Description

Display device, method of operation of display device, and recording medium

[0001] The present disclosure relates to a display device that provides a cue card capable of displaying different types of content and applications.

[0002] Digital TV services using wired or wireless communication networks are becoming commonplace. Digital TV services can provide a variety of services that were not available through existing analog broadcasting services.

[0003] For example, digital TV services such as IPTV (Internet Protocol Television) and smart TV provide interactivity that allows users to actively select the types of programs and viewing time. Based on this interactivity, IPTV and smart TV services can also provide various additional services, such as internet search, home shopping, and online games.

[0004] Recent TVs provide screen components that display summary information about key content and applications that are easily accessible to the user, such as Q cards.

[0005] Cue cards allow for the quick selection of various media, such as favorite programs, recommended content, and recently watched items, and play a role in enhancing the user experience through convenient navigation.

[0006] However, when requirements for conventional cue cards are proposed, even if data is provided by the server, developers must develop each component to meet those requirements, which results in a significant development period.

[0007] In addition, whenever a common UX scenario is added to each cue card, there is a burden of having to apply the same logic code to each other cue card.

[0008] In addition, there is a problem where the addition and deletion of necessary components due to server configuration do not operate dynamically but are developed statically.

[0009] The purpose of the present disclosure may be to efficiently provide a cue card capable of displaying different types of content and applications.

[0010] The purpose of the present disclosure may be to efficiently reflect requirements for cue cards when requirements for cue cards arise.

[0011] The purpose of the present disclosure may be to apply the added UX scenarios collectively through code standardization when common UX scenarios are added to cue cards.

[0012] The purpose of the present disclosure may be to allow the addition and deletion of components to a cue card to be applied dynamically.

[0013] A display device according to an embodiment of the present disclosure may include: a memory for storing a code of a universal cue card; a display; a network interface for communicating with a server; and a controller that receives a request to expose a cue card from the server, calls the code of the universal cue card stored in a preset execution path according to the received exposure request, generates a packaging file of the cue card based on the called code, and displays a cue card item corresponding to the cue card on the display based on the generated packaging file.

[0014] A method of operation of a display device according to an embodiment of the present disclosure may include: receiving a request to display a cue card from a server; calling a code of a universal cue card stored in a preset execution path according to the received request to display; generating a packaging file of the cue card based on the called code; and displaying a cue card item corresponding to the cue card based on the generated packaging file.

[0015] In a computer-readable recording medium storing a program for executing a method of operation of a display device according to an embodiment of the present disclosure, the method of operation

[0016] The method may include the steps of: receiving a request to display a cue card from a server; calling the code of a universal cue card stored in a pre-configured execution path according to the received request to display; generating a packaging file of the cue card based on the called code; and displaying a cue card item corresponding to the cue card based on the generated packaging file.

[0017] According to various embodiments of the present disclosure, when a new request is made for a cue card capable of displaying different types of content and applications, the cue card can be displayed on the home screen without a separate development period.

[0018] According to various embodiments of the present disclosure, a queue card may be displayed or hidden for a short period of time as an event at the request of a content provider.

[0019] According to various embodiments of the present disclosure, if there are changes to the cue card, it is possible to respond in real time by changing it from time to time through the manager.

[0020] According to various embodiments of the present disclosure, different types of cue cards can be generated with a single source code, thereby enabling memory savings.

[0092] If the user input interface (230) is equipped with a touchscreen, the user can input commands related to the display device (100) to the remote control device (200) by touching the soft keys on the touchscreen. Additionally, the user input interface (230) may be equipped with various types of input means that the user can operate, such as scroll keys or jog keys, and this embodiment does not limit the scope of the present invention.

[0093] The sensor (240) may be equipped with a gyroscope sensor (241) or an accelerometer sensor (243), and the gyroscope sensor (241) may sense information regarding the movement of the remote control device (200).

[0094] For example, the gyroscope sensor (241) can sense information regarding the operation of the remote control device (200) based on the x, y, and z axes, and the accelerometer sensor (243) can sense information regarding the movement speed of the remote control device (200). Meanwhile, the remote control device (200) may further be equipped with a distance measuring sensor to sense the distance to the display (180) of the display device (100).

[0095] The output interface (250) can output a video or audio signal corresponding to the operation of the user input interface (230) or a signal transmitted from the display device (100).

[0096] The user can recognize whether the output interface (250) is operated by the user input interface (230) or whether the display device (100) is controlled.

[0097] For example, the output interface (250) may be equipped with an LED (251) that lights up when the user input interface (230) is operated or when a signal is transmitted or received with the display device (100) through the wireless communication circuit (220), a vibrator (253) that generates vibration, a speaker (255) that outputs sound, or a display (257) that outputs video.

[0098] Additionally, the power supply circuit (260) supplies power to the remote control device (200), and can reduce power waste by stopping the power supply when the remote control device (200) does not move for a predetermined period of time.

[0099] The power supply circuit (260) can resume power supply when a predetermined key provided in the remote control device (200) is operated.

[0100] The memory (270) can store various types of programs, application data, etc. required for the control or operation of the remote control device (200).

[0101] When the remote control device (200) transmits and receives signals wirelessly through the RF circuit (221) and the display device (100), the remote control device (200) and the display device (100) transmit and receive signals through a predetermined frequency band.

[0102] The controller (280) of the remote control device (200) can store and refer to information regarding frequency bands, etc., that can wirelessly transmit and receive signals with the display device (100) paired with the remote control device (200) in the memory (270).

The controller (280) can transmit a signal corresponding to a predetermined key operation of the user input interface (230) or a signal corresponding to the movement of the remote control device (200) sensed by the sensor (240) to the display device (100) through the wireless communication circuit (220).

[0104] In addition, the microphone (290) of the remote control device (200) can acquire voice.

[0105] The microphone (290) may be provided in multiple numbers.

[0106] Next, Figure 4 is explained.

[0107] Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

[0108] FIG. 4(a) illustrates a pointer (205) corresponding to a remote control device (200) being displayed on a display (180).

[0109] The user can move or rotate the remote control device (200) up and down, left and right. The pointer (205) displayed on the display (180) of the display device (100) corresponds to the movement of the remote control device (200). Since the pointer (205) of the remote control device (200) moves and is displayed according to the movement in 3D space as shown in the drawing, it can be named a spatial remote control.

[0110] FIG. 4(b) illustrates that when the user moves the remote control device (200) to the left, the pointer (205) displayed on the display (180) of the display device (100) also moves to the left in response.

[0111] Information regarding the movement of the remote control device (200) detected through the sensor of the remote control device (200) is transmitted to the display device (100). The display device (100) can calculate the coordinates of the pointer (205) from the information regarding the movement of the remote control device (200). The display device (100) can display the pointer (205) to correspond to the calculated coordinates.

[0112] FIG. 4(c) illustrates a case where, while pressing a specific button within the remote control device (200), the user moves the remote control device (200) away from the display (180). By doing so, the selected area within the display (180) corresponding to the pointer (205) can be zoomed in and enlarged.

[0113] Conversely, when the user moves the remote control device (200) closer to the display (180), the selected area within the display (180) corresponding to the pointer (205) can be zoomed out and reduced in size.

[0114] Meanwhile, when the remote control device (200) moves away from the display (180), the selected area may be zoomed out, and when the remote control device (200) moves closer to the display (180), the selected area may be zoomed in.

[0115] Additionally, when a specific button within the remote control device (200) is pressed, recognition of up-down and left-right movement may be excluded. That is, when the remote control device (200) moves away from or closer to the display (180), up-down, left-right movement is not recognized, and only forward-backward movement is recognized. When the specific button within the remote control device (200) is not pressed, only the pointer (205) moves according to the up-down, left-right movement of the remote control device (200).

[0116] Meanwhile, the movement speed or direction of movement of the pointer (205) can correspond to the movement speed or direction of movement of the remote control device (200).

[0117] Meanwhile, the pointer in this specification refers to an object displayed on the display (180) in response to the operation of the remote control device (200). Accordingly, the pointer (205) can be an object of various shapes other than the arrow shape shown in the drawing. For example, it may be a concept including a point, a cursor, a prompt, a thick outline, etc. Furthermore, the pointer (205) can be displayed corresponding to either a point on the horizontal axis or a vertical axis on the display (180), and it is also possible to display it corresponding to multiple points, such as a line or a surface.

[0118] In the following description, a cue card may be a screen component that displays summary information about key content and applications that are easily accessible to the user. A cue card may be an application installed on a display device (100). A cue card may be referred to as a cue card application or a cue card app.

[0119] FIG. 5 is a drawing illustrating the configuration of a system according to one embodiment of the present disclosure.

[0120] Referring to FIG. 5, the system (50) may include a management server (510), a Service Delivery Platform (SDP) server (520), an Advertising Delivery Platform (ADP) server (530), and a display device (100).

[0121] The management server (510) can transmit queue card information to the SDP server (520).

[0122] The SDP server (520) can transmit a cue card exposure request based on cue card information to the display device (100).

[0123] The display device (100) can execute the code of a universal cue card stored in a pre-configured path in response to a cue card exposure request received from the SDP server (520).

[0124] The display device (100) can generate a packaging file according to the execution of the code of the universal cue card and can display a cue card item corresponding to the cue card on the home screen based on the packaging file.

[0125] The display device (100) can send a content information request corresponding to the cue card to the SDP server (520).

[0129] The ADP server (530) can transmit an advertisement to be displayed on a banner screen included in the execution screen of a cue card to the display device (100). The ADP server (530) can transmit one or more of an advertisement video, advertisement text, or advertisement image to be displayed on a banner screen to the display device (100) according to a command from the SDP server (520) or a command from the management server (510).

[0130] FIG. 6 is a sequence diagram for explaining the operation method of a system according to one embodiment of the present disclosure.

[0131] Referring to FIG. 6, the management server (510) can transmit queue card information to the SDP server (520) (S601).

[0132] In one embodiment, the cue card information may include at least one of information about content contracted with a content provider, the number of cue cards organized, the title of the cue card, country information, banner information, and component organization information.

[0133] Cue card information can be organized by a management server (510). Cue card information may be referred to as cue card organization information. Component organization information may include one or more of the presence or absence of a component, the number of components, and the rank information of the components.

[0134] The SDP server (520) can transmit a request for cue card exposure based on cue card information to the display device (100) (S603).

[0135] The SDP server (520) can select a display device (100) located in the country of the country information included in the cue card information.

[0136] The SDP server (520) can determine the range of content and applications that can be provided on the cue card based on the specifications of the selected display device (100). The SDP server (520) may store information about the specifications of the display device (100) in advance.

[0137] In one embodiment, the cue card display request may be a request to display a cue card on the home screen. The cue card display request may be a request to create a cue card and display it on the home screen. The cue card display request may include the number of cue cards to be displayed and the title of the cue card.

[0138] The controller (170) of the display device (100) can execute the code of a universal cue card stored in a pre-configured path in response to a cue card exposure request received from the SDP server (520) (S605).

[0139] In one embodiment, the pre-configured path may be a path where the code of a pre-configured universal cue card is stored.

[0140] The controller (170) can execute the code of the universal cue card by accessing a pre-configured path (main path) within a JSON file (or appInfo.json file) corresponding to the cue card. The code of the universal cue card and an index.html file may be stored in memory (140).

[0141] The code and index.html file can be saved in a storage location that matches the universal cue card among multiple cue cards.

[0142] The code of a general-purpose cue card consists of components such as scripts or stylesheets that control the functions of the cue card (or cue card app), and may include commands for user interface behavior and data processing logic.

[0143] The index.html file may be a file used to call the code of a universal cue card to display a cue card entry corresponding to the cue card or the execution screen of the cue card.

[0144] The controller (170) can redirect to a path where the code of a pre-configured universal cue card is stored in response to the exposure of the cue card.

[0145] Figure 7 is a diagram showing that the execution path of the JSON file of each cue card is set to the path where the code of the universal cue card is stored.

[0146] Referring to FIG. 7, when the display device (100) receives a request to display the first cue card (710) among the first to fourth cue cards (710 to 740), it can generate a packaging file of the first cue card (710) using the code of the universal cue card (700).

[0147] That is, only the general-purpose cue card (700) has the source code, and the first to fourth cue cards (710 to 740) do not have the source code.

[0148] Accordingly, whenever the requirements for the first cue card (710) increase, a packaging file is created, but the source code does not need to be included, and an appInfo.json file, an icon of the cue card, information of the cue card (e.g., the color of the cue card icon), a splash image, and a background image of the cue card may be added.

[0149] Again, Figure 6 is explained.

[0150] The controller (170) of the display device (100) can generate a packaging file according to the execution of the code of the universal cue card (S607), and based on the packaging file, can display a cue card item corresponding to the cue card on the home screen of the display (180) (S609).

[0151] The controller (170) can compile and package (or build) the code of the executed universal cue card to generate a package file (ipk). The package file may be referred to as an app package file. The package file may include resources necessary for the execution of the cue card, such as HTML files, images, scripts, and JSON files.

[0152] The controller (170) can display a cue card item corresponding to the cue card on the home screen of the display (180) based on the packaging file.

[0153] Each cue card item can have a unique icon, icon color, splash image, and cue card image.

[0154] The controller (170) of the display device (100) can transmit a request for content information corresponding to the cue card to the SDP server (520) through the network interface (133) (S611).

[0155] A content information request may be a request to receive information about content to be provided according to the execution of the queue card. A content information request may be a request for a list of components provided through the queue card.

[0156] The controller (170) can identify the identifier (ID) of the currently running queue card and can send the identifier of the queue card to the SDP server (520) along with a content information request.

[0157] The identifier of the queue card may also be included in the content information request.

[0158] The controller (170) of the display device (100) can receive content information corresponding to the cue card from the SDP server (520) through the network interface (133) (S613).

[0159] The SDP server (520) can obtain content information matched to an identifier based on the identifier of the queue card. The SDP server (520) may store multiple identifiers corresponding to each of the multiple queue cards. The SDP server (520) may store multiple content information matched to each of the multiple identifiers.

[0160] Each content information may include at least a portion of the cue card information organized by the management server (510).

[0161] Content information may include information about one or more components.

[0162] One or more components may include a banner, an app list, a shelf list, and a tab list.

[0163] A banner can be a component for providing advertisements displayed at the top of the home screen.

[0164] An app list may be a component that lists multiple applications and allows the user to select one.

[0165] A shelf list can be a component for displaying multiple contents provided by multiple content providers.

[0166] A tab list can be a component that distinguishes content provided by each content provider.

[0167] Information about one or more components may include information about advertisements provided through banners, information about multiple apps provided through app lists, information about multiple contents provided through shelf lists, and information about multiple contents provided through tab lists.

[0168] Information about multiple contents is information about each content and may include one or more of a thumbnail image of the content or the title of the content.

[0169] Content information may further include rank information for each component. Rank information may be information indicating the placement position where each component is displayed. Rank information may include the exposure order of the components. The earlier the exposure order, the higher it may be displayed, and the later the exposure order, the lower it may be displayed.

[0170] Rank information can be received separately from content information.

[0171] Content information may further include the presence or absence of banners, the number of app lists, the number of shelf lists, and the number of tab lists.

[0172] The controller (170) of the display device (100) can generate a component list based on the received content information (S615).

[0173] The controller (170) can generate a component list containing a plurality of components arranged based on rank information included in the content information.

[0174] The controller (170) can generate a cue card execution screen using the code, index.html file, and content information of the universal cue card. The cue card execution screen may include a component list.

[0175] The controller (170) of the display device (100) can display the generated component on the display (180) according to the selection of the cue card (S617).

[0176] FIGS. 8A and 8B are drawings illustrating the process of displaying a cue card on a home screen according to one embodiment of the present disclosure.

[0177] The management server (510) can organize cue card information contracted with one or more content providers (CP) and transmit it to the SDP server (520).

[0178] The cue card information may include at least one of the following: information about the content, the number of cue cards organized, the title of the cue card, country information, banner information, and component organization information.

[0179] Through the settings, you can dynamically organize various content by country and content provider using queue cards, and queue cards can be displayed or hidden on the home screen.
