The advertisement monitoring apparatus 100 based on the content identifier according to an embodiment of the present invention may extract not only the content identifier concealed in the digital watermark but also the content identifier concealed in the packet by a digital watermark based information concealment technology. .

In the case of digital contents distributed online, most of them are distributed in the form of re-encoding by compression or the like, not in the form of a packet (eg, MPEG TS) converted for broadcasting digital contents. Therefore, in the case of digital content distributed online, the content identifier can no longer be extracted from the packet MPEG-TS, so that the content identifier can be extracted from the digital watermark embedded in the digital content.

On the other hand, in the case of a received broadcast content or a file stored in a TS format, extracting a digital watermark takes a long time, so a content identifier can be extracted from a packet (eg, MPEG TS) converted for digital broadcasting. .

When the sender inserts the content identifier and transmits it, the content identifier is inserted into both the content (using watermarking) and the packet, and the extracting unit 110 selects the content appropriately according to the situation of the receiving party that receives and monitors the content identifier. The identifier can be extracted.

The extractor 110 may grasp information about whether the digital content is an advertisement and how far is a movie or a drama by extracting the content identifier.

The searcher 120 searches for a content identifier associated with an advertisement to be monitored among the extracted content identifiers. Here, the content identifier associated with the advertisement searched by the searcher 120 may be a content identifier for the advertisement itself, or may be a content identifier for digital content associated with the advertisement.

The searcher 120 may search for the exposure time of the advertisement to be monitored and the content identifier associated with the connected content before and after the advertisement time among the extracted content identifiers.

The exposure time of the advertisement to be monitored may be used when generating a subsequent monitoring report. In addition, by referring to the content identifier associated with the content connected before and / or after the advertisement, the advertiser may be provided with information on the digital content to which the advertisement to be monitored is exposed.

The conversion requester 130 requests the content identifier conversion system to convert the content identifier for the digital content associated with the advertisement in order to obtain information about the digital content associated with the advertisement.

Here, the feature point of the advertisement to be monitored is stored in the feature point storage unit 180 to be described later, the feature point storage unit 180 receives the feature point of the advertisement to be monitored from the outside through the receiving unit 170, or received from the advertiser It may be storing from the beginning.

The detection unit 150 detects an advertisement to be monitored from digital content received through online or offline, for example, whether the advertisement for the 'a' product is exposed before and after the 'A' drama among the digital contents. Suppose you want to monitor whether or not.

In this case, the feature point storage unit 180 stores the feature points representing the characteristics of the advertisement for the 'a' product to be monitored.

The feature point extracting means 153 may extract a feature point representing the feature of the digital content from the digital content received online or offline.

In this case, the digital content may be an advertisement for a 'ga' product to be monitored, a content for a 'A' drama, and a digital content including other dramas or advertisements.

The comparison unit 156 compares the feature point of the advertisement for the 'a' product to be stored in the feature point storage unit 180 with the feature point of the digital content extracted by the feature point extraction unit 153.

As a result of the comparison in the comparison means 156, if a portion of the digital content that matches the feature point of the advertisement for the 'A' product to be monitored appears, the advertisement for the 'A' product to be monitored is displayed on the digital content. It can be judged as included.

When the advertisement to be monitored is detected by the detector 150, the calculator 160 may calculate the advertisement time of the advertisement to be monitored in units of minimum time.

Here, the providing unit 140 may provide a monitoring result for the advertisement to be monitored by using the advertisement time of the advertisement to be monitored and the information about the digital content associated with the advertisement.

The receiving unit 170 receives information about the digital content associated with the advertisement identified by the content identifier in response to the request for conversion of the content identifier for the digital content associated with the advertisement.

The feature point storage unit 180 stores a feature point representing a feature of the advertisement to be extracted extracted from the advertisement to be monitored. Feature points representing the characteristics of the advertisements to be monitored stored in the feature point storage unit 180 may be provided in advance from the advertiser, or may be received through the receiver 170.

Referring to FIG. 2, the content identifier may include a prefix code 210, an instance code 220, and a qualifier code 230.

Here, the Universal Content Identifier (UCI) is a standard for linkage between various identification systems, and a scheme for assigning and managing unique codes to individual resources for efficient distribution and utilization of identifiable resources or a linkage standard between different identification systems. to be.

That is, for example, if the target to use the identification scheme of the content identifier is broadcast content, each individual broadcast content is given a unique content identifier.

Prefix code 210 and instance code 220 are required parts of the content identifier.

Prefix code 210 refers to a Registration Authority (RA) that wants to monitor or assigns and manages UCI to digital content.

In addition, the instance code 220 may represent information about advertisements to be monitored or information related to digital content.

The qualifier code 230 may indicate a change in form, that is, a conversion form of content, not a change in meaning of digital content including an advertisement to be monitored.

That is, for example, in the case of digital content having the same content, the broadcast content provided offline through broadcast and the VOD content provided online are the same content provided by the same organization, and thus the same prefix code 210 and the same. Have object code 220.

However, since the conversion forms of the contents are different from the broadcasting contents and the VOD contents, they can be distinguished by the limited code 230.

As such, since the object code 220 and the restriction code 230 express information about the content, the object code 220 and the restriction code 230 may be referred to as content codes.

As described above, the content identifier is an identifier capable of identifying at least one metadata that facilitates identification of at least one of the information related to the caption advertisement or the digital content to be monitored.

As described above, the conversion requester 130 requests the content identifier conversion system to convert the content identifier for the digital content associated with the advertisement so that the content identifier-based advertisement monitoring apparatus obtains at least one metadata. In addition, the advertisement monitoring apparatus based on the content identifier may obtain various information about the digital content associated with the advertisement from the metadata.
