In addition, the present invention can reduce the load on the server used for the content sharing service and utilize the personal computer to facilitate the maintenance of the service provider's facilities and reduce the maintenance cost.

The above objects, features, and advantages will be described in detail with reference to the accompanying drawings, whereby those skilled in the art to which the present invention pertains may easily implement the technical idea of the present invention. In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

In the present invention, 'content' is a term used to mean a general document, a web page, a web catalog, a text, a chat, an image file, a video and a multimedia file, and an internet UCC video.

In addition, in the present invention, the terminal is wirelessly communicated while being carried by an individual, such as a wired terminal and a personal mobile communication terminal (PCS), a personal digital terminal (PDA), a smartphone, a next generation mobile communication terminal (IMT-2000), etc. using a PSTN. This is a term in the sense of including a possible terminal, including a recently released VoIP terminal.

1 is a diagram illustrating an overall network of an embodiment to which a content sharing method according to the present invention is applied.

In FIG. 1, a caller who owns the calling terminal 102 wishes to share specific content before or during a call with a called party having the called terminal 104. In order to share content, it is necessary to first prepare content. For example, if the sender wants to share an image file or a video file, these files should be stored in the personal computer (PC) 100 in advance. Here, the difference from the prior art is that a process of uploading contents for sharing to a server provided by a service provider is not necessary. Instead, the sender records the list of contents that he or she wants to share with the content list management server 108. This list is used later when the calling terminal 102 selects content to share with the called terminal 104.

Shared session server 106 includes a billing server 106a and a shared platform (SIP) 106b. The shared session server 106 generally includes the ability to connect calls between the calling terminal 102 and the called terminal 104 and to maintain / manage the connected session.

The billing server 106a performs a function of checking a call start time, call end time, and other additional service use time of the calling terminal 102 and the called terminal 104 to calculate a service usage fee.

The sharing platform 106b receives a session sharing request for content sharing from the calling terminal 102 and sends it to the called terminal 104, and when the called terminal 104 sends a response message to this request message, it receives it. It serves to deliver to the calling terminal (102). In this process, the round trip message may use various protocols, but in one embodiment of the present invention, Session Initiation Protocol (SIP) is used.

For reference, the content list management server 108 is illustrated separately in FIG. 1, but it is assumed that the content list management server 108 may be used in a platform other than the shared platform 106b. Therefore, the content list management server 108 may be implemented in a form included in the shared session server 106. Alternatively, the content list may be stored in the personal computer 100 so that the personal computer 100 may serve as the content list management server 108.

2 is a flowchart illustrating a process of an embodiment to which a content sharing method according to the present invention is applied.

First, the personal computer 100 that stores the content to be shared registers the content (200). There may be various ways of registering. For example, as mentioned above, there may be a method of storing contents to be registered in the content list management server 108 in a predetermined list. Alternatively, the personal computer 100 may take the role of the content list management server 108 by storing a content list to be shared on the personal computer 100 itself. In FIG. 2, it will be described on the assumption that the personal computer 100 serves as the content list management server 108.

The content list may include location information on a memory such as a content file, for example, an image file or a video file, or may be an internet address where the UCC video is located when the content is an Internet UCC video. The stored content list may be provided to the user in order to obtain information about the content at any time as well as during the content sharing process according to the present invention.

After the registration process, the calling terminal 102 selects the content to be shared before or during the call (202). In this case, the personal computer 100 may transmit the registered content list to the calling terminal 102, and the transmitted list may be transmitted to the calling terminal 102 through display means of the calling terminal 102, for example, a liquid crystal display. Is displayed. The user can select the content he wants to share from the displayed content list.

The selected content list is transmitted back to the personal computer 100, and the personal computer 100 displays location information in memory of the selected content and access information of the personal computer 100, for example, an IP address of the personal computer 100, and the like. It provides to the calling terminal (102).

The originating terminal 102 now requests the sharing session server 106 to share the session for sharing the selected content. As mentioned above, since one embodiment of the present invention uses SIP, the originating terminal 102 forwards the SIP sharing request message to the sharing session server 106 requesting session sharing (206). At this time, the SIP sharing request message sent by the calling terminal 102 includes information on the called terminal 104 to which the contents are to be shared (for example, the IP address of the called terminal 104, if the called terminal 104 is a VoIP phone). Information about the content to be shared with the user, and location information about the personal computer 100 in which the content is stored (for example, an IP address of the personal computer 100).

The sharing session server 106 that has received the SIP share request message communicates the request for sharing of the originating terminal 102 by forwarding the message to the called terminal 104 (208). If the destination terminal accepts the sharing (not shown in the figure), the sharing session server 106 now provides location information for the personal computer 100 whose content is stored for content sharing between both terminals 102 and 104. Is transmitted to both terminals (102, 104) as a SIP message (210, 212). The SIP message may include a connection command to the personal computer 100.

Now both the calling terminal 102 and the called terminal 104 access the personal computer 100 for content sharing. At this time, there may be various ways to connect. For example, there may be a method of accessing the personal computer 100 through a shared client (program) pre-installed in both terminals 102 and 104. Although not shown in the drawing, in the access process, both terminals 102 and 104 may store information including the type, model, or specification of each terminal together with location information (for example, an IP address) of each terminal, and the like. ) Can be sent.

Both terminals 102 and 104 now request to transmit content to be shared while in or connected to the personal computer 100 (214 and 218). The personal computer 100 having received the content transfer request may transmit the content immediately after accepting the request, but here, the content conversion 216 is performed. This is because the data transmission speed may be different for each terminal. In particular, the content reproduction capability may be different for each terminal when the content is an image file or a video. Therefore, the personal computer 100 converts the content according to the capacity of each terminal in consideration of the type, model or specification information of each terminal received in the connection process of both terminals (102, 104) (216). This conversion step 216 may use a variety of existing content conversion methods, that is, various video encoding, streaming techniques and the like. For example, if the content is a UCC video on the Internet, the personal computer 100 may convert the UCC video through real-time transcoding after receiving the video in its own memory.

The personal computer 100 now transmits the converted content to the terminals 102 and 104 in real time (220 and 222). The calling terminal 102 and the called terminal 104, which have received the content, display the received content on display means, for example, a liquid crystal screen, while maintaining the call. This allows the caller and the called party to continue talking while sharing the content with each other.

3 is a block diagram showing the configuration of a content sharing apparatus according to the present invention. The content sharing apparatus 300 according to the present invention includes an input unit 300a, a message transceiving unit 300b, and a content requesting unit 300c.

The input unit 300a receives information about content that the user wants to share. For example, when a user is provided with a list of pre-registered contents, the input unit 300a may receive information about contents to be shared by allowing the user to select contents to be shared from the contents list. Alternatively, content information included in a sharing session request message to be described later may be extracted and received as it is.

The message transmitting and receiving unit 300b transmits a sharing session request message including content information received from the input unit 300a to the sharing session server, and receives a response message for the sharing session request message from the sharing session server. . The message used in the message delivery bride 300b may vary depending on the type of protocol. In addition, the sharing session request message may include not only input content information but also various other information such as a storage location of the content and information on the called terminal. Therefore, the message transceiver 300b may include a function of processing and interpreting a message including such information.

The content requesting unit 300c stores the content based on the content information received from the input unit 300a and the storage location information of the content included in the sharing session request message by the message transmitting and receiving unit 300b, for example, for personal use. It serves to request the transmission of the content to the computer (100). When requesting content, the content request unit 300c may not only transmit a message for requesting content but also transmit other information, for example, information such as the type, model, or specification of a terminal to accommodate the content. will be.

In addition, although not shown in the drawing, the content sharing apparatus 300 according to the present invention may further include other functions required for content sharing, such as a function of receiving the requested content and a function of displaying the received content.

4 is a flowchart illustrating a flow of a content sharing method according to the present invention.

First, information about content to be shared with the counterpart terminal is received (400). This information can take many forms (e.g., computer IP address or memory address) and can also be entered in various ways (e.g., how to select content to share from a given list). This step 400 may be prior to the caller and the called party, or may be busy.

In operation 402, a sharing session request message is transmitted to the sharing session server to share the content with the counterpart terminal using the content information received in operation 400. In this process, the sharing session request message may include not only the input content information but also various other information such as a storage location of the content and information on the called terminal.

Then, a response message to the transmitted sharing session request message is received from the sharing session server (404). If the response message contains content allowing sharing for the sharing session request, then request 406 is sent to the location where the content to be shared is stored, for example to a personal computer.

When the personal computer requested to transmit the content transmits the content, the content sharing method according to the present invention is completed by receiving the content (408). In this case, the content received from the personal computer may not have undergone any conversion process, or may be content that has undergone a series of conversion processes by the personal computer.

According to the method and apparatus of the present invention, by using a personal computer to share the content in real time before or during a voice call, it is possible to provide the user with a more stable content sharing service than the existing server-based sharing method have. In addition, in terms of the service provider, it is possible to reduce the load on the server used for the content sharing service and to utilize the personal computer to facilitate the service provider's facility maintenance and reduce the maintenance cost.

The method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention. The recording medium includes all types of computer-readable recording media (tangible media such as CD and DVD as well as intangible media such as carrier waves).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by.
