Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a configuration of a content providing system according to an embodiment of the present invention.

A content providing system 100 according to an embodiment of the present invention may include a plurality of content production terminals 110, a service server 120, a first terminal 130 and a second terminal 140.

The content production terminal 110 may include a portable terminal such as a smart phone, a mobile phone, a personal digital assistant (PDA), a portable multimedia player (PMP), a tablet computer, a digital camcorder, , And transmits a video image of a specific event to the service server 120.

Here, 'specific event' is an event that a plurality of contents producers experience together at a specific time and space. For example, 'concert' of a famous singer, 'travel' with friends can be included in the 'specific event' have.

Therefore, the image (hereinafter, referred to as 'content') captured by each content production terminal 110 with respect to the specific event may include information on the same shooting time zone and shooting location, and when the sound is recorded, The photographing angle and the photographing angle may be different from each other.

The photographing time point and the ending time point, the information about the photographing place, the sound inclusion and the photographing angle can be stored as metadata of the contents, and the keyword related to the contents inputted by the contents producer can be stored as the metadata.

In addition, the name of the content may be displayed in a predetermined format in each content production terminal 110, or may be displayed in a specific name entered by assigning meaning to the content creator.

For reference, the transmission of a video image of a specific event to the service server 120 means that the content is transmitted through a social network service (SNS) or a home page provided by the service server 120 And the uploaded content may be stored in a storage space such as a cloud that is interlocked with the service server 120. [

At this time, the position to be stored may be different according to the relation (intimacy degree) between each content creator.

For example, when the degree of intimacy between each content creator is strong (hereinafter referred to as a "strong connection") (family, friends, company colleagues, etc.), each content creator prepares content in a predetermined directory or folder Can be uploaded.

Here, the predetermined directory or folder may be created in the storage space by a request from one of a plurality of content producers, or may be provided by the service server 120 as a default, and the corresponding directory or folder may be associated with an event Keywords can be tagged.

Further, when the degree of intimacy between each content creator is weak (hereinafter referred to as a "weak connection"), each content creator is only interested in uploading his or her content to a blog or a specific bulletin board, The location of the uploaded content is not important, and the service server 120 may store the content uploaded by each content creator at a predetermined location in the storage space according to the storage process.

On the other hand, the service server 120 can synchronize the contents received from each content production terminal 110 according to a muilti point view content creation request for a specific event.

For reference, each content production terminal 110 can upload content through the service homepage provided by the SNS or the service server 120, and the uploaded content can be stored in a storage space such as the cloud.

The service server 120 can perform synchronization based on one or more attributes of the event shooting point and the ending point, information on the shooting location, and sound when synchronizing the contents received from each content producing terminal 110.

Here, the service server 120 may perform the synchronization using the metadata including the shooting time point and the ending time point of each content, information about the shooting location, and the like.

If the metadata does not exist or the information included in the meta data can not be trusted, the features of the sound of each content may be extracted to identify overlapping sections, and synchronization may be performed based thereon. Alternatively, Synchronization can be performed through similarity comparison.

At this time, the service server 120 may synchronize each content in the above-described manner, and perform synchronization to match the actual time line of the event.

For reference, the range of 'actual time flow of events' may be set to the earliest shooting point and the latest ending point of all synchronized contents for the event.

In addition, the service server 120 can search contents to be synchronized by reflecting the relationship (degree of intimacy) between each content creator.

At this time, in the case of a strong connection, the service server 120 may search contents included in the directory or folder based on a tagged tag in a specific directory or folder as an object of synchronization.

In addition, in the case of a connection with a weak degree of intimacy, the service server 120 may search contents to be synchronized based on the keywords tagged in each content.

The relationship (degree of intimacy) between each content creator will be described later with reference to FIG.

Thereafter, the service server 120 transmits a plurality of contents synchronized to match the actual time flow of the event to the first terminal 130 according to the request of the user, and plays the content displayed on the first terminal 130 (Hereinafter, referred to as a 'content control interface') to the second terminal 140.

For this purpose, the service server 120 may receive and store the identifiers of the first terminal 130 and the second terminal 140 in advance.

For reference, the content displayed on the first terminal 130 may be displayed on the screen of the first terminal 130 in a non-divisional or multi-division manner. For this purpose, the service server 120 transmits the content to the first terminal 130 Specific applications can be transferred.

The first terminal 130 may include a set-top box or a TV (e.g., a smart TV) connected to a set-top box. The first terminal 130 may receive a plurality of contents from the service server 120, You can display on the screen in the form of

To this end, the first terminal 130 may receive and install a specific application from the service server 120.

Here, 'displaying the content on the screen in a non-divided form' means displaying only a specific content selected by the user from among a plurality of contents, and displaying the contents on the screen in a multi- And the like.

The specific content and the plurality of contents selected by the user can be selected through the content control interface of the second terminal 140. [

The second terminal 140 may include a portable terminal such as a smart phone, a mobile phone, a personal digital assistant (PDA), a portable multimedia player (PMP), or a tablet computer. From the service server 120 and display the content control interface on the screen of the second terminal 140.

The second terminal 140 may transmit control commands to the first terminal 130 or the service 130 through the content control interface displayed on the screen, To the server 120.

In this case, when the second terminal 140 directly transmits the control command to the first terminal 130, a wireless communication method such as Bluetooth may be used. For this purpose, the second terminal 140 and the first terminal 130 May be preceded by pairing.

Also, when the second terminal 140 transmits the control command to the service server 120, the service server 120 may transmit the control command to the first terminal 130.

The second terminal 140 may be any one of the content production terminals 110. However, for convenience of explanation, the content production terminal 110 and the second terminal 140 will be described separately.

2 is a diagram illustrating a content production process for a specific event according to an embodiment of the present invention.

FIG. 2 (a) is a view of the contents recorded by the fans participating in concerts of famous entertainers at the concert site, and contents produced by the fans attending the concert include the same space (concert place) and the same sound at the same time They have a common point.

In addition, the shooting time point and the ending time point may be different for each content, and the shooting angle may be changed depending on the position where the shooting is performed.

For reference, in the case of FIG. 2 (a), the relationship (degree of intimacy) between the contents producers may be a 'weak connection relation' in which similar interests and experiences are shared, but no direct social relations appear.

In this case, the content uploaded by each content creator may be stored in a predetermined position in the storage space according to the storage process of the service server 120, and the service server 120 may store the content Content can be retrieved.

For example, in FIG. 2 (a), a name of a famous entertainer, a date and place of a concert is added to keywords (A, B, and C (none of which have any social relation) participating in a concert of a famous entertainer (Blog, portal bulletin board, etc.) provided by the service server 120, the service server 120 searches for the keywords A, B, and B based on the keywords "name of famous celebrities, date and place of concert" And each content uploaded by C can be searched as a target of synchronization.

On the other hand, FIG. 2 (b) shows that the contents produced by the friends participating in the trip are the same space (travel place) and the same sound in the same time zone have.

In addition, the shooting time point and the ending time point may be different for each content, and the shooting angle may be changed depending on the position where the shooting is performed.

For reference, in the case of FIG. 2 (b), the relationship (degree of intimacy) between the contents producers can be a strong connection relationship in which a direct social relation is high while sharing similar interests and experiences.

In this case, when any one of the friends who has traveled requests a directory or folder creation to the service server 120 and a specific directory or folder is created in the storage space, the friends participating in the trip are informed of the trip You can upload content.

When a directory or a folder is requested to be generated by the service server 120, a keyword related to an event may be tagged, and the service server 120 may search for a content to be synchronized based on a keyword tagged in a directory or a folder .

3 is a block diagram illustrating a configuration of a service server according to an embodiment of the present invention.

The service server 120 according to an embodiment of the present invention may include a content synchronization unit 121, a content providing unit 122 and an interface providing unit 123, A data checking unit 121a, an audio feature extracting unit 121b, an overlapping interval determining unit 121c, and a synchronization unit 121d.

First, the contents synchronizing unit 121 can synchronize the contents uploaded by the respective contents producing terminals 110 via the SNS or the service homepage.

Specifically, the metadata checking unit 121a can check whether the metadata of each uploaded content is present, and extract information about the shooting time, the ending time, and the shooting location included in the metadata.

Here, the metadata may be information in the form of EXIF (EXchangeable Image File Format) including photographing time, ending time, and photographing place, and the information about the photographing place may include GPS information and tagging information And may include one or more.

If the metadata extraction unit 121b confirms that the metadata of each content does not exist, or that at least one of the shooting time point, the ending time point, and the shooting location information is unreliable from the metadata checking unit 121a, It is possible to extract the audio feature from the audio data.

For example, the audio feature extraction unit 121b may extract Fast Fourier Transform (FFT), Mel-Frequency Cepstral Coefficients (MFCCs), Linear Predictive Coding (LPC), Zero Crossing Rate (ZCR) Line Spectrum Frequency or the like can be used (it can be modified or combined with more than one), and then the extracted features can be further abstracted by using the above-mentioned algorithm through Delta calculation.

When using the extracted feature vectors, high-accuracy matching is possible, and the audio feature extraction unit 121b can reduce the size of the data by simplifying the data of these features.

For example, the audio feature extracting unit 121b may perform a Simplified-Delta process of simplifying the 2.5ms-length frame by a sum of 0.125 sec units of 50 units. At this time, In order to take advantage of the tendency, we can apply the Delta operation, which is the difference operation.

The overlapping section determination unit 121c can determine the interval in which sounds overlap with each other through comparing the similarities of the audio features extracted from the audio feature extraction unit 121b.

That is, if the content is photographed in the same time zone and at the same place, even if the shooting time point and the ending time point of each content are different from each other, there is necessarily a section in which the sounds coincide with each other, A section in which sounds are overlapped with each other can be determined through comparison of the similarities of the audio features extracted from the audio part 121b.

The synchronization unit 121d synchronizes the contents based on the shooting time point, the end time point, and the shooting location information extracted from the metadata checking unit 121a, or when the sounds determined by the overlapping interval determination unit 121c are overlapped with each other Content can be synchronized based on intervals.

At this time, the synchronization unit 121d may synchronize the content to match the actual time line of the event.

For reference, the contents synchronizing unit 121 can search contents to be synchronized by reflecting the degree of intimacy between the contents producers.

The degree of intimacy between users can be classified into either a strong connection relationship or a weak connection relationship. In the case of a weak connection relationship, the content synchronization section 121 searches contents to be synchronized based on the keywords tagged in the contents, The content to be synchronized can be searched based on the keywords tagged in the directory or the folder of the storage space.

Meanwhile, the content providing unit 122 may transmit to the first terminal 130 each content synchronized to match the actual time flow of the event from the synchronization unit 121d.

For reference, the content providing unit 122 may transmit all the synchronized contents to the first terminal 130 or may transmit selected contents from the second terminal 140 among the synchronized contents to the first terminal 130 .

The interface providing unit 123 may transmit a content control interface to the second terminal 140 to control the playback of the content displayed on the first terminal 130.

Here, the content control interface may include a screen display method (non-division, multi-division, etc.) of contents, selection of contents for reproducing one or more contents, volume control function and the like.

A detailed description of the content control interface will be given later with reference to Fig.

4A and 4B are flowcharts illustrating a content providing process according to an embodiment of the present invention.

Hereinafter, the flow charts of FIGS. 4A and 4B will be described with the service server 120 as a main body.

The service server 120 receives contents from a plurality of content production terminals 110 (S401).

Here, the reception of the content may include uploading via the SNS or the service homepage provided by the service server 120, and the received content may be stored in a storage space such as a cloud.

The service server 120 can retrieve contents to be synchronized by reflecting the degree of intimacy between contents producers among the contents received at S401, and the description thereof has been described above, so that a detailed description will be omitted.

After S401, the service server 120 confirms whether the metadata of each content is present (S402).

At this time, it is possible to confirm whether or not the metadata exists and also whether the shooting time and the end time of the content included in the meta data and the reliability of the information about the shooting location are reliable.

If it is determined that the metadata exists, and the meta data includes the shooting start time, the ending time, and the shooting location of the corresponding content, the service server 120 synchronizes the respective contents based on the metadata (S403) .

As a result of the determination in S402, if the meta data does not exist, or the information about the shooting time point and the ending time point of the content included in the meta data can not be trusted, the service server 120 extracts (S404).

At this time, the algorithm for extracting the audio characteristic is omitted in the above description.

After step S404, the service server 120 determines a section in which sounds are overlapped with each other through comparing the similarities of the extracted audio features (S405).

After step S405, the service server 120 synchronizes the contents based on the overlapped periods of the sounds determined in step S405 (step S406).

After S403 or S406, the service server 120 completes the synchronization by matching each synchronized content to the actual time flow of the event (S407).

After receiving the content request from the first terminal 130 or the second terminal 140, the service server 120 transmits the content matched to the actual time flow of the event to the first terminal 130 (S408) ).

5 is a diagram illustrating a user interface according to an embodiment of the present invention.

The first terminal (smart TV) 130, which is the main screen, can display a plurality of contents received from the service server 120 on the screen, and the second terminal (tablet computer) 140, which is the second screen, Can be displayed on the screen.

The content control interface may include content of each content creator (such as photo and personal information) 510 and content of each content creator 520 matched to the actual time-flow of the event, as shown in FIG. 5, A playback button 530 and a status bar 540 indicating a playback position and adjusting a playback position and a volume control bar 550. [

Here, the status bar 540 may correspond to the actual time flow of the event, and the content 520 of each content producer may be displayed differently in length depending on the ratio of the playback time to the actual time flow of the event, Each content creator can be displayed in a different color.

Accordingly, the user of the second terminal 140 can intuitively grasp the content of each content producer and the playback time of the content through the content control interface.

In addition, since it is possible to intuitively grasp the overlapping sections of all the contents with respect to the event, if it is desired to view various shooting angles in a specific time interval, the contents can be easily and conveniently selected Can

The user can select any one of the contents of a specific content producer from the content control interface of the second terminal 140 and listen to it through the first terminal 130. If the user wishes to view various shooting angles of a specific time period The content may be selected and viewed simultaneously through the first terminal 130.

At this time, the screen division method of the first terminal 130 may be such that a plurality of selected contents are displayed in a uniform screen area, or asymmetrically, a specific content is displayed in an area of a larger screen, Area to be displayed.

In addition, the arrangement of the contents can basically be such that the area of the screen is arranged without overlapping with the form in which the first terminal 130 can overlap, such as the PIP supported by the first terminal 130.

In FIG. 5, a specific content is displayed asymmetrically in an area of a larger screen, and the remaining contents are displayed in an area of a smaller screen.

5, the case where three content producers participate in a specific event has been described for convenience of explanation. However, as the number of content creators and the number of contents of each content creator increase, It is possible to provide more intuitive and convenient convenience to the user who controls the server.

6 is a diagram illustrating a synchronization method according to an embodiment of the present invention.

FIG. 6 shows a method of synchronizing based on audio features extracted from the content of each content producer. As described above, even if there is no metadata in the content of each content creator or metadata exists, May be performed if the information about the user is not reliable.

As shown in (b) of FIG. 6, audio features of each content can be extracted to extract a section in which sounds overlap each other, and sections in which sounds overlap each other are displayed in respective colors.

A detailed description of a method of extracting a section in which sound is overlapped will be described later with reference to FIG.

Thereafter, as shown in (c) of FIG. 6, each content can be synchronized based on a period in which sound is overlapped, and the synchronization can be completed by matching the time flow of the event.

Such synchronized contents can be reproduced similar to the time-course of the event.

FIG. 7 is a diagram illustrating a synchronization method through comparison of similarity according to an embodiment of the present invention.

The synchronization method of FIG. 7 is a specific example of a method of extracting a section in which sound is overlapped as shown in FIG. 6 (b), and is a matching process between single images through similarity comparison.

First, the service server 120 divides the query moving image and the comparison moving image into frames of a constant hop size, and compares feature vectors extracted therefrom in a window sliding manner.

It is possible to sequentially synchronize the frames of all comparison images from the first frame to the last frame of the query moving image and to synchronize them with frames having a minimum distance value, that is, a frame having high similarity.

For reference, algorithms for calculating the distance difference between multi-dimensional data such as Euclidean distance can be applied to the measurement of the distance.

8 is a flowchart illustrating a content providing process of a second terminal according to an embodiment of the present invention.

First, the second terminal 140 receives the content control interface from the service server 120 and displays it (S801).

If at least one content is selected through the content control interface after step S801, the second terminal 140 generates the point content (i.e., the first content) to the first terminal 130 or the service server 120 including the identifier of the selected content and the reproduction time information (S802).

That is, the user can select and view various shooting angles (contents photographed at the viewpoint of each content creator) present in a specific time period of a specific event.

After the step S802, the second terminal 140 transmits a control command to the first terminal 130 through the content control interface, such as a screen display method (non-division, multi-division, etc.) To the first terminal (130) or the service server (120).
