Referring to fig. 4, in some embodiments, the system is divided into four layers, which are, from top to bottom, an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer.

In some embodiments, at least one application program runs in the application program layer, and the application programs may be windows (windows) programs carried by an operating system, system setting programs, clock programs or the like; or an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an Application Programming Interface (API) and a Programming framework for the Application. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display driver, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (like fingerprint sensor, temperature sensor, pressure sensor etc.) and power drive etc..

In some embodiments, a smart device, which is the same as or similar to the display device 200, may be used with the control apparatus 100, and the control apparatus 100 has at least one physical key, and a user may click the corresponding key as required to send a control command to the display device 200. For example, if the user desires to switch to the next channel, the "channel +" button on the control device 100 may be clicked; for another example, if the user clicks the "live" button, the display device is controlled to jump to the signal source associated with the "live" button.

In some embodiments, control device 100 includes, but is not limited to, a remote control, a keyboard, a remote control handle, and the like.

In some embodiments, in response to a certain key being triggered, the control apparatus 100 generates a control instruction, where the control instruction includes a key value of the key, where the key value corresponds to an identification of the key, and then sends the control instruction to the display device 200; the display device 200 recognizes key values in the control instruction in response to the control instruction, distributes the key values to corresponding function modules, and executes corresponding logic programs by the function modules.

In some embodiments, the functionality of some keys of the control device 100 are fixed, such as channel +, channel-, volume +, volume-, etc., and do not support user editing or modification of such key functionality. Some keys of the control device 100 support associated binding, editing and modifying of functions, for example, support a user to bind signal source types associated with the "live broadcast" key, so that the user can quickly switch to a corresponding signal source by one key when triggering the "live broadcast" key.

In some embodiments, taking the control apparatus 100 as a remote controller as an example, a user needs to open a remote controller setting page according to an operation path of "system setting-remote controller setting" in advance, as shown in fig. 5 as an example, the remote controller setting page may include a setting control 51 of a target key, and the user sets an association relationship between the target key and a signal source through the setting control 51, where the signal source includes, but is not limited to, a television signal source, a media interface type signal source, and the like.

In some embodiments, referring to fig. 5, the TV signal source may include ATV (Analog TV) and DTV (Digital TV), and the DTV signal source includes, but is not limited to, DVBC (Digital Video Broadcasting), DTMB (Digital Television Terrestrial Multimedia Broadcasting), and other types.

In some embodiments, referring to fig. 5, the media Interface type signal source includes, but is not limited to, HDMI (High Definition Multimedia Interface), VGA (Video Graphics Array) Interface, AV Interface (also called audio Video input Interface), DVI (Digital Video Interface), and the like.

In some embodiments, referring to fig. 5, if the user selects the signal source type associated with the target key as DVBC by setting the control 51, and then clicks the confirmation setting control 52, the display device stores the association relationship between the target key and the DVBC, and then the user triggers the target key on the remote controller, and the controller queries that the target key is currently associated with the DVBC, and then automatically jumps to the play interface of the DVBC signal source. If the user clicks the cancel setting control 53, the set target key is cancelled, and when the subsequent user triggers the target key on the remote controller, the controller queries the signal source which is not associated with the target key, and does not respond to the control instruction sent by the remote controller, and the currently displayed signal source is kept unchanged, i.e. the process of switching the signal source by one key is not executed.

In some embodiments, after a user triggers a target key on a remote controller, the remote controller generates and sends a control instruction to a display device, a controller responds to the control instruction, and inquires that a signal source type currently associated with the target key is DVBC, the controller further detects a signal access state of the DVBC, if the DVBC has no media information signal access, the controller cannot jump to a DVBC signal source, at this time, the target key is equivalent to a temporary failure, the user can only wait for the signal access of the DVBC, or the signal source type associated with the target key is modified in a page of fig. 5, so that the target key is triggered to switch to other available signal sources except the DVBC, and inconvenience is brought to the user.

In order to solve the above problem, in some embodiments, when a user triggers a target key on the control device, the control device generates and sends a control instruction to the display device, where the control instruction includes a key value of the target key; and the controller of the display equipment receives the control instruction, identifies the key values in the control instruction, detects whether the target key is triggered or not if the target key has the associated preset signal source, and directly switches to the currently associated signal source if the target key has the associated preset signal source without performing matching on the associated signal source of the target key.

In some embodiments, if it is detected that the target key does not have an associated preset signal source, that is, the user does not perform signal source association binding on the target key before, the target key may be matched and switched to the target signal source according to a preset matching rule based on the signal source categories supported by the display device and the signal access state of each signal source category, and the association relationship between the target key and the target signal source is stored. The configuration of the preset matching rule and the implementation of the matching target signal source will be described in detail below.

In some embodiments, the display device may configure the matching priority of the signal source, for example, the priority is that the television signal source > the media interface type signal source, that is, the target signal source is preferentially matched from the television signal source, and if the target signal source is not matched from the television signal source, the target signal source is matched from the media interface type signal source.

In some embodiments, the controller queries N types of tv signal sources that the display device supports receiving, if the display device supports receiving only one type of tv signal source a, i.e. N is 1, detects whether the tv signal source a has completed channel searching (i.e. searching channels), and if the tv signal source a has not completed channel searching, matches the target signal source from the media interface type signal source. If the television signal source a finishes channel searching, further detecting whether the television signal source a has media information signal access at present; if the television signal source a does not have the media resource signal access at present, the television signal source a is matched with the target signal source from the media interface type signal source; and if the television signal source a has the media information signal access currently, matching the television signal source a as a target signal source.

In some embodiments, if the display device supports receiving multiple television signal sources, that is, N is greater than 1, then M first signal sources are screened from the N television signal sources, where the first signal sources are signal sources that have completed channel search and currently have media information signal access, and M is greater than or equal to 0 and less than or equal to N, and then a target signal source is matched from the M first signal sources.

In some embodiments, if the first signal source has only one television signal source b, i.e., M is 1, the television signal source b is directly matched as the target signal source.

In some embodiments, if the number M of the first signal sources is greater than 1, for example, the first signal sources include an ATV, a DVBC, and a DTMB, the signal source with the highest priority may be automatically matched as the target signal source based on a preset priority, for example, the preset priority is DVBC > DTMB > ATV, and then the DVBC is matched as the target signal source.

In the foregoing embodiment, N television signal sources are traversed, then M first signal sources are screened out from the N television signal sources, and then a target signal source is matched according to the number of the first signal sources and a preset priority. In other embodiments, whether the tv signal sources have completed channel searching and currently have media signal access may be sequentially detected according to the priority order of the N tv signal sources. Taking a television signal source comprising an ATV, a DVBC and a DTMB as an example, assuming that the preset priority is DVBC > DTMB > ATV, preferentially detecting the DVBC, and if detecting that the DVBC does not perform channel searching, continuously detecting the DTMB; if detecting that the DVBC has finished searching channels, further detecting whether the DVBC has signal access currently, if the DVBC has no media resource signal access currently, namely the DVBC signal source is unavailable, continuing to detect the DTMB, and if the DVBC has the media resource signal access currently, namely the DVBC signal source is available, stopping the matching process and matching the DVBC as the target signal source. The embodiment may not need to traverse all the N television signal sources, but immediately terminate the matching process when the target signal source is matched, thereby improving the matching efficiency of the target signal source.

In some embodiments, when the target signal source is matched according to the above embodiments, a target key association setting page as illustrated in fig. 6 may be displayed before switching to the target signal source. The target key association setting page includes third prompt information 61, a switching control 62 and a third confirmation control 63, where the third prompt information 61 is used to prompt that the target key is associated with the target signal source, for example, in fig. 6, the third prompt information 61 indicates that "the target key is bound, and digital video broadcasting can be quickly entered when the target key is pressed in any scene".

In some embodiments, the third confirmation control 63 is, for example, presented as "i know", the first time 631 is synchronously displayed at the third confirmation control 63, when the target key association setting page starts to be displayed, the first time 631 is equal to a preset time (for example, 30s), and counting down from the preset time, if the user actively clicks the third confirmation control 63, or the controller detects that the user does not perform any operation all the time when the first time 631 changes to 0, the association binding of the target key this time is defaulted, the target key association setting page is automatically closed, the target signal source DVBC is displayed, and the association relationship between the target key and the DVBC is stored.

In some embodiments, if the user clicks the switching control 62, the user interface is controlled to jump to the remote control setting page illustrated in fig. 5, and the user may set the signal source type associated with the target key on the remote control setting page according to the key requirement.

In some embodiments, referring to fig. 6, an operation guidance image may be further displayed in the target key association setting page, where the operation guidance image includes an operation object diagram 64 and a signal source identifier 65 bound to the operation object diagram 64, the operation object diagram 64 includes an image of the control device and an enlarged view of the target key, and the signal source identifier 65 may include an identifier diagram of the target signal source and/or a signal source name, where the signal source name is, for example, a full name, an abbreviation, an english abbreviation, or the like of the signal source. And the user checks the operation guide image, and knows that the target key on the control device is pressed, so that the signal source related to the target key can be quickly switched by one key. The identification of signal sources in this application is merely exemplary and does not constitute a limitation on the identification of the signal sources of the actual product.

In some embodiments, if the number M of the first signal sources is greater than 1, a first hint page may also be displayed on the user interface. The first reminder page, as exemplified in fig. 7, includes first reminder information 71, identifications of the M first signal sources, a first confirmation control 72, and a first cancellation control 73. The first prompt message 71 is used to prompt the user to select a target signal source, for example, in fig. 7, the first prompt message 71 is presented as "please select a signal source associated with a target key, and pressing the target key in any scene can quickly enter the selected signal source".

In some embodiments, referring to fig. 7, the identifier of the M first signal sources may include a signal source identifier map and/or a signal source name, each first signal source corresponds to one selection control 74, at most only one of the M selection controls can be selected, for example, fig. 7 includes DVBC, DTMB and ATV, the user clicks the selection control corresponding to the ATV (analog television), so that the ATV is selected, and then triggers the first confirmation control 72, so that the controller matches the ATV as a target signal source, closes the first prompt page, switches to the ATV signal source, and stores an association relationship between a target button and the ATV.

In some embodiments, no matter whether the user selects the target signal source in the first prompt page, if the user finally triggers the first cancel control 73, the setting of the associated signal source for the target key is cancelled, the current associated binding process of the target key is exited, and the current user interface is returned.

In some embodiments, FIG. 8 illustrates another first hint page that includes first hint information 71 and the identification of M first signal sources. In this embodiment, a user may press a direction key on the control device according to the arrangement of the M signal source identifiers, so as to move a focus position of the mobile control device, for example, in the example in fig. 8, three signal source identifiers are arranged in a row, the user may operate left and right keys on the control device, so that a focus is dropped on a target signal source that is expected to be associated and bound, for example, the user adjusts the focus to the DTMB, and then triggers a confirmation key (OK key) on the control device, so that the controller matches the DTMB with the target signal source, closes the first prompt page, and switches to the DTMB signal source, and simultaneously stores an association relationship between the target key and the DTMB.

In some embodiments, based on the first prompt page illustrated in fig. 8, if the user triggers a return key on the remote controller, the signal source that is associated with the target key is cancelled, the association binding process of the target key is exited, and the current user interface is returned. Fig. 8 is a more concise first prompt page than fig. 7, and the related function setting is realized by means of keys such as a direction key, an OK key, and a return key on the control device. The user confirms the selected target signal source in the first prompt page, and after the first prompt page is closed, since the user knows that the associated signal source set for the target key is the selected signal source and the target signal source is set by the user according to personal preference, the target key association setting page illustrated in fig. 6 does not need to be displayed, and the target signal source is switched to be displayed.

In some embodiments, if no first signal source is screened from the N television signal sources, that is, M is equal to 0, then the target signal source is further matched from the media interface type signal sources, the controller queries P second signal sources that the display device supports receiving, where the second signal sources may correspond to media interface channels, such as HDMI interfaces, AV interfaces, DVI interfaces, and the like, and screens Q third signal sources currently having media information signal access from the P second signal sources, where Q is greater than or equal to 0 and less than or equal to P, and then matches the target signal source from the Q third signal sources.

In some embodiments, if the third signal source has only one media interface type signal source a, i.e. Q ═ 1, then the media interface type signal source a is directly matched as the target signal source.

In some embodiments, if the number Q of the third signal sources is greater than 1, for example, the third signal sources are DVI, HDMI1 and HDMI2, the signal source with the highest priority among the third signal sources may be automatically matched as the target signal source based on the preset priority, for example, the preset priority is HDMI1 > HDMI2 > AV > DVI, and HDMI1 is automatically matched as the target signal source.

In the foregoing embodiment, P second signal sources (i.e., media interface type signal sources) are traversed, Q third signal sources are screened from the P second signal sources, and then a target signal source is matched according to the number of the third signal sources and a preset priority. In other embodiments, whether the P second signal sources currently have media information signal access may be sequentially detected according to the priority order of the P second signal sources. Taking the second signal source comprising AV, DVI, HDMI1 and HDMI2 as an example, assuming that the preset priority is HDMI1 > HDMI2 > AV > DVI, preferentially detecting HDMI1, and if detecting that no media signal is currently accessed in HDMI1, continuing to detect HDMI 2; and if the HDMI1 is detected to have the media resource signal access currently, stopping the matching process, and matching the HDMI1 as a target signal source. The embodiment may not need to traverse all P second signal sources, but immediately terminate the matching process when the target signal source is matched, thereby improving the matching efficiency of the target signal source.

In some embodiments, if Q is 1, or Q is greater than 1 and matches the target signal source according to the priority, when the target signal source matching is completed, a target key association setting page as illustrated in fig. 6 may be displayed to prompt the user that the target key is associated with the target signal source, and the user may confirm the association relationship, or switch the signal source associated with the target key.

In some embodiments, if the number Q of the third signal sources is greater than 1, a second hint page may also be displayed on the user interface. The second prompt page as exemplified in fig. 9 includes second prompt information 91, the identifications of Q third signal sources, a second confirmation control 92, and a second cancellation control 93. The second prompt message 91 is used to prompt the user to select a target signal source, for example, in fig. 9, the second prompt message 91 is presented as "please select a signal source channel associated with a target key, and pressing the target key in any scene can quickly enter the selected signal source".

In some embodiments, referring to fig. 9, the identifier of the Q third signal sources may include a signal source identifier diagram and/or a signal source name, each third signal source corresponds to one selection control 94, and only one of the Q selection controls can be selected, for example, fig. 9 includes HDMI1, HDMI2, AV, and VGA, and the user clicks the selection control corresponding to the AV to select the AV, and then triggers the second confirmation control 92, so that the controller matches the AV with the target signal source, closes the second prompt page, and switches to the AV signal source, and stores the association relationship between the target button and the AV signal source.

In some embodiments, no matter whether the user selects the target signal source in the second prompt page, if the user finally triggers the second cancel control 93, the setting of the associated signal source for the target key is cancelled, the current associated binding process of the target key is exited, and the current user interface is returned.

In some embodiments, fig. 10 illustrates another second hint page that includes second hint information 91 and the identification of Q third signal sources. In this embodiment, the user may press a direction key on the control device according to the arrangement of Q third signal source identifiers, so as to move the focal position of the mobile control device, for example, in the example of fig. 10, four signal source identifiers are arranged in an array of two rows and two columns, the user may operate an up key and a down key on the control device to change the rows, operate a left key and a right key on the control device in each row, so that the focal point jumps to a target signal source to which association binding is desired, for example, the user turns the focal point to HDMI2, and then triggers an OK key on the control device, then the controller matches HDMI2 as the target signal source, closes the second prompt page, and switches to the HDMI2 signal source, and simultaneously stores the association relationship between the target key and HDMI 2. The focus in fig. 10 and 8 is not limited to the highlighted form such as applying a focus frame, highlighting, and marking a signal source where the focus is enlarged, as long as it is ensured that the user can accurately distinguish the focus position.

In some embodiments, based on the second prompt page illustrated in fig. 10, if the user triggers the return key on the remote controller, the signal source for setting the association for the target key is cancelled, the association binding process of the target key is exited, and the current user interface is returned. Fig. 10 is a more simplified second prompt page compared to fig. 9, and the related function setting is realized by means of keys such as a direction key, an OK key, and a return key on the control device. The user confirms the selected target signal source in the second prompt page, and after the second prompt page is closed, since the user knows that the associated signal source set for the target key is the selected signal source and the target signal source is set by the user according to personal preference, the target key association setting page illustrated in fig. 6 does not need to be displayed, and the target signal source is switched to be displayed.

In some embodiments, referring to the second remote controller setting page illustrated in fig. 11, after the user clicks the setting control 51, the remote controller setting page displays the signal source list 111, the signal source list 111 includes signal source identifiers of a television signal source and a media interface type signal source supported by the display device, each signal source identifier corresponds to one selection control 111A and one upper control 111B, the user can select a signal source associated with a desired target key through the selection control 111A, and the upper control 111B is used to adjust the priority ranking of each signal source in the signal source list.

In some embodiments, the upper control 111B may be configured to be triggered to adjust the signal source up by one rank, for example, when the user triggers the upper control 111B corresponding to HDMI2, the priority of HDMI2 and HDMI1 are interchanged, that is, HDMI2 is raised to the previous rank of HDMI1, and HDMI is lowered by one rank, and the user operates the upper control 111B to sort the signal sources in the signal source list, that is, the signal source list may also be used to represent the priority order when performing signal source association matching on the target key, for example, from top to bottom in the signal source list of fig. 11.

In some embodiments, the upper control 111B may be configured to be triggered to set the signal source to the top, e.g., the user triggers the upper control 111B corresponding to HDMI1 to raise HDMI1 to the first ordinal, and to lower the other signal sources by one ordinal. It should be noted that the setting manner of the signal source priority is not limited to the example in fig. 11, and in other implementations, for example, the upper control 111B may be adjusted to be a lower control, or a user is supported to manually drag the signal source to a specified sequence, and the like.

In some embodiments, if the user does not select the signal source associated with the target key (i.e., blank selection) in the remote controller setting page illustrated in fig. 11, and then clicks the confirmation setting control 52, the priority of the signal source is generated and saved according to the current sorting of the signal source list 111; if the user sets the associated signal source for the target key and then clicks the confirmation setting control 52, storing the association relationship between the target key and the selected signal source and storing the priority of the signal source; if the user clicks the cancel setting control 53, the priority of the signal source is not saved, and the signal source associated with the target key is cancelled.

In some embodiments, based on the priority preset by the user in the remote controller setting page of fig. 11, whether each signal source is the target signal source may be sequentially detected in the priority order until the target signal source is matched.

In the previous embodiment, it was illustrated that the destination signal source was matched preferentially from the television signal source, and secondarily from the media interface type signal source. By using the priority setting mode of fig. 11, signal source cross detection of different categories and systems is supported, for example, the signal source priority preset by a user is DVBC > HDMI1 > DTMB > HDMI2 > ATV > AV > DVI, the DVBC is used as a matching starting point to preferentially detect whether the DVBC has finished channel searching, if the DVBC has not finished channel searching, whether the HDMI1 has media resource signal access at present is continuously detected, if the HDMI1 has no media resource signal access at present, the DTMB is continuously detected, and so on until a target signal source is matched; if the HDMI1 has the media asset signal access currently, the matching process is stopped, and the HDMI1 is matched as a target signal source.

In some embodiments, if detecting that the DVBC has completed channel search, further detecting whether the DVBC currently has media asset signal access, and if the DVBC currently has media asset signal access, stopping the matching process and matching the DVBC as a target signal source; if the DVBC has no media resource signal access at present, whether the HDMI1 has the media resource signal access at present is continuously detected, and the rest is done in sequence until the target signal source is matched.

In some embodiments, after the user presses the target key, if the current state of the display device is that the television signal source does not search for a channel or has no media resource signal access, the media interface type signal source also has no media resource signal access, that is, is not matched with the target signal source, at this time, the associated signal source cannot be set for the target key, and the user cannot jump to any signal source, a third prompt page as illustrated in fig. 12 may be displayed on the user interface, where the third prompt page is used to prompt that "there is no currently available signal source, the target key fails to be bound, and please check the signal source connection". After the user views the third prompt page, the user can check the working state of the signal source interface connection or the signal receiving device (such as a set top box, an antenna and the like) to enable the signal source to access the signal, then press the target key on the control device again, and the control device responds to the triggering of the target key to generate and send a control instruction to the display equipment; and the display equipment responds to the control instruction, identifies the key value of the target key and executes the process of matching the target signal source again.

In some embodiments, if the controller does not match the target signal source, K fourth signal sources are screened out from N television signal sources, where K is greater than or equal to 0 and is less than or equal to N, the fourth signal source is a signal source that has currently access to a media asset signal but has not completed channel search, and then, according to the K fourth signal sources, a first channel search page is generated and controlled by a display to display, as shown in fig. 13, where the channel search page includes channel search prompt information 131, channel search indication information 132, and channel search control 133.

In some embodiments, referring to fig. 13, the channel searching prompt message 131 is used to prompt that a signal line or an antenna should be kept in a connection state during channel searching, so as to ensure effective channel searching; if the user presses a return key on the control device, closing the channel searching page and returning to the current user interface; if the user clicks the channel searching control 133, the channel searching program is started; the channel searching indication information 132 is used for displaying names of the K fourth signal sources and the searched number of channels corresponding to each fourth signal source. The K fourth signal sources in the channel searching instruction information 132 may be sorted according to the signal source priorities.

In some embodiments, for a scene where K is greater than 1, the channel search may be sequentially performed on K fourth signal sources in sequence according to the signal source priorities, for example, in the example of fig. 13, the channel search indication information 132 includes DTMB (digital television terrestrial multimedia broadcasting) and ATV (analog television), and if the DTMB priority is higher than the ATV, the channel search is preferentially performed on the DTMB signal source and the channel searched number corresponding to the DTMB is synchronously updated, and after the channel search is completed on the DTMB signal source, the channel search is continued on the ATV and the channel searched number corresponding to the ATV is synchronously updated until the channel search is completed on the ATV.

In some embodiments, the channel searching may also be performed on the K fourth signal sources at the same time, and the number of channels searched by the K fourth signal sources is updated until the channel searching is completed for all the K fourth signal sources.

In some embodiments, when the controller detects that the channel searching of all K fourth signal sources is finished, the controller controls the display to display a fourth prompting page as illustrated in fig. 14, where the fourth prompting page displays the fourth prompting information 141, the identifications of the K fourth signal sources, the fourth confirmation control 142, and the fourth cancellation control 143. The fourth prompting information 141 is used for prompting that the channel search is finished and please select a signal source associated with the target key; the user selects a target signal source in the fourth prompt page and clicks the fourth confirmation control 142, then the controller closes the fourth prompt page, jumps to the display interface of the target signal source, and stores the association relationship between the target key and the target signal source; if the user clicks the fourth cancel control 143, the signal source associated with the target key is cancelled, and the current user interface is returned without switching the signal source.

In some embodiments, if the controller does not match the target signal source, K fourth signal sources are screened out from the N television signal sources, and then a second channel search page is generated and controlled by the display according to the K fourth signal sources, as shown in fig. 15, fifth prompt information 151, names of the K fourth signal sources, and a channel search control 133 are displayed in the channel search page. The fifth prompt message 151 is used to prompt "please select a signal source and start channel searching, and after channel searching is finished, the target key and the selected signal source are bound automatically"; for a scene with K greater than 1, a channel search selection control 152 is corresponding to the name of each fourth signal source, and at most only one of the K channel search selection controls 152 can be selected, referring to fig. 15, for example, when a user clicks the channel search selection control 152 corresponding to an ATV (analog television), so as to switch the channel search selection control 152 corresponding to the ATV to a selected state, and then the user clicks the channel search control 133, a channel search page may be presented as a change in the example in fig. 16, the names of other K-1 fourth signal sources that are not selected by the user and the corresponding channel search selection controls 152 are cancelled, only the names of the selected ATV signal sources are kept to be displayed, the number of searched channels corresponding to the ATV signal sources is updated synchronously, and channel search state prompt information 161 is displayed as "searching in progress".

In some embodiments, when the channel search page illustrated in fig. 16 is displayed, the controller detects a channel search process of the ATV as a target signal source, and if it is detected that the channel search of the ATV is finished, automatically stores an association relationship between a target key and the ATV signal source, and makes the channel search page to present the change illustrated in fig. 17, changes the channel search status prompt information 161 to "channel search completed" or "channel search finished", and displays prompt information such as "the target key is bound and the channel can be quickly entered into the analog television by pressing the target key" on the page. The controller may close the channel search page when detecting that the display of the channel search page of fig. 17 has reached a preset duration (e.g., 10 seconds), and control the display to jump to the display interface of the ATV, so as to implement automatic matching and association of the target signal source after the channel search is finished, and automatically switch to the target signal source.

In some embodiments, for a scenario where K ═ 1, that is, a query is made that there is currently only one fourth signal source, a channel search page similar to the example of fig. 16 and 17 may be referenced, a channel search is made for only one fourth signal source, and at the end of the channel search, only one available fourth signal source is matched as a target signal source, and a jump is automatically made to the target signal source.

In some embodiments, for a scenario where K is greater than 1, referring to a channel search page like the example of fig. 16 and 17, a channel search may be performed only on the fourth signal source with the highest priority, and at the end of the channel search, the fourth signal source with the highest priority is matched as a target signal source, and a jump is automatically made to the target signal source. For example, the fourth signal source includes a DTMB and an ATV, and since the priority of the DTMB is higher than that of the ATV, the channel searching is performed only on the DTMB, but not on the ATV, and after the channel searching is finished, the controller stores the association relationship between the target key and the DTMB, and controls the display to display the video signal of the DTMB.

In some embodiments, the controller responds to a control instruction sent by the control device, reads a key value contained in the control instruction, identifies that the key value corresponds to a target key, further detects whether the signal source a has media information signal access currently if the target key is detected to have the signal source a associated currently, and can directly switch to the signal source a if the signal source a has the media information signal access currently.

In some embodiments, if the signal source a does not have a media resource signal currently accessed, a fifth prompt page as illustrated in fig. 18 may be displayed, in which a sixth prompt message 181, a unbinding and switching 182, and a fifth cancel control 183 are displayed. Wherein, the sixth prompt message 181 is used to prompt "is the signal source a without a signal, whether to release the binding between the target key and the signal source a, and switch to another available signal source? "; if the user clicks the unbinding and switching 182 after viewing the sixth prompt message 181, deleting the currently stored association relationship between the target key and the signal source a, thereby unbinding the target key and the signal source a, executing the matching process for the target signal source according to the scheme of the above embodiment, assuming that the matched target signal source is the signal source b, storing the association relationship between the target key and the signal source b, thereby constructing a new bind for the target key, and switching to display the video signal of the signal source b.

In some embodiments, if the user clicks the fifth cancel control 183 after viewing the sixth prompt message 181, the fifth prompt page is closed, and the association relationship between the target key and the signal source a is kept unchanged, but the signal source a cannot be switched to. For example, the display device is currently playing the signal source d, in this scenario, the user presses the target key, the controller detects that the target key is associated with the signal source a, but the signal source a is not currently accessed by a media resource signal, and then the user clicks the fifth cancel control 183 in the fifth prompt page, and returns to the display interface of the signal source d, and then the user may check the connection of the signal source a, and trigger the target key on the control device again, and retry the one-key switching to the signal source a.

In some embodiments, fig. 19 illustrates an underlying architecture diagram for responding to a target key control command, and the display device side includes a control command receiving module 221, a command processing module 251, a signal source switching module 261, and a storage module 281. The control instruction receiving module 221 is configured to receive a control instruction sent by the control device, and distribute a key value included in the control instruction to the instruction processing module 251; the instruction processing module 251 is used for triggering and executing relevant logic according to key values of the keys; the storage module 281 may store a Setting database, where the Setting database is used to store data related to system settings, including an association relationship between a target key and a signal source, where the signal source may be identified and stored in a string form, such as DVBC, ATV, or HDMI 1; the signal source switching module 261 is connected to the display, and is configured to drive the display to switch and display the signal source.

In some embodiments, the instruction processing module 251 receives a key value of a key, if the key value is identified to correspond to a target key, the storage module 281 is accessed to query whether the target key has an associated preset signal source, and if the target key has an associated signal source a, the instruction processing module 251 controls the signal source switching module 261 to switch to the signal source a; if the target key does not have the associated preset signal source, the instruction processing module 251 matches the target signal source according to the scheme of the above embodiment, and if the matched target signal source is the signal source c, on one hand, the instruction processing module 251 stores the association relationship between the target key and the signal source c in the Setting database of the storage module 281 to realize warehousing of the target key Setting data, and on the other hand, the instruction processing module 251 controls the signal source switching module 261 to switch to the signal source c.

In some embodiments, the Setting database in the storage module 281 is further configured to store signal source priorities preset by a user, and after the user edits and modifies the signal source priorities, the storage module 281 needs to update the signal source priorities synchronously. The instruction processing module 251 is further configured to obtain the signal source priority from the storage module 281, and further match the target signal source for the target key according to the signal source priority and a preset matching rule. The underlying architecture diagram in response to the target key control command is not limited to the example of fig. 19.

In some embodiments, fig. 20 illustrates a third remote controller setting page, where the remote controller setting page further includes a switch control 201, and the switch control 201 is configured to turn on or off a signal source binding function of the target key. If the switch control 201 is in the off state, the remote controller sets the page not to display the signal source list, and the user clicks the target key on the remote controller, the display device does not respond to the corresponding control instruction, i.e. the signal source is not switched, and the logic of target key binding state detection and target signal source matching is not executed; if the user switches the switch control 201 to the on state, referring to fig. 20, a signal source list is displayed on a remote control setting page, so that the user selects a signal source type associated with the target key and sets a signal source priority.

In the foregoing embodiment, the configuration of the preset matching rule and how to match the target signal source by using the rule have been described in detail, and therefore, the specific implementation manner of step S214 may refer to the foregoing embodiment, which is not described herein again. According to the method and the device, when a user presses a target key on the control device, a signal source association binding mechanism of the target key can be rapidly triggered and the signal source automatically skips in a scene that the target key is not bound with a signal source, so that the rapid response of one-key signal source switching function is improved, the signal source associated with the key can be rapidly and conveniently bound, the usability of the target key is ensured, and the user operation experience is improved.

The preset matching rule is not limited to the embodiment of the present application, but may be adaptively adjusted and extended based on factors such as the capability of the display device to support the access signal source, the attribute and state of each signal source, and the user usage preference, for example, the display device may perform configuration update on the preset matching rule when performing system upgrade.
