[0088] FIG. 2 is a flowchart illustrating a method for displaying content of a video display device according to one embodiment, FIG. 3 is an exemplary illustration of a user interface in which an external electronic device transmits content to a video display device, and FIG. 4 is an exemplary illustration of a screen providing information about content received from an external electronic device to a user on a display screen of a video display device according to one embodiment.

[0089] Referring to FIGS. 2 to 4, a content display method of an image display device (100) according to one embodiment of the present specification may include an operation (S210) in which the image display device provides a power state to an external server, an operation (S220) in which content transmitted by an external server (190) is received at a time determined based on the power state and a scheduled transmission time, and an operation (S230) in which the received content is displayed on a display.

[0090] In operation S210, the video display device (100) can transmit a power status to an external server (190). The power status transmitted by the video display device (100) may be an off state and an on state, but additionally, the power status may include a completely off state.

[0091] The off state is a state in which the display (111) of the video display device (100) is turned off, and the viewer of the video display device (100) may determine that the video display device (100) is turned off. However, in the off state, some modules of the communication unit (130) and the processor (110) of the video display device (100) operate in a low-power standby mode to perform minimal data exchange with an external server (190). In the off state, the video display device (100) can periodically transmit the power status of the video display device (100) to the external server (190).

[0092] The ON state may be a state in which the display (111) of the video display device (100) is turned on, and the communication unit (130) and the processor (110) are also operating normally. In the ON state, a viewer of the video display device (100) may be watching specific content.

[0093] The image display device (100) may be in a completely off state if power is not fully supplied. In the completely off state, the processor (110) and the communication unit (130) of the image display device (100) may not operate. When the image display device (100) is in a completely off state, the external server (190) may not receive the power status of the image display device (100) for a certain period of time or longer. Then, the external server (190) may determine that the image display device (100) is in a completely off state. When the external server (190) receives the power status again from the image display device (100), it can identify the power status of the image display device (100) according to the received information.

[0094] According to one embodiment, in operation S210, the communication unit (130) establishes a network connection with an external server (190) and, under the control of the processor (110), can transmit the power status of the image display device (100) to the external server (190).

[0095] The external electronic device (199) can request content transmission by registering the type of selected content (e.g., photos, videos, documents, and links), transmission policy (immediate transmission, scheduled transmission, and transmission when power is turned on), and / or user account information with the external server (190) at any time regardless of the operation of FIG. 2. The external electronic device (199) can upload the entire original content or register content location information and visualized representative information instead of the original with the external server (190), and the external server (190) can prepare data to be transmitted to the video display device (100) based on the registered information.

[0096] In operation S220, the video display device (100) can receive content transmitted by an external server (190). According to one embodiment, the external server (190) can transmit content to the video display device (100) at a time determined based on the power status of the video display device (100) and the scheduled time of transmission of the content.

[0097] The communication unit (130) of the video display device (100) can receive content via a streaming or download method while verifying the integrity of the data through a secure channel, and in some embodiments, only visualized representative information can be received first before the entire data arrives. Additionally, the communication unit (130) can perform error detection, retransmission requests, and decryption procedures during the data transmission process, and the received data can be temporarily stored in memory (150).

[0098] The external server (190) can determine the timing of content transmission by referring to the received power status information. For example, if it is confirmed that the video display device (100) is in an off state, the content can be scheduled to be transmitted at a scheduled time according to the content transmission policy set for the content, or at the time when the video display device (100) is changed to an on state.

[0099] If the video display device (100) is off at the scheduled time, the video display device (100) may turn on by itself at the time when receiving content begins, or it may turn on in advance according to the scheduled transmission time received from the external server (190). In operation S220, the processor (110) determines the power status of the video display device (100), and if it determines that the video display device (100) is off, it may turn on the power at the time when receiving content begins to change the video display device (100) to an on state.

[0100] According to one embodiment, if the video display device (100) receives and stores transmission reservation information for content from an external server (190), the video display device (100) may change the video display device (100) to an ON state in advance in accordance with the time of receiving the content reservation according to the transmission reservation.

[0101] According to one embodiment, in operation S230, the processor (110) may display the received content on the display (111). As shown in FIG. 4, the received content may be in various forms such as photos, videos, documents, and / or links, and along with the content, user identification information of the uploader of the content may be displayed. If there are multiple pieces of content, the processor (110) may classify them by type or topic and display them on the display (111) in the form of tabs, lists, or thumbnails. According to one embodiment, the information may be data received by the video display device (100) by requesting it from an external server (190). When a viewer selects specific content among the multiple pieces of content displayed on the display (111), the content may be downloaded to memory (150) and played in its entirety. For content that is not selected, only visualized representative information may be maintained, and control may be exercised to re-receive the original data from the external server (190) or an external electronic device (199) if necessary. Additionally, the display (111) may display user interface elements such as a play button, view later, and / or delete, so that the user can intuitively browse, play, and manage the shared content.

[0102] After operation S220 or after operation S230, the following operations may be added. The processor (110) may periodically receive the status of content in a shared space managed by an external server (190) and display it on a display (111). At this time, the shared space may be a chat room, group chat room, or a dedicated area for content sharing on an SNS platform, and the type of shared content, sharer identification information, and / or upload time may be displayed together. The user can check the sharing history and select specific content to view or download.

[0103] An external server (190) can manage the status of shared content in a chat room or group conversation space of a mobile terminal (external electronic device (199)) by linking with an SNS platform. For example, when a user shares a photo or video in a mobile messenger chat room, the content is recorded in the external server (190), and the video display device (100) can periodically synchronize this and display it on the display (111). In this process, the sender of the content, the upload time, and chat room identification information may be provided together, and the user can intuitively view the sharing history of the mobile chat room through the video display device (100). Furthermore, the processor (110) can control functions such as filtering by chat room, sorting by user, and highlighting recently shared content so that the user can easily browse the content shared in the SNS chat room. By synchronizing and managing the sharing status in the messenger chat space, the user can easily view the content shared on the mobile device on the TV screen as well.

[0104] When a user selects a specific account on a video display device (100), the processor (110) can transmit content to an external electronic device (199) linked to that account. In this process, the communication unit (130) transmits a request for content transmission through an external server (190), and the external server (190) verifies the target account information and routes the content to the corresponding external electronic device (199). The external electronic device (199) can display the received content through a user interface and can save or reshare it as needed.

[0105] The content display method according to the above-described embodiment automatically controls the display of content according to the power status and transmission time, thereby allowing the user to smoothly view the content without power operation.

[0106] Referring to FIG. 3, an external electronic device (199) can enable a user to select content to share through a messenger screen. For example, the user can select a content sharing button within a menu window (300) that includes a plurality of buttons (310) displayed on the display of the external electronic device (199). Then, a content sharing request screen may be displayed on the screen. The content sharing request screen may be equipped with content sharing selection buttons (320). The content sharing selection buttons (320) may include a smartphone content button and an SNS video button. When the user selects the smartphone content button, the external electronic device (199) can sequentially select content to share and upload the selected content by pressing the upload button (330). When the user selects the SNS video button, the external electronic device (199) can provide content location information and representative information of the corresponding video to an external server (190).

[0107] Referring to FIG. 4, the video display device (100) can provide content received from an external server (190) to the user in the form of a popup via the display (111). While the previously displayed content or video continues to be displayed on the entire display (111), a popup screen (400) indicating that new content has been received can be displayed over the existing video. The popup screen (400) may display visualized representative information (410) of the content (e.g., thumbnail), sender, and related information (420), and options for viewing photos, viewing videos, and / or viewing later may be provided through the user interface (430). If the user selects a specific option within a pre-specified time, the content is downloaded from the server (190), stored in memory (150), and can be played on the entire display (111). If the user does not select a specific option within a pre-specified time, the video display device (100) can store content-related information (410, 420) in memory (150) and remove the corresponding pop-up screen (400).

[0108] According to one embodiment, the processor (110) may generate or receive visualized representative information to provide identifiable information to the user without downloading the entire received content. The visualized representative information (410) may be implemented, for example, as a thumbnail image in the case of photo data, a preview frame or a representative scene still image in the case of video, a cover image or summary page in the case of document, or a site icon (favicon) or a preview capture screen in the case of link information. This visualized representative information may be stored as low-capacity data in memory (150) and provided so that even content not selected by the user can be intuitively viewed on a list screen. By downloading and playing the entire data only for the selected content, efficient utilization of storage resources and reduction of network load can be achieved.

[0109] The image display device (100) according to the above-described embodiment intuitively displays user information along with received content and can manage all content or representative information according to user selection.

[0110] In the embodiments according to FIGS. 2 to 4, the embodiments organically link the transmission of content through an external electronic device (199), the transmission management of an external server (190), and the display of content through a video display device (100), thereby enabling the user to easily share and explore various content.

[0111] FIG. 5 is a flowchart illustrating the process of transmitting reserved content from an external server according to one embodiment.

[0112] Referring to FIG. 5, the method for managing content transmission schedule information may include an operation (S510) of generating content transmission schedule information at a server (190) and an operation (S520) of receiving, storing, and managing the transmission schedule information at a video display device (100).

[0113] In operation S510, the server (190) receives a content transmission request provided by an external electronic device (199) and can generate content transmission schedule information based on the request. The external electronic device (199) can provide content or content location information to the server (190) along with a transmission policy specified by the user (immediate transmission, scheduled transmission, transmission when power is turned on).

[0114] Based on this information, the server (190) can generate metadata for the scheduled time of transmission, content location information (e.g., file path, URL), user account information, and / or device identifier, and configure this as content transmission schedule information. The external server (190) can include the size and type of content (photo, video, or document), and / or visualized representative information (thumbnail, or preview data) in the content transmission schedule information.

[0115] In operation S520, the external server (190) can store and manage the generated transmission schedule information. Additionally, the external server (190) can transmit the content to the video display device (100) at the scheduled transmission time based on the stored content transmission schedule information.

[0116] Additionally, the external server (190) can transmit content transmission schedule information to the video display device (100). According to one embodiment, since the external server (190) can store and manage content transmission schedule information for a plurality of video display devices (100) and a plurality of external electronic devices (199), it can extract only the content transmission schedule information for the corresponding video display device (100) and transmit it to the corresponding video display device (100).

[0117] The communication unit (130) of the video display device (100) can receive information regarding the scheduled transmission of content from the server (190). The processor (110) stores and manages the received information regarding the scheduled transmission of content in memory (150) and can control the timing of the reception of content based on this information. For example, if the scheduled transmission time is set to a specific time, the processor (110) can change the video display device (100) to an ON state when the time arrives, if the video display device (100) is in an OFF state, receive content from the external server (190), and display the content on the display (111).

[0118] According to one embodiment, if the received content transmission schedule information includes a device identifier, the processor (110) determines whether the device identifier is the same as the device identifier of the video display device being controlled, and only if they are the same, the processor (110) may store and manage the content transmission schedule information. The processor (110) may manage a plurality of transmission schedule information simultaneously and control the display order by determining priority by user and / or by content type.

[0119] The external server (190) and / or video display device (100) according to the above-described embodiment manages content transmission and display based on transmission schedule information, so that content can be automatically displayed at a scheduled time without user intervention.

[0120] FIG. 6 is an example of a screen displaying content transmitted from multiple users according to one embodiment on a video display device.

[0121] Referring to FIG. 6, content shared by multiple users can be displayed on the display (111) of the video display device (100), separated by account. The first account (611) is an account corresponding to user AA, and a list of photo and video content (610) transmitted by the user is included and displayed. The second account (612) is an account corresponding to user BB, and multiple photo and video content transmitted by the user is displayed separated under account groups.

[0122] The processor (110) receives content transmitted by multiple users from an external server (190) and analyzes user identification information or account information provided with each piece of content to control the display to separate and display content by user. Classification tabs by content type (photos, videos, and / or links) may be displayed at the top of the screen, and content groups by user account may be hierarchically listed in the screen area.

[0123] According to one embodiment, the separation of content groups by user account shown in FIG. 6 is performed on an external server (190), and the video display device (100) requests the information from the external server (190), receives the information from the external server (190), and displays it on the display (111).

[0124] The user can select a specific account on the screen of Fig. 6 displayed on the display to view only the content of that account, or view the content of all accounts as an integrated list.

[0125] The processor (110) assigns an identifier, icon, or name label to content per user account so that it can be intuitively distinguished, and may provide different sorting methods depending on the transmission time, size, and / or type of the content. In some embodiments, users may download content per account or extend the storage period, and may receive separate notifications for content shared from a specific account.

[0126] The image display device (100) according to the above-described embodiment can efficiently manage content even in an environment shared by multiple users by separating and displaying content by multiple user accounts.

[0127] FIG. 7 is an example screen diagram illustrating content classification and classification menu display operations according to one embodiment.

[0128] Referring to FIG. 7, the display (111) of the video display device (100) may display received content classified by type and date. At the top of the screen, tabs for classifying content by type (photos and videos, photos, videos, and / or YouTube) are displayed so that the user can select the desired category. For example, if the user selects the "Photos" tab, only photo data is displayed, and if the user selects the "Videos" tab, only video data is filtered and displayed.

[0129] Content received on a specific date (701) (e.g., October 14) can be displayed on the screen grouped into visualized representative information such as photo thumbnails and video thumbnails. Content received on another date (702) (e.g., July 19) is displayed in a separate group, allowing the user to intuitively browse content by date or type.

[0130] The processor (110) can automatically classify content received through the communication unit (130) according to type (photo, video, document, and / or link) or content (e.g., specific keyword, topic), and can provide the corresponding classification menu through the display (111). If there is no content of a specific type, the corresponding classification tab may not be displayed on the screen or may be provided in a disabled state.

[0131] In some embodiments, the user can simultaneously select multiple contents on the classification screen, and the selected contents may be distinguished by visual objects such as a check mark (720). The content selected by the user may be downloaded and stored in memory (150), while the unselected content may retain only visualized representative information. This allows for efficient utilization of storage resources, and at the same time, the user can intuitively select and save only the desired content.

[0132] The image display device (100) according to the above-described embodiment classifies and displays content by type and date, thereby allowing the user to quickly and intuitively search for the content they want.

[0133] FIG. 8 is an example of a screen when there is no shared content according to one embodiment.

[0134] Referring to FIG. 8, content can be classified and displayed on the display (111) of the video display device (100) according to specific types. A content classification tab (photos and videos, photos, videos, or YouTube) is provided at the top of the screen, and the user can select the desired classification item.

[0135] For example, FIG. 8 illustrates a screen in which a specific category tab is selected but there is no content corresponding to the selected category. At this time, a message (810) stating "There is no shared content" is displayed on the display, and a guide message may be provided to allow the user to share the content through another device.

[0136] The processor (110) can automatically classify content received through the communication unit (130) by type and control it to display a guidance message in an area corresponding to the classification tab if content of a specific type does not exist. The guidance message can serve to induce the user to share content through a connected smartphone or external electronic device (199), which can help the user understand intuitively and contribute to activating the content sharing function.

[0137] FIG. 9 is an example diagram illustrating storage period management and expiration notification according to one embodiment.

[0138] Referring to FIG. 9, a notification message (910) may be provided to the user on the display of the image display device (100) before the storage period expires. The notification message (910) may be displayed in a form such as, for example, "The storage period is about to expire. Would you like to extend the storage period?" and the user may extend the storage period by selecting a confirmation button.

[0139] The processor (110) periodically checks the storage period of the content stored in memory (150) and can provide a notification to the user via the display (111) before the expiration date arrives. If the user enters an extension request, the processor (110) can control the content so that it is not deleted and is maintained by setting an additional storage period for the content. Conversely, if the user does not choose to extend, the content that has reached the expiration date is automatically deleted, or only the visualized representative information may be maintained.

[0140] In one embodiment, the extension of the storage period may be processed in conjunction with an external server (190). For example, when the video display device (100) transmits an extension request signal to the external server (190), the server (190) updates the storage policy of the content and supports the content to be accessible through the video display device (100) thereafter.

[0141] A video display device (100) according to one embodiment allows the user to efficiently utilize storage space while reliably storing necessary content through storage period management and expiration notification functions.

[0142] According to one embodiment, the processor (110) manages the retention period of content stored in memory (150) or an external server (190) and can provide a notification to the user before the scheduled expiration date. The notification may be provided in various forms, such as a pop-up window on the screen of the display (111), a notification icon on the status bar, a voice guidance message, and / or a push notification to an external electronic device (199). If the user selects a confirmation button or an extension button included in the notification, the processor (110) can update the retention period to ensure that the content is maintained without being deleted. Conversely, if the user does not extend, the content may be automatically deleted upon expiration, or only visualized representative information may be retained. In some embodiments, the extension request may be synchronized with the external server (190) so that the retention policy is updated in the same way in the server storage. This enables consistent data management between the user terminal, the server, and the video display device (100).

[0143] The image display device (100) according to the above-described embodiment provides a notification to the user before the expiration of the storage period of the content and can extend the storage period according to the user's choice.

[0144] FIG. 10 is a flowchart illustrating the process of re-receiving content by referring to location information of an external electronic device according to one embodiment.

[0145] Referring to FIG. 10, a procedure for re-acquiring and displaying content whose storage period has expired may include an operation of identifying the expired content (S1010), an operation of receiving location information from an external electronic device (199) (S1020), and an operation of re-downloading the content by referring to the location information and displaying it on a display (111) (S1030).

[0146] In operation S1010, the processor (110) can identify expired content by periodically checking the retention period of content stored in memory (150) or an external server (190). Expired content may be managed in a list, and whether it is available for re-reception may be displayed through a user interface while only visualized representative information is maintained. In some embodiments, the processor (110) may initiate a re-reception procedure if it accepts the user's request for re-reception after providing the notification shown in FIG. 9.

[0147] In operation S1020, the communication unit (130) may receive location information regarding the content from an external electronic device (199). The location information may include an identifier of the storage where the original is stored, an access path, resource identification information, and / or access permission information, and may be transmitted via direct communication with the external electronic device (199) or through communication via an external server (190). At this time, the processor (110) may verify the validity and access rights of the location information and, if necessary, perform procedures such as renewing the authentication token, resetting the session, and / or exchanging encryption parameters. If the location information is updated or an alternative path is provided, the processor (110) may manage to use the latest information preferentially.

[0148] In operation S1030, the processor (110) can control the communication unit (130) to re-receive content by referring to the received location information. Re-reception can be performed by a streaming method or a file download method, and depending on the network status, segment-by-segment retransmission, breakpoint resumption, and error recovery procedures can be performed. The re-received content can be temporarily or permanently stored in memory (150), and can be controlled to be immediately displayed on the display (111) or played upon user selection. Before the entire data is ready, visualized representative information can be displayed first, and the screen can be updated according to the reception progress. If access rights are restricted or a network error occurs, the processor (110) can set a retry schedule or provide a notification message to the user.

[0149] According to the above procedure, the video display device (100) can receive and display content again from a location by utilizing location information provided by an external electronic device (199), even for content whose storage period has expired. This has the effect of supporting users to access past content when needed while efficiently using storage space.

[0150] According to one embodiment, the processor (110) may receive location information of the content from an external electronic device (199) or an external server (190) to re-secure the content whose storage period has expired. The location information may include, for example, a file path or storage directory information, a cloud resource identifier, an access URL and authentication token, and the path and permission information of a network drive. After verifying the validity of the received location information, the processor (110) may control the communication unit (130) to re-download or stream the content from the designated location. At this time, segment-by-segment transmission, breakpoint resuming, and error recovery procedures may be performed depending on the network status. Before the entire data is received, visualized representative information may be displayed first, and the screen may be updated according to the reception progress. Through such procedures, the user can re-access the expired content by referring to the original storage location information, which can simultaneously provide long-term data management and user convenience.

[0151] The image display device (100) according to the above-described embodiment can receive expired content again by referring to location information provided from an external electronic device (199).

[0152] The video display device, system, and control method according to the above-described embodiment can independently receive and display content by linking with an external server, thereby enabling seamless content sharing while minimizing user intervention. In particular, since the display of content can be automatically controlled based on the power status and transmission time, the user can immediately view the content without turning on the power or setting a schedule.

[0153] By transmitting power status information to a server and managing the scheduled transmission time, location information, and / or identification information, content can be displayed appropriately at the scheduled time. Content for multiple users can be separated by user and classified and displayed according to type or content, and the corresponding classification menu can be automatically controlled if a specific type of content does not exist.

[0154] Stable data management is possible by providing notifications before the storage period expires and storage extension functions, and content whose storage period has expired can be re-retrieved by referencing location information from external electronic devices. Additionally, the status of shared spaces on external servers can be managed to provide users with the latest shared information, and storage resources can be utilized efficiently by downloading only the content selected by the user and retaining only representative information for unselected content.

[0155] When a user selects a specific account, content can be transmitted to an external electronic device linked to that account, enabling bidirectional sharing and expanded utilization of the content. Therefore, the invention according to the above-described embodiment can simultaneously achieve convenience in content sharing and management efficiency.

[0156] Although this specification has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of this specification should be determined by the technical spirit of the appended claims.
