Although not shown in FIG. 1, the system may further include a separate configuration required for the implementation of the method according to embodiments of the present invention.

The service server 100, which is a component of the system, may be referred to as a content synchronization history identifying apparatus 100 in that it performs a content synchronization history identification method according to an embodiment of the present invention.

2 is a block diagram of an apparatus for identifying a synchronization history of content according to another embodiment of the present invention. Hereinafter, the configuration and operation of the content synchronization history identifying apparatus 100 will be described in detail with reference to FIG. For convenience of explanation, the apparatus 100 may be abbreviated as a device 100 for identifying a synchronization history of contents.

2, the apparatus 100 may be configured to include a processor 101, a network interface 102, a memory 103, and a storage 104. As shown in FIG.

The processor 101 controls the overall operation of each configuration of the device 100. The processor 101 may be configured to include a Central Processing Unit (CPU), a Micro Processor Unit (MPU), a Micro Controller Unit (MCU), or any type of processor well known in the art. The processor 101 may also perform operations on at least one application or program to perform the method according to embodiments of the present invention. Apparatus 100 may include one or more processors.

The network interface 102 supports wired and wireless Internet communication of the device 100. In addition, the network interface 102 may support various communication methods other than Internet communication. To this end, the network interface 102 may be configured to include various communication modules.

The network interface 102 can transmit and receive contents to / from the user terminal 200 via the Internet. The network interface 102 may also send and receive various interfaces used to perform the method according to an embodiment of the present invention with the user terminal 200. The interface may include at least one of information about synchronized content and change history information generated by the device 100. [

The memory 103 stores various data, commands and / or information. The memory 103 may load one or more programs 105 from the storage 104 to perform the content synchronization history identification method according to embodiments of the present invention. RAM is shown as an example of the memory 103 in Fig.

The storage 104 may non-provisionally store the one or more programs 105, the synchronization content 106, and the metadata 107. In FIG. 2, synchronization software is illustrated as an example of the one or more programs 105.

In the above description, the case where the apparatus 100 is the service server 100 is described as an example, but the apparatus 100 may be the user terminal 200 or the like. That is, the user terminal 200 may be configured to include each component of the apparatus 100 described above. Accordingly, the user terminal 200 may execute the synchronization software through the processor to generate the change history information due to the synchronization of the contents, without receiving the information from the service server 100 itself.

Hereinafter, embodiments of the present invention will be described in detail based on the description of FIGS. 1 and 2. Hereinafter, it is assumed that the methods according to embodiments of the present invention are performed by the apparatus 100.

3 is a flowchart of a synchronization history identification method for content according to another embodiment of the present invention.

Referring to FIG. 3, the apparatus 100 may receive terminal content from the user terminal 200 (S10). The terminal content is a content temporarily or non-provisionally stored in the user terminal 200. When the device 100 receives the terminal content, the terminal content becomes the reference content for synchronizing the content to be synchronized. That is, the device 100 may change the content to be synchronized to the terminal content. Here, the terminal contents and the synchronization target contents may be different versions of contents based on the same contents, respectively.

The device 100 may store the content to be synchronized in advance. At this time, when the terminal content is received from the user terminal 200, the device 100 can identify the content to be synchronized based on the file name, content attribute, and the like of the received terminal content.

The device 100 can determine whether there is a change in the received terminal content based on the content to be synchronized (S20). That is, the device 100 may compare the synchronization target content with the received file of the terminal content to determine whether a change exists.

As a result of the determination, if there is a change, the device 100 can synchronize the synchronization target content and extract the change (S30). In other words, If there is a difference in the image, it can be identified and extracted. The extraction process may be performed in synchronization with the content to be synchronized in the apparatus 100. Based on the extracted changes, the device 100 may synchronize the content to be synchronized with the terminal content.

The apparatus 100 may image-convert the area where the change is extracted on the terminal content. In addition, the apparatus 100 may image-convert the scheduled change area on the synchronization target content (S40). For example, it is assumed that the terminal content and the content to be synchronized are five pages in total. It is also assumed that a part of the page 4 on the terminal content is changed with respect to the content to be synchronized.

At this time, the apparatus 100 may determine that there is a change in the data corresponding to a part of the page 4, and extract the change. Also, the apparatus 100 can image-convert page 4, which is an area where the change is extracted. To this end, the device 100 may perform capturing for page 4.

Also, the apparatus 100 may image-convert page 4, which is a scheduled change area, on the content to be synchronized. Here, the scheduled change area is an area on the synchronization target content corresponding to a partial area where the change is located on the terminal content. That is, the change scheduled area is an area where the change is scheduled to be applied through synchronization on the synchronization target content. In other words, the area to be changed is an area which has not yet been synchronized, but is an area to be replaced with the change after synchronization is performed.

The apparatus 100 may generate the change history information based on the image conversion result (S50). The change history information may be information transmitted from the apparatus 100 to the user terminal 200 and displayed on the user terminal 200. [

The device 100 may also generate meta information for the generated change history information in step S50. At this time, the generated meta information may include location information on the change. That is, the device 100 may identify the location of a part of the page, which is a location where a change is present on page 4 in the above example, and may generate the metadata based on the location. Since the change history information has unique meta information, the device 100 may provide a search function for the change history information. That is, when a change history inquiry for specific content is requested from the user terminal 200, the device 100 inquires the change history information based on the meta information of the change history information requested to be inquired and provides the change history information to the user terminal 200 You may.

The synchronization result and the change history information may be provided as a synchronization service to the user terminal 200 through the interface according to the embodiments of the present invention when the user terminal 200 accesses the device 100. [ 4, an interface for providing a synchronization result among the interfaces provided to the user terminal 200 will be described.

FIG. 4 is an illustration of a content synchronization service identification service according to another embodiment of the present invention.

In step S50, the device 100 can detect the connection of the user terminal 100. [ In addition, the device 100 may receive a request for a synchronization result according to the progress of synchronization in step S30 from the user terminal 200. [ At this time, the request may in particular be a display request for a synchronization result.

As the device 100 receives the request, it may provide an interface for displaying the result of the synchronization to the user terminal 200.

At this time, the interface may include content information synchronized as a result of synchronization for a preset period of time before receiving the request among a plurality of contents.

Referring to FIG. 4, the apparatus 100 may provide an interface 401 to a user terminal 200 as it senses the connection of the user terminal 200. The interface 401 may include synchronization history information for one or more contents that have been performed for a preset period of time. In addition, the synchronization history information may include information on synchronization success or failure, synchronization time, and the like. The interface 401 may include a setting menu for changing the predetermined period.

The device 100 may provide the interface 402 to the user terminal 200 upon receiving a request for a synchronization result from the user terminal 200. The interface 402 may include details of each content synchronized with each synchronization point in time. Or the device 100 may provide only the last synchronization details at the time the request was received from the user terminal 200 via the interface 402. [ The interface 402 may include final version information 412 of each content. In addition, the interface 402 may include information 413, 414, and 415 on synchronization results for a predetermined period.

Referring to FIG. 4, the information 413 may be information on the synchronization result of the first time point during a predetermined period. The information 414 may be information on the synchronization result of the second time point during a predetermined period. The information 415 may be information on the synchronization result of the third time point during a predetermined period.

For example, when the device 100 receives a request for a synchronization result from the user terminal 200 at a first time point, the device 100 transmits, via the interface 402, the final version information 412 and the information (413).

In addition, when the device 100 receives a request for a synchronization result from the user terminal 200 at a second time point, the final version information 412 and information 414 of the content at the second time point, via the interface 402 ). ≪ / RTI > At this time, the apparatus 100 may provide information 413 and information 414 together.

In addition, when the device 100 receives a request for synchronization result from the user terminal 200 at the third time point, the final version information 412 and the information 415 of the content at the third time point, via the interface 402 ). ≪ / RTI > At this time, the device 100 may provide information 413, information 414 along with information 415.

The information 413, 414, and 415 may be thumbnail information for synchronized content.

Figure 5 is an example of the synchronized content referenced in some embodiments of the invention.

As a result of the image conversion in step S40, the apparatus 100 may generate an image of the area from which the change is extracted as described above. In addition, the device 100 may perform an identification process for the change on the generated image. In this example, the device 100 may generate an image of page 4 where the changes are present, and may perform an identification process for a portion of the area where the change on the generated image is located.

In addition, the apparatus 100 may generate link information on the change history information generated in step S50 on the synchronized content according to the progress of the synchronization in step S40. Accordingly, upon receiving the input requesting the link information from the user terminal 200, the device 100 may transmit the change history information to the user terminal 200. [

Document 500 is shown as an example of synchronized content in FIG. The document 500, which is the synchronized content, may include link information 511 generated by the device 100. At this time, the document 500 may include the user information 512 that transmitted the terminal data that is the basis of the final synchronization. This is for the convenience of the next user of the synchronized document 500 when a plurality of users edit the document 500 while sharing it.

When the apparatus 100 receives the input requesting the link information 511, the apparatus 100 may transmit the information 520 about the extracted region 530 to the user terminal 200. Area 530 may include changes 540. Depending on the use of the link information, the user can quickly access the changes 540 of the synchronized document 500. On the other hand, referring to FIG. 5, the change 540 has been identified by the device 100.

FIG. 6 is an illustration of content displayed with changes in synchronization referenced in some embodiments of the invention. The change information shown in FIG. 6 is an example of the change history information. Document 600, 650 is shown as an example of synchronized content in FIG.

According to an embodiment of the present invention, in step S50, the apparatus 100 may receive terminal content including changes other than the change on the area where the change is extracted for a predetermined period of time. The apparatus 100 may extract the other changes from the received terminal contents and convert the extracted regions into image regions.

The device 100 may generate change history information based on the image transformation. At this time, the change history information may include the change information and the generation order information of the other change.

Referring to FIG. 6, region 610 of document 600 may include changes 620. It is assumed that the device 100 has received terminal content including the changes 620 and other changes 630 and 640 in the area 610 of the document 600. [ This may be the case where the user terminal 200 transmits the changed terminal content for a predetermined period or transmits the terminal contents including the other changes 630 and 640 for a predetermined period by another user terminal.

The device 100 may also perform image conversion at step S40 on the terminal content including the other changes 630 and 640. [ Based on this, the device 100 can update the change history information generated in step S50. For example, the device 100 may generate the order information 621, 631, 641 to which the change is applied in the area 610 of the document 600. [ In this case, the apparatus 100 may generate change information to which the order information is mapped.

Meanwhile, according to another embodiment of the present invention, in step S50, the apparatus 100 receives terminal contents including additional changes to the change on the extracted area for a predetermined period of time It is possible. The apparatus 100 may extract additional changes from the received terminal content and image-convert the extracted regions.

The device 100 may generate change history information based on the image transformation. At this time, the change history information may include information that the change and the additional change are sequentially displayed.

Referring to FIG. 6, region 645 of document 650 may include a change 651. It is assumed that the device 100 has received terminal content including additional changes 652 and 653 for the change 651 on the area 645 of the document 650. [ This is because, when the user terminal 200 transmits the terminal content to which the change is added to the same area again for a predetermined period or transmits the terminal content including the additional changes 652 and 653 for a predetermined period in another user terminal It can be one case.

The device 100 may also perform image conversion at step S40 for the terminal content that includes the additional changes 652, Based on this, the device 100 can update the change history information generated in step S50. For example, the device 100 may generate display information 651, 652, 653 in which the changes are stacked and displayed in the order in which the changes are added to the area 645 of the document 650. In this case, the apparatus 100 may generate change information including display information in which the change is stacked.

When any one of the stacked and displayed changes is selected through the user terminal 200, the device 100 can receive the change and transmit information on the selected change to the user terminal 200. In this case, of the stacked and displayed changes, information on the selected change may be displayed on the user terminal 200. [

7 is an exemplary diagram of change history information generated for comparison of synchronization content and terminal content referenced in some embodiments of the present invention.

According to an embodiment of the present invention, at step S50, the apparatus 100 may merge the image conversion result for the area from which the change was extracted and the image conversion result for the area to be changed. Also, as a result of the merging, the apparatus 100 can generate the change history information. In this case, the change history information may include an image of the area in which the change is extracted in the first area, and an image of the predetermined area in the second area.

Referring to FIG. 7, the change history information 700 may include a first area 720 and a second area 710.

The first area 720 is an image generated as a result of image conversion for the to-be-changed area. The scheduled change area is a region to which a change is to be added on the content to be synchronized prior to synchronization of the content of the apparatus 100. [

The second area 710 is an image generated as a result of image conversion result image conversion for the area from which the change is extracted. The area where the change is extracted is an area on the terminal contents including the change relative to the content to be synchronized.

As the device 100 provides visualization information about the synchronization details, such as the change history information 700, the user can easily grasp the content of the change.

The change history information may be information mapped on the synchronized content.

Figure 8 is an illustration of content with changes added by synchronization that is referenced in some embodiments of the invention. 9 is an illustration of content in which some content has been deleted by synchronization referred to in some embodiments of the present invention.

According to the embodiment of the present invention, in step S40, the apparatus 100 may first divide the image conversion result for the scheduled change area into a plurality of areas. In addition, based on the first division result, the apparatus 100 may divide the image conversion result for the extracted region into a plurality of regions. The device 100 may compare the first and second divided results to identify the location of the change. That is, the device 100 may divide the generated image into two or more areas in the image conversion step S40.

8 shows an example in which the apparatus 100 first divides the image conversion result for the scheduled change area 810 of the synchronization target content 800 into three areas 811, 812 and 813. [ The apparatus 100 may divide the region according to a predetermined criterion. For example, the device 100 may divide an area by separable paragraphs.

8 shows an example in which the image conversion result for the extracted region 815 is divided into the four regions 811, 812, 813, and 821 by the second division. In particular, area 821 is shown as the area from which the changes were extracted.

The apparatus 100 can compare the three regions 811, 812 and 813 included in the region 810 with the four regions 811, 812, 813 and 821 included in the region 815. The device 100 may thereby identify the location of the area 821.

8, the area 821 is not included in the area 810, but is included only in the area 815. [ In this case, the device 100 can determine that the area 821 is added to the content by synchronization. The apparatus 100 may also detect that the position of the divided area 812 on the predetermined area 810 is changed to the position of the divided area 812 on the extracted area 815. [ Also, the apparatus 100 may determine that the area 821 is added to the position change difference. As the device 100 senses a change in the location of the area 812, it can identify the location of the change.

9 shows an example in which the apparatus 100 first divides the image conversion result for the scheduled change area 810 of the synchronization target content 800 into three areas 811, 812 and 813. [ 9 shows an example in which the image conversion result for the extracted region 817 is divided into the three regions 811, 812, and 910 by the second division. In particular, area 910 is shown as the area from which the changes were extracted.

The apparatus 100 can compare the three areas 811, 812 and 813 included in the area 810 with the three areas 811, 812 and 910 included in the area 817. The device 100 can identify that the area 813 has been changed from the terminal content to the area 910 with respect to the content to be synchronized.

9, region 813 is included only in region 810 and not included in region 817. [ In this case, the device 100 can determine that the area 813 has been deleted from the content by synchronization.

Based on the location of the region 813, the device 100 may sense the location of the change. Also, if an area other than the area 910 is detected at the position of the area 813, the device 100 can determine that the area 813 is deleted and other contents are filled. In this case, the apparatus 100 can sense the position of the change based on the position of the area 813. [

Figure 10 is an illustration of an example where the synchronization subject content referred to in some embodiments of the present invention is an image. If the content to be synchronized is image content, the change history information may include identification processing information on the change displayed on the synchronized image content.

In Fig. 10, an image 1000, which is the content to be synchronized, and an image 1020, which is the terminal content, are shown by way of example. The apparatus 100 may determine that the content 1025 of the image 1020 has been changed in relation to the content 1010 of the image 1000. [

In this case, the area from which the change is extracted may be the image 1020 itself. At this time, the apparatus 100 may skip the image conversion step S40 since the images 1000 and 1020 are already in the image state. At this time, the apparatus 100 can generate information on which the identification process for the change has been performed, as the change history information. That is, the apparatus 100 identifies the region 1030 from which the change is extracted, and maps the region 1020 to the image 1020 for storage.

11 is an example of a case where the content to be synchronized referred to in some embodiments of the present invention is a moving image. When the content to be synchronized is video content, the change history information may include changed frame information of the video content.

In FIG. 11, a frame 1100 of a moving image, which is a content to be synchronized, and a frame 1120 of a moving image, which is terminal content, are shown as an example. The apparatus 100 can determine that the frame of the terminal content is deleted as B and D with respect to the content to be synchronized with the moving image.

The device 100 can capture the image of the frames B and D of the frame 1100 by the image conversion of the scheduled change area of the content to be synchronized. Frames B and D are frames determined to be deleted by synchronization. Alternatively, the device 100 may capture a portion of the frame 1111 of the video, such as an image 1110. At this time, the frame 1111 may be a frame corresponding to a partial area 1112 of the playback bar.

With the image transformation of the region from which the changes have been extracted, the apparatus 100 can capture the image reproduced at the time of the frames B, D deleted from the synchronized content of the frame 1120. Alternatively, the device 100 may capture a portion of the frame 1131 of the video, such as an image 1130. At this time, the frame 1131 may be a frame corresponding to a partial area 1132 of the playback bar. At this time, the apparatus 100 can control to display the portions 1135 and 1137 corresponding to the deleted frames B and D on the playback bar after the frame 1131. The device 100 may generate the change history information using the images 1110 and 1130.

In the above description, the method of generating the change history information according to the synchronization of the contents has mainly been described. When the synchronization is performed, the user can identify only the changed part through synchronization through the change history information. If the synchronization is performed a plurality of times, the content may be changed more than the initial upload state. In this case, to assist the user in determining the change history, the device 100 may provide the user with a change trend of the content.

Figure 12 is an exemplary diagram for describing a change trend of synchronized content referenced in some embodiments of the present invention.

In step S50, the device 100 may receive a display request for change history information according to the synchronization progress from the user terminal 200. [ Upon receiving the request, the device 100 may provide an interface to the user terminal 200 that includes change history information. In particular, the interface is an interface for displaying change history information. At this time, the interface may include change history information generated as a result of one or more synchronization performed for a predetermined period.

In Fig. 12, the interface 1200 is shown as an example. The interface 1200 may include a menu 1210 for confirming a file of the synchronized contents, sharing the synchronized contents, generating the change history information, and storing the contents to be synchronized. In addition, the interface 1200 may include a menu 1220 for selecting a content file to check the trend of the change history.

The interface 1200 may include an area 1230 for displaying the change history information of each of the contents A, B, C,

Referring to FIG. 12, for example, when synchronization of content A is performed three times, A1, A2, and A3 may be generated as change history information. In addition, when the synchronization of the content B is performed twice, B1 and B2 may be generated as the change history information. In addition, when the synchronization with the content C is performed four times, C1, C2, C3, and C4 may be generated as the change history information. When the synchronization of the content D is performed only once, D1 can be generated as the change history information.

Observing the change trend of the change history information, the user can confirm the change trend due to the synchronization of the contents.

The change history information may be thumbnail information. Each thumbnail information may provide a link connection to information that can compare the change details, such as the change history information 700 shown in FIG.

The methods according to embodiments of the present invention described above with reference to the accompanying drawings can be performed by the execution of a computer program embodied in computer readable code. The computer program may be transmitted from a first computing device to a second computing device via a network, such as the Internet, and installed in the second computing device, thereby enabling it to be used in the second computing device. The first computing device and the second computing device all include mobile computing devices such as a server device, a fixed computing device such as a desktop PC, a notebook, a smart phone, and a tablet PC.

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, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
