Example 1

In order to expand the local data that can be directly used by the display device 200 without occupying the storage space of the display device 200 itself, and to enrich the flexibility of the display device 200 to acquire data, an external device may be connected to the display device 200, and for different requirements of a user, the user may connect different types of external devices, such as a usb disk, a mobile hard disk, a DLNA device, and the like, to the display device 200. The display device 200 generally sets a DMP application to manage these external devices, the user moves the focus to an option of the DMP application by manipulating the control apparatus 100, and sends an application selection instruction to the display device 200 by pressing the "confirm" button, and the display device 200 displays a user interface of a subordinate menu corresponding to the DMP application, that is, a list of the external devices shown in fig. 1, in response to the application selection instruction. In some embodiments, the external device list includes icons and device names of all external devices currently connected to the display device 200, in order to distinguish different types of external devices, the different types of external devices correspondingly display different icons, as shown in fig. 1, the display device 200 is currently connected to three external devices, namely, a "first external device", a "second external device", and a "third external device", where the "first external device" and the "second external device" are external devices of the same type, such as a usb disk, and the "third external device" is an external device of a different type, such as a DLNA device. The user can quickly and accurately know the device information of the external device currently connected with the display device 200 through different icons and device names. In some embodiments, if there are some external devices that cannot be used in all the external devices currently connected to the display device 200, the icons and device names corresponding to these external devices that cannot be used will be provided with prompt identifiers, such as graying-out not selectable, highlighting, etc., to prompt the user that these external devices are not available.

Further, the user may select the external device to be viewed through the operation control device 100, as shown in fig. 7, taking the remote controller as an example, the user moves the focus to the icon and the device name corresponding to the first external device by operating the "up", "down", "left", and "right" keys on the remote controller, and the user sends an application selection instruction to the display device 200 by pressing the "confirm" key on the remote controller, so as to select the first external device. The display device 200 displays a user interface corresponding to the content of the first external device in response to the application selection instruction, as shown in fig. 8(1), where the content of the first external device includes a folder a, a folder b, and a folder c. In this embodiment, the content of the external device refers to data stored in the external device, where the data stored in the external device corresponds to different user interfaces according to each storage node in the storage path thereof, for example, "picture a" stored in the external device, and the corresponding storage path is "folder a → folder a '", then each storage node corresponding to "picture a" is "folder a" and "folder a'", respectively, and the user controls the control device 100 to sequentially enter the corresponding user interfaces according to the storage path of "picture a" to find "picture a". Accordingly, the display apparatus 200 sequentially displays, in response to an instruction of the user, a user interface (including contents in folder a, i.e., folder a ' and folder a ') corresponding to the storage node "folder a" as shown in fig. 8(2), and a user interface (including "picture a" and "music a") corresponding to the storage node "folder a '" as shown in fig. 8 (3).

When the user interface shown in fig. 8(3) is displayed, if the user wants to view the content of another external device, for example, the content of the second external device, the user may manipulate the control device 100 to send a return instruction to the display device 200, at this time, the display device 200 directly exits the DMP application, i.e., displays the desktop of the display device 200, in response to the return instruction, the user needs to reselect the DMP application to enter the external device list shown in fig. 1, and select the second external device from the external device list to browse the content of the second external device. Alternatively, the number of the return instructions is multiple, and the display device 200 sequentially displays the user interfaces shown in fig. 8(2), fig. 8(1) and fig. 1 in response to each return instruction to go back to the external device list, and then selects the second external device from the external device list to browse the content of the second external device.

It can be seen that if the content of the external device is displayed according to the above process, multiple interactions between the user and the display device 200 are required, and in the process of displaying the content of other external devices, the content of the current external device cannot be continuously displayed, which may result in that the user cannot continuously browse the content of the current external device. In order to solve the above problem, an embodiment of the present application provides a method for displaying content of an external device, which refers to a flow shown in fig. 9, and specifically includes the following steps:

s901, receiving a first control instruction sent by a user on a first user interface, where the first user interface is a user interface corresponding to the content of a first external device, and the first control instruction is used to instruct to display a first shortcut list, where the first shortcut list includes device names of all external devices of the display device.

In this embodiment, the first user interface is a user interface corresponding to the content of the current external device, for example, taking the first external device as the current external device, where the first user interface refers to a user interface corresponding to each storage node in the first external device, for example, a user interface corresponding to "folder a'", that is, the first user interface is shown in fig. 8 (3).

When the first user interface is displayed, if a user needs to browse the content of other external devices, such as a second external device, a first control instruction may be directly sent to the display device 200 on the first user interface, where the first control instruction is used to instruct the display device 200 to display the first shortcut list.

In this embodiment, the first control instruction may correspond to one or more different kinds of interaction information, and it should be noted that the interaction information is different from the interaction information corresponding to the instruction for triggering the original function on the first user interface. The process of the display device 200 receiving the first control instruction sent by the user specifically includes:

the display device 200 prestores a corresponding relation between a first control instruction and interactive information, after receiving the interactive information sent by a user, the display device 200 compares the received interactive information with the interactive information in the prestored corresponding relation, if the received interactive information belongs to the interactive information in the corresponding relation, the display device determines that the interactive information sent by the user is the first control instruction, and if not, the display device determines that the interactive information sent by the user is not the first control instruction.

In some embodiments, the interaction information corresponding to the first control instruction may be key value information of a specified key combination. Illustratively, the key value information specifying the key combinations as "< and" < i.e., "two consecutive key values corresponding to'", i.e., specifying the key combinations. As shown in fig. 10(1), the user transmits the interaction information "key value information" to the display apparatus 200 by pressing the "key" twice consecutively on the remote controller: ' Key value, ' Key value ', i.e. the first control instruction. In this embodiment, the key value information of the designated key combination at least includes the key value of each designated key, the order of each designated key, the input time interval between two adjacent designated keys, and the like.

In some embodiments, the interaction information corresponding to the first control instruction may be key value information of a designated key. The designated key may be an existing key on the control device 100 or a newly provided key. For example, the designated key may be an original key "on the control device 100, or may be a newly provided key" shortcut "on the control device 100, and the" shortcut "is dedicated to sending the first control command. In general, in order to avoid overlapping with the original function when the original key is used as the designated key, the pressing time may be set as the key value information of the designated key at the same time, and the first control instruction may be triggered only after the user continuously presses the designated key for a certain time. Illustratively, the user transmits the interaction information "key value information" to the display apparatus 200 by continuously pressing a designated key "<" 5 seconds on the remote controller: ' Key value, Press time: 5s ", i.e. the first control instruction. In this embodiment, the key value information of the designated key at least includes the key value of the designated key and the pressing time.

In some embodiments, the interaction information corresponding to the first control instruction may be the designated focus information. The first control instruction can be triggered only when the focus is located in a designated area of the user interface and a designated instruction is issued to the focus. Illustratively, the designated focus information is the information of the designated indication "key-value information" issued to the focus (as "identifier in (c)): 'Key value'. As shown in fig. 10(2), the user first operates the remote controller through the operation shown in (i), for example, presses the "button," moves the focus to the designated area S on the first user interface, and then presses the "button" once through the operation shown in (ii), and issues the designated indication "key value information: 'key value' to send the interactive information "key value information: 'Key value', i.e. the first control instruction. At this time, the display apparatus 200 recognizes that the user transmits the first control instruction by recognizing the position of the focus on the first user interface and the interactive information.

In some embodiments, the interaction information corresponding to the first control instruction may be specified voice information. Illustratively, the voice information is designated as "open first shortcut list". In some embodiments, the first control instruction corresponds to the designated gesture information. Illustratively, the display screen of the display device 200 is a touch-sensitive screen, and may sense a gesture operation of the user, and the designated gesture information is sliding from a designated area of the first user interface, for example, a right boundary, along a designated direction, for example, sliding to an inner side of the first user interface.

The above only shows the mutual information of the first control instruction by way of example, and of course, other mutual information may be used as the mutual information of the first control instruction. Further, in order to provide more flexible and various choices for the user, the above interaction information may be used as the interaction information of the first control instruction at the same time, and the user only needs to select one of the interaction information to send the first control instruction.

S902, responding to the first control instruction, and displaying the first shortcut list on the first user interface.

The display apparatus 200 displays the first shortcut list on the first user interface as shown in fig. 11 in response to the first control instruction. The first shortcut list includes device names of all external devices of the display device 200, such as "first external device", "second external device", and "third external device". The user can quickly and accurately know all external devices currently connected to the display device 200 by browsing the first shortcut list, and can directly select a second external device to be displayed from the first shortcut list.

In some embodiments, the first shortcut list may be displayed at a preset location on the first user interface, such as the left side of the first user interface shown in fig. 11. In some embodiments, a display position of the first shortcut list on the first user interface may correspond to the interaction information of the first control instruction, for example, the interaction information shown in fig. 10(2), at this time, the first shortcut list is displayed on the right side of the first user interface corresponding to the operation on the right side of the first user interface.

In the embodiment of the application, the first shortcut list and the first user interface are two different layers, the first shortcut list is arranged on the first user interface, and the first shortcut list and the first user interface can be displayed simultaneously. Furthermore, because the display of the first shortcut list can block part of the content of the first user interface, the first shortcut list can be set as a movable list, that is, the first shortcut list is randomly moved on the layer where the first shortcut list is located, and by moving the first shortcut list, part of the content of the first user interface blocked by the first shortcut list is exposed, so as to meet the browsing requirement of the user. The two layers are used for simultaneously displaying the first shortcut list and the first user interface, and when the first shortcut list is displayed, the display of the first user interface does not need to be adjusted, so that the display device 200 is prevented from generating extra display calculation. Moreover, once the user performs the misoperation instruction to expand the first shortcut list, the user can also close the first shortcut list by sending the cancel instruction and directly expose the first user interface, so that the response speed of the display device 200 to the cancel instruction is faster.

In a special display mode, the first shortcut list may completely cover the first user interface, and although the form of the first shortcut list is similar to that of the user interface of the external device list shown in fig. 1, the first shortcut list and the first user interface are located in different layers, that is, the first shortcut list and the first user interface are still in a state of being displayed simultaneously, instead of exiting from the first user interface, only the first shortcut list is displayed. At this time, when the first shortcut list is closed, the first user interface located below the layer of the first shortcut list may still be directly displayed without the display device 200 performing an operation on displaying the first user interface again.

S903, receiving a first selection instruction sent by the user, wherein the selection instruction is used for indicating and displaying the content of a second external device, and the device name of the second external device belongs to the first shortcut list.

As shown in fig. 12 ((r)), the user moves a focus (a bold black line frame) to an option of the second external device by manipulating the control apparatus 100, for example, by pressing an "up" key and a "down" key on the remote controller, and transmits a first selection instruction to the display device 200 by pressing an "ok" key, the first selection instruction being used to instruct the display device 200 to display a user interface, i.e., a second user interface, corresponding to the content of the selected external device (in this embodiment, the second external device).

And S904, responding to the first selection instruction, and switching the first user interface into a second user interface, wherein the second user interface is a user interface corresponding to the content of the second external device.

In response to the first selection instruction, the display device 200 directly replaces the first user interface with the second user interface, i.e., completely exits the first external device, and displays only the second user interface, as shown in fig. 12, where the second user interface includes the contents of the second external device, such as "folder d" and "folder e".

Further, if the user wants to browse the content of other external devices (including the first external device) while displaying the second user interface, the process similar to the above process may be referred to, and the display device 200 is controlled to display the first shortcut list, and the external device with the content to be browsed is selected from the first shortcut list, which is not described herein again.

In some embodiments, when the user browses the current user interface and wants to browse the content of the external device browsed in the history again, for example, when the user browses the second user interface and wants to browse the content of the first external device again, the user may be configured to directly display the first user interface of the first external device, where the first user interface is the last user interface displayed when the user exits the first external device. Reference may be made to the following scheme:

s1301, responding to the first selection instruction, and recording the first user interface.

The display device 200 receives the first selection instruction, and before switching the first user interface to the second user interface, first stores the first user interface, for example, the first user interface shown in fig. 8(3), and then switches the first user interface to the second user interface shown in fig. 12.

S1302, receiving the first control instruction sent by the user on the second user interface.

S1303, responding to the first control instruction, and displaying the first shortcut list on the second user interface.

And S1304, receiving a second selection instruction sent by the user, wherein the second selection instruction is used for indicating and displaying the content of the first external device.

The steps of S1302 to S1304 may refer to the steps of S901 to S903, and are not described herein again. As shown in fig. 13 (i), a first shortcut list including device names of all external devices, for example, "first external device", "second external device", and "third external device", is displayed on the second user interface. The focus is moved to the item of the "first external device" to send a second selection instruction to the display device 200, i.e., to instruct to display the content of the first external device.

S1405, responding to the second selection instruction, acquiring the first user interface, and switching the second user interface into the first user interface.

In response to the second selection instruction, the display device 200 first determines whether the first external device is a historical external device, that is, an external device that the user has browsed through. If the first external device is judged to be a historical external device, the stored first user interface, namely the first user interface shown in fig. 8(3), is obtained, and the second user interface is directly switched to the stored first user interface, as shown in fig. 13, the displayed content is the first user interface shown in fig. 8(3) which is stored in advance.

In order to facilitate the user to quickly know the content of each external device so that the user can accurately select the external device to be browsed, the display device 200 may display preview information of each external device, and refer to the following process:

s1401, receiving a browsing instruction sent by the user on the first shortcut list, wherein the browsing instruction indicates an external device to be browsed, and the device name of the external device to be browsed belongs to the first shortcut list.

Taking the first shortcut list and the first user interface shown in fig. 11 currently displayed by the display device 200 as an example, according to the operation shown in fig. 14, the user sends a browsing instruction to the display device 200 by operating the control device 100, for example, a remote controller, in this embodiment, the browsing instruction is an instruction indicating an external device to be browsed, and is different from an instruction indicating content of the external device, such as a first selection instruction and a second selection instruction. In this embodiment, the external device to be displayed with the preview information may be defined as the external device to be browsed. As shown in fig. 14, the user moves the focus to the item of the second external device by manipulating the remote controller, and instructs the external device to be browsed, that is, the second external device, through the focus, so as to send a browsing instruction to the display device 200.

S1402, responding to the browsing instruction, displaying a sub-list on the first user interface, wherein the sub-list corresponds to the position of the external device to be browsed in the first shortcut list, and the sub-list comprises preview information of the external device to be browsed.

In response to the browsing instruction, the display device 200 displays a sub-list on the first user interface, as shown in fig. 14, where the sub-list includes preview information of the external device to be browsed. The sub-list, the first shortcut list and the first user interface are respectively positioned on different layers, and the sub-list is displayed on the layer where the first shortcut list is positioned. The sub-list generally corresponds to the position of the external device to be browsed in the first shortcut list, as shown in fig. 14, the sub-list is located on the right side of the item of the second external device, and the corresponding relationship between the sub-list and the external device to be browsed can be displayed through the corresponding relationship between the sub-list and the position of the external device to be browsed in the first shortcut list, so that a user can quickly and accurately know which external device the currently displayed sub-list corresponds to. The sub-list can also be directly covered in an area where the items of the external equipment to be browsed are displayed on the first shortcut list, and the user is prompted to which external equipment the currently displayed sub-list corresponds through the covering relation. In this embodiment, because the sub-list, the first shortcut list, and the first user interface are located in different layers, the sub-list, the first shortcut list, and the first user interface may be displayed simultaneously, and the display device 200 may directly close the list or the user interface on the layer by deleting the corresponding layer, without affecting the display of the lists or the user interfaces on other layers, and the display device 200 does not need to perform repeated display operations, which may effectively reduce the operation pressure of the display device 200. For example, when a user mistakenly operates and sends a browsing instruction to the display device 200, and displays a sub-list of an external device to be browsed, for example, a sub-list of a second external device, a cancel instruction may be sent, for example, a remote controller is manipulated to move a focus away from an item of the second external device, and the display device 200 directly closes a layer where the sub-list is located in response to the cancel instruction, so as to close the sub-list and directly expose the first shortcut list and the first user interface, without the display device 200 performing a related display operation in the exposing process.

Further, if the user wants to browse the preview information of other external devices, the browsing instruction may be sent to the display device 200 again according to the above procedure to display a sub-list of other external devices.

In this embodiment, the sub-list includes preview information of the external device to be browsed, where the preview information is used to generally display the content of the external device to be browsed. In some embodiments, the preview information may be the number of folders in the external device to be browsed, the capacity information of the external device to be browsed, names of designated folders in the external device to be browsed, names of designated data in the external device to be browsed, and the like, as shown in fig. 14, the preview information displayed in the sub-list of the second external device includes names of folders, namely "folder d" and "folder e", of the second external device. The preview information of the external device to be browsed can be preset as required, and can also be edited according to subsequent requirements, which is not limited in the embodiment of the application.

The content of each external device is displayed through the above process, and after a certain external device is selected, the content that the user really wants to browse is displayed step by step through multiple interactions between the user and the display device 200, for example, a "picture B" located on the 3 rd page in the second external device is displayed, then the display device 200 needs to respond to an instruction sent by the user to sequentially display the user interface (including a "folder d" and a "folder e") of the 1 st page in the second external device, the user interface (being the subordinate user interface of the "folder d" and including a "folder d '" and a "folder d" ") of the 2 nd page in the second external device, and the user interface (being the subordinate user interface of the" folder d' "and including an item of the" picture B ") of the 3 rd page in the second external device. In order to improve the display efficiency of the content of the external device and reduce the number of interactions between the user and the display device 200, a skip key may be added to the first shortcut list.

In some embodiments, the skip key may be used to indicate that a specified page in a specified external device is displayed. In this embodiment, the external device is an external device corresponding to the first shortcut list, and for example, if the first shortcut list is displayed when the first user interface of the first external device is displayed, the first external device is the external device. In this embodiment, the jump key has a text (number) input area, as shown in fig. 15, "jump to _ page", where the "_" area is the text (number) input area, the user moves the focus to the jump key through the control device 100, and continues to control the control device 100 to input a page number corresponding to the content to be displayed, for example, "3", taking the external device as the second external device, and "3" indicates the display device 200 to directly display the content corresponding to the 3 rd page in the second external device. The display device 200 prestores a corresponding relationship between a page number in each external device and a content corresponding to the page number, and the display device 200 determines the content corresponding to the 3 rd page according to the prestored corresponding relationship in response to the jump instruction, and displays a second user interface corresponding to the content, which includes a project of "picture B" in the above example. Therefore, the content of a certain page in the specified external device can be directly displayed through the jump key, so that the interaction times between the user and the display device 200 are effectively reduced, and the experience of the user is improved.

In this embodiment, the content corresponding to the page 1 of the specified external device is usually the entry of other content in the specified external device, in some cases, the corresponding content will only correspond to part of the content in the specified external device starting from the page 2 of the specified external device, for example, the content corresponding to the page 1 of the specified external device is "folder d" and "folder e", the content corresponding to the page 2 is "folder d'" and "folder d" "in the" folder d ", and obviously, the content of the" folder e "is lacked starting from the page 2. Accordingly, as shown in fig. 15, the jump key may also be used to instruct the display device 200 to display a user interface corresponding to the content of the page 1 of the specified external device, for example, a jump key "Back to the first page", through which the user transmits a jump instruction to the display device 200, and the display device 200 directly displays the user interface of the page 1 of the specified external device in response to the jump instruction.

In some embodiments, if the user does not know the page number of the folder to be browsed in the designated device, the user cannot jump directly to the corresponding user interface through the jump key. At this time, as shown in fig. 15, a Search (Search) key may be set in the first shortcut list, the user sends a first Search instruction to the display device 200 through the Search key, the display device 200 displays a Search interface in response to the first Search instruction, the Search interface is used to input a name of a folder or data to be searched, the user sends a second Search instruction to the display device 200 by inputting a corresponding name in the Search interface, and the display device 200 directly displays a user interface of a page where the folder or data corresponding to the name is located in response to the second Search instruction.

In some embodiments, as shown in fig. 15, a first Edit key, such as an Edit (Edit) key, for instructing to start a function of editing items in the first shortcut list may be provided in the first shortcut list. A user sends a first editing instruction to the display device 200 through a first editing key, and the display device 200 changes items in the first shortcut list in response to the first editing instruction, that is, operations such as deleting and hiding each item in the first shortcut list may be performed, or an item may be added to the first shortcut list. For example, "Back to the first page" or the like is deleted from the first shortcut list. Alternatively, an item is added to the first shortcut list, for example, the display device 200 responds to a first editing instruction, at this time, the first editing instruction is used for instructing to add a target item to the first shortcut list, the display device 200 displays an item list including all items that can be added to the first shortcut list, and a user can select the target item from the item list to add to the first shortcut list.

In the above embodiment, the display device 200 may directly display the first shortcut list on the current user interface in response to the first control instruction sent by the user, and further display a user interface corresponding to the content of the external device in response to an instruction sent by the user based on the first shortcut list, so as to improve the efficiency of the display device 200 displaying only the user interface of one content in the external device. For example, a user interface that displays only the contents of page 3 of the second external device.

Example 2

Based on embodiment 1, it is possible to display other content while the display device 200 displays the content of the current user interface by the flow shown in fig. 16.

In this embodiment, the content displayed by the current user interface may be defined as main content, wherein the main content may be presented in parallel with other content, and the other content presented in parallel with the main content may be defined as sub-content, that is, the display device 200 may simultaneously run different threads corresponding to the main content and the sub-content to present the main content and the sub-content at the same time.

S1601, receiving a second control instruction sent by the user on the first user interface, where the second control instruction is used to instruct to display a second shortcut list, and the second shortcut list includes sub-content that can be displayed in parallel with the main content in the first external device.

Taking the first user interface as the current user interface for explanation, as shown in (r) in fig. 17, the content displayed by the first user interface is "picture a" that can be presented simultaneously with other content. The user sends a second control instruction to the display device 200 by manipulating the control apparatus 100, where the second control instruction is used to instruct the display device 200 to directly display the second shortcut list on the first user interface. The mutual information corresponding to the second control instruction may refer to the mutual information corresponding to the first control instruction in embodiment 1, and it should be noted that the mutual information corresponding to the second control instruction is different from the mutual information corresponding to the first control instruction, so as to distinguish the first control instruction from the second control instruction. Illustratively, the interaction information of the second control instruction is key value information of a designated key, as shown in (r) in fig. 17, the designated key is a "background music" key 400 on the first user interface, and the user moves the focus to the "background music" key 400 by manipulating the control apparatus 100 and presses an "confirm" key on the control apparatus 100 to send the key value information "background music", i.e., the second control instruction, to the display device 200. In other embodiments, other interaction information may be set as the interaction information of the second control instruction, and the user sends the second control instruction by sending corresponding interaction information to the display device 200, which is not listed here.

S1602, responding to the second control instruction, and displaying the second shortcut list on the first user interface.

The display apparatus 200 directly displays the second shortcut list on the first user interface as shown in fig. 17 in response to the second control instruction. In this embodiment, the second shortcut list and the first user interface are located in different layers, and the display relationship between the second shortcut list and the first user interface may refer to the display relationship between the first shortcut list and the first user interface in embodiment 1, which is not described herein again.

In this embodiment, the second shortcut list includes all sub-contents that can be concurrently displayed with the main content in the current external device. The current external device refers to an external device currently displaying content, and in the above example, the current external device is a first external device corresponding to the currently displayed content (the first user interface).

S1603, receiving a first editing instruction sent by the user on the second shortcut list, where the first editing instruction is used to indicate to display target sub-content.

In one implementation, as shown in fig. 17, the second shortcut list includes all sub-content that can be currently presented simultaneously with the main content "picture a", for example, the names of "music 1", "music 2", and "music 3".

The user may send a first editing instruction to the display apparatus 200, the first editing instruction being for instructing to present the target sub-content. For example, the user moves the focus to an item of the target sub-content by manipulating the control device 100, as shown in fig. 17 (c), moves the focus to "music 2", and selects "music 2" by pressing the "confirm" key on the control device 100, and moves the focus to a function key on the second shortcut list, for example, the "Play (Play)" key, and sends a first edit instruction, i.e., plays "music 2", to the display apparatus 200 by pressing the "confirm" key on the control device 100.

Further, a list to be presented, for example, a "music list" including names of all target sub-contents may be displayed after a list to be presented is created for the selected target sub-contents before the first editing instruction is sent to the display apparatus 200, for example, after "music 2" is selected according to the above process, and at this time, the user sends a first editing instruction to the display apparatus 200 based on the function key "play" key to instruct to play all target sub-contents according to the list to be presented.

In another implementation manner, the second shortcut list includes sub-content to be displayed that has been screened from all the sub-content in advance, for example, a "music list" shown as fifthly in fig. 17, and the second shortcut list is a "music list" and includes sub-content to be displayed, namely "music 1" and "music 3".

The user may send a first editing instruction to the display apparatus 200, the first editing instruction being for instructing to present the target sub-content. For example, the user moves the focus to a function key on the second shortcut list, such as a "play" key, by manipulating the control device 100, and sends a first editing instruction to the display apparatus 200 by pressing a "confirm" key on the control device 100, indicating that all the sub-contents to be presented, i.e., "music 1" and "music 3" are presented.

Further, the user can edit the second shortcut list to display and change the sub-content to be displayed. Illustratively, the user sends a first editing instruction to the display device 200 to indicate that the target sub-content is presented. At this time, the first editing instruction includes a plurality of instructions.

In some embodiments, the user moves the focus to an item of sub-content to be deleted on the second shortcut list, for example, "music 1" by manipulating the control device 100, and the user selects the sub-content to be deleted, "music 1", by pressing the "ok" key on the control device 100. The user moves the focus to a function key, for example, a "delete (Delay)" key on the second shortcut list by manipulating the control apparatus 100, and transmits a first instruction, which instructs to delete the sub-content "music 1" to be deleted from the second shortcut list, to the display device 200 by pressing a "confirm" key on the control apparatus 100. The display apparatus 200 deletes "music 1" from the second shortcut list in response to the first instruction, and at this time, the second shortcut list includes "music 3", that is, "music 3" is all the sub-content to be presented. The user moves the focus to a function key on the second shortcut list, for example, a "play" key, by manipulating the control device 100, so as to send a second instruction to the display apparatus 200, instructing to display all the sub-content to be displayed, i.e., playing "music 3". In the above, the first instruction and the second instruction jointly constitute a first editing instruction.

In some embodiments, as shown in fig. 18 (r), the user moves the focus to a function key on the second shortcut list, for example, an "Add (Add)" key by manipulating the control apparatus 100, and presses an "ok" key on the control apparatus 100 to send a third instruction to the display device 200, where the third instruction is used to instruct to display an optional list, where the optional list includes all sub-contents in the first external device, and where the sub-contents to be presented, which are already located in the second shortcut list, can be identified in all sub-contents. The selectable list and the second shortcut list may be displayed on different layers, or may be displayed on different layers, but the selectable list and the first user interface are displayed on different layers. As shown in fig. 18, taking the selectable list and the second shortcut list shown in the same layer as an example, at this time, only the selectable list is displayed, and the second shortcut list is deleted and displayed, where the selectable list includes all sub-contents "music 1", "music 2", and "music 3", where the second shortcut list includes "music 1" and "music 3", and the options of "music 1" and "music 3" in the selectable list may be grayed out to prompt the user that the two items are already located in the second shortcut list. The user moves the focus to the sub-content to be added in the selectable list, for example, "music 2", by manipulating the control device 100, and by pressing the "confirm" key on the control device 100, sends a fourth instruction to the display apparatus 200, the fourth instruction is used to instruct to add and display the item of the sub-content to be added in the second shortcut list, the display apparatus 200 deletes and displays the selectable list in response to the fourth instruction, and displays the second shortcut list again as shown in fig. 18, at this time, the second shortcut list is an edited second shortcut list, i.e., includes "music 2" and at this time, all the sub-content to be displayed includes "music 1", "music 2" and "music 3". The user moves the focus to a function key on the second shortcut list, for example, a "play" key, by manipulating the control device 100, so as to send a fifth instruction to the display apparatus 200, instructing to display all the sub-contents to be displayed, i.e., playing "music 1", "music 2", and "music 3". In the above, the third instruction, the fourth instruction and the fifth instruction together form the first editing instruction.

And S1604, responding to the first editing instruction, and displaying a third user interface, wherein the third user interface corresponds to the main content and the target sub-content.

The display apparatus 200 responds to the first editing instruction to display the target sub-contents, i.e., "music 2" as the target sub-contents in the flow shown by (r) to (r) in fig. 17, i.e., "music 1" and "music 3" as the target sub-contents in the flow shown by (r) to (c) in fig. 17, and "music 1", "music 2" and "music 3" as the target sub-contents in the flow shown by fig. 18.

In some embodiments, if either of the main content and the target sub-content is non-screen content, the third user interface corresponds to a user interface having screen content in the main content and the target sub-content, and the third user interface further includes overview information of the non-screen content. For example, in the flow shown in (r) to (r) in fig. 17, if the main content is "picture a", the displayed content is displayed, the target sub-content is "music 2", and the non-displayed content is displayed, the third user interface includes overview information of "picture a" and "music 2", for example, "currently playing: music 2 ". For another example, in the flow shown in fig. 17, in the processes from (v) to (v), the main content is "picture a", which is a picture content, the target sub-contents are "music 1" and "music 3", which are both non-picture contents, and the third user interface is shown in fig. 17 as (v), which includes "picture a", and the overview information of "music 1" and "music 3", such as "playing: music 1, next: music 3 ". For another example, if the main content is music and the main content is non-frame content, the first user interface corresponds to the main desktop of the display device 200, and the target sub-content is a picture, the third user interface includes the picture and the overview information corresponding to the main content music.

In some embodiments, if the main content and the target sub-content both have screen content, the third user interface displays screens corresponding to the main content and the target sub-content at the same time, wherein the screens of the main content and the target sub-content may be displayed in a certain ratio or partially overlapped.

In embodiment 2, the display device 200 may directly display the second shortcut list on the current user interface in response to the second control instruction sent by the user, and further respond to the first editing instruction sent by the user based on the second shortcut list to simultaneously display other contents in the current external device.
