The local keys configured by the television are used as basic components of the television, and the functions of the local keys are weakened more and more from the birth of a remote controller; the local keys are also simplified more and more, for example, from 7 keys to 5 keys to the current common single keys, and the local keys only bear the original basic functions of the television.
For the more and more abundant network contents supported by the smart television, the control is usually performed through a remote controller. The local key is not applied to control of network content as the simplest television control component. With the network application showing the network content to the television in a virtual channel mode, the menu of the local key of the display device provided by the application supports to display the network virtual channel parallel to the physical channel, and realizes the selection and play control of the virtual channel by multiplexing the local key.
In some embodiments, in addition to being a normal video application, the online video application also supports an online live broadcast function in a plurality of application programs of the smart television desktop, and can realize live broadcast network channels.
In some embodiments, if a user who is watching live or local video on a physical channel such as TV, AV, HDMI needs to watch live video on a network channel of an online video application, the user needs to use a remote controller to select the online video in a desktop application program, then start the online video application, further select a live function in the online video application, and finally realize live watching of the network channel.
It can be found that a plurality of operation steps are required in the network channel live broadcast process, and each operation is quite complicated if the user takes the network channel live broadcast of the online video application as a daily preference.
In some embodiments, the controller controls the first menu to display a virtual channel for live broadcasting of an incoming network channel, the virtual channel is usually displayed in parallel with other physical channels, and a user can directly enter the live broadcasting of the network channel in the application program through simple selection operation.
When a user presses a local key, the controller receives a first instruction which is generated by the operation of the local key and used for displaying a first menu, and the controller sends a second instruction containing the equipment identifier to the cloud server.
For example, when the smart television locally has only 1 online video application capable of broadcasting the network channel, the second instruction can carry the device identifier of the smart television, the device identifier can reflect information such as account information of the smart television, the rights of online video application and the like, and the server can determine whether the online video has the rights of broadcasting the network channel locally through the device identifier carried by the second instruction.
If the online video application has the authority and the capability of the local live network channel, the second instruction will cause the server to determine the virtual channel which can be displayed in parallel with the physical channel in the smart television, so as to realize that the physical channel and the virtual channel are displayed in the first menu at the same time, and the virtual channel corresponds to the online video application which can play the network channel in the smart television.
In some embodiments, the server provided by the application comprises a second controller, and after a user presses a local key of the smart television, the second controller can receive a second instruction sent by the smart television, wherein the second instruction comprises a device identifier of the smart television, and the device identifier can reflect information such as account information of the smart television, on-line video application permission and the like.
For example, through the device information included in the second instruction, the server second controller determines that the authority of the online video application in the smart television allows the television end to live the network channel, and the second controller determines that the first virtual channel can be provided to the smart television, where the first virtual channel corresponds to the first application that is installed in the smart television and can support playing the network channel, that is, the online video application in fig. 5B.
After the second controller of the server determines that the online video application can be configured as a virtual channel, a third instruction is issued to the intelligent television, wherein the third instruction comprises a first virtual channel, the third instruction can be used for enabling the intelligent television to configure the first virtual channel corresponding to the first menu display according to the first virtual channel information contained in the third instruction, namely, the first virtual channel and the physical channel are configured to be displayed in parallel, and a mapping operation relation is established between the first virtual channel and the network channel live broadcast of the online video application.
In some embodiments, the first controller of the smart television receives a third instruction sent by the server, where the third instruction includes the first virtual channel determined by the second controller of the server.
Based on the first virtual channel information contained in the third instruction, the first controller of the intelligent television controls the television user interface to display a first menu containing the first virtual channel, namely, after the user presses a local key, the first menu can display the display effect comprising the physical channel and the virtual channel.
It should be noted that, after the user selects the first virtual channel and performs the confirmation operation, the first controller will start the corresponding first application, that is, the online video application in fig. 5B, to live the corresponding network channel included in the first virtual channel.
In some embodiments, for an online video application displayed on the desktop of the smart television, the online video application may be displayed as an online video in the first menu, the TV may also be displayed in other forms, the display form of which is determined by the server, and the display form is sent to the smart television through a third instruction to control the first menu of the smart television to display.
In some embodiments, the display device provided by the application can quickly display and switch the physical channel and the virtual channel through the local key without a remote controller. In order to realize the purpose that the display equipment realizes virtual channel display and operation through the local key, the display equipment comprises a local key menu module, a virtual channel data management module, an application management module, a physical channel management module, an application program manager and an external support server at the system level.
The local key menu module can display information such as physical channels, virtual channels and the like and perform quick switching control; the virtual channel data management module is responsible for acquiring the configurable virtual channel data of the current country, or the current network, or the current account number from the cloud server, providing the configurable virtual channel data for the local key menu for display, and re-acquiring the virtual channel data management module when the country, or the network, or the account number changes; the application management module controls the virtual channel to be opened in the same way as the starting application program, and communicates with the APM when the virtual channel is switched in the user interface, so that the starting of the corresponding application program is realized; the physical channel management module is responsible for providing data of a physical channel for a local key menu and providing an interface for switching the physical channel to communicate with the APM; the server is responsible for configuring available virtual channels; the APM unifies the application and the physical channel into source switching, records the current channel type, and calls the channel management related interface of the TV middleware for processing when the physical channel is in the process of starting or closing the process corresponding to the specific application if the application is in the process of starting or closing the process corresponding to the specific application, and the system architecture is shown in figure 6.
For example, when the smart television supports the virtual channel, the first controller configures the first virtual channel and the first physical channel as selectable items of the video source, and displays the selectable items in parallel in the first menu for the user to operate.
When the first virtual channel is started, the first controller controls the corresponding first application to be started on the user interface; when the first physical channel is started, the control display device calls the television middleware to switch to the corresponding video source through the bottom channel.
In some embodiments, after the smart television is started, the user operates a local key, and the first controller determines whether the current user interface has a displayed menu page; if the displayed menu interface exists, the controller cancels the display to exit the current display page; if no menu page is displayed, the first controller starts a first menu creation and display flow;
the method comprises the steps that a first controller obtains a physical channel supported by the intelligent television from a physical channel management module and pushes the physical channel to a first menu to be displayed; then the first controller continuously judges whether the intelligent television has supportable virtual channels or not; if yes, pushing the supported virtual channel to a first menu to be displayed; then pushing other contents to be displayed to a first menu to be displayed, wherein the first menu can comprise channel addition and subtraction, finding out a remote controller, turning off a key and the like;
the first controller obtains the names of the currently determined physical channels and virtual channels, namely channel types, from the application program manager according to the display items in the first menu to be displayed; the further first controller judges the type of the current signal source channel of the intelligent television to determine the position of the current signal source channel in the first menu, and controls the signal source channel with the focus on the current intelligent television to perform highlighting display when the first menu is displayed on the user interface so as to complete control display of the first menu, wherein the logic flow of the control display is shown in figure 7.
Fig. 5C is a schematic diagram of a smart tv local key menu user interface according to another embodiment of the present application.
In some embodiments, the smart tv has installed a plurality of video applications, and the controller is to control the first menu to display a first virtual channel and a second virtual channel, wherein the first virtual channel and the second virtual channel respectively correspond to the installed applications capable of supporting live webtv.
For example, in the smart tv desktop application of fig. 5C, 3 video applications are included, namely online video, video of a small poly, and video of a cow. Wherein, the small-sized video and the online video support live broadcast network channels, and the cattle video does not support live broadcast network channels.
After the user presses the local key, the first controller controls the first menu to display the virtual channel online video corresponding to the online video, the TV and the virtual channel small-focus video corresponding to the small-focus video by receiving a third instruction from the server, wherein the online video, the small-focus video, the TV are the first virtual channel and the second virtual channel.
It should be noted that, for a video application that does not support live network channels locally on the smart tv, the first menu will not display its corresponding virtual channel.
In some embodiments, the first menu may further include a second physical channel, and/or a second virtual channel, and/or a volume control, and/or a channel control, and/or a shutdown control. For example, the first menu physical channel in fig. 5C includes TV, AV, HDMI, and the like, and further includes 2 volume adjustment buttons, and 2 virtual channels online video.
Fig. 5D is a schematic diagram of a smart tv local key menu user interface according to another embodiment of the present application.
In some embodiments, the signal source of the smart TV is a physical channel TV, i.e. a normal broadcast television signal source is used. When the channel list is configured as a default display, the user interface at the TV signal source is as shown in fig. 5D;
after the user presses the local key, the first controller controls the first menu to be displayed in the user interface as shown in the figure, and the focus is positioned on the TV physical channel option, wherein the channel list comprises a center 1 table to a center 6 table as shown in the figure, and the switching between the virtual channel and the physical channel is realized by the user operating the local key multiplexing.
In some embodiments, when a user operates a local key to control a focus of the user interface to switch from a first virtual channel to a first physical channel adjacent to its location, the first controller will obtain a press time applied to the local key, and through analysis of the press time, the first controller will identify a different local key press operation as a moving focus, and confirm the operation.
For example, based on the user interface shown in fig. 5D, the user needs to switch the signal source from the TV physical channel to the online video;
And when the pressing time is smaller than a first threshold value, controlling the focus to move from the physical channel TV to the first virtual channel online video. For example, the first threshold is set to 3 seconds, and when the user presses the native key for less than 3 seconds each time, the first controller will recognize this native key operation as a moving focus, and the focus in the user interface will move from the physical channel TV to the online video on a row-by-row basis based on the short pressing operation of the 3 native keys, as shown in FIG. 5E.
In some embodiments, when the user interface focus has moved to the virtual channel online video of the first menu, the user may press the local key again for a long time at this time, and when the controller detects that the pressing time is greater than or equal to the first threshold, the first controller will control the online video of the first application corresponding to the virtual channel of the TV to start, so as to play the network channel contained in the virtual channel of the TV on the user interface.
For example, when the first threshold is set to 3 seconds, the focus is on the online video, the TV virtual channel, and when the pressing time of the user pressing the local key for a long time reaches more than 3 seconds, the first controller will start the online video application in the user interface, so as to enable the user interface to directly play the network channel contained in the user interface, so that the playing effect of switching from the physical channel to the virtual channel can be achieved, and control the first menu to cancel the display on the user interface, as shown in fig. 5F.
The intelligent television playing user interface in the online video and TV virtual channel comprises a plurality of network channels and also comprises advertisement promotion sites of network channel content service providers.
It can be found that in the above embodiment, the user can display the virtual channel on the first menu of the smart television only through the local key, and can realize the switching play operation of the virtual channel through the simple multiplexing of the local key.
In some embodiments, when the local key menu, i.e. the first menu, is in a display state, the first controller of the smart television receives a pressing action of the local key, i.e. detects and identifies an operation intention of a user on the local key;
After the user presses the local key, the first controller creates a timer in the system, for example, a 3s confirmation timer can be created; after the timer is established, the first controller monitors whether the lifting action of the local key is received or not;
If the lifting action of the local key is received before the timer arrives, the first controller clears the 3s confirmation timer and controls the focus to move down line by line in a first menu of the user interface so as to realize the pressing of the mobile user and the surface cursor following the local key;
If the lifting action of the local key is not received before the timer arrives, the first controller judges that the operation of the local key by the user is a confirmation operation; the first controller judges the option type of the current focus, if the current focus is located in a physical channel, the first controller calls an APM (application manager) switching channel interface, and the APM calls a bottom channel switching mode to enter a corresponding physical channel so as to successfully switch to the physical channel; if the current focus is located in the virtual channel, the first controller enables the application management module to call the APM channel interface by calling the application management module to start the application process, records the type of the current channel in the first menu, sends an application start message to the UI user interface after the corresponding application is started, and the user interface is displayed and enters the corresponding application program to play the corresponding virtual channel, so that the switching process of the virtual channel is completed, as shown in fig. 8.
