  FIG. 1 is a schematic diagram showing an embodiment of an audio-video distribution system according to the present invention. The mobile communication network 1 is a communication network that is operated by a content distribution company, for example, connected via the Internet. The audio / video distribution system according to the present invention includes at least a matching server 2, a distribution server 3, and a user terminal 4 in a mobile communication network.

  The matching server 2 is a means for receiving meta information of each content and advertisement information and a distribution request transmitted from the user terminal 4, a means for storing meta information of each content and advertisement information, and responding to the distribution request from the user terminal 4. And means for matching the content and the advertisement information based on the respective meta information, and means for transmitting the matching information to the distribution server 3. Here, content means a piece of information widely recorded and transmitted on an information medium, and includes, for example, video, music, text, or a combination thereof. The advertising information means information such as products, services, and businesses that are transmitted to the general public for commercial purposes. The meta information is information described with respect to certain specific information (for example, certain specific content), and refers to information that has been standardized to some extent and has an expression format. For example, it includes information specifying the location of the content, summary of the content, other content with close relevance, or information that matches the user's preference. Finally, the matching information means information that associates content requested by the user terminal 4 with specific advertisement information.

  The distribution server 3 includes means for receiving content, advertisement information and matching information, means for storing the content and advertisement information, and means for associating the content and advertisement information with each other based on the matching information and distributing them to the user. The distribution server receives the produced content and the advertisement information from the content creator and the advertisement information creator 8, respectively, and stores them in the storage means provided in the distribution server. In response to receiving the matching information transmitted from the matching server 2, the distribution server 3 matches the stored content and advertisement information based on the matching information, and requests the content from the user terminal For example, via the Internet.

  The user terminal 4 is assumed to be, for example, a mobile phone terminal or a laptop computer. However, the user terminal 4 is not limited thereto, and may be any terminal having a terminal ID that can identify the user.

  The audio / video content distribution system according to the present invention further includes a content viewing information database 5. The matching server 2 includes means for receiving and storing content viewing history information from the content viewing information database 5. The matching means included in can be configured to perform matching based on the content viewing history information. Here, the content viewing information database 5 has a function of storing viewing information of content distributed via the distribution server. The viewing information stored in the content viewing information database includes, for example, the user's age, sex, past content distribution history, viewing time of the distributed content, and the like. Such content viewing information can be configured to be transmitted to the viewing information database from the user terminal that has received the content distribution.

  The user's viewing history information stored in the viewing information database is analyzed from various angles. For example, it is possible to obtain an analysis result indicating what kind of content is being viewed and what age group is viewing a specific content in what time zone. Based on these analysis results, we will create new broadcast content such as content that introduces content viewing status rankings and content that conveys the general trend of the world derived inductively from accumulated viewing information. (6) It is conceivable to distribute it to the user. In this case, the content to be broadcast is recorded and viewed by DVR or 1-segment mobile phone (7).

  Hereinafter, an embodiment of the present invention will be described with reference to the flowchart shown in FIG. First, the produced content and advertisement information are provided as electromagnetic information from the producer to the distribution server 3, and the provided content and advertisement information are respectively stored in the distribution server 3 (STEP 1). Next, each of the content creator and the advertisement information creator provides the meta information used for matching the content and the advertisement information to the matching server 2 and stores them in the matching server 2 (STEP 2). ). Note that STEP2 may be performed simultaneously with STEP1.

  More specifically, it can be explained as follows. First, a video taken by the poster is posted using a mobile terminal such as a mobile phone. The posted content is added with metadata such as poster information (copyright information) and tag information. The posted content is stored in the content distribution server 3, and the metadata of the content is stored in the matching server 2. On the other hand, metadata such as creator information (copyright information), advertisement client information, and tag information is added to the advertisement information produced by the advertisement creator. The advertisement information is stored in the content distribution server 3, and the meta information of the advertisement is stored in the matching server 2.

  As mentioned above, content creators can post content using mobile terminals, but they can shoot, edit, and produce media suitable for television program broadcasting (HD-DV, HD-CAM, etc.). It is also possible to provide updated content. In this case, the content is converted into a format suitable for viewing on the information terminal. Metadata such as poster information (copyright information) and tag information is added to the content. The posted content is stored in the content distribution server 3, and the metadata of the content is stored in the matching server 2.

  Next, the user uses the user terminal 4 to transmit a signal requesting distribution of content that the user desires to view to the matching server 2 via the Internet (PULL type) (STEP 3). The matching server 2 that has received the distribution request from the user terminal 4 executes matching between the content requested by the user and the advertisement information to be distributed in addition to the content (STEP 4). Matching between the content and the advertisement information is executed based on at least the content requested by the user. More specifically, matching is executed based on the respective meta information provided by the content creator and the advertisement information creator and stored in the matching server.

  The matching of content and advertisement will be specifically described. First, content and advertisement information are clustered based on the respective meta information. Each cluster is connected under a certain weight. This weighting changes dynamically by heuristically learning whether an advertisement has been received. The matching algorithm described here is merely an example for clarifying the contents of the present invention, and does not limit the present invention.

  As will be described later, it is also possible to determine advertisement information to be added to content based on user information. That is, the users are clustered based on the individual information, and the advertisement information is clustered based on the meta information. Each cluster is linked with a certain weight. This weighting changes dynamically by heuristically learning whether an advertisement has been received. The matching algorithm described here is merely an example for clarifying the contents of the present invention, and does not limit the present invention.

  By combining these two types of matching, it is possible to improve the matching accuracy of the user, content, and advertisement information. However, since there is no individual information of the user at the initial stage, it should be added to the content by matching the content with the advertisement. The advertisement information is determined. If individual user information is accumulated thereafter, matching based on the user information becomes more important.

  Note that content distribution is not only performed when there is a distribution request from the user, but may also be distributed by a method specified by the distribution company (PUSH type). In this case, the matching process described above is also executed. .

  The matching information obtained as a result of the matching is transmitted from the matching server 2 to the distribution server 3 by a known method (STEP 5). In response to receiving the matching information, the distribution server 3 adds the advertisement information specified by the matching information to the content requested by the user and distributes it to the user terminal 4 (STEP 6).

  The user who has received the distribution of the content and the advertisement information from the distribution server 3 views the content and the advertisement information using the user terminal 4 having a terminal ID that can identify the user (STEP 7). At this time, the user can view the advertisement information or can select not to view the advertisement information. When the user chooses to view the advertisement information, a certain point is given to the user, and at the same time, a part of the advertisement revenue is provided to the content creator. Thereby, an incentive to view the advertisement information can be given to the user. The user may select whether to view the advertisement before or after viewing the content. If the content that the user wants to view is clear, it may be done before viewing, but if the user's viewing request is not clear, an advertisement attached to it depending on whether the user likes the content or not. Since it can be said that whether or not information viewing is desired depends to some extent, it is preferable to select after viewing. These are matters that can be appropriately determined by the distribution company.

  As described above, the user can select whether or not to view the advertisement information distributed together with the content desired by the user, but whether to view the additionally distributed advertisement actually made by the user. Information such as the content of the advertisement information, the viewing time or the viewing date / time when the user chooses to view is sent from the user terminal 4 to the viewing information database 5 as viewing history information. (STEP 8) and stored (STEP 9). The viewing history information of the user stored in this way can be configured to be transmitted from the viewing information database 5 to the matching server 2. The transmitted viewing history information is used to make the matching between the content executed by the matching server 2 and the advertisement information more accurate.

  Next, the viewing history information of the user stored in the viewing information database is analyzed (STEP 10). By this analysis, for example, various information such as content access ranking, genre access ranking, transition of the number of accesses for each content (weekly, daily unit, etc.), gender and age of a user who has viewed a specific content, etc. Can get.

  Based on the analysis result thus obtained, a new content can be produced (STEP 11). As a specific example, it is conceivable to newly create broadcast content and distribute it to the user. In this case, the broadcast content can be recorded and viewed by DVR or 1-segment mobile phone. . As broadcast content, a program introducing content ranking, a trend information program that conveys the trend of the world from the ranking data, or a variety program with popular content as the theme can be assumed. In addition, when content that has been shot, edited and produced with media suitable for TV program broadcasting (HD-DV, HD-CAM, etc.) is provided, it is produced with appropriate media from the beginning, so there is a problem with quality. This is advantageous in that no occurrence occurs.

  It is possible to add no advertising information to the broadcast content produced in this way. Further, when the recorded video is played back on the information terminal, privilege information can be obtained based on the user information obtained from the terminal ID.

  All examples and conditional terms listed herein are provided in order to provide the reader with a better understanding of the principles of the invention, and the invention is specifically recited herein. The examples and conditions are not limited. Further, it is to be understood that all expressions presented herein broadly encompass their functional equivalents.

It is the schematic which shows one embodiment of the audio video delivery system according to this invention. 3 is a flowchart according to an embodiment of the present invention.
