[0073] The display unit 180 converts the video signal, data signal, OSD signal processed by the processor 170, and the video signal and data signal received from the external device interface unit 135 into R, G, and B signals, respectively, to generate a drive signal.

[0074] On the other hand, the display device 100 shown in Figure 1 is merely one embodiment of the present invention, so some of the components shown in the figure may be integrated, added, or omitted depending on the specifications of the display device 100 that will actually be implemented.

[0075] In other words, two or more components are integrated into one component as needed, or one component is subdivided into two or more components. Furthermore, the functions performed by each block are for illustrative purposes only to illustrate embodiments of the present invention, and their specific operations or devices do not limit the present invention.

[0076] Figure 2 illustrates a content server according to an embodiment of the present invention.

[0077] The content server 300 provides a recommendation service that recommends content preferred by viewers using the display device 100.

[0078] The content server 300 includes a communication interface 310, memory 320, and a processor 330.

[0079] The content server 300 transmits and receives data to and from at least one display device 100 via wired or wireless communication through the communication interface 310.

[0080] The memory 320 includes a content information database 321. The content information database 321 stores information about the content played on each device. For example, the content information database 321 stores content playback information, content setting information, or application installation information related to the identification information of each device.

[0081] When the processor 330 receives a content recommendation request from the display device 100 or an external device, it recommends content optimized for each device based on the data stored in the content information database 321.

[0082] Figure 3 illustrates a content provision system according to an embodiment of the present invention.

[0083] The content provision system 1000 includes at least one display device 100, at least one remote control device 200, and a content server 300.

[0084] The processor 170 of the display device 100 plays the content.

[0085] Furthermore, the processor 170 generates content playback information about the content being played. In addition, the processor 170 generates content setting information, which is information about the image quality, volume, and whether or not a preferred channel is set during content playback.

[0086] Content playback information includes at least one of the following: content identification information, content genre information, content playback start time information, content playback end time information, and total content playback time information.

[0087] Content settings information includes at least one of the image quality information, volume information, and preferred channel information regarding whether the user has registered the channel providing the content as their preferred channel, all of which are set for the content when the content is played.

[0088] The processor 170 transmits the device identification information of the display device 100, the generated content playback information, and the generated content setting information to the content server 300 via the communication interface. The device identification information is unique identification information used to distinguish it from other devices.

[0089] The content server 300 stores content playback information and content setting information received from the display device 100 in the content information database 321 in relation to the device identification information.

[0090] Meanwhile, the processor 170 receives content recommendation commands via the user input interface unit 150 or the voice acquisition unit 175.

[0091] When a content recommendation command is input, the processor 170 transmits the device identification information of the display device 100 and the content recommendation request to the content server 300 via the communication interface.

[0092] The communication interface 310 of the content server 300 receives device identification information and content recommendation requests from the display device 100.

[0093] The processor 330 of the content server 300 obtains content playback information and content setting information related to the display device 100 from the content information database 321 based on the device identification information.

[0094] The processor 330 generates content recommendation information and recommendation setting information for the display device 100 based on content playback information and content setting information. The content recommendation information includes recommended content identification information and recommended content genre information for at least one recommended content. The recommendation setting information also includes recommended image quality setting information and preferred channel information.

[0095] The processor 330 transmits content recommendation information and recommendation setting information to the display device 100 via the communication interface 310.

[0096] The processor 170 receives content recommendation information and recommendation setting information from the content server 300 via a communication interface.

[0097] The processor 170 displays at least one recommended content based on the received content recommendation information. Furthermore, when a playback command for recommended content is input via the user input interface unit 150 or the voice acquisition unit 175, the processor 170 sets the image quality of the recommended content to be played based on the received recommendation setting information and then plays it.

[0098] The system sets the video quality for recommended content and plays it. When the user requests a change to their preferred channel, it changes the channel to the preferred channel based on the user's preferred channel information.

[0099] On the other hand, the display device 100 mirrors the content being played to an external device. The external device includes other display devices or mobile devices. In this case, the mirrored content is viewed by the external device. Therefore, viewing information regarding the mirrored content needs to serve as basic data for recommending the content to the external device.

[0100] On the other hand, when the display device 100 performs a mirroring operation to an external device, it receives control commands from the external device to control the display device 100. These control commands include a content change command that changes the content being played from the first content to the second content. When the display device 100 receives a content change command, it plays the changed content. In this case, the display device 100 needs to send content playback information about the changed content to the content server 300 as information for the external device's content recommendation.

[0101] The following describes the operation process of a display device that interacts with a server in the content provision system according to the present invention. In this regard, Figure 4 is a flowchart of the process by which the display device logs into the content server based on a virtual account according to the present invention.

[0102] In this regard, an object of the present invention is to provide a display device that works in conjunction with a content server using a virtual account.

An object of the present invention is to generate a virtual account so that it is not necessary to provide information about the display device manufacturer's account. An object of the present invention is to support a function that allows users to purchase and play individual content using the display device manufacturer's account without having to separately register as a member on a server operated by a content provider.

[0103] Referring to Figures 1 to 4, a display device that interacts with a server in the content provision system according to the present invention will be described. In this regard, the content provision system according to the present invention is configured to include a display device 100, a remote control device 200, a content server 300, and a control server 400. The display device 100 is configured to include a wireless communication unit 173, a processor 170, and a display unit 180.

[0104] The processor 170 controls the display device 100 based on user commands or internal programs input via the user input interface unit 150. The processor 170 connects to a network to allow the user to download desired applications or application lists into the display device 100. The processor 170 is configured to execute at least one application program to control the display device 100. When the first application program 10 is executed, it determines whether the specific content can be purchased, played, refunded, or resold based on the viewing history and playback time of that content. When the second application program 20 is executed, it stores and manages information such as the playback history and playback time of the specific content.

[0105] The first application program 10 consists of an application program that is a software platform, but is not limited to this and may be modified as appropriate. The second application program 20 consists of webOS, which is the OS of the display device, but is not limited to this and may be modified as appropriate.

[0106] The display unit 180 is configured to display a screen requesting the user to log in with a specific account in order to view content. In this regard, Figures 5a and 5b show the top screen and login screen of the display device provided by a control server managed by the manufacturer of the display device. On the other hand, Figures 6a and 6b show the top screen and a screen displaying the profiles of multiple users when logging in with the login account of a specific user in the home.

[0107] As shown in Figures 1, 4, and 5a, the top screen of the display unit 180 of the display device 100 displays information regarding the terms of use and icons 181, as well as icons corresponding to services provided by multiple content servers. When input is received from the remote control device 200 to select an icon 181, a login screen regarding login options is displayed.

[0108] As shown in Figures 1, 3, 4, and 5b, multiple icons 182a, 182b, and 182c related to login options are displayed on the display unit 180. When input for icon 182a is received from the remote control device 200, the application program of the mobile terminal 500 is configured to log in with a specific account. When input for icon 182b is received from the remote control device 200, the system is configured to log in with a specific account in the mobile web environment. When input for icon 182c is received from the remote control device 200, the display device 100 is configured to log in with a specific account.

[0109] As shown in Figures 1, 3, 4, and 6a, an icon 183a associated with the first user's first login account is displayed on one side of the display unit 180. An icon 183b for executing a second application program such as webOS is displayed on the other side of the display unit 180. Icons corresponding to services provided by multiple content servers are displayed on the display unit 180, categorized by type. Icons corresponding to services provided by multiple content servers are displayed, categorized by type such as home office, games, music, home hub, and sports.

[0110] As shown in Figures 1, 3, 4, 6a, and 6b, icons 184a, 184b, 184c, and 184d associated with multiple profiles of multiple users are displayed on a specific area of ​​the screen on the display unit 180. By selecting an icon 183a associated with the first login account, icons 184a, 184b, 184c, and 184d of multiple login accounts of family members are displayed on the screen. The icon 184a associated with the first login account of the first user corresponding to DAD is displayed on the screen. For example, the first user's first login account is aaa@gmail.com. An icon 185a for logging out the first login account of the first user who is currently logged in is displayed in the lower area of ​​the icon 184a associated with the first user's profile.

[0111] Meanwhile, icon 184b, associated with the second login account of the second user corresponding to CHLOE, is displayed on the screen. For example, the second login account of the second user is bbb@gmail.com. Icon 184c, associated with the third login account of the third user corresponding to MOM, is displayed on the screen. Additionally, icon 184d, for generating the fourth login account of another fourth user, is displayed on the screen.

[0112] The following describes a display device that interacts with a server in a content provision system according to the present invention, with reference to Figures 1 to 6b. The display device 100 is configured to include a user input interface unit 150, a processor 170, and a display unit 180.

[0113] The user input interface unit 150 is configured to receive a login request for a specific account for content viewing from the remote control device 200 (S10). The processor 170 is configured to acquire screen information for content viewing based on the login request for the specific account. In connection with this, login requests for the first to third login accounts of the first to third users shown in Figure 6b are received via the user input interface unit 150.

[0114] The display unit 180 is configured to display a screen for login requests, as shown in Figure 5b or Figure 6b. The display unit 180 is configured to display a specific screen according to the screen information obtained for each login account when logging in with a specific account. In this regard, when logging in with the first login account of the first user corresponding to DAD in Figure 6b, the screen in Figure 6a is displayed on the display unit 180.

[0115] The following describes in detail the login procedure performed by the processor 170 and the process of generating or verifying a virtual account in conjunction with the control server 400 to play content. The processor 170 transmits login information to the second application program 20, which is linked with the control server 400 (S20). The second application program 20 uses the login information to transmit a login request to the control server 400 using the login account of a specific user (S30). Thus, a login attempt is made using the login account of a specific user.

[0116] The processor 170 controls the second application program 20 so that it attempts to log in to a specific account in conjunction with the control server 40 based on the login information. The processor 170, in conjunction with the control server 40, determines whether or not it has been the first time to attempt to log in using the login information (S110).

[0117] If the processor 170 determines that it has made its first login attempt using the login information of a specific account, it receives a coordinated response from the content server 300 in conjunction with the control server 40 indicating that it has logged in with the generated virtual account (S160). In connection with this, a server-to-server coordination request using the virtual account (S140) is transmitted from the control server 400 to the content server 300 (S140). The control server 400 receives a response from the content server 300 indicating that the coordination (login) was successful (S150).

[0118] The processor 170 receives a login success response via the content server 300 and the control server 400, indicating that the connection with the specific content server 300 has been successfully established by logging in with the generated virtual account. Upon receiving the login success response, the processor 170 displays a login success message on the screen of the display unit 180.

[0119] On the other hand, the present invention allows connection to the content server 300 via the control server 400 without generating a separate virtual account by confirming a previous virtual account based on the history of previous logins with a specific account. In this regard, if it is determined that a login attempt has been made previously with the login information of a specific account, the processor 170, in conjunction with the control server 400, confirms the virtual account corresponding to the previous login information (S130). In this regard, the processor 170, in conjunction with the control server 400, obtains the virtual account corresponding to the previous login information from the control server 400. The processor 170, in conjunction with the control server 400, receives a confirmation response that the connection with the specific content server 300 using the obtained virtual account has been successfully completed (S150).

[0120] On the other hand, the display device according to the present invention can generate virtual accounts for multiple content providers (CPs). In this regard, Figure 7 is a flowchart of an embodiment according to the present invention that generates multiple accounts corresponding to virtual accounts in conjunction with multiple content servers.

[0121] As shown in Figures 1 to 7, the processor 170 generates a first account corresponding to a virtual account on the display unit 180 in conjunction with the first content server 300 in response to a first execution input for a first icon. For example, the first content server 300 is a content server that provides Apple TV services. Therefore, the first account generated corresponding to the virtual account aaa@lge.com will be aaa@lge.apple.com, but is not limited to this.

[0122] In connection with this, the processor 170 receives a first execution input for the first icon from the remote control device 200 (S301). The processor 170, in conjunction with the control server 400, transmits a first account generation request to the first content server 300 to generate a first account corresponding to the virtual account (S310, S320). The processor 170, in conjunction with the control server 400, receives a first account generation response from the first content server 300 indicating that the first account has been generated (S330, S340).

[0123] Furthermore, the processor 170, in response to a second execution input for a second icon on the display unit 180, works in conjunction with the second content server 300b to generate a second account corresponding to the virtual account. For example, the second content server is a content server that provides the Netflix service. Therefore, the second account generated in response to the virtual account aaa@lge.com will be aaa@lge.netflix.com, but is not limited to this.

[0124] In connection with this, the processor 170 receives a second execution input for the second icon from the remote control device 200 (S301b). The processor 170, in conjunction with the control server 400, transmits a second account generation request to the second content server 300b to generate a second account corresponding to the virtual account (S310b, S320b). The processor 170, in conjunction with the control server 400, receives a second account generation response from the second content server 300b indicating that the second account has been generated (S330b, S340b).

[0125] On the other hand, in the content provision system according to the present invention, a user who has applied for a service account using a virtual account can apply for a separate service account. In connection with this, if a user who has applied for a service account using a virtual account applies for a separate service account via a web page or application related to the content server, a service account will be generated. A mobile terminal 500 transmits a request for generation of a first service account and / or a request for generation of a second service account to the control server 400 (S311, S312). The first service account generated for the first user's first content server 300 will be aaa@apple.com. The second service account generated for the first user's second content server 300b will be aaa@netflix.com.

[0126] The processor 170 receives a first notification via the control server 400 indicating that a first service account has been created, or a second notification indicating that a second service account has been created (S350). In connection with this, the first service account is created by the first application program corresponding to the first content server 300. Also, the second service account is created by the second application program corresponding to the second content server 300b. Note that the first service account and the second service account are accounts of the same person as the virtual account. For example, the first service account aaa@apple.com and the second service account aaa@netflix.com are accounts of the same person as the virtual account aaa@lge.com. Both the first service account and the second service account are accounts of the first user, for example, DAD.

[0127] On the other hand, the display device according to the present invention can perform account integration by communicating a request to the user to integrate a separate service account into a virtual account. Account integration using a virtual account activates content management and distribution by the display device manufacturer. Furthermore, by integrating accounts using a virtual account, the user can view content provided by multiple content providers with a single virtual account without having to create separate accounts.

[0128] The processor 170 transmits a first request to the mobile terminal 500 via the control server 400, requesting that the first service account or the second service account be integrated into a virtual account (S360). In connection with this, the first user has requested the creation of the first service account by the mobile terminal 500. When the processor 170 integrates the first service account or the second service account into a virtual account, it transmits a message to the mobile terminal 500 that the virtual account can be used to manage multiple services in an integrated manner.

[0129] The processor 170 receives a first response from the mobile terminal 500 accepting the first request (S370). Upon receiving the first response, the processor 170 controls the control server 400 to integrate the first or second service account into a virtual account. Thus, the integration into the virtual account can be displayed on the screen of the mobile terminal 500.

[0130] On the other hand, the content delivery system according to the present invention can be integrated into a virtual account via a screen displayed on a display device. Furthermore, the content delivery system according to the present invention can recommend subscriptions based on the user's frequency of use and usage time. In this regard, Figure 8 is a flowchart of the method used by the content delivery system according to the present invention for virtual account integration and subscription recommendation.

[0131] As shown in Figures 1 to 8, if the processor 170 determines that it has first attempted to log in using the login information of a specific account, it creates a virtual account (S120). The processor 170 determines whether there is a first service account or a second service account of the same person as the created virtual account (S410). If the processor 170 determines that it has previously attempted to log in using the login information of a specific account, it retrieves the virtual account (S130). The processor 170 determines whether there is a first service account or a second service account of the same person as the retrieved virtual account (S410).

[0132] If there is no first or second service account for the same person as the virtual account, the virtual account performs the steps from step S420 onward related to the operation of recommending subscriptions based on the user's usage frequency and usage time. If there is a first or second service account for the same person as the virtual account, the processor 170 displays a second request on the display unit 180 requesting that the first or second service account be integrated into the virtual account. When the first or second service account is integrated into the virtual account, the processor 170 displays a message on the display unit 180 indicating that the virtual account can perform integrated management of multiple services. The processor 170 transmits the second request regarding the integrated management of multiple services by the virtual account (S411) and displays a message on the display unit 180 indicating that integrated management is possible.

[0133] The processor 170 receives a second response from the remote control device 200, which is wirelessly connected to the display device 100, acknowledging the acceptance of a second request to integrate into a virtual account (S412). Upon receiving the second response to integrate into a virtual account, the processor 170 controls the control server 400 to integrate either the first or second service account into a virtual account. To this end, the processor 170 transmits an integration request to the control server 400 requesting that either the first or second service account be integrated into a virtual account (S413).

[0134] The content provision system according to the present invention can recommend subscriptions based on the user's usage frequency and usage time. In this regard, the processor 170 determines whether the first usage time of the first service from the first content server 300 by the first account has exceeded the first threshold time. The processor 170 also determines whether the second usage time of the second service by the second account has exceeded the second threshold time. Therefore, the processor 170 determines whether the first usage time has exceeded the first threshold time and the second usage time has exceeded the second threshold time (S420).

[0135] When the usage times of the first and second services exceed the first and second threshold times, the processor 170 transmits information regarding the usage times of the first and second services to the control server 400 (S421). The processor 170, in conjunction with the control server 400, displays a subscription request message for the integrated subscription service of the first and second services on the display unit 180. To this end, the processor 170 receives a subscription request message for the integrated subscription service of the first and second services from the control server 400 (S422).

[0136] On the other hand, in the content playback system according to the present invention, family members and virtual accounts can be integrated and separated. In this regard, Figure 9 is a flowchart of the method used in the content provision system for managing virtual accounts among family members according to the present invention. As shown in Figure 6b, the processor 170 generates login accounts for multiple users.

[0137] As shown in Figures 1 to 9, the processor determines whether the relationship between the first user and the second user is set as family among multiple users (S510). If the relationship between the first user and the second user is not set as family, the processor 170 transmits a first mapping request to the control server 400 requesting that the first and second login accounts of the first and second users be mapped to separate first and second virtual accounts (S511).

[0138] If the relationship between the first user and the second user is set to family, the processor 170 controls the control server 400 to map the first user's first login account and the second user's second login account to the same virtual account. The processor 170 transmits a second mapping request to the control server 400 requesting that the first user's first login account and the second user's second login account be mapped to the same virtual account (S512).

[0139] The processor 170 determines whether the first login account is logged out and the user is logged in with the second login account (S520). The first login account is set as the representative account for login accounts. If the first login account is logged out and the user is logged in with the second login account, the processor 170 controls the control server 400 to map the second login account to the second virtual account. When the first and second login accounts are mapped to the same virtual account, if the second login account logs out and then logs in again with the second login account, the second login account is separated from the same virtual account. Therefore, when the first login account logs out, the second login account is separated from the same virtual account and mapped separately to the second virtual account.

[0140] The processor 170 transmits a first mapping request to the control server 400 requesting that the first and second login accounts of the first and second users be mapped to separate first and second virtual accounts (S521). If the first login account is not logged out, the processor 170 transmits a second mapping request to the control server 400 requesting that the first and second login accounts be mapped to the same virtual account (S522).

[0141] On the other hand, in the content provision system according to the present invention, if the first user is logged out, other users are assumed to intend to connect using different virtual accounts rather than the same common virtual account. When the first login account logs out while mapped to the same virtual account, the processor 170 determines whether or not the second login account has logged in for the first time (S530).

[0142] When the system is mapped to the same virtual account, if it determines that the user has logged in with the second login account that was previously used, the processor 170 obtains the virtual account from the control server 400 (S531). When the system is mapped to the same virtual account, if it determines that the first login account has logged out and the user has logged in for the first time with the second login account, the processor 170 requests the control server 400 to create the second virtual account (S532). The processor 170, in conjunction with the control server 400, receives a response indicating that the system has successfully linked with the specific content server by logging in with the created second virtual account (S540).

[0143] On the other hand, the content delivery system according to the present invention may be configured to request integrated subscriptions among family members. In this regard, Figure 10 is a flowchart of how to request integrated subscriptions among family members in the content delivery system according to the present invention. The method for requesting integrated subscriptions among family members will be described with reference to Figures 1 to 10.

[0144] The processor 170 interacts with the first content server 300 and the second content server 300b using a virtual account. The processor 170 receives the first content from the first content server 300 using a virtual account (S611). The processor 170 receives the second content from the second content server 300b using a virtual account (S613).

[0145] The processor 170 determines whether the sum of the first usage time of the first service provided by the first user's first login account and the second user's second login account from the first content server 300 exceeds the first threshold time (S620). The processor 170 also determines whether the sum of the second usage time of the second service by the first login account and the second login account exceeds the second threshold time (S630). In this regard, if the first and second login accounts are managed together under the same virtual account, the total usage time of a specific service is calculated by the virtual account.

[0146] When the total first usage time exceeds the first threshold time, the processor 170 transmits an integrated subscription request message regarding the first service for the first user and the second user to the control server 400 (S621). In connection with this, the processor 170 determines whether the total first usage time exceeds the first threshold time and whether the total second usage time exceeds the second threshold time (S640).

[0147] If the total usage time for the first service exceeds the first threshold time, and the total usage time for the second service does not exceed the second threshold time, the processor 170 transmits an integrated subscription request message for the first service to the control server 400 (S621). Thus, by using a subscription that takes into account the combined usage of the first service on the first channel by the first and second users, the first service on the first channel can be used at a lower cost than individual viewing.

[0148] If the total usage time for the second channel exceeds the second threshold time, the processor 170 transmits an integrated subscription request message for the second service for both the first and second users to the control server 400 (S631). If the total usage time for the first channel does not exceed the first threshold time, and the total usage time for the second channel exceeds the second threshold time, the processor 170 transmits an integrated subscription request message for the second service to the control server 400 (S631). Therefore, by using a subscription that takes into account the combined usage of the second service on the second channel for both the first and second users, the second service on the second channel can be used at a lower cost than individual viewing.

[0149] As mentioned above, the processor 170 determines whether the total usage time for the first period exceeds the first threshold time and whether the total usage time for the second period exceeds the second threshold time (S640). If the total usage time for the first period exceeds the first threshold time and the total usage time for the second period exceeds the second threshold time, the processor 170 transmits an integrated subscription request message to the control server 400 (S641). Therefore, an integrated subscription that takes into account the total usage of services across multiple channels for multiple users allows users to utilize multiple services on multiple channels at a lower cost than channel-specific subscriptions.

[0150] If the total of the first usage time does not exceed the first threshold time, and the total of the second usage time does not exceed the second threshold time, the processor 170 repeats the process of determining whether the total of the first usage time of the first service exceeds the first threshold time (S620).

[0151] On the other hand, the content provision system according to the present invention can save content viewing history in different ways based on the viewing time of specific content and play back content. As shown in Figures 1 to 4, the processor 170 displays on the display unit 180 that it has logged in with specific login information based on a login success message received from the control server 400 (S160). The processor 170 receives and saves the cumulative playback time and the current playback time of the first content from the content server 300 (S230). The processor 170 receives the first content from the content server 300 at a point in time after the current playback time via the control server 400 and displays it on the display unit 180 (S260).

[0152] On the other hand, the content provision system according to the present invention can control content playback in a different manner by determining the automatic logout time and whether or not the user is logged in on another device in response to a pause request. In this regard, Figure 11 is a flowchart of a method for controlling content playback by determining the automatic logout time and whether or not the user is logged in on another device in response to a pause request.

[0153] As shown in Figures 1 to 11, the processor 170 receives a pause request from the remote control device 200 (S11). Based on the pause request, the processor 170 receives and stores the cumulative playback time and the current playback time of the first content on the content server 300 (S30). The processor 170 transmits a request to stop streaming the first content at a point after the current playback time to the content server 300 via the control server 400 (S41, S42). As a result, streaming transmission from the content server 300 to the display device 100 is stopped (S51). The processor 170 controls the display unit 180 so that playback of the first content is interrupted (S60).

[0154] On the other hand, if playback of the first content is interrupted, it is determined whether the automatic logout time for the first user's first login account has been exceeded (S610). If playback of the first content is interrupted and the automatic logout time for the first login account has not been exceeded, the processor 170 saves the cumulative playback time, the current playback time, and the last connection time of the first content. By comparing the cumulative playback time with a threshold time related to previews, a purchase request and purchase of the first content may be made. Alternatively, by comparing the cumulative playback time with a threshold playback time related to refunds after content purchase, it may be determined whether a refund for the first content is possible.

[0155] The processor 170 may store the current time instead of the last connection time of the first content. The last connection time is set to the time when the first content was played by multiple devices and other login accounts. The processor 170 determines whether the first user's first login account and the second user's second login account have logged in on other devices (S630).

[0156] If the first and second login accounts are logged in on other devices, the processor 170 controls the display device 100 to log out. The processor 170 transmits the logout request for the first and second login accounts on the display device 100 to the control server (S640). In response to the logout request, the processor 170 receives a logout success response from the control server 400. When the first login account logs out on the display device 100, the management of the cumulative playback time is performed on other devices that are logged in, such as mobile terminals. Therefore, the processor 170 saves the current playback time (or last connection time) of the first content (S660).

[0157] On the other hand, the content provision system according to the present invention can control content playback in different ways by determining whether the user is logged out or logged in on another device in response to a request to unpause the playback. In this regard, Figure 12 is a flowchart of a method for controlling content playback by determining whether the user is logged out or logged in on another device in response to a request to unpause the playback.

[0158] As shown in Figures 1 to 12, the processor 170 receives a request to release the pause from the remote control device 200 (S12). Based on the request to release the pause, the processor 170 determines whether the display device is logged out or not (S710). If the display device is logged out, it determines whether the user is logged in on other devices (S720).

[0159] Based on the request to release the suspension, the processor 170 transmits the login information to the control server 400 if the first user's first login account is logged in (S730). In connection with this, if the display device is logged in and not logged out, it transmits the login information to the control server 400 (S730).

[0160] On the other hand, if the first login account is logged out and logged in on another device, the control server 400 is controlled to request that the first login account be logged out on the other device (S740).

[0161] The processor 170, in conjunction with the control server 400, verifies the virtual account (S130). By logging in with the verified virtual account, the processor 170, in conjunction with the control server 400, receives a response indicating that the interaction with the content server 300 was successful. Based on the login success message received from the control server 400, the processor 170 displays on the display unit 180 that the user has logged in with specific login information (S160). The processor 170 receives and saves the cumulative playback time and the current playback time of the first content from the content server 300 (S230). The processor 170 receives the first content from the content server 300 at a point in time after the current playback time via the control server 400 and displays it on the display unit 180 (S260).

[0162] Meanwhile, the processor 170 determines whether the first content has been played on another device (S231). If the first content has not been played on another device, the processor 170 requests playback of the first content based on the current playback time of the first content saved in a paused state (S240a), and plays the first content (S260). If the first content has been played on another device, the processor 170 requests playback of the first content based on the last connection time of the first content saved in a paused state (S240b), and plays the first content (S260).

[0163] On the other hand, when content is unpaused, playback may be performed considering whether or not a family member played the content. In this regard, Figure 13 is a flowchart of a method for controlling content playback by determining whether or not the content was played using another login account in response to an unpause request.

[0164] As shown in Figures 1 to 13, the processor 170 determines whether the first content has been played by the second user, who is related to the first user of the first login account (S810). If the first content has not been played by the second login account, the processor 170 requests playback of the first content based on the current playback point of the first content saved in a paused state (S240a) and plays the first content (S260).

[0165] If the first content is played using the second login account, the processor 170 requests a response from the second login account regarding whether or not to play the first content based on the last connection time of the first content saved when the second login account logged in. The processor 170 displays a dialog box on the display unit 180 regarding whether or not to play the first content based on the last connection time of the first content (S811).

[0166] The processor 170 determines whether it has received a response to play the first content based on the last connection time of the first content (S820). If it receives a response to play the first content based on the last connection time, it requests playback of the first content based on the last connection time of the first content (S240b). Therefore, playback of the first content is performed from a point in time after the last connection time (S260).

[0167] When the dialog box receives a request to play the first content based on the current playback time, the processor 170 requests playback of the first content based on the current playback time (S240b). Also, if no response is received to play the first content based on the last connection time, the processor 170 requests playback of the first content based on the current playback time (S240b).
