In addition, the client terminal 200 may be a mobile communication terminal, a computer or a PDA having a network connection function. In addition, it may be a so-called smart phone that is widely widely used in recent years.

The client terminal 200 further includes the following configuration in connection with the present invention in addition to such a conventional device. That is, the client terminal 200 acquires the video data and transmits it to the content sharing service providing system 100, receives the video or image data transmitted from the content sharing service providing system 100, and receives the video data from the received video or image data. It allows the user to select some sections and share video or image data for the selected sections through the content sharing system 300.

2 is a diagram showing the internal configuration of the client terminal 200 according to the present invention.

Referring to FIG. 2, the client terminal 200 includes an image acquirer 210, an audio acquirer 220, a query signal generator 230, and an interface manager 240.

The image acquirer 210 refers to a device such as a camera, for example, and the audio acquirer 220 refers to a device such as a microphone. The image acquisition unit 210 and the audio acquisition unit 220 obtain video and audio by user's manipulation to generate video data. In this case, the voice acquirer 220 may generate video data using only the image acquirer 210 without using the voice acquirer 220. The present invention is particularly useful when a user wants to share a screen broadcast while watching a broadcast such as a TV broadcast or a cable broadcast through a blog, a cafe, or a social network service (SNS). When played back, the video data may be acquired by bringing the image acquisition unit 210 or the image acquisition unit 210 and the audio acquisition unit 220 of the client terminal 200 onto the screen. For example, the image acquisition unit 210 may acquire moving image data by illuminating a camera on a screen and taking a moving image. Such a function may use a function built in the client terminal 200, but it is preferable that an application for implementing the function according to the present invention is installed in the client terminal 200 to operate the application.

The query signal generation unit 230 generates video data obtained by the image acquisition unit 210 or the image acquisition unit 210 and the audio acquisition unit 220 as a query signal, and generates the content sharing service providing system ( 100).

The interface manager 240 receives a video or image data from the content providing server 130 and performs a function of providing a selection interface for allowing a user to select some sections among the received video or image data. In addition, the interface manager 240 also performs a function of sharing the video or image data for the section selected by the user through the content sharing system 300.

When the interface management unit 240 receives the video data from the content providing server 130, the interface manager 240 provides image data for each frame constituting the video data through a selection interface. It is preferable to share the video data of the section including the data or the corresponding image data through the content sharing system 300.

Meanwhile, in the present invention, sharing video or image data through the content sharing system 300 may be performed by the following method.

As a first method, the client terminal 200 may directly transmit image or video data about a portion selected by the user to the content sharing system 300.

As a second method, the client terminal 200 requests image or video data of the image quality suitable for the content sharing system 300 to the content sharing service providing system 100 and transfers the received image or video data to the content sharing system 300. You can also use the method of transmission.

As a third method, a method in which the client terminal 200 directly transmits the image or video data of the image quality suitable for the content sharing system 300 through the content sharing service providing system 100 may be used.

These methods will be described in detail with reference to FIG. 3 and below.

Referring to FIG. 1 again, the content sharing service providing system 100 will be described.

First, the fingerprint extraction server 110 performs a function of extracting a fingerprint for video content. That is, the fingerprint extraction server 110 extracts and indexes the fingerprint for the video content collected or otherwise retained through the network.

Here, fingerprint refers to feature data representing characteristics of data such as audio data, image data, or moving picture data, and is also referred to as fingerprint data, DNA data, or genetic data. As a technique for extracting such fingerprints and comparing the data using the fingerprints, various methods have been proposed by the prior art. When such fingerprints are used, it is easy to discriminate whether data is identical or not. Therefore, Have recently been widely used. For example, in the case of audio data, a fingerprint is generated using various characteristic data (eg, frequency, amplitude, etc.) representing the characteristics of the audio data, and in the case of image or video data, various characteristic data (eg, The fingerprint may be generated using motion vector information, color information, etc. of the frame. The present invention is not intended to generate the fingerprint itself, and any form of fingerprint generating / extracting method according to the prior art can be used as it is, so a detailed description thereof will be omitted. Patent Application No. 10-2007-0044251 filed by the present applicant (method and apparatus for generating audio fingerprint data and method and apparatus for comparing audio data using the same), No. 10-2007-0054601 10-2007-0060978 (method and system for clustering video data having the same video data among each other), No. 10-2007-0071633 (video data retrieval service using video data clusters 10-2007-0091587 (Method and apparatus for setting and providing advertisement data using moving picture data cluster), and 10-2008-0051688 (Moving picture processing method and apparatus) A method of generating a fingerprint of image or video data and a method of comparing data using such a fingerprint are described, In the fingerprint generation and extraction method of the present applicant it may be used in the invention. In short, regardless of the method of extracting the fingerprint, the fingerprint generating / extracting technique known in the art can be used as it is.

The fingerprint extraction server 110 extracts the fingerprint for the video content and stores it. As described below, the content recognition server 120 provides the video information on the query signal requested from the client terminal 200. Used to determine

Meanwhile, the content recognition server 120 performs a function of determining video information corresponding to the query signal requested from the client terminal 200. As described above, the query signal may be video data obtained from the client terminal 200. The content recognition server 120 extracts a fingerprint from the received video data and extracts the finger through the fingerprint extraction server 110. Corresponding (matching) moving picture information is determined by comparing a fingerprint matching the print. In this case, the video information may include an identifier (ID) of the matched video and playback position information. The playback position information may be a frame identifier (ID) indicating which frame of the frames constituting the video, or time information indicating which time section is included in the entire video time section. As described above, a technique for generating a fingerprint and comparing fingerprints to find fingerprints matching each other may use the conventional technology as it is, and this is not a direct object of the present invention, and thus detailed description thereof will be omitted. .

The content providing server 130 transmits video or image data about the determined video information to the client terminal when the video information is determined by the content recognition server 120. Since the video information includes a video identifier and playback position information (frame identifier), the content providing server 130 performs video data on a section including a position corresponding to the playback position information among the video data corresponding to the determined video identifier. Will be sent to the client terminal. For example, if the video ID 3 and the frame identifier 35 are determined as the video information, the video data for the section including the 35 th frame of the video ID 3 is transmitted to the client terminal 200. In this case, it is preferable to transmit a frame in a predetermined range including the corresponding frame. For example, video data for a section including 20 frames before and after the 35th frame may be transmitted.

Meanwhile, the content providing server 130 may transmit image data to the client terminal 200 instead of video data. As described above, since the frame identifier is determined as the moving picture information, image data for each frame may be transmitted to the client terminal 200. In this case, the image data for the frame of the predetermined range including the corresponding (matching) frame can be transmitted to the client terminal 200.

Meanwhile, the content providing server 130 may transmit video or image data to the client terminal 200 and also transmit video identifier information and playback position information. This information is used in the second and third of the above-described content sharing methods.

Through this process, the client terminal 200 receives video or image data as a response to the query signal requested by the client terminal 200 from the content sharing service providing system 100. In this case, the interface manager 240 may be configured as described above. A process of providing a selection interface for selecting a desired portion by the user and sharing image data of the portion selected by the user through the content sharing system 300 is performed.

Meanwhile, in the present invention, the content sharing system 300 is a concept including all kinds of systems for sharing content, for example, a blog service server that provides a blog service, a community such as a cafe, a so-called cafe. It may be such as a service server for providing a service, an SNS service server for providing an SNS service. As well known as an SNS service server, it may be a commercial service such as facebook, twitter, cyworld, and the like. In recent years, since the trend of making the SNS service directly available in an application is increasing, the interface management unit 240 includes such a function in the present invention so that the user selects the corresponding SNS service and immediately logs in to the SNS service. You can also upload data to the SNS service immediately.

3 is a flowchart illustrating an embodiment of a method for providing a video content sharing service using a client terminal according to the present invention. 3 illustrates the first method of the content sharing process described above.

Referring to FIG. 3, first, as described above, when the client terminal 200 finds a broadcast screen to be shared while watching a TV broadcast, the client terminal 200 includes an image acquisition unit 210 of the client terminal 200 on the screen. The video data is acquired at step S100.

The query signal generator 230 of the client terminal 200 transmits the obtained video data to the content sharing service providing system 100 as a query signal (S110).

When the query signal is received, the content recognition server 120 of the content sharing service providing system 100 determines the video information corresponding to the received query signal (S120). As described above, the determination of the moving picture information is performed by determining the matching moving picture information by comparing the fingerprints stored in the fingerprint extraction server 110 with the extracted fingerprint from the moving picture data received as the query signal. . Also, the determined video information may be a video identifier and a frame identifier (playback position information).

When the video information is determined, the content providing server 130 of the content sharing service providing system 100 transmits the video or image data about the determined video information to the client terminal 200 (S130). At this time, as described above, it is preferable to transmit the video or image data for the section including the position corresponding to the playback position information among the video data or image data corresponding to the determined video identifier to the client terminal.

When the video or image data is received, the interface manager 240 of the client terminal 200 provides a user selection interface for allowing a user to select some sections from the received video or image data (S140). When the user selects some of the video or image data through the user selection interface (S150), the content may be shared by transmitting the video or image data for the selected portion to the content sharing system 300 (S160) ( S170).

4 is a flowchart illustrating another embodiment of a method for providing a video content sharing service using a client terminal according to the present invention. 4 is for the second method of the content sharing process described above.

In the embodiment of FIG. 4, steps S100 to S150 are the same as in FIG. 3, and thus description thereof will be omitted. When the user selects the video or image data in step S150, the client terminal 200 transmits selection related data related to the video or image data selected by the user to the content sharing service providing system 100 (S180). In this case, the selection related data may include a video identifier, playback position information, and image quality information. The video identifier and the playback position information are transmitted from the content sharing service providing system 100 in step S130, and the client terminal 200 has the same and then transmits the information in step S180. The image quality information refers to image quality information to be used when transmitting and uploading selected video or image data to the content sharing system 300. The image quality information may be, for example, resolution information such as 800 × 600 dpi, 1024 × 768 dpi, and the like, which may be set by a user through an interface. Alternatively, the user may preset and store a desired resolution and automatically transmit the resolution to the content sharing service providing system 100. The content sharing service providing system 100 may have a plurality of contents having various image quality even with the same content, but may need to upload contents having different image quality depending on the user or the conditions of the content sharing system 300. Because. In the content sharing service providing system 100, the video or image data transmitted in step S130 is relatively small, since the display unit is generally small when the client terminal 200 is, for example, a smartphone, but the data of the content sharing system ( This is because the 300 may want to transmit higher quality data.

When the content sharing service providing system 100 receives such selection related data, the content sharing service providing system 100 transmits video or image data corresponding to the received selection related data to the client terminal 200 (S190). As described above, when the video identifier, the playback position information, and the image quality information are received as the selection related data, the video or image data corresponding to the image quality information is searched among the video or image data corresponding to the corresponding playback position information of the video identifier. And transmits it to the client terminal 200.

The client terminal 200 receives the video or image data and transmits (uploads) the content to the content sharing system 300 to share the content (S200 and S170).

5 is a flowchart illustrating still another embodiment of a method for providing a video content sharing service using a client terminal according to the present invention. The embodiment of FIG. 5 relates to a third method of the content sharing process described above.

The embodiment of FIG. 5 is the same from step S100 to step S180 in comparison with the embodiment of FIG. 4, except that in step S180, the selection related data is transmitted to the content sharing service providing system 100 and the content is received. There is a difference in that the shared service providing system 100 directly transmits the searched video or image data to the content sharing system 300 based on the selection related data (S210).

In operation S180 of FIG. 5, the selection related data may further include access information of the content sharing system 300 in addition to the selection related data of FIG. 4. This is because the content sharing service providing system 100 needs to directly access the content sharing system 300 and transmit the corresponding video or image data. The access information may include URL information of the content sharing system 300, an ID of a user of the client terminal 200, a password, and the like. The content sharing service providing system 100 may directly access the content sharing system 300 and directly transmit corresponding video or image data using the content sharing service providing system 100.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is of course possible to make modifications.
