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 resource in the system and obtain the service 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.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) that a user acts on a display screen, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in detail below with reference to the accompanying drawings and specific embodiments.

The following describes a video playing method provided in the embodiment of the present application:

referring to fig. 6, a flow diagram of a video screen projection method according to some embodiments is illustrated in fig. 6. The execution subject of the flow shown in fig. 6 may be the display device described above.

As shown in fig. 6, the process may include the following steps:

step 101, responding to a network awakening packet carrying application information sent by a mobile terminal, and starting the display device.

In this embodiment, the network wake-up packet is a wake-up packet for waking up the display device through the network. This network may be a local area network or a wide area network. As to the technical means adopted by the network wake-up packet to wake up the display device to start up, the determination may be made according to the actual conditions of the network where the mobile terminal and the display device are located, and the embodiment of the present application is not limited thereto.

For example, if the mobile terminal and the display device interact with each other under a lan, the wake-on-lan packet may be a specific data packet sent by the mobile terminal, and the specific data packet is also referred to as a "magic data packet".

If the mobile terminal and the display device interact with each other in the wan, the network wake-up packet generally uses a remote magic packet for implementing remote wake-up.

It should be noted that, the technical solution of the present application is directed to a case where the display device is not in operation, and if the display device is in operation, that is, in a running state, there is no problem that the video screen projection is slow due to time consumption when the mobile terminal establishes a connection with the display device.

In addition, the display device is not operated, and the CPU of the display device is not operated.

For example, if the Windows system is installed in the display device, the display device is not in operation, including: sleep, hibernate, and power off.

If the Linux system is installed in the display device, the display device is in a non-working state, including: shutdown, Suspend to RAM (Suspend to memory), Suspend to Disk (Suspend to hard Disk).

In an embodiment, based on the situation that the display device is turned off, first, the mobile terminal already obtains information of the display device existing in the network, and after determining the information of the display device to be screen-projected, the user projects a screen to the display device, that is, when establishing a connection with a television, if the display device does not respond, the mobile terminal continuously broadcasts a magic packet containing a MAC address of the display device to turn on the display device until the display device starts to respond to a connection request sent by the mobile terminal.

And step 102, after the display equipment is started, establishing connection with the mobile terminal, and simultaneously analyzing the application information.

In this embodiment, the display device establishes a connection with the mobile terminal, and performs synchronization with the analysis of the application information to compress the time of the screen projection process.

The above-mentioned embodiments of establishing connection with the Mobile terminal include at least five types, which are a USB (Universal Serial Bus) connection mode, an HDMI (High-Density multi-chip Interconnect) connection mode, an MHL (Mobile High-Definition Link) connection mode, a DIAL connection mode, and a multi-screen interaction. The USB connection mode, the HDMI connection mode and the MHL connection mode all need data lines to be connected, and for projecting a screen to display equipment, the connection mode needs to be manually connected with the display equipment through lines, so that the operation is complex. And the DIAL connection mode and multi-screen interaction do not need data line connection. The DIAL can perform bidirectional operation among devices, and multi-screen interaction can perform bidirectional operation among devices, and can also perform bidirectional operation among large screens and small screens. As to what connection method is selected in the present embodiment, the connection method can be determined according to actual situations, and the present embodiment is not limited thereto.

In this embodiment, the establishing of the connection with the mobile terminal includes connecting to the network, that is, establishing the connection with the mobile terminal in a case where the network connection is successful.

In addition, the embodiment needs to parse the application information to determine the subsequent steps to be executed according to the information included in the application information.

The application information can enable the display device to realize the functions of the custom information through the custom information.

In one embodiment, the wake-on-lan packet is a magic packet, and as shown in fig. 7, the original magic packet generally contains 6 consecutive 0XFF bytes and a MAC address repeated 16 times. The embodiment of the application adds information related to an application program for sending the magic packet to an original magic packet format. As the application information of the extended magic packet in fig. 7, at least two pieces of information are added to the extended magic packet, and the two pieces of information are respectively the "identification information of the application" and the "indication information" in fig. 7.

The identification information of the application is used for identifying the application of which mobile terminal the wake-on-lan packet originates from, so that the display device determines which application is started according to the identification information.

The indication information is information for indicating an operation to be executed after the display device is powered on, for example, indicating whether an application is started in a foreground or a background after the display device is powered on.

In order to facilitate the display device to read the application information, the application information may be saved after the step of starting the display device is executed.

It should be noted that the application information may include a URI (Uniform Resource Identifier) of the video, may not include a URI of the video, and whether or not the video includes the URI of the video may be determined according to a specific actual situation, and if the video includes the URI of the video, the URI of the video in the application information may be independent information included in the application information, and may also be added to a start parameter for setting an application, and what form the URI of the video is included in the application information may be determined according to an actual situation, for example, a user does not need to set the start parameter of the application, and the application of the display device is started according to a default parameter, and at this time, the URI of the video may be included in the application information.

Based on the description of the application information, it can be known that, according to the location of the URI of the video in the application information, the analysis of the application information may be to directly query whether the URI of the video exists in the application information, or to query the start parameter of the application set in the application information first, and then query the URI of the video from the start parameter of the application set.

Based on the above description of the identification information of the application, it can be known that the target application needs to be matched with the identification information of the application in the mobile terminal, otherwise, there may be a case where a video subsequently pushed by the mobile terminal cannot be played in the application.

For example, assuming that the video pushed by the mobile terminal is a video from which the Tencent video application can play, and the Aichi art application is opened by the display device, it is obvious that the Aichi art application cannot play a video matching with the Tencent video application, and based on this, the identification information of the application in the mobile terminal needs to be included in the application information so that the display device opens the application corresponding to the application.

Based on the analysis, in order to smoothly interact with the mobile terminal and bring a good experience effect to the user, the application adds the identification information of the application in the mobile terminal into the application information.

In addition, based on the description of the indication information in the application information, it can be seen that the first indication information in this step is used to instruct the display device to start the target application program in the background, and after the first indication information of the application information is read, the display device starts the target application program in the background according to the first indication information.

And 103, if the URI of the video does not exist in the application information, reading identification information of the application in the mobile terminal and first indication information for indicating to start the application program in the background from the application information, and starting and running a target application program corresponding to the identification information in the background in response to the first indication information so as to switch the target application program running in the background to the foreground to run and play the video when the video to be screened is determined to be received.

In view of that after a display device obtains the URI of the video to be played, the display device can directly play the video in the corresponding application program according to the URI of the video to be played without waiting for the information pushed by the mobile terminal, and certainly, if the video information pushed by the mobile terminal is received, it is possible to prevent the user experience from being bad due to the repeated playing of the URI of the same video by judging whether the URI of the video is consistent with the URI included in the application information, for example, the video a is already played, and the video a playing is reinitialized after the video information pushed by the mobile terminal is received, which obviously affects the viewing of the user and further affects the user experience. Therefore, the present display apparatus needs to first determine whether the URI of the video exists in the application information. For the case that the URI of the video to be projected is determined to exist in the application information, detailed description will be given later in the embodiment of the present application, and details are not repeated here. The step is only aimed at the condition that the URI of the video to be projected does not exist in the application information.

Starting and running the application in the background means that the application is started and run in the background, and neither the starting process nor the started interface of the application is displayed on the display of the display device, and the application cannot be seen by the user and is in a suspended running state. There are also applications running in the foreground as opposed to applications running in the background, where an application running in the foreground means that the interface of the application is displayed on the display of the display device and can be viewed by the user.

The target application running in the foreground is an application whose interface is displayed on the display of the display device, which is visible to the user and is running, relative to an application running in the background. Here, the application running in the foreground means an application whose interface is not displayed on the display of the display device, cannot be seen by the user, and is in a suspended running state.

Based on the above description, in this step, the target application running in the background is switched to the foreground to run and play the video, and it can be understood that the target application running in the background is activated and displayed on the display of the display device, and the user can see the interface of the target application.

In this embodiment, when it is determined that the video to be subjected to screen projection is received, the mobile terminal receives feedback information indicating that the display device and the mobile terminal are successfully connected, and sends the video to be subjected to screen projection to the display device, and the display device receives the video pushed by the mobile terminal, switches a target application program running in a background to a foreground to run, and plays the video by using the target application program, so that a user can view the video played in the target application program in a user interface of the display.

To facilitate understanding, as will be described with reference to fig. 8, an embodiment of the present display device is shown, and as can be seen from fig. 8, a controller of the display device includes a NIC network card, a main chip, a tv service and a DIAL server, based on which, a mobile phone sends a network wake-up packet to a tv, the NIC network card receives the network wake-up packet, first parses the network wake-up packet and stores application information in the wake-up packet, and sends the network wake-up packet to the main chip, the main chip starts a tv boot according to the network wake-up packet, after the tv is booted, the main chip sends a boot message to the tv service, the tv service starts the DIAL server to respond to a connection request sent by the DIAL client of the mobile phone to establish a connection with the mobile phone, and after the connection is successful, responds to the DIAL client of the mobile phone to indicate that the connection is successful, and at the same time, the tv service reads application information from the NIC network card, and responding to the application information, starting and running the application in the background, simultaneously sending the video to the television service by the mobile phone through the NIC network card and utilizing the chip, running the application running in the background in the foreground after the television service receives the video, and playing the video in the application.

It can be seen from the foregoing step 101 that, after receiving the network wakeup packet, the display device is immediately started, and after the start, the display device establishes a connection with the mobile device, and at the same time, parses the application information, and determines whether a URI of a video exists in the application information, and for a case where the URI of the video exists, the display device does not wait for a successful connection with the mobile terminal to start and run the target application program in the foreground, and when determining that the video to be screened is received, plays the video in the target application program run in the foreground. And simultaneously executing the step of establishing connection with the mobile terminal, and executing the step of analyzing the application information, reading the identification information and the first indication information from the application information, and responding to the first indication information, starting and running the target application program corresponding to the identification information in a background, so that when the video to be projected is determined to be received, the target application program running in the background is switched to the foreground to run and play the video. As for the case of the URI having the video, how to start screen projection in the present display device will be described in detail below, and details thereof will not be repeated here.

Therefore, in the technical solution provided in the embodiment of the present application, when the display device is not turned on, the display device is started in response to the wake-on-lan packet carrying the application information sent by the mobile terminal, and when a connection is established with a mobile terminal, the display device starts and runs the target application program in the background in response to the first indication information in the application information by analyzing the application information sent by the mobile terminal in response to the URI of the video in the application information. Therefore, after the video pushed by the mobile terminal is received, the target application program running in the background is switched to be run in the foreground, so that the video is played by the target application program. Compared with the prior art, in the application, the network connection with the mobile terminal and the starting of the target application program are synchronously carried out, so that the time of a screen projection process can be shortened by applying the technical scheme provided by the application, and the screen projection efficiency can be improved.

In an embodiment of the present application, as shown in fig. 9, if it is determined that the URI of the video exists in the application information, the following step 104 may be further included:

and 104, reading identification information of the application in the mobile terminal and second indication information for indicating that the application program is started in the foreground from the application information, and starting a target application program corresponding to the identification information in the foreground in response to the second indication information so as to play the video corresponding to the URI in the target application program after the target application program is determined to be started successfully.

In this embodiment, based on the above description of the application information, the indication information included in the application information is the second indication information.

Based on the description of the identification information of the application in the mobile terminal, it can be known that the mobile terminal can definitely open the application program corresponding to the URI according to the identification information in the application information by carrying the identification information of the application capable of playing the video corresponding to the URI in the application information.

In this step, after the display device receives the wake-on-lan packet, the display device is immediately started, and after the display device is started, the display device analyzes the application information while establishing a connection with the mobile terminal, and determines whether the URI of the video exists in the application information, and does not need to wait for information pushed by the mobile terminal in case of the URI of the video. And the identification information and the second indication information are read from the application information, and the video corresponding to the URI is directly started and played in a target application program corresponding to the identification information in response to the second indication information.

Based on that, in an embodiment, as described above, if the video information pushed by the mobile terminal is received, it may be determined whether a URI in the pushed video information is consistent with a URI included in the application information, if so, the received URI is dropped, and if not, the pushed video information is played in the target application program.

In another embodiment, in the mobile terminal, it is determined whether the URI in the video information to be pushed is consistent with the URI in the application information, if so, the pushed information is discarded and the prompt information that the video is already being played is prompted, and if not, the video information is sent to the display device to play the pushed video information in the target application program.

For easier understanding, now described with reference to an embodiment of fig. 10, as shown in fig. 10, a controller of the display device includes an NIC network card, a main chip, a tv service, and a DIAL server, based on which, a mobile phone sends a wake-on-lan packet to a tv, the NIC network card receives the wake-on-lan packet, first parses the wake-on-lan packet, stores application information in the wake-on-lan packet, and sends the wake-on-lan packet to the main chip, the main chip starts a tv boot according to the wake-on-lan packet, after the tv boots, the main chip sends a boot message to the tv service, reads the application information from the NIC network card, and in response to the application information, starts an application at a foreground and runs, and plays a video corresponding to a URI in the running application.

As can be seen, in the technical solution provided in the embodiment of the present application, for a case that it is determined that a video URI to be screened exists in the application information, by reading the identification information and the second indication information of the application in the mobile terminal from the application information, in response to the second indication information, a target application program corresponding to the identification information is started in the foreground, so as to play a video corresponding to the URI in the running target application program. Compared with the prior art, the method and the device can save the time for establishing network connection with the mobile phone, the time for receiving the push information sent by the mobile phone, and the time for starting the video playing application, so that the screen projection efficiency can be improved.

In an embodiment of the present application, the step of setting up a DIAL server in the controller and establishing a connection with the mobile terminal may include the following steps:

step A, starting the DIAL service end to respond to a connection request sent by the DIAL client end in the mobile equipment and establish connection with the mobile terminal.

Based on the DIAL protocol, applications on DIAL client devices within the same local area network may discover and launch the same applications on DIAL server devices. Taking the example where the application on the DIAL client device is application a, application a may discover the DIAL server device within the same local area network and launch application a on the DIAL server device if application a is also installed on the DIAL server device.

Based on the above description, the mobile terminal is integrated with a DIAL client, and the display device is integrated with a DIAL server, so that the mobile terminal and the display device can be connected through the signed DIAL protocol. That is, in the case of successful network connection, the DIAL client may actively discover and establish a connection with the DIAL server.

For example, assume that a DIAL client is integrated on a handset and a DIAL server is integrated on a television. When the connection between the mobile phone and the smart television is required to be established, the mobile phone can discover a DIAL server in the same local area network by using a DIAL client, and the DIAL server on the smart television is started, so that the connection between the mobile phone and the smart television can be established.

It should be noted that, the DIAL server is started, and response information indicating successful connection is fed back to the mobile terminal;

based on the step a, if the connection is successful, the method may further include the step B of:

b, feeding back response information indicating successful connection to the mobile terminal; and receiving the video pushed by the mobile terminal, and switching the target application program running in the background to the foreground for running so as to play the video in the target application program.

The mobile terminal is successfully connected with the display device, which means that the mobile terminal can perform information interaction with the video, for example, the mobile terminal can send the video to be pushed.

After starting the DIAL client, the DIAL server of the display equipment responds to the connection request of the DIAL client, responds to the mobile terminal after the connection is successful, and the mobile terminal can interact with the display equipment after receiving the response of the connection success, so that the display equipment sends the video information to be pushed. And for the display device, after sending a response to the mobile terminal, the display device immediately switches the target application program running in the background to the foreground running, so that after receiving the video sent by the mobile terminal, the display device immediately can play the video pushed by the mobile terminal in the target application program running in the foreground.

It can be seen that in the technical solution provided in this application embodiment, the mobile terminal and the display device are installed with an application program of the DIAL protocol, so that the mobile terminal can quickly send and establish a connection with the display device, and after the connection is successful, the video pushed by the mobile terminal is received, and the target application program running on the background is quickly switched to the foreground for running, so that the video can be quickly played in the target application program, and thus, a user can watch the video as uninterrupted as possible, which not only can improve the screen projection efficiency, but also can bring a good experience effect to the user.

In an embodiment of the present application, after the step 101 is executed, the following step B may be further included:

and step B, storing the application information carried by the network awakening packet.

After the application information is analyzed, there may be other information to be executed in the application information, and the application information may be locally stored in order to facilitate subsequent use of the information.

The application information may further include third indication information for indicating to set a starting parameter of the application, and the reading, in the step 102, the identification information of the application in the mobile terminal and the first indication information for indicating to start the application program in the background may include the following step C:

and step C, reading identification information of the application in the mobile terminal, first indication information and third indication information for indicating that the application program is started in the background from the application information.

Based on the above description of the application information, in the present embodiment, the application information includes identification information and indication information, and the indication information includes first indication information and third indication information.

The setting of the start-up parameters of the application may be understood as setting the start-up parameters of the application, so that the application may be in a desired state. These startup parameters may include the size of the playback window, the sharpness of the displayed video image, and the volume of the played video, among others.

For example, the size of the play window includes a full screen, a half screen, and a small screen.

The definition of displaying a video image includes standard definition (standard definition): 720P: 1280x720, full high definition: 1080P: 1920 × 1080(P means Progressive, meaning Progressive scanning), full high definition: 1080I: 1920x1080(I is Interlace, meaning interlaced) and ultra high definition: 4K: 4096 × 2160. Of course, the definition can also be customized to set definition parameters, such as: the resolution may be set at 1930x 1060. The definition can be determined according to the actual situation, which way the parameter is set, and this embodiment is not limited to this.

The parameter of the volume of the played video may be set by a user, or may also be set as a default parameter, and as for the setting of the implementation mode of the volume of the played video, the present embodiment is not limited to this.

Based on step C, one specific embodiment of "in response to the first indication information, starting and running the target application corresponding to the identification information in the background" in step 102 may include the following step D:

and D, responding to the first indication information and the third indication information, setting starting parameters for the target application program corresponding to the identification information, and starting and running the target application program in the background according to the set starting parameters.

The display device acquires the identification information, and can determine the application program responding to the first indication information and the third indication information.

In this embodiment, according to the read identification information, a target application corresponding to the identification information is determined, after the target application is determined, according to the first indication information, a start parameter is set for the target application, and according to the third indication information, according to the set start parameter, the first target application parameter is started in the background and is operated.

For example, assuming that the application information sent by the mobile phone includes identification information of an odds and handicrafts application program, and the third indication information indicates that the application is set to be full screen, high definition and 20 volume, after the smart television reads the application information, the display device determines the odds and handicrafts application program according to the identification information, and sets a starting parameter for the odds and handicrafts application program according to the third indication, so that the odds and handicrafts application program is started and run at the background according to the set starting parameter according to the first indication.

Therefore, in the technical scheme provided by the embodiment of the application, the display device can start the target application program corresponding to the identification information in the background according to the start parameter set by the third indication information by reading the application information, and can start and run the target application program according to the behavior expected by the user, so that the expectation of the user can be met on the basis of improving the screen projection efficiency, and good experience is brought to the user.

At present, most of smart televisions support network applications such as YouTube and Netflix, and users can use corresponding App on mobile phones to push videos in the applications to the televisions for playing through DIAL protocols. Similarly, after the television is in standby, the mobile phone App can wake up the television (WOL/WoWLAN) by sending a network magic packet, and then push the network video to the television to achieve the purpose of video push.

At present, under the condition of television standby, the flow of pushing a video to play by a common mobile phone through a DIAL protocol is generally as follows: the application on the mobile phone first sends the network wakeup packet to start the television, because there is a certain time difference between the DIAL message and the television start behavior, and it cannot be guaranteed that the DIAL message will be sent to the television by hundreds, for example, a common situation is: the television is turned on, but the network is not connected; another situation is that the user cancels the screen-casting task in the process of screen casting. Therefore, the television is often restored to the pre-standby state after being turned on. Then, the television connection network starts a DIAL server of the television connection network, after the application of the mobile phone is connected with the DIAL server, the mobile phone receives a successful connection response and pushes the video to be played to the television, and the television starts the application corresponding to the video to be played to start playing.

For clearer description, now, referring to fig. 11, a DIAL in a mobile terminal sends a network wake-up packet to a display device, the display device controls a power management to start the display device to start up after receiving the network wake-up packet, after starting up, a start-up message is sent to a channel/application management, after receiving the start-up message, the channel/application management switches a channel to a default standby channel, and at this time, a user interface of the display device is in a standby state; meanwhile, after starting up, starting a DIAL server to establish connection with a DIAL client of the mobile terminal, after the connection is successful, responding the DIAL client by the DIAL server to enable the DIAL client to know that the connection is successful, sending the pushed video to the DIAL server by the DIAL client, on one hand, sending DIAL information carrying the video to a user interface by the DIAL server, on the other hand, responding the information that the DIAL client receives the video, and at the moment, starting an application and running in a foreground to enable the video to be played in the application. As can be seen from fig. 11, the time taken for the entire standby front channel screen is long.

As can be seen from the above flow of pushing a video in the prior art and fig. 11, the above flow includes a normal startup process, before a real application is started, a television has a display picture of a channel picture before standby for about several seconds, and after a user sees a television standby picture, it is unclear whether the connection is successful and under what conditions, so that it is clear that the interactivity between the television and the user is poor, and further user experience of television use is affected.

Based on the above technical problem, in an embodiment of the present application, after the display device is started in step 102, the following step E may be further included:

and step E, forbidding execution of switching of a default standby channel, and displaying a page for prompting a user to wait for information in a user interface of the display.

In this step, after the display device prohibits the execution of switching the default standby channel, the user interface of the display device does not display the original standby state.

The page for prompting the waiting information by the user may be displaying the waiting connection in the page, asking you to wait, or waiting for countdown and the like.

If the DIAL connection failure occurs, the information for prompting the user to wait for information is replaced by the information for prompting the user for connection failure or the information for waiting for timeout.

In order to make the page content not boring, a static or dynamic image can be displayed in the page, music and the like can be loaded in the page, and the page can be used for prompting the user to wait for information to be set on top.
