The present embodiments are merely provided to complete the disclosure of the present invention and to fully inform the scope of the invention to those skilled in the art, and the present invention is defined by the scope of the claims. It will be. Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals refer to like elements throughout.

1 is a diagram illustrating a digital content sharing system according to each component according to a first embodiment of the present invention. As shown in FIG. 1, the digital content sharing system according to the present embodiment includes a pair of user terminals 110 and 120 having a short range wireless communication function and a wireless data communication function, and sharing digital content therebetween. It is configured to include a management server 200 for managing a series of processes for. The CP server 300 does not directly communicate with the user terminals 110 and 120. An internal configuration of the user terminals 110 and 120 is illustrated in a block diagram in more detail in FIG. 2, and an internal configuration of the management server 200 is illustrated in FIG. 3. Hereinafter, the configuration and operation of the digital content sharing system according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

The user terminals 110 and 120 illustrated in FIGS. 1 and 2 include an NFC module 102 and an NFC touch unit 101. When the user terminal 120 approaches the user terminal 110 and the distance between the NFC touch unit 101 built in each of the two user terminals 110 and 120 is within a predetermined distance, for example, within 10 cm, the two user terminals 110, Near field communication (120) is connected (hereinafter referred to as "NFC connection"), the NFC module 102 of the two user terminals (110, 120) to provide advance information for setting up the wireless data communication connection will be described later You can send and receive.

When the above process is referred to as 'NFC tagging', NFC tagging may be performed while digital content is selected or reproduced in the user terminal 110. For example, when the user terminal 120 approaches the user terminal 110 while a movie or a sound source is being played, an e-book or game is being executed, or a specific content is selected, the user terminal 120 is located between the two terminals 110 and 120. When the NFC connection is started, a series of processes for content sharing, which will be described later, may be started.

When NFC tagging is started, the NFC module 102 of the two terminals 110 and 120 transmits and receives prior information necessary for performing wireless data communication between the two terminals 110 and 120 through the NFC connection. At this time, the dictionary information transmitted and received between the two terminals (110, 120) is a series of information for wireless data communication connection, such as MAC address, IP address, port number of the user terminal 110 and / or user terminal 120 It may include. Through this process, it is possible to set up a wireless data communication connection between the two terminals (110, 120) for the transmission and reception of content to be described later. When the wireless data communication connection is set up, transmission and reception of digital content is possible between the two terminals 110 and 120 in a peer-to-peer (P2P) manner. The wireless data communication connection may be implemented in a Wi-Fi Direct or TransferJet manner, and FIG. 2 illustrates that the Wi-Fi Direct module 103 is built in the terminals 110 and 120 to illustrate the Wi-Fi Direct implementation. If a wireless data communication connection of the transfer jet method is used, the Wi-Fi Direct module 103 may be replaced with the transfer jet module. For reference, when the wireless data communication connection is implemented by the Wi-Fi direct method, the user terminal 110 which transmits the digital content may perform a function of a software access point (AP) by a method described below.

On the other hand, when the terminal 110 is playing or selecting specific content, and the terminal 120 wants to receive the corresponding content through the wireless data communication connection, first the copyright state of the specific content is passed through a predetermined copyright reading module. Can be read. In this case, for example, the header portion of the specific content may be analyzed and read. The predetermined copyright reading module may analyze the header portion of the specific content to read whether the corresponding content is a work. When the corresponding content is read as a copyrighted work, the terminal 120 to receive the digital content must be approved for sharing the digital content prior to the transmission and reception of the digital content between the two terminals 110 and 120. To this end, the terminal 120 receives identifier information (eg, Melon0001) of digital content to be shared from the terminal 110 through a wireless data communication connection. Identifier information is a concept including information about the provider of the digital content, DRM information, content classification, content unique identifier code, etc. This identifier information may be included in the content header, which is in the form of a hash code (Hash Code) May be stored as part of a media file.

The user terminal 120 transmits the identifier information received from the user terminal 110 through the Wi-Fi direct module 103 to the management server 200 through a wired or wireless Internet connection. As shown in FIG. 3, the management server 200 includes a payment manager 201 and an approval information manager 202. The payment manager 201 receives digital content identifier information from the user terminal 120, retrieves digital content corresponding to the received identifier information, and transmits a payment request for the digital content to the user terminal 120. When the electronic payment is completed by the payment module 104 of the user terminal 120, the approval information manager 202 transmits the shared approval information to the user terminal 120. The sharing approval information may be transmitted in the form of a message including a series of data of the contents approved, authenticated or allowed to transmit the digital content that has been paid from the user terminal 110 to the user terminal 120. When the approval information manager 105 of the 120 receives the shared approval information from the management server 200, the process of receiving data of the corresponding digital content from the user terminal 110 may be started through an IP check. The digital content data is transmitted and received in a P2P manner through a wireless data communication connection by the Wi-Fi Direct module 103 of the two terminals 110 and 120. Meanwhile, for this purpose, the user terminal 120 may transmit sharing approval information to the user terminal 110, and the user terminal 110 which has confirmed this may transmit digital content data to the user terminal 120. In detail, after the terminal 120 transmits the approval information received from the management server 200 to the terminal 110, the terminal 110 reads whether the approval information is legitimate by the predetermined authenticity reading module. If the approval information is read as legitimate, the terminal 120 may start the process of receiving the corresponding content from the terminal 110.

According to the first embodiment described so far, the user terminal 120 that wants to receive digital content data communicates with the management server 200 to approve sharing of the digital content, and also performs electronic payment related to the digital content.

However, this embodiment may be modified in various forms. For example, FIG. 4 relates to a second embodiment of the present invention. Referring to FIG. 4, the management server 200 is not a user terminal 120 but a user terminal. In step 110, the sharing approval information is transmitted. In this case, the shared approval information sent by the approval information management unit 202 is received by the approval information management unit 105 of the user terminal 110, and the user terminal 110 receives the sharing approval information to the user terminal 120. Start digital content data transmission. In this case, unlike the above description, a process of transmitting the sharing approval information from the user terminal 120 to the user terminal 110 or a process of reading the authenticity may be omitted.

Meanwhile, according to the first and second embodiments of the present invention, the delivery of the identifier information of the digital content to the management server 200 may also be directly performed by the user terminal 110 instead of the user terminal 120. (However, in FIG. 1 and FIG. 4, only one case is shown for convenience). In particular, according to the second embodiment of the present invention, since the terminal 110 receives a payment request from the management server 200, the user of the terminal 110 wants to present a specific digital content to the user of the terminal 120. When such a configuration may be possible. That is, when the digital content is being played on the user terminal 110 or when the user terminal 120 is set up in the selected state and the wireless data communication connection is set up through the NFC connection, the user terminal 110 directly manages the server 200. ) May transmit the identifier information of the corresponding digital content and pay later for the user terminal 120.

Meanwhile, FIG. 5 relates to the third embodiment of the present invention, in which the CP server 300 directly communicates with the terminal 120. Here, the CP server 300 means a content providing server, but in a broad sense it will be referred to as a concept including an SP server, that is, a service providing server.

Hereinafter, in describing the third embodiment of FIG. 5, differences from the first embodiment of FIG. 1 will be mainly described.

Referring to FIG. 5, prior to data transmission and reception between two terminals 110 and 120, the terminal 120 transmits identifier information (eg, Melon0001) of digital content reproduced or selected by the terminal 110 through a wireless data communication connection. Receive. Thereafter, the user terminal 120 transmits the identifier information received from the user terminal 110 through the Wi-Fi direct module 103 to the management server 200 through a wired or wireless Internet connection, the payment of the management server 200 The management unit 201 receives digital content identifier information from the user terminal 120, retrieves digital content corresponding to the received identifier information, and transmits a request for payment of the digital content to the user terminal 120. For reference, in the present exemplary embodiment, the present invention may be applied to a case in which the digital content reproduced or selected by the user terminal 110 is reproduced in a streaming form.

Then, when the electronic payment is completed by the payment module 104 of the user terminal 120, the approval information management unit 202 transmits the shared approval information to the CP server (300). The CP server 300 receiving the sharing approval information may perform a function of transmitting the payment-completed digital content to the user terminal 120. In this case, the process of transmitting the shared approval information from the user terminal 120 to the user terminal 110 or the process of reading the authenticity may be omitted, and the process of transmitting the content to the user terminal 120 by the user terminal 110. May also be omitted. However, the user of the user terminal 120 may feel as if the content that was being played on the user terminal 110 is directly transmitted from the user terminal 110.

Meanwhile, FIG. 6 is related to the fourth embodiment of the present invention, except that the CP server 300 directly communicates with the terminal 120 as in the third embodiment.
