advertising criteria; Means for extracting, indexing and storing a second finger print of the content provided to the user; Means for comparing the first finger print and the second finger print, and inserting an advertisement file registered by an advertiser in content provided to a user if the comparison results match; And means for transmitting the content in which the advertisement file is inserted in response to a user's request for providing the advertisement to the user based on the content of the content.

According to a preferred feature of the invention, the advertising criteria, the advertiser directly registered to request the insertion of the content; Viewer rating or popularity information registered by the advertiser to specify an advertisement target; And at least one of a content title and episode information registered by the advertiser to specify an advertisement target.

Furthermore, when the advertiser registers the viewership or popularity information as an advertisement criterion, the advertiser may further include means for searching for and storing content corresponding to the viewership or popularity in real time.

Furthermore, the finger print may include at least one of an image, audio or video finger print extracted from the content data.

Preferably, the content in which the advertisement file is inserted is a content generated by inserting an advertisement in real time according to a user's provision request or a content generated by inserting an advertisement in advance before the user's provision request.

Preferably, the first finger print is characterized in that it further comprises means for rewarding the creator of the extracted content from the advertising costs of the advertiser according to the reward rate.

Further, means for automatically detecting author information contained in the content to uniquely identify the author; And means for registering and storing copyright-set contents from the copyright holder, and storing corresponding copyright information when the fingerprint and the first finger print of the copyright holder contents are compared and matched.

Meanwhile, according to the advertisement providing method based on the content of the multimedia content of the present invention, the content of the multimedia content (hereinafter referred to as "content") on the wired and wireless network to analyze the content of the advertiser to insert the advertisement in the content desired by the advertiser to the user An advertisement providing method of an advertisement providing server, the method comprising: receiving and storing advertisement criteria of content desired for advertisement from an advertiser; (S22) extracting, indexing and storing a first finger print of content corresponding to the advertisement criterion; (S23) extracting, indexing and storing the second finger print of the content provided to the user; (S24) comparing the first finger print and the second finger print and inserting an advertisement file registered by an advertiser in content provided to a user when the comparison results match; And (S25) providing the advertisement to the user based on the content of the content, including transmitting the content in which the advertisement file is inserted in response to a request from the user.

The advertisement providing system and the advertisement providing method based on the contents of the multimedia contents according to the present invention compare the contents set by the advertiser to the advertisement target contents and the contents of the contents provided by the user, and when the contents have the same contents, Provide the inserted content to the user.

In addition, when the content of the advertisement set by the advertiser is secured by the advertiser and the content in which the advertisement is inserted is provided to the user, the corresponding author compensates a part of the advertising revenue.

Hereinafter, with reference to the accompanying drawings looks at in detail the configuration of a preferred embodiment of the present invention.

<1. System Configuration>

1 shows a schematic configuration of an advertisement providing system 1 according to the present invention.

In the advertisement providing system 1 according to the first embodiment of the present invention, an advertisement providing server 2 inserting an advertisement into content requested by a user in a wired / wireless network environment and an advertiser terminal 3 in which an advertiser registers an advertisement. , A user terminal 5 for uploading or downloading content by the user.

Meanwhile, the advertisement providing system 1 according to the second embodiment of the present invention further includes an author terminal 4 which registers copyright information in the above-described first embodiment. According to the second embodiment of the present invention, when providing the content in which the advertisement is inserted in the first embodiment, the author of the content is analyzed based on the content to compensate a part of the advertising revenue to the corresponding author.

In the present invention, the advertisement providing server 2 distributes the content in which an advertisement is inserted to a member or a non-member user by building a home page. Content in the present invention includes image, audio or video content as multimedia content. Furthermore, the contents of the contents are various fields such as education, finance, games, news, and entertainment, and are not limited to specific contents or specific data formats. In addition, in the present invention, the advertisement inserted into the content is not limited to a specific data format such as a text advertisement, an audio advertisement, a video advertisement, and the advertisement display format may be displayed to the user in various ways through the playback window or the pop-up window of the corresponding content.

The advertisement providing server 2 registers and stores the content from the first user and provides a search and distribution service of the content to the second user. Registration and provision of content may be provided for a fee or free according to a service policy. The advertisement providing server 2 analyzes the contents of the contents provided to the user and the contents of the contents desired to be inserted by the advertiser, and inserts an advertisement in the corresponding contents and provides the same to the users. That is, when an advertiser registers content of an advertisement target as an advertisement criterion, an advertiser inserts an advertisement into content that meets the advertisement criterion and provides the same to the user. For example, if an advertiser specifies song A and requests insertion of an ad file, the advertiser searches for all content that matches the audio data of song A (e.g., ringtones, MP3s, dramas with song A inserted as background music) Inserting advertisements into the retrieved content. As another example, when an advertiser applies for an advertisement by specifying a specific image B, the advertiser searches for image or video content in which the specific image B is inserted and inserts the advertisement in the content.

Preferably, the insertion time of the advertisement is inserted immediately before the corresponding content is transmitted in real time according to the request for providing the content of the user, or the content in which the advertisement is inserted in advance according to the advertisement period setting of the advertiser is prepared in advance and in accordance with the request of the user. to provide.

In order to insert an advertisement corresponding to the content content as described above, the present invention uses a finger print technology. The fingerprint used in the present invention is ID information for uniquely identifying the content by extracting the unique characteristic of the data. That is, the advertisement providing server 2 extracts and indexes and stores the first finger print from the content meeting the advertisement criteria of the advertiser, and extracts and indexes the second finger print from the content to be provided to the user. Then, a search comparing the first and second finger prints is performed to insert the advertisement file of the advertiser in the matching content and provide the same to the user. The insertion position of the advertisement file can be inserted anywhere in the content data. For example, if an advertiser sets some 15-second videos in a 120-minute running time movie as an advertisement criterion, it is possible to insert an advertisement at a matching 15-second video data position in the 120-minute film.

In the present invention, an image, audio and video fingerprint may be extracted according to the format of the content. For example, an image fingerprint may be extracted in the case of a picture, an audio fingerprint may be used in the case of music, and an image, audio, and a video fingerprint may be extracted in the case of a video such as a movie and a drama.

In the present invention, the fingerprint extraction is performed by dividing the original data of the content into units of a predetermined length or area, and extracting the characteristic of the corresponding area data and storing it as fingerprint information. For example, in the case of an image or a video fingerprint, the unit image frame of the content is divided into a matrix area of m x n to extract, index, and store the fingerprint from the unit area. The audio fingerprint restores the audio data from the content, divides the region into predetermined length blocks, extracts the index, and stores the fingerprint from the unit region. More detailed fingerprint extraction techniques are introduced in a number of Korean patent applications (Application Nos. 10-2007-47197, 10-2007-79844 et al.) In which the inventor Park Man-Soo of the present invention is listed as an inventor. It is also disclosed in "Frequency-Temporal Filtering for a Robust Audio Fingerprinting Scheme in Real-Noise Environments" (ETRI Journal, vol. 28, no.4, Aug. 2006, pp. 509-512). Therefore, all the contents related to the fingerprint extraction in the patent application and the paper can be integrated as part of the configuration of the present invention.

Preferably, in the present invention, the advertiser inputs the content in which the advertisement is to be inserted as an advertisement criterion. Advertisers can directly register content and request ads for all content that matches the content. In addition, the advertiser may set an audience rating or popularity for specifying content as an advertisement criterion. Here, the viewer rating or popularity must be specified so that it can be objectively determined. For example, an advertiser may register a URL of a particular web page that may refer to viewership or popularity. Alternatively, the advertisement providing server 2 may provide various reliable ratings or popularity materials to the advertiser to select. When the viewership or popularity is set as an advertisement criterion, the advertisement providing server 2 searches for the corresponding content and stores the content as the content requested by the advertiser. Therefore, whenever the viewer rating or popularity ranking changes, the corresponding content is searched in real time or periodically, and the advertisement can be provided to the user after the advertisement is inserted in the content corresponding to the found content. In addition, when the advertiser registers the title of the content as an advertisement criterion to specify the content, the advertisement providing server 2 searches for the corresponding content. For example, when an advertiser registers 11 episodes of drama A, the advertisement providing server 2 searches for the 11th program of the corresponding drama, and secures the content of the advertisement target. The first finger print is extracted from the content registered directly by the advertiser or the content automatically searched by the advertisement providing server 2 in accordance with the advertisement criteria of the advertiser.

In the second preferred embodiment of the present invention, whenever the advertisement providing server 2 provides the user with the inserted content, the author of the content is compensated for the advertisement. Therefore, when the content is determined that meets the advertiser's advertising criteria, the corresponding author information should be stored. To this end, author information is automatically extracted by analyzing content of advertisers. Here, the author information may be information that is encrypted (eg, watermarked) and continuously inserted in the content data so as not to disturb the user's perception, or may be information perceived by the user because it exists in the content. For example, by extracting an author logo (movie company, broadcaster, record label, company, etc.) or author name included in the content, the author information is automatically detected. Alternatively, the fingerprint is extracted by registering the content file from the author, and the extracted fingerprint is compared with the first finger print to search for the author information.

Meanwhile, in FIG. 1, although the advertisement providing server 2 illustrates the construction of an advertisement insertion function, a content providing function, and the like as a single server, the advertisement providing server 2 may be configured as a distributed server through appropriate design changes. For example, the advertisement providing server 2 may be configured to have only an advertisement insertion function, receive content from the existing general content distribution server 2, and insert a corresponding advertisement to respond. Furthermore, in the second embodiment, the content corresponding to the advertisement criteria of the advertiser may be transmitted to an external server and then the corresponding author information may be received.

2 and 3 show the structure of the advertisement providing server 2 according to the first and second embodiments of the present invention.

Referring to FIG. 2, the advertisement providing server 2 according to the first exemplary embodiment of the present invention registers and stores advertisement criteria including content, viewer ratings, and popularity from an advertiser, and stores the advertisement criteria, the viewer rating, Content retrieval means 211 for retrieving and storing corresponding content when the popularity is an advertisement criterion, first finger print extracting means 22 for extracting and indexing the first finger print from the desired content of the advertiser, and for distribution by the user. Second-finger print extracting means 23 for extracting and indexing second-finger prints from the registered contents and ad-file inserting means for generating a content in which advertisements are inserted into the matching content by comparing and searching the first and second-finger prints with each other; And content transmitting means 25 for providing the user with the content inserted with the advertisement.

3, the advertisement providing server 2 according to the second preferred embodiment of the present invention is configured to automatically determine the author of the content corresponding to the advertisement criteria, in addition to the components of the first embodiment described above. An author information detecting means (221) for analyzing the content to detect and storing the author information, and constructing an author content DB to compare the fingerprint and the first finger print of the author content and store the corresponding author information if they match; Fingerprint retrieval means 222, and the author compensation means 26 for providing a user with the content inserted in the advertisement and then rewards the corresponding author to the advertising revenue in a certain ratio.

Detailed functions and operations of the individual components constituting the advertisement providing server 2 will be described through an advertisement providing method based on the contents of the multimedia content described below.

<2. How to Configure>

The advertisement providing system and the advertisement providing method based on the contents of the multimedia content according to an embodiment of the present invention can be preferably realized through the construction of the system 1 described above.

4 is a flowchart illustrating a method of providing an advertisement according to the first embodiment of the present invention.

According to the first embodiment of the present invention, when an advertiser registers an advertisement target and simultaneously registers an object to be inserted as an advertisement criterion, the first finger print extracted from the contents meeting the advertisement criteria and the content extracted from the contents provided to the user are provided. Compare the two-finger print and insert the ad into the matching content and provide it to the user.

First, the advertisement criteria registration means 21 of the advertisement providing server 2 registers and stores the advertisement criteria from the advertiser accessing the homepage (S21). In the process of registering an advertisement file, an advertiser registers a content target to which an advertisement file is to be inserted as an advertisement criterion. The advertisement criterion registered by the advertiser is to upload the content file directly or to set the viewer rating, popularity information and the like to specify the content target. The content directly uploaded by the advertiser is stored in the advertisement providing server 2 together with the advertiser information and the advertisement information.

If the advertiser registers the viewer rating or popularity as an advertisement criterion, the content searching means 211 automatically searches for the viewer rating or popularity in real time or periodically and stores corresponding content (S211). If you set up viewership or popularity information, for the objectivity of obtaining viewership or popularity data, you can register the URL of the site where the advertiser can refer to the data, or the ad serving server 2 will guide you to the reliable viewership or popularity information. We have already explained that you can choose from. For example, if the advertiser's advertising standard is the No. 1 viewer rating program of three terrestrial broadcasters announced by Company A, all content in various formats that have the same content on the Internet is subject to advertisement insertion. will be.

When the content meets the advertiser's advertisement criteria is secured, the first finger print extracting means 22 analyzes the content to extract, index and store the fingerprint (S22). In the present invention, the type of finger print may be any one or more of an image, audio and video finger print.

On the other hand, the homepage of the advertisement providing server 2 receives content for access users, and provides a search service and a distribution service of the content registered on the homepage. Here, when the content is registered on the homepage, the second finger print extracting means 23 extracts, indexes and stores the second finger print from the registered content (S23).

When data of the first finger print of the content according to the advertisement criteria and the second finger print of the content provided to the user are constructed, the content-based advertisement can be generated at any time. In the present invention, the advertisement file may be inserted in real time at the time of providing the content to the user, and the content in which the advertisement is inserted in advance may be prepared in advance and then provided to the user. Hereinafter, for convenience of description, it is assumed that a user requests to download content to insert an advertisement in real time.

When the user requests the download of specific content from the homepage, the advertisement file insertion means 24 searches and compares the second finger print of the requested content with the first finger print according to the advertisement criteria, and corresponds to the matching first finger print. Search for an advertisement to insert the advertisement into the content in real time. Because the fingerprint is to identify the content of the data, the advertiser's advertisement has the same content and can be inserted into content in different formats. It has already been described that the insertion position of the advertisement can be placed at any position of the content data and can be inserted only in the section where the contents match.

When the content with the advertisement is generated, the content transmission means 25 transmits the content to the user terminal (S25). The user is provided with an advertisement in the process of executing the downloaded content.

5 is a flowchart illustrating a method for providing an advertisement according to a second embodiment of the present invention. In the second embodiment of the present invention, in addition to the first embodiment, the advertisement providing server 2 partially compensates the author of the content in which the advertisement is inserted for the advertisement revenue earned from the advertiser. For convenience of description, components and operations of the first embodiment described above will be omitted.

The advertisement criterion registration means 21, the content search means 211, and the first finger print extracting means 22 perform the same steps as the advertisement providing method of the first embodiment.

When the content corresponding to the advertisement criteria is secured, the author information detecting means 221 analyzes the data of the content and automatically extracts the author information (S221). Here, the author information is information that is transparently encoded in the content data as identification information such as an author logo or author name or is part of the content data content.

Meanwhile, the advertisement providing server 2 has already registered copyright information by receiving content from the author, and extracts and indexes a fingerprint of the author's content. Therefore, when automatic detection of author information fails, the author fingerprint search means 222 compares the first finger print corresponding to the advertisement criterion with the fingerprint of the author content and previews the copyright information on the content of the matching advertisement criterion in advance. Save it. In FIG. 5, the author information detecting means 221 and the author fingerprint searching means 222 are used in parallel to secure the author information.

Thereafter, the second finger print extracting means 23, the advertisement file inserting means 24, and the content transmitting means 25 perform the same steps as the advertisement providing method of the first embodiment.

Upon completion of the content transmission, the author compensation means 26 inquires the author information corresponding to the advertisement inserted in the content and compensates at a predetermined ratio (S26).

As described above, an embodiment of the advertisement providing system and the advertisement providing method based on the contents of the multimedia content according to the present invention are configured. Although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical spirit of the present invention and the claims to be described below by those skilled in the art to which the present invention pertains.
