The present invention relates to a data transmission method, a server, and a data transmission system, and more particularly, to a shared data transmission method, a server, and a shared data transmission system for sharing data with other devices.

Recently, according to the rapid development of electronic engineering, communication engineering, and terminal technology, mobile terminals have various functions. That is, as the wireless communication and data processing technology rapidly develops, people can use functions of not only voice communication but also content reproduction and wireless Internet access by using mobile terminals.

However, the mobile terminal is characterized in that it can guarantee the mobility of the user by overcoming the stability which is the greatest disadvantage of the personal computer (PC: Personal Computer), while the light weight and the miniaturized design greatly restrict the central processing unit, There is a drawback to receiving. Accordingly, it may be difficult for the user to simultaneously perform search and playback of contents or data using the mobile terminal.

Accordingly, it is possible to pre-select / search desired data using a device that does not greatly restrict the use of a central processing unit, a memory, a battery, etc., and then enjoy only selected / retrieved data through the mobile terminal, There is a need for separating the search job from the playback job, for example, previewing / searching in advance and listening to data selected / searched by the user through other terminals.

However, in order to separate the retrieval and reproduction of data, smooth sharing of data must be supported. In other words, for one piece of data to work and process on each of two devices, one piece of data has to be shared in two devices in an easier and more convenient way. In addition, since the specification of the two devices and the working environment in the two devices are different from each other, it is necessary to process the data in consideration of these specifications and the working environment.

Accordingly, it is required to search for measures to share the data.

Hereinafter, the present invention will be described in more detail with reference to the drawings. In particular, FIGS. 1 and 20 illustrate a data transmission system according to embodiments of the present invention. In FIGS. 3 to 17, shared data such as registration of devices, shared data transmission, Will be described. Specific configurations of devices and servers constituting the data transmission system will be described with reference to FIGS. 18 and 19. FIG.

<Overview of data transmission system>

1 is a diagram illustrating a data transmission system according to an embodiment of the present invention. The data transmission system according to the present embodiment selects a desired data among a plurality of data stored in one device and allows the selected data to be shared in another device. In addition, the data transmission system according to the present embodiment transfers shared data to a connected device when the device is connected to the server.

The data transmission system includes a mobile phone 110, a PC 120, a notebook computer 130, a digital camera 140, a TV 150, and a server 200, which are user terminals.

The mobile phone 110, the PC 120, the notebook 130, the digital camera 140, and the TV 150, which are user terminals, transmit data stored in each device to the server 200 in addition to their respective roles , So that the transmitted data is shared by other devices.

For example, the mobile phone 110 transmits web pages retrieved through web surfing to the server 200, allowing web pages to be stored in the server 200, and one of the other devices connected to the server 200 The PC 120 can call and display the web page stored in the server. The digital camera 140 transmits the photo data photographed by the digital camera 140 to the server 200 so that the photo data is stored in the server 200 and one of the other devices connected to the server 200 The TV 150, which is a server, can call and display the photo data stored in the server 200. [

Of course, the shared data may include all the data generated in each device or received by each device, such as video, voice, address book, telephone number, and Internet search result, as well as the above-mentioned pictures and web pages.

As described above, the server 200 stores the shared data received from each device through the network, and transfers the shared data to each device accessed through the network.

The server 200 analyzes the information about the devices accessing the server 200 and determines whether to allow access of the devices based on the analyzed information for the devices.

Here, the information on the device is a concept including the device's own information (hereinafter collectively referred to as &quot; device information &quot;) and user information using the device. The device information includes device manufacturer information, type information, MAC address information, profile information, and the like. In addition, the user information includes access authority information, security information, user preference data, and the like for the server 200.

The manufacturer information is identification information for the manufacturer of the device, and the breed information is identification information for indicating the type of the device. The MAC address information is inherent identification information determined for each communicatable device. Profile information is a concept of collectively collecting information about authentication and accounting for devices, services used by devices, and communication networks to which devices belong.

The access right information is information on whether or not the device is authorized to access the network or the server, and the security information is information on the security status of the device. The preference data information is information on data preferred by a user who uses the device.

For example, the server 200 may determine that the devices connected to the server 200 are manufactured by the same company based on the device information of the devices connected to the server 200, If the user of the server 200 determines that the user of the server 200 is authorized to access the server 200,

In addition, the server 200 stores in advance information on data that the user using the TV 150 prefers to receive via the TV 150, and stores only the user's preferred data among the shared data on the TV 150 150). The preference data information may be generated in consideration of the usage history of the TV 150, the details of access to the server 200 through the TV 150, and the details of the received data.

On the other hand, the server 200 checks whether updated shared data exists in the server 200, and when there is a device accessing the server 200, the server 200 provides the updated shared data when the device 200 accesses the server 200 . Thus, the reason why the device provides the shared data when accessing the server 200 is that the meaning of connecting the device to the server 200 implies that the user intends to use the device. That is, the server 200 determines the intention of the user to use the device based on whether or not the device is connected to the server 200, and transmits the shared data to the device to be used by the user. The process of transmitting the shared data when connected to the server 200 will be described later in detail.

Meanwhile, as described above, the server 200 provides the shared data to the devices accessing the server 200 based on the device information and the user information of the device. However, in order for the shared data to be transmitted and received in a more seamless environment, each of the devices needs to be registered in the server 200. [ It is possible to provide the shared data even if the device is not registered in the server 200. However, in the case of providing the shared data to the registered device, it is possible to perform a simpler and simpler authentication and to provide a customized service for the registered device There will be.

Hereinafter, a process of registering a device in the server 200 will be described with reference to FIG.

<Registration of device>

2 is a flowchart illustrating a device registration process according to an exemplary embodiment of the present invention. In FIG. 2, it is assumed that the mobile phone 110 is registered in the server 200 for convenience of explanation.

The mobile phone 110 transmits a 'device registration request' for the mobile phone 110 to the server 200 in order to register the server 200 in the server 200 (S310). The server 200 receives the 'device registration request' for the mobile phone 110 and transmits 'device information and user information request' to the mobile phone 110 for determining whether device registration is possible (S320) . In response to the 'device information and user information request', the mobile phone 110 transmits 'device information and user information' to the server 200 (S330).

As described above, the device information includes manufacturer information, type information, MAC address information, and profile information of the mobile phone 110. The user information includes access right information, security information, and user preference data of the mobile phone 110 to the server 200.

The server 200 determines whether registration of the mobile phone 110 is possible based on device information and user information received from the mobile phone 110, that is, whether the received information is valid for registration of the mobile phone 110 (S340).

If the registration is impossible (S340-N), the server 200 informs the mobile phone 110 that the mobile phone 110 can not be registered (S350) The mobile phone 110 registers the mobile phone 110 in the server 200 and stores information received from the mobile phone 110 in step S370.

By registering the mobile phone 110 in the server 200 as described above, the authentication process for the mobile phone 110 can be largely omitted, so that the shared data generated or received from the mobile phone 110 can be easily and quickly transmitted to the server 200. [ (200). In addition, by registering the mobile phone 110 in the server 200, a customized service for the mobile phone 110 becomes possible, and when shared data is transmitted to the mobile phone 110, It is possible to provide optimized shared data.

3 is a view showing a list 400 of devices registered in the server 200. As shown in FIG. As shown in the figure, the server 200 manages the 'registered device list 400' so that when the devices included in the 'registered device list 400' are connected, the server 200 can easily and conveniently transmit and receive the shared data .

Of course, in FIG. 3, only the product name of the device is listed in the 'registered device list 400', but in the 'registered device list 400' of the server 200, Will be stored together.

<Shared data transfer>

Hereinafter, a basic process of transmitting the shared data will be described with reference to FIG.

4 is a diagram for explaining a shared data transmission process according to an embodiment of the present invention. Hereinafter, the mobile phone 110 and the TV 150 will be described as an example.

The mobile phone 110 transmits the data 500 generated in the mobile phone 110 or received from the outside to the server 200 for sharing in another device. The reason why the mobile phone 110 transmits the data to the server 200 for sharing data is as follows.

First, for the convenience of visual provision of the data 500. In the mobile phone 110, due to the limited display size, it is difficult for a plurality of users to use the data 500 together. Accordingly, if the user desires to use the data 500 stored in the mobile phone 110 together with a plurality of other users, the user may store the data 500 in the server 200 and then call again through a large display such as the TV 150 .

Second, it is for the separation of the collection and processing of the data 500. Since the mobile phone 110 is generally carried and used by a user, there is an advantage that the mobile phone 110 can be used from time to time. On the other hand, there is a disadvantage that the size of the display is limited and the input of the user operation is inconvenient. Accordingly, the user may collect data from the mobile phone 110 at any time, store the data in the server 200, and collectively process the data stored in the server 200 using the PC 120 in the home.

Of course, the opposite case can be assumed. For example, a user who does not have enough time to use the TV 150 may save the data stored in the TV 150 to the server 200, and then use the mobile phone 110 by calling the user.

Third, it is for the management of the data 500. Devices are constrained to storage space for data, and can have data common to each device. Accordingly, the server 200 manages the data of each device in a comprehensive manner, thereby enabling the user to manage the data 500 easily.

In this way, the server 200 receives and stores the data 500 generated from the mobile phone 110 or received from the outside, and when the stored data 500 is called by the TV 150, 500 to the TV 150.

<Shared data transfer according to registration status>

On the other hand, in the above, it has been mentioned that data can be transmitted and received more efficiently when the device is registered in the server 200 in advance. Hereinafter, a concrete data transmission / reception process according to whether or not the receiving-side device is registered will be described with reference to FIGS. 5 and 6. FIG.

5 is a flowchart illustrating a method of transmitting a shared data according to registration.

The mobile phone 110 receives or generates data (S610) and determines whether to designate it as shared data (S620). If it is not designated as shared data (S620-N), it is determined whether a display command for data is input (S630). If a display command is input (S630-Y), it is displayed on the screen (S640).

On the other hand, if the data is designated as shared data (S620-Y), the mobile phone 110 transmits the shared data to the server 200 (S650).

The server 200 stores the shared data received from the mobile phone 110 and designates it as updated data (S660). If it is determined in step S670 that a connection is attempted from the TV 150, it is determined in step S680 whether the TV 150 that has tried to access the server 200 is registered in the server 200 in advance.

If the TV 150 is not registered in the server 200 in step S680-N, the server 200 transmits 'device information and user information request' to the TV 150 (S690) Transmits the 'device information and user information' to the server 200 (S700).

Thereby, the server 200 registers the TV 150 in the server 200 (S710). Of course, this is merely a brief description of the registration process, and it is needless to say that the registration process may further include specific processes as shown in FIG.

If the TV 150 is registered in the server 200 in step S710 and the TV 150 is already registered in the server 200 in step S680-Y, And analyzes the rights and available services of the TV 150 based on the device information and user information received from the TV 150 or the device information and user information already received and stored from the TV 150 S720).

The reason for analyzing the authority of the TV 150 is that restrictions on sharing may be set by the mobile phone 110 providing the shared data. A more detailed description will be given later.

The reason for analyzing the available service of the TV 150 is that all the data may not be executed in all devices. Accordingly, the server 200 may determine the types of data that can be executed on the TV 150 based on the 'device information and user information', and only the data that can be executed on the TV 150 among the shared data is transmitted to the TV 150 send.

The server 200 also processes the selected data based on the device information and user information received from the TV 150 or the device information and user information already received and stored from the TV 150 (S730). Here, the processing of the data includes scaling the data at a resolution suitable for the TV 150 or adjusting the file size of the data so that there is no problem in being executed in the TV 150 and the like.

Thereafter, the server 200 transmits the processed data to the TV 150 (S740). The TV 150 displays the received data directly on the screen (S750).

Accordingly, the TV 150 receives the updated shared data as soon as it connects to the server 200 and displays it on the screen, thereby allowing the user to immediately view the updated shared data.

Meanwhile, in the above description, when the device connects to the server 200, it has been mentioned that the updated data is transmitted to the server 200 automatically. According to the present embodiment, data that is not executable on the TV 150 can not be transmitted to the TV 150 and can not be provided to the user. Accordingly, the server 200 monitors whether or not a device capable of executing the untransmitted data is connected to the server 200, and when another device connects to the server 200, the server 200 transmits the remaining untransmitted data to another connected device Lt; / RTI &gt;

FIG. 6 is a diagram showing a list 800 of devices registered in the server 200. FIG. As described above, the server 200 manages the 'registered device list 800' so that when the devices included in the 'registered device list 800' are connected, it is possible to transmit and receive the shared data more easily and conveniently .

In particular, as shown in FIG. 6, the server 200 extracts concrete information such as an authority level or a resolution for each device based on 'device information and user information', and transmits the concrete information to the ' Device list 800 'to be used for analyzing rights and available services for devices and for data processing.

<Shared data transmission according to line processing>

Hereinafter, a concrete data transmission / reception process according to whether shared data is processed in advance will be described with reference to FIGS. 7 and 8. FIG.

7 is a flowchart illustrating a method of transmitting shared data according to whether or not a line is machined.

The mobile phone 110 receives or generates data (S910), and determines whether to designate it as shared data (S920). If it is not designated as shared data (S920-N), it is determined whether a display command for data is input (S930). If a display command is input (S930-Y), it is displayed on the screen (S940).

On the other hand, if the data is designated as shared data (S920-Y), the mobile phone 110 transmits the shared data to the server 200 (S950).

The server 200 stores the shared data received from the mobile phone 110 and designates it as updated data (S960). Thereafter, the server 200 determines whether to process the updated shared data in advance before the device is connected to the server 200 (S970).

Whether or not to process in advance will depend on the settings entered by the user.

If it is set to be processed in advance (S970-Y), the server 200 processes the updated shared data for each device registered in the server 200. [ For example, when a mobile phone 110, a PC 120, a notebook 130, a digital camera 140, and a TV 150 are present as devices registered in the server 200, The mobile terminal 110 processes the updated shared data in a state optimized to be executed in the mobile phone 110 based on the device information and the user information received from the phone 110, And updates the shared data in a state optimized to be executed on the notebook 130 based on the device information and the user information received from the notebook 130 And processes the shared data. Further, the shared data updated in a state optimized to be executed by the digital camera 140 is processed based on the device information and the user information received from the digital camera 140, and device information received from the TV 150, And processes the updated shared data in a state optimized to be executed on the TV 150 based on the information.

If it is set to be processed in advance (S970-Y), the server 200 selectively processes the updated shared data for each device registered in the server 200. [ For example, in the case of data that is not executable on the TV 150, the server 200 does not process the updated shared data for the purpose of transmitting to the TV 150.

When the processing for the updated shared data is completed, the server 200 stores the processed data and waits until the devices connect to the server 200. [

Thereafter, when the TV 150 attempts to connect to the server 200 (S990), the server 200 is optimized to be executed on the TV 150 and transmits the processed data to the TV 150 (S1020) The TV 150 displays the received data on the screen (S1030).

For a detailed description, FIG. 8 will be referred to. 8 is a diagram showing a state in which shared data is processed for each device.

As shown, the mobile phone 110 transmits the captured data 1110 in the mobile phone 110 to the server 200 for sharing. At this time, the data photographed by the mobile phone 110 has a resolution of 800 * 600.

The server 200 processes the received shared data based on device information and user information received for each device. That is, when the digital camera 140 and the TV 150 are registered in the server 200, the resolution of the digital camera 140 is 1000 * 500, and the resolution of the TV 150 is 1920 * 1080, 200 scales the received shared data to a resolution of 1000 * 500 based on the device information and the user information for the digital camera 140, and based on the device information and user information for the TV 150, The received shared data is scaled and converted to a resolution of 1920 * 1080.

Thereafter, when the TV 150 connects to the server 200, the TV 150 transmits the processed data to the TV 150 in a resolution of 1920 * 1080.

Of course, changing the resolution at the time of processing is merely an example, and it can be said that processing is performed in this embodiment if it is changed so as to be optimized for execution in a device such as a file format change or a file capacity change.

On the other hand, if it is set not to process in advance (S970-N), the server 200 waits and stores the updated shared data intact until the devices connect to the server 200 without processing the updated shared data.

Thereafter, when the TV 150 attempts to connect to the server 200 (S990), the server 200 transmits the authority of the TV 150 and available services The shared data executable in the TV 150 among the updated shared data is selected (S1000), and the selected data is processed into a form optimized for the TV 150 (S1010).

The server 200 is optimized to be executed on the TV 150 and transmits the processed data to the TV 150 (S1020), and the TV 150 displays the received data on the screen (S1030).

As described above, it is possible to select whether to process the updated shared data in advance or in the future, and it has advantages and disadvantages which are opposite to each other. That is, when the updated shared data is processed in advance, there is an advantage that data can be transmitted to the device connected to the server 200 more quickly, whereas a disadvantage of storing a processed data per device consumes a lot of storage space have. Further, when the updated shared data is processed later, it has advantages and disadvantages opposite to those in the case of processing in advance.

<Shared data transfer according to sharing restriction>

On the other hand, it has been mentioned above that restrictions on sharing can be set. Hereinafter, a method of transmitting a shared data according to a sharing restriction will be described with reference to FIGS. 9 and 10. FIG.

9 is a diagram for explaining a shared data transmission method according to an embodiment of the present invention.

The mobile phone 110 receives or generates data (S1210) and determines whether to designate it as 'shared data restricted to the TV 150' (S1220). If it is not designated as shared data restricted to the TV 150 in operation S1220-N, it is determined whether a display command for data is input (S1230). If a display command is input (S1230-Y) S1240). It goes without saying that a process of determining whether or not to designate as shared data for a device registered in the server 200 in addition to the TV 150 may be added.

On the other hand, if the shared data limited to the TV 150 is designated (S1220-Y), the mobile phone 110 transmits the shared data restricted to the TV 150 to the server 200 (S1250).

The server 200 stores the data received from the mobile phone 110 and designates the updated data and the shared data restricted to the TV 150 (S1260). The server 200 analyzes authority and available services of the TV 150 on the basis of the device information and the user information previously received from the TV 150 on the shared data designated by the TV 150, The shared data is processed in a state optimized to be executed in step S1260.

Thereafter, when the TV 150 attempts to connect to the server 200 (S1270), the server 200 transmits the processed data to the TV 150 (S1280). Of course, since the processed data is shared data restricted to the TV 150, even if a device other than the TV 150 connects to the server 200, the server 200 does not transfer the processed data to another device .

Referring to FIG. 10, a detailed description of data stored in the server 200 according to the sharing restriction will be made. 10 is a diagram showing data 1300 stored in the server 200. As shown in FIG.

As shown in the figure, the server 200 stores updated data transmitted from the devices registered in the server 200. Of course, data already received from the devices and already shared with other devices can be stored as they are.

On the other hand, the server 200 stores information about sharing restriction setting of each data together with each data. For example, DATA 1 is data allowed to be shared with all devices, DATA 2 is data allowed to be shared only with the TV 150, DATA 3 is allowed to be shared with other devices except the TV 150, Lt; / RTI &gt;

As a result, data can be shared according to the user's selection, and the privacy of the user can be protected.

<Metadata-based Shared Data Selection>

Meanwhile, the data stored in the server 200 is stored based on the metadata. That is, the server 200 extracts metadata from the received shared data, and stores the extracted metadata together with the shared data. Accordingly, each device can input a keyword and select and search data to be transmitted to another device.

11 to 13 will be referred to for the explanation.

11 is a diagram for explaining a metadata-based shared data providing method. First, the server 200 stores the shared data received from the devices and extracts each metadata from the stored shared data (S1430). In addition, the server 200 stores the extracted metadata together with existing shared data (S1440).

This will be described with reference to FIG. 12 is a diagram for explaining the metadata extraction process.

As shown, when the shared data 1610 is transmitted from the mobile phone 110 to the server 200, the server 200 not only stores the received shared data 1610, but also stores the received shared data 1610 The metadata 1620 can be extracted and stored together.

In FIG. 12, metadata 'MOVIE' is extracted based on information on the genre of the received shared data 1610, metadata 'ET' is extracted based on the title information, It is assumed that the metadata 'OLD' is extracted as a basis.

Of course, any information that can be extracted through the shared data 1610 can be included in the metadata as well as the genre, title, creation date and time described above. Therefore, it may be extracted from the domain name or data of the web page in which the data constituting the symbol, number, figure, color or data exist.

Accordingly, as described above, each device can select and search data to be transmitted to another device by inputting a keyword.

11, when a keyword is input from the user through the mobile phone 110 in step S1410, the mobile phone 110 transmits the keyword to the server 200 in step S1420. In step S1420, The server 200 analyzes the metadata of the shared data stored in the server 200 and selects some of the stored shared data in operation S1450.

The server 200 analyzes the metadata based on the keyword, selects some of the registered devices (S1460), processes the selected data into a state optimized for the selected device, and stores the processed data (S1470).

Thereafter, the server 200 detects whether there is a device attempting to connect to the server 200, and when the TV 150 attempts to connect to the server 200 (S1480), the processed data and metadata are transmitted to the TV 200 (S1490), and the TV 150 displays the processed data on the screen (S1500). It goes without saying that the server 200 may transmit only the processed data to the TV 150 and not transmit the metadata to the TV 150. However, the case where the metadata needs to be transmitted together with the processed data will be described later with reference to Fig.

Meanwhile, a process of searching for and transmitting the shared data will be described with reference to FIG. 13 is a diagram showing a state in which shared data is retrieved and transmitted based on a keyword.

As shown, when a keyword 1710 'MOVIE', 'ET', or 'OLD' is input through the mobile phone 110 and transmitted to the server 200, the server 200 receives the received keyword 1710, And extracts the search result 1720 based on the search result.

If there is a transmission command for data retrieved from the mobile phone 110, the server 200 determines whether or not a device connected to the server 200 is present, 150 to the shared data 1730, which is the search result 1720. [

<Selection of shared data reception using UI>

The shared data generated or received by the mobile phone 110 is stored in the server 200 and the server 200 transmits the shared data to the TV 150 when the TV 150 accesses the server 200. [ As shown in FIG.

The reason why another device transmits the shared data when accessing the server 200 is because the user can see that the user uses the device only when the device connects to the server 200. [ That is, the present invention is intended to provide the convenience of providing the updated data only by the operation of accessing the server 200 without any user's operation, so that the user does not have to operate the updated data and check it.

However, since the devices in the home are not used by only one user, the user of the mobile phone 110 and the user of the TV 150 may be different. That is, there may be a case where the user who views the TV 150 connected to the server 200 and the user who checks the updated data in the TV 150 may be different.

In this case, the user for viewing the TV 150 can be disturbed by the original intention of viewing the TV 150 due to the confirmation of the updated data.

In order to prevent such a problem, it may be possible to inquire the user whether or not to display updated data received.

For reference, FIG. 14 will be referred to. 14 is a diagram for explaining a UI providing process for displaying shared data.

As shown, when the TV 150 attempts to connect to the server 200 (S1810), the server 200 transmits the stored shared data to the TV 150 (S1820).

At this time, since the user for allowing the shared data to be stored in the server 200 and the user for operating the TV 150 may be different from each other, the TV 150 has a UI for inquiring whether to display the received shared data (Step S1830).

If a display command is input from the user (S1840-Y), the TV 150 displays the received shared data on the screen (S1870) 150 are notified to the server 200 (S1850). Of course, the TV 150 may store the received shared data in the TV 150 or may delete the received shared data in the TV 150. [

On the other hand, since the shared data is not provided to the user, the server 200 searches whether another device is connected to the server 200 (S1860) and transmits the shared data to the device connected to the server 200. [

<Display of Shared Data According to Other Embodiments>

In the above description, it is mentioned that the metadata stored in the server 200 can be transmitted together with the device connected to the server 200. [ This will be described with reference to FIG.

FIG. 15 is a diagram for explaining how metadata transmitted together with shared data is displayed on the screen.

Referring to FIG. 15, a user retrieves a plurality of data from a plurality of Internet shopping malls through the mobile phone 110, and transmits the data to the server 200 to share a plurality of data. In the mobile phone 110, one of a plurality of data searched by the user is displayed.

When the user designates shared data, the data retrieved by the user is transmitted to the server 200 and stored in the server 200, respectively.

Meanwhile, the server 200 extracts metadata of each shared data from the received shared data, and stores the metadata together with the shared data. In FIG. 15, a product called 'BANANA' for $ 10 is searched in a shopping mall called 'B-Mall', and a screen for the search result is stored in the server 200 as shared data.

Accordingly, the server 200 can extract metadata such as 'B-mall' and 'Banana' from the screen of the received search result.

Likewise, the screen for the search result in the shopping mall called 'A-Mall' and the screen for the search result in the shopping mall called 'C-Mall' are extracted and stored together in the server 200 in the same way.

Thereafter, when the PC 120 connects to the server 200 by the user, the server 200 transmits the updated shared data to the PC 120. When the server 200 determines that the amount of data received from the mobile phone 110 is large or the data received from the mobile phone 110 are related to each other, the server 200 does not directly transmit the data to the PC 120, And transfers only the metadata to the PC 120. [

Accordingly, the metadata of the updated shared data can be displayed on a single screen on the screen of the PC 120, and the user can select and receive the desired data through the PC 120.

For example, when the search result retrieved from 'B-Mall' is to be provided as shared data, metadata related to 'B-Mall' among the metadata displayed on the screen can be selected, and 'B-Mall' When the related metadata is selected, the server 200 provides the PC 120 with the search result retrieved from the 'B-Mall' as shared data.

Accordingly, the same screen as that screened by the mobile phone 110 is displayed on the screen of the PC 120. [

By receiving and displaying the shared data specified through the mobile phone 110 from the server 200, data can be selected in advance in the moving environment, and data can be used more quickly in a more convenient environment.

Particularly, according to the present embodiment, only the purchasing screen for the goods to be purchased is stored as the shared data using the mobile phone 110, and is directly connected to the plurality of purchase screens using the PC 120 Thus, the user can pre-select an item in an environment in which it is difficult to purchase the item, and can immediately execute the purchase using the favorite category or the shopping cart category without the hassle of selecting again later.

In the above description, data selected / retrieved from one device is designated as shared data and displayed on another device. However, even when shared data received from two or more devices are comprehensively executed in another device, It will be an object. For the explanation, FIG. 16 will be referred to.

16 is a diagram for explaining a method for collectively providing shared data.

The server 200 stores data received from devices registered in the server 200 as shared data.

For example, when 'picture' data and 'name' data are stored in the PC 120, the server 200 stores 'picture' data and 'name' data stored in the PC 120, And stores it as shared data. When the 'phone number' data and the 'name' data are stored in the mobile phone 110, the server 200 receives and stores 'phone number' data and 'name' data stored in the mobile phone 420 And stores it as data.

The server 200 according to the present embodiment can collectively store data received from a plurality of devices. For example, as shown, 'name' data is added to 'picture' data received from PC 120, 'name' data is added to 'phone number' data received from mobile phone 110 Since the 'name' data are common, the common data are stored together.

Accordingly, when the device accesses the server 200, the server 200 transmits the integrated stored data to the device connected to the server 200. For example, as shown, when the TV 150 is connected to the server 200, the server 200 transmits 'address book' data, which is a combination of 'picture', 'telephone number' 150).

When receiving the 'address book' from the server 200, the TV 150 automatically executes an application for executing 'address book', and displays the received 'address book' on the screen.

In this manner, the server 200 stores / manages common data among the shared data, thereby allowing the user to access the server 200 from any device and utilize the common data.

It is assumed that data generated by one of the devices of the user is transmitted to the server 200 and designated as shared data. However, this is also only an example. Accordingly, data generated by another user may be stored in the server 200. [

For the explanation, FIG. 17 will be referred to. 17 is a diagram provided to explain a method of designating data generated by another user as shared data.

Operations of the mobile phone 110, the server 200, and the TV 150 are the same as those described above. Hereinafter, the blog server 210 will be described.

The blog server 210 stores contents such as video, audio, and text displayed on a blog. In addition, when a new content is displayed on the blog, the blog server 210 delivers a message to the mobile phone 110 indicating that the new content has been posted, and notifies the blog user of the fact that the new content has been posted.

Here, the blog user receiving the message includes not only the subject of ownership of the blog but also the subject of use of the blog. Thus, even if new content is displayed on a blog owned by a user, or when a new content is displayed on a blog owned by another user, the user can use the blog to display a new content on the blog of another user Quot; message &quot;.

The mobile phone 110 receives a message from the blog server 210 indicating that a new content has been posted on the blog. Upon receiving the message, the mobile phone 110 will be able to know the web page or internet address for calling the posted content.

In this case, the mobile phone 110 may designate a web page for calling contents posted on the blog as shared data and transmit the web page to the server 200. Accordingly, the server 200 designates and stores the web page as the shared data, and when the TV 150 connects to the server 200, the web page is transmitted to the TV 150.

For example, as shown in the figure, when another user places a new photo on a blog, the photo is stored in the blog server 210, and the blog server 210 sends a message to the blog that a new photo has been posted, (110) and informs the user.

After confirming the message received by the mobile phone 110, the user can immediately confirm the photograph displayed on the blog or designate it as the shared data, store it in the server 200, and check it later on the TV 110 .

Thus, data generated by another user can be designated as shared data in a specific device and executed via another device.
