In the process of starting up, image quality processing is required to be carried out on the starting-up advertisement, and an image quality processing process is required to be loaded by an initialization process (Init) started by a kernel process (Kenel) after the kernel process (Kenel) is started, so that a starting-up video is required to be carried out after the initialization process is started, as shown in the figure, in S301-S304, a starting-up guide process (Boot) is started after a mainboard is powered on, the starting-up guide process starts the kernel process, and the kernel process starts the initialization process; after the initialization process is started, on one hand, in S305-S307, a startup video service (Bootvideo) is called to obtain startup video data, a player (player) is started to decode the startup video data, perform image quality processing and the like, processed startup video frames are sent to a video layer to be played, at the moment, the smart television displays the pictures of startup video playing, the smart television is not started, and the smart television cannot respond to user operation; on the other hand, in S308 to S310, the initialization process starts a desktop launcher (launcher) to enable the desktop launcher to obtain system homepage data and send the system homepage data to a graphics synthesizer (surfactin), the graphics synthesizer is a system service for graphics processing, the graphics synthesizer processes the system homepage data, such as graphics synthesis, rendering, and the like, because the playing duration of the startup video is greater than the starting duration of the desktop launcher, the graphics synthesizer needs to wait for the startup video to be played after completing the processing of the system homepage data, after the startup video is played, the graphics synthesizer displays the system homepage on a graphics layer, at this time, the smart television displays the system homepage, and the smart television enters a working mode and can respond to the operation of the user.
In a starting-up process of the smart television in a traditional mode, as a starting-up video is played in a video layer, and a module for video processing is established only after a kernel process is started, the starting-up video needs to be processed and played after an initialization process is started; the display priority of the startup video is higher than that of the system homepage, and the graphic synthesizer can display the system homepage on the graphic layer only after the startup video is played; the time between the power-on of the mainboard and the display of the homepage of the system is long, and the user experience is influenced.
Based on the boot flow chart of fig. 3, if the boot type is the boot type in the wake-up mode, the initialization process needs to call a signal source switching service after being started, the signal source switching service determines a target signal source and obtains data corresponding to the target signal source, and after the boot video is played, the target signal source is played in the video layer. In the process, because only one video layer is provided for the smart television, the playing of the startup video occupies the video layer resource of the playing target signal source, and the playing interface of the target signal source can be displayed only after the startup video releases the video layer resource, so that the waiting time for displaying the target signal source is prolonged, and the video layer resource conflict is caused.
In order to solve the problem of conflict of video layer resources and improve user experience, the embodiment of the application provides an intelligent television and a starting method applied to the intelligent television.
Referring to fig. 4, a schematic structural diagram of a smart television provided in the embodiment of the present application schematically illustrates components related to the embodiment of the present application.
As shown, the smart tv 100 includes a controller 210, a display 280, and a memory 290. These assemblies may correspond to some extent to the central subassembly of fig. 2.
The memory 290 stores an operating system 2911 for driving the smart television 100, where the operating system 2911 may be an Android operating system or other operating systems, which is not limited in this application.
The operating system 2911 may be divided into, from the top level to the bottom level: an application layer 2912, a framework layer 2913, and a system kernel 2914.
An application layer 2912 for direct interaction with the user. The application layer 2912 includes various application programs to enable interaction with a user.
The framework layer 2913 includes various services required for the application layer 2912. The various services may be, for example, a player, a signal source switching service, a power-on video service, a desktop launcher, a graphics synthesizer, etc., as described in connection with embodiments of the present application.
The system kernel 2914 is configured to provide core system services for the smart television 100, such as: boot up, file management, memory management, process management, network management, and the like.
The controller 210 implements user operations through various software control programs stored in the memory 290 in response to the user operations.
Specifically, in this embodiment of the application, the controller 210 instructs, in response to a start instruction of the smart television, the player to start, decode the start video, and send a start video frame obtained by decoding to the graphics synthesizer, so that the graphics synthesizer sets the first graphics layer as the topmost layer, and plays the start video in the first graphics layer.
Referring to fig. 5, a flowchart of a power-on method provided in the embodiment of the present application is shown, where the power-on method may be implemented based on the smart television shown in fig. 2 and fig. 4.
As shown, the process includes:
s501: the player decodes the set-up video in response to the start-up instruction.
Specifically, a user can operate a power key of a remote controller or perform screen pushing operation through a mobile terminal, send a power-on instruction to the smart television in the standby mode, and in response, power a main board of the smart television and start a power-on bootstrap program (Boot). In one case, after the boot program is started, the kernel is started, the initialization process is started after the kernel is started, and after the initialization process is started, a start instruction is sent to the player so that the player can respond to the start instruction to decode the startup video; in another case, after the boot program is started, a start instruction is sent to the player, so that the player decodes the boot video in response to the start instruction.
S502: and the player sends the decoded boot video frame to a graphics synthesizer so that the graphics synthesizer plays the boot video on a first graphics layer, wherein the first graphics layer is set as the topmost layer.
In some embodiments, the color coding mode of the startup video is YUV, and since the graphics synthesizer only receives RGB signals, in S502, if the signal format of the startup video frame decoded by the player is RGB, the player can directly send the startup video frame decoded by the player to the graphics synthesizer for playing; if the signal format of the startup video frame decoded by the player is YUV, the player needs to convert the signal format of the decoded startup video frame from YUV to RGB and then send the signal format to the graphic synthesizer.
The formula for converting the signal format from YUV to RGB is as follows:
R＝Y+1.4075×(V-128) (1)
G＝Y-0.3455×(U-128)-0.7169×(V-128) (2)
B＝Y+1.779×(U-128) (3)
wherein R is a red pixel value, G is a green pixel value, B is a blue pixel value, Y is an significance, U is a chroma, and V is a concentration.
In an implementation scenario, before S501, the boot program sends, in response to a display device boot instruction, start instructions to the player and the kernel, respectively, and the start of the kernel and the start of the player are executed in parallel; and starting a system initialization process after the kernel is started, calling a desktop starter after the system initialization process is started, and sending system homepage data of the display equipment to the graphic synthesizer by the desktop starter. The graphic synthesizer stops playing the startup video and sets a second graphic layer of the display system homepage as the topmost layer; or after the startup video is played, the graphics synthesizer sets the second graphics layer of the display system homepage as the topmost layer.
In another realizable scenario, before S501, the boot program starts the kernel in response to the display device boot instruction, and the kernel starts the system initialization process after being started; and sending a starting instruction to the player and the desktop starter after the system initialization process is started.
Optionally, after the system initialization process is started, a signal source switching service is called, and the signal source switching service and the desktop starter are executed in parallel; the signal source switching service determines a starting type corresponding to a starting instruction of the display equipment; and if the starting type corresponding to the starting instruction of the display equipment is the starting type in the wake-up mode, the signal source switching service acquires the data of the target signal source and plays the target signal source in a video layer.
Optionally, the playing, by the signal source switching service, the target signal source in the video layer includes: the signal source switching service prevents the graphic synthesizer from setting a second graphic layer of a display system homepage as the topmost layer and/or setting a first graphic layer for displaying the boot advertisement as the topmost layer, and playing a target signal source on a video layer; or, the signal source switching service prevents the graphic synthesizer from setting a second graphic layer of the display system homepage as the topmost layer, and after the startup video playing is finished, the target signal source is played on the video layer.
In some embodiments, the preventing the graphics compositor from setting the second graphics layer of the presentation system home page to be topmost and/or the first graphics layer of the presentation start-up advertisement to be topmost may be a thread that ends presentation of the system home page and/or a thread that presents the start-up advertisement.
The following describes the boot process shown in fig. 5 in detail with reference to fig. 6, fig. 7, and fig. 8, taking an intelligent phone based on an Android operating system as an example.
Referring to fig. 6, a power-on flowchart of the smart television provided in the embodiment of the present application shows a power-on process of the smart television in the wake-up mode power-on type.
As shown in the figure, in S601 to S603, the boot process is started after the motherboard is powered on, the kernel is started after the boot process is started, and the initialization process is started after the kernel is started.
Since the boot type corresponding to the boot instruction is the boot type of the wake-up mode, after the initialization process is started, on one hand, in S604, the desktop starter is started, and the desktop starter acquires the system homepage data after being started and sends the system homepage data to the graphic synthesizer; on one hand, in S605, the player is started, and after the player is started, the player acquires boot video data, decodes the boot video data, converts the signal format, and sends the processed boot video frame to the graphics synthesizer; on the other hand, in S606, a signal source switching service is called, the signal source switching service acquires data of a target signal source after being called, and sends indication information that a system homepage is not displayed to the graphic synthesizer, and in practical applications, the signal source switching service further needs to process (not shown in the figure), such as decoding, rendering, and the like, the data of the target signal source according to different types according to the type of the target signal source, for example, according to ATV, DTV, and the like.
In S607, the graphics synthesizer receives the startup video, the system homepage, and the indication information (the sequence of the three is not limited in this application), sets the first graphics layer playing the startup video as the topmost layer, i.e., plays the startup video, and does not set the second graphics layer displaying the system homepage as the topmost layer, i.e., does not display the system homepage, according to the indication information sent by the signal source switching service.
In S608, the signal source switching service completes processing of the target signal source, and after the startup video playing is completed, that is, after the screen resource is released, the target signal source is played in the video layer.
Optionally, in S608, after the signal source switching service completes processing of the target signal source, the target signal source is directly played in the video layer without waiting for the completion of the startup video playing, so as to shorten the startup time.
In the booting process shown in fig. 6, since the booting video is played in the graphics layer, and the video layer resources are unoccupied and in an idle state, the conflict of the video layer resources is avoided.
Referring to fig. 7, a power-on flowchart of the smart television provided in the embodiment of the present application shows a power-on process of the smart television in the wake-up mode power-on type.
As shown in the figure, in S701, the boot process is started after the motherboard is powered on, and the kernel process and the player are simultaneously started after the boot process is started.
In S702 to S703, the player acquires boot video data after being started, decodes the boot video data, converts the signal format, and sends the processed boot video frame to the graphics synthesizer.
In S704 to S705, the kernel process starts the initialization process after being started. Because the boot type corresponding to the boot instruction is the boot type of the wake-up mode, after the initialization process is started, on one hand, in S706, a desktop starter is started, and the desktop starter acquires system homepage data after being started and sends the system homepage data to the graphic synthesizer; on the other hand, in S707, a signal source switching service is called, the signal source switching service acquires data of a target signal source after being called, and sends instruction information for not displaying a system homepage to the graphic synthesizer, and in practical application, the signal source switching service further needs to process (not shown in the figure), such as decoding, rendering, and the like, the data of the target signal source according to different types according to the type of the target signal source, such as ATV, DTV, and the like.
In S703, after the graphics synthesizer receives the startup video, the startup video layer is played on the first graphics layer, the first graphics layer is set as the topmost layer, and after the startup video is played, the second graphics layer that displays the system homepage is not set as the topmost layer according to the indication information sent by the signal source switching service, that is, the system homepage is not displayed.
In S708, the signal source switching service completes processing of the target signal source, and after the startup video playing is completed, i.e., after the screen resource is released, the target signal source is played in the video layer.
Optionally, in S708, after the signal source switching service completes processing of the target signal source, the target signal source is directly played in the video layer without waiting for the completion of the startup video playing, so as to shorten the startup duration.
In the booting process shown in fig. 7, since the booting video is played in the graphics layer, it is not necessary to load the image quality processing module to process the booting video after the initialization process is started, and the player is started while the kernel is started after the boot process is started, so that the processing and playing of the booting video are advanced, and the booting duration is shortened; meanwhile, the signal source switching service and the desktop starter are executed simultaneously, so that extra time length cannot be increased in the starting process in the awakening mode, on the contrary, the starting video is played in the graphic layer, and the unoccupied video layer resources are in an idle state, so that the conflict of the video layer resources is avoided.
Referring to fig. 8, a flow chart of turning on the smart television according to the embodiment of the present application exemplarily shows a turning on flow of the smart television in a conventional mode turning on type.
As shown in the figure, in S801, the boot process is started after the motherboard is powered on, and the kernel process and the player are simultaneously started after the boot process is started.
In S802, the player acquires the boot video data after being started, decodes the boot video data, converts the signal format, and sends the processed boot video frame to the graphics synthesizer.
In S803 to S805, the kernel process starts the initialization process after being started, the desktop starter starts the initialization process after being started, and the desktop starter acquires the system homepage data and transmits the system homepage data to the graphics compositor after being started.
In S806 to S807, since the processing duration of the boot video is less than the boot duration of the desktop initiator, and the graphics compositor preferentially receives the boot video, the graphics compositor sets the first graphics layer as the topmost layer, plays the boot video frame on the first graphics layer, and sets the second graphics layer for displaying the system homepage on the top layer after the boot video is played to release the screen resources.
Optionally, in S806 to S807, after receiving the system homepage data sent by the desktop launcher, the graphics compositor may directly place the second graphics layer for displaying the system homepage on the top layer, so as to further shorten the booting time.
In the boot process shown in fig. 8, since the boot video is played in the graphics layer, it is not necessary to load the image quality processing module to process the boot video after the initialization process is started, and the player is started while the kernel is started after the boot process is started, so that the boot video is processed and played in advance, and the boot duration is shortened.
Based on the boot processes shown in fig. 7 and 8, fig. 9 exemplarily shows a time comparison diagram of two boot processes.
As shown in the figure, the startup boot process starting time is 3 seconds(s), the kernel process starting time is 1 second, the initialization process starting time is 1 second, the desktop starter starting time is 6 seconds, and the startup video playing time is 15 seconds. By adopting the starting-up flow shown in fig. 3, the desktop starter and the starting-up video are simultaneously executed in parallel after the initialization process, and the total starting-up time is 20 seconds from the power-on of the mainboard to the display of the system homepage; by adopting the booting process shown in fig. 7 and 8, after the booting process is started, the kernel process and the booting video are executed simultaneously and in parallel, because the playing time of the booting video is longer than the starting time of the kernel process, the initialization process and the desktop starter, the starting of the initialization process, the desktop starter and the like can be executed while the booting video is executed, and the total booting time is 18 seconds from the power-on of the main board to the display of the system homepage.
In the foregoing embodiment of the present application, in response to a start instruction, the player decodes the boot video, and sends a boot video frame obtained by decoding to the graphics compositor, so that the graphics compositor plays the boot video on a first graphics layer, where the first graphics layer is set as a topmost layer. Because the decoded startup video is placed in the graphic layer for playing, the video layer resources are not occupied, and the conflict of the video layer resources is avoided. The present application is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the application.
