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

Referring to FIG. 1, the content service providing system 10 according to the present embodiment includes a content database 11 and a user-specific content management database 12, and includes at least one or

more client terminals

21 and 22 through a network. In the drawing, only two terminals of the first and second client terminals are displayed for convenience of description). In addition, the content service providing system 10 may be configured to receive a content service providing request signal from the

client terminals

21 and 22 and to perform a content service according to the corresponding content service providing request signal. 13).

First, the content database 11 includes fingerprint information about the content. In addition, the content database 11 may contain various meta information such as the name of the content, copyright holder, performer, production year, time information, file format, other descriptive data, advertisement information, image size, image quality, codec information, etc. meta data) may be stored corresponding to each content and fingerprint information. In addition, each content may include address information indicating a location on the network. At this time, the size, image quality, and codec information of an image of content existing at a corresponding address may be stored according to the address information. In addition, all other data necessary for carrying out the present invention can be stored.

Here, the fingerprint information of the content refers to feature data indicating the characteristic of the content, and is also referred to as fingerprint data, DNA data, or genetic data. Regarding the fingerprint information, various methods have been proposed by the prior art, and since the fingerprint information can be easily determined whether the data is identical, it is widely used in the field of copyright management (DRM). For example, in the case of audio data, fingerprint information is generated using various characteristic data (eg, frequency, amplitude, etc.) representing the characteristics of the audio data, and in the case of video data, various characteristic data (eg, motion of a frame) of the video data are generated. Vector information, color information, etc.) to generate fingerprint information. The present invention is not intended for the method of generating the fingerprint information itself, and any form of fingerprint generation / extraction method according to the prior art may be used as it is, and thus the detailed description thereof will be omitted. Korean 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 (Determining Sameness of Video Data) And the same section detecting method and apparatus), 10-2007-0060978 (method and system for clustering video data with the same video data), 10-2007-0071633 (video data using video data cluster) Search service providing method and apparatus), 10-2007-0091587 (method and apparatus for setting and providing advertisement data using video data cluster), and 10-2008-0051688 (video processing method and apparatus), Describes a method of generating fingerprint data of audio or video data and a clustering method using such fingerprint data Applicant's fingerprint generation and extraction method may be used in the present invention, of course. In short, the present invention can use a fingerprint generation / extraction technique of a conventionally known content regardless of how the fingerprint information is generated / extracted from the content, and the content database 11 is generated by such a method. Fingerprint information of the content to be stored is stored corresponding to each content.

To this end, although not shown in the drawing, a separate content collector allows content and meta information to be collected from various sources (eg, UCC sites, file sharing sites, blogs, etc.) existing on the network, and fingerprints are extracted from these contents. May be stored in the content database 11.

In the present invention, the content may be audio data such as an mp3 or wav file format, or may be video data such as an avi or mp4 file format.

Meanwhile, the content database 11 may include address information of a web site that allows a user to purchase or download the corresponding content corresponding to each content.

Referring to FIG. 2, it can be seen that a content ID is assigned as '5' as an identifier for identifying content, and that fingerprint information is included as binary data. The fingerprint information herein refers to overall fingerprint information for the entire content. Next, it can be seen that various meta information such as content name, copyright holder, performer, production year, creation date, file format, time information, description data, and the like are stored for the corresponding content. In addition, it can be seen that the advertisement information includes the file name (adv15.mp4) of the advertisement information set corresponding to the content and the name of the advertisement information (Coca-Cola). Here, of course, the advertisement information may include the text data itself. It also includes information (www.content.com) that indicates the location on the network from which the content can be purchased or downloaded. In addition, three pieces of address information indicating a location of the corresponding content on the network are included, and it can be seen that image quality and codec information are stored corresponding to each of the address information. As a result, the image quality and codec information of the content existing in the corresponding network can be grasped and address information corresponding to the image quality and codec information corresponding to the terminal characteristic information of the client terminal can be retrieved as described later. .

Referring back to FIG. 1, the content service providing system 10 includes a content management database 12 for each user, and the content management database 12 for each user provides service-related information of content for which a user is provided with a service for each user. Save it. In this case, the service related information of the content may include location information of the final viewing of the corresponding content in the client terminal. The last viewing location information means, for example, location information at a time point corresponding to 30 minutes when viewing content from 0 second to 30 minutes through the client terminal when the content is composed of 1 hour in total time. This may be based on the time axis or may be generated based on fingerprint information. For example, when the user stops watching the content until 30 minutes by using the client terminal, the client terminal or the content service providing system 10 partially fingerprints the section of the time interval within a certain range based on the point in time. The information can be extracted and used as location information. Here, the partial fingerprint information means that the fingerprint information as described above is generated and extracted for a predetermined section.

In addition, the user-specific content management database 12 may be configured to further include fingerprint information of the content that the user is provided with the service. Since the fingerprint information herein is the fingerprint information as described above, detailed description thereof will be omitted.

In addition, the service-related information may further include address information indicating a location of the corresponding content on the network, which may be generated and stored with reference to the content database 11 as described above. Reference to the content database 11 may be made based on fingerprint information of the corresponding content stored in the user-specific content management database 12. In addition, the service-related information may further include content purchase information on whether the user has purchased the corresponding content. For example, when a user purchases or downloads the content instead of simply watching the content, the information may be stored in the user-specific content management database 12 so that the user can be authorized as a legitimate buyer.

Meanwhile, in FIG. 1, the content management database 12 for each user is shown as being provided in the content service providing system 10, but the content management database 12 for each user is provided in each of the

client terminals

21 and 22. You can also In this case, each of the

client terminals

21 and 22 is preferably configured to automatically synchronize when connecting to the content service providing system 10 side.

3 is a diagram illustrating an example of a user-specific content management database 12. Referring to FIG. 3, an ID for identifying a user is stored, and a content ID and fingerprint information are stored in the same manner as in FIG. It can be seen that. It can also be seen that the final viewing position is included as time information on the time axis. In this case, the final viewing position may be configured by using the partial fingerprint information as described above. In addition, the number of viewing information is also included, and information indicating whether or not the corresponding content is purchased. In addition, address information indicating a location on the network where the corresponding content exists is stored, which may be configured to synchronize with reference to the content database 11 configured as shown in FIG. In FIG. 3, the image quality / codec information is also included and stored according to each address information. However, this may be omitted. The content management database for each user of FIG. 3 is exemplary, and as described above, the fingerprint information, the number of viewing, and the address information may be omitted.

Referring back to FIG. 1, the content providing system 10 includes a content service providing unit 13, and the content service providing unit 13 operates as follows. First, the content service for the corresponding content is provided according to the first content service providing request signal from the first client terminal 21 which is one of the client terminals. Here, the content service may be a service that enables the corresponding content to be viewed on the client terminal or provides information related to the corresponding content. As described above, since the content database 11 includes address information for each content indicating the location where the content exists on the network, the content database 11 transmits the address information to the client terminal 21 so that the client terminal 21 corresponds. The contents can be directly provided by using the address information, or the content service providing system 10 can access the corresponding address information and receive the contents while transmitting the contents to the client terminal 21. As described above, when the first client terminal 21 stops watching the content, for example, while providing the content service, location information (see FIG. 3) where the content was finally viewed is service-related content management database for each user. Save it to (12). At this time, fingerprint information of the corresponding content may also be stored. Next, when the second content service providing request signal is received from the second client terminal 22 which is one of the client terminals, the content service is provided to the second client terminal with reference to the stored service related information and fingerprint information. Will be provided. In this case, the service-related information may refer to the above-described final viewing position information. In this case, the user may provide the content to the second client terminal 22 from the next time after the last viewing position based on the final viewing position information. In the case of stopping while watching, the user can be provided with a service to play using another client terminal.

In FIG. 1, the

client terminals

21 and 22 may be the same device or different devices. For example, when the first client terminal is a computer, the second client terminal may be a mobile communication terminal such as a smartphone. In addition, both the first client terminal and the second client terminal may be the same computer or mobile communication terminal. As a result, the distinction between the first client terminal 21 and the second client terminal 22 means that the content reproduction apparatus is used by the same single user at different times.

Next, the content service providing system 10 receives a second content service providing request signal from the second client terminal 22, which is one of the client terminals (S140). As described above, the second client terminal 22 may be the same device as the first client terminal 21 or may be a physically different device.

Meanwhile, the second content service providing request signal may include terminal feature information of the second client terminal 22, and the terminal feature information is software used when playing content in the second client terminal 22. Or it means hardware resource information. For example, the information may include information such as the resolution of the display device of the client terminal, the type and version of the playback software, the presence or absence of a codec, and the like.

Next, the content service providing system 10 refers to the stored service related information and fingerprint information (S150), and provides the content service to the second client terminal 22 according to the referenced information (S160). In the step S150, the corresponding content is first determined by referring to the service related information and the fingerprint information, and the position to play the corresponding content is determined based on the final viewing position information included in the service related information. At this time, the location on the network most suitable for playing the content in the second client terminal 22 from the content database 11 based on the terminal characteristic information of the second client terminal 22 transmitted in the step S140. Search for address information, and transmit the address information to the second client terminal 22 to access a web site on the network corresponding to the address information received by the second client terminal 22 to play the content. You can get services. Meanwhile, the content service providing system 10 retrieves address information indicating a location on a network suitable for playing the corresponding content in the second client terminal 22 from the content database 11 with reference to the terminal feature information. The content service may be provided by accessing a web site on the network corresponding to the address information, requesting a reproduction service for the corresponding content, and transmitting the received content data to the second client terminal.

In operation S160, the content service may be provided to the second client terminal 22 with reference to the content purchase information together with the stored service related information and fingerprint information. This means, for example, that if the user is the owner who purchased the content, if the content is directly stored, the content is transmitted to the second client terminal 22 or provided by referring to another location on the network.

According to the embodiment of the present invention described above, even when a plurality of different client terminals are used, the user can freely perform the play / stop function at a desired time point without having to store the contents to the corresponding terminal, respectively. Playback from another terminal can be made immediately from the point of view. In addition, according to the present embodiment, even when the user purchases the content, there is no need to store the content to the terminal, and all the management of the content can be performed based on the fingerprint information.
