2 is a schematic diagram illustrating another embodiment of a system for providing a customized advertisement of an on-demand video service according to the present invention.

Another embodiment of a system for providing customized advertisement of video-on-demand service according to the present invention is a video file server 22, streaming server 32, connected to a network 12, such as the Internet connected to a high-speed communication network, as shown in FIG. To keyword-specific image search server 42, keyword-specific image feature database 52, keyword-specific ad search server 62, keyword-specific ad database 72, timetable database 82, and multiple viewer clients 92. It is composed.

As an embodiment of a customized advertisement providing system for an on-demand video service according to the present invention, first, the video file server 22 stores a video file for multimedia content, and transmits the stored video file to the streaming server 32.

This is for streaming a moving picture file stored in the video file server to the viewer client.

Next, the streaming server 32 transmits the video file transmitted from the video file server 22 to the viewer client 92 that distinguishes the video file from the video file.

In other words, in the system for providing customized advertisement of video-on-demand service according to the present invention, the streaming server 32 transmits the video file to the viewer client 92 so that the multimedia content is served through the viewer client 92. Is to send streaming on.

Next, the keyword search server 42 for each keyword extracts a key frame image of the video file stored in the video file server 22 and analyzes the extracted key frame image for each feature and keyword for each keyword. When image feature information for each keyword stored in an image feature database is associated, a keyword corresponding to the image feature information is stored in the timetable database 82 for each video ID according to the playing time of the video file.

For example, if the feature information analyzed by the keyword search server by key image of the video file stored in the video file server is similar to the image feature information corresponding to the "fan" in the keyword image feature database, the "fan" The keyword is stored in the timetable database according to the time of playing the video file.

In other words, the customized advertisement providing system of the video-on-demand service according to the present invention uses the feature information obtained by analyzing the key frame image of the video file corresponding to the multimedia content in order to provide the viewer with advertisement information related to the actual multimedia content. According to the playing time of the key frame image corresponding to the used feature information, advertisement information related to the corresponding keyword may be naturally exposed.

Meanwhile, the customized advertisement providing system of the video-on-demand service according to the present invention may use all keywords extracted by analyzing the key frame image of the video file, and information about the video file from the keywords extracted by analyzing the key frame image of the video file ( For example, keywords related to a title, a tag, a description of the corresponding content, etc. may be used.
