Background technique

At present, most of the smart TV system software is based on the Android platform. The startup process is roughly that the bootloader guides the linux kernel, and then the linux kernel loads the root file system of Android, executes the init process of the Android system, and finally starts the follow-up process of the Android system by the init process. process until the system boot is complete.

The smart TV system based on the Android platform mainly adds TV functions (such as analog television (Analog Television Limited, ATV), digital television (Digital television, DTV)) on the basis of the Android platform. Although the TV functions and Android architecture of each TV manufacturer or TV solution are different, in the user space part, the init process basically starts its TV process. The init process starts system services and daemons in the form of cloning (fork), that is, the processes started by the init process basically run in parallel.

The display of the smart TV system is divided into two layers: Video (video layer, TV layer) and OSD (graphics layer for displaying Android common applications). When video or TV needs to be displayed, the OSD layer can be hidden, or the OSD layer Set to transparent.

In the existing method, the boot animation is displayed on the OSD layer, and the TV picture is displayed on the Video layer, both of which are started simultaneously by the init process and run in parallel. Since the starting sequence of the process of starting the boot animation and the TV screen in parallel is uncertain, when the process of starting the boot animation and the TV screen is not synchronized, a blue screen (TV initialization screen or TV screen) may flash once before the boot animation; It is also possible to play TV sound when the boot animation is playing.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the embodiment of the present invention, after the TV starts for a preset time, the boot animation starts, and monitors the current TV startup progress, obtains the TV startup information, and determines the preliminary play frame of the startup animation based on the acquired startup information and the number of frames of the startup animation rate, to realize the initial synchronization of TV and boot animation. When TV broadcasting carries out phase conversion, if the remaining time of TV starting is not equal to the remaining time of described starting animation playing, adjust the playing frame rate of starting animation based on the starting process information of current TV and the playing process information of starting animation, so that TV startup and startup animation playback end at the same time.

In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

Embodiment one:

FIG. 1 shows a flow chart of a method for starting a TV provided in the first embodiment of the present invention, which is described in detail as follows:

In step S11, after the TV starts for a preset time, the boot animation starts.

In this step, the picture files corresponding to the startup animation can be divided into at least two groups, because the picture files of the first group are set to be played simultaneously with starting the TV, and the picture files of the second group are played simultaneously with the TV. Therefore, the first The background of the picture files in the group can be transparent or opaque, but the background of the picture files in the second group is transparent so as to display the playing TV at the same time. In the embodiment of the present invention, for the convenience of expression, the frames corresponding to the picture files divided into the first group in playing the boot animation are simply referred to as the frames of the boot animation. When the TV is started for a preset time, the boot animation starts.

Optionally, before the boot animation is started, it includes:

A1. Read the picture file of the boot animation and the playback control parameters, the playback control parameters include the number of frames of the boot animation. Among them, the playback control parameters also include: the display size (width and height) of the animation, the frame rate of the animation, and the groups into which the animation is divided, the path type of the group, the number of group loops, etc.

A2. Reorganize the read playback control parameters into program executable objects. Specifically, the read playback control parameters are reorganized according to the animation (animation) structure into an object that is convenient for program execution, and the structure of the object is shown in FIG. 2 . As shown in FIG. 2 , in order to facilitate fast loop playback of picture files, information such as file mapping addresses and texture marks are stored in advance.

Step S12, monitor the current TV start-up progress, and obtain TV start-up information, the TV start-up information includes the current start-up stage of the TV, and the TV includes several stages from start-up to start-up.

Wherein, the TV is pre-divided into a plurality of stages from the start to the end of the start, and each stage has a unique identifier indicating the stage that the TV is currently started.

Step S13, based on the acquired start-up information and the frame number of the start-up animation, determine the initial playback frame rate of the start-up animation, and realize the preliminary synchronization of the TV and the start-up animation.

When the start-up information of the TV includes: the stage J _x of the current start-up of the TV, the time T ₀ from the start of the TV to the current time, and the total time T _h of all stages of the TV start-up, the frame based on the obtained start-up information and the start-up animation Determine the initial playback frame rate of the boot animation, and realize the initial synchronization of the TV and the boot animation, including:

B1. Based on the startup information, calculate the current remaining time (T _h -T ₀ ) for TV startup. Before playing the startup animation, check the time T ₀ taken by the TV from the start to the present and the total time T _h of all stages of the TV start, and subtract the two numbers to determine the remaining time for the TV start. Wherein, the total time of all stages of TV startup may be the total time of all stages of TV startup in a certain history, or may be an average value of the total time of all stages of TV startup in history.

B2. Determine the preliminary playback frame rate of the boot animation based on (T _h -T ₀ )/N, where N is the number of frames of the boot animation. N is a positive integer. Of course, the initial playback frame rate of the startup animation is a value obtained by rounding down (T _h -T ₀ )/N.

Step S14, when the TV broadcast is performing a phase transition, if the remaining time of TV startup is not equal to the remaining time of the startup animation playback, adjust the playback frame rate of the startup animation based on the current TV startup process information and the playback progress information of the startup animation , so that the TV startup and startup animation playback end at the same time, the startup process information of the TV includes the current startup stage of the TV and the remaining time of TV startup, and the playback progress information of the startup animation includes the current playback frame rate of the startup animation And the number of frames that the boot animation did not play.

Wherein, when TV broadcasting performs phase conversion, if the remaining time of TV startup is not equal to the remaining time of described boot animation playback, adjust the playback frame rate of boot animation based on the current TV startup process information and the playback process information of boot animation, To make the TV start and start animation playback end at the same time, specifically include:

C1. When the TV start-up process undergoes stage conversion, obtain the remaining time for TV start-up; when the TV starts up to the corresponding logo of each stage, determine that the TV start-up process performs stage conversion. At this time, according to the total time required for TV start-up of all stages The time and the time required to boot up to the present, determine the time remaining for the TV to boot up.

C2. Calculate the remaining playing time of the boot animation based on the current playback frame rate of the boot animation and the number of unplayed frames of the boot animation. Specifically, the playback frame rate is the number of frames played per unit time, and the playback frame rate is equal to the number of unplayed frames of the startup animation and the startup animation. Therefore, based on the current playback frame rate of the boot animation and the number of unplayed frames of the boot animation, the remaining playing time of the boot animation can be obtained.

C3. Judging whether the remaining time of TV startup is equal to the remaining time of playing the startup animation, if so, go to step C4, otherwise go to step C5.

C4. Keep the current playback frame rate and play the startup animation. If the remaining time of TV startup is equal to the remaining playing time of the startup animation, it indicates that the TV startup and the playback of the startup animation continue to be synchronized. At this time, there is no need to adjust the playback frame rate of the startup animation.

C5. Adjust the playback frame rate of the startup animation based on the remaining time of TV startup and the number of unplayed frames of the startup animation. Specifically, the number of unplayed frames of the startup animation is divided by the remaining time for starting the TV, and the obtained quotient is the frame rate of the unplayed frames of the startup animation. Of course, the frame rate of the frame that is not played in the startup animation is the value obtained by rounding down the obtained quotient.

In this step, since the playback frame rate of the startup animation is corrected at each stage, the playback of the startup animation is synchronized with the TV startup in time, so that when the TV startup ends, the startup animation (i.e. the first group of startup animation) Picture file) also finishes playing, and at this moment, while starting to play the TV that has started and ended, play the second group of picture files of the boot animation.

Optionally, the adjustment of the playback frame rate of the boot animation based on the remaining time of TV startup and the unplayed frame number of the boot animation specifically includes:

Record the time t _b0 before playing each frame of boot animation and the time t _b1 after playing;

Determine whether [t _x -(t _b1 -t _b0 )] is greater than the preset value, if so, pause [t _x -(t _b1 -t _b0 )] and continue to play the next frame of the current frame, otherwise, skip the current frame Continue to play after the next frame of the frame, and the t _x is the pause time of each frame of the boot animation.

Among them, (t _b1 -t _b0 ) is the time spent playing one frame of boot animation, [t _x -(t _b1 -t _b0 )] is the pause time of playing two frames of boot animation, which can be passed through usleep[t _x -( t _b1 -t _b0 )] statement forces a pause in the frame of the boot animation. Among them, the preset value can be 10 milliseconds. For example, if the calculated [t _x -(t _b1 -t _b0 )] is less than 10 milliseconds when playing the first frame of the startup animation, skip the second frame and play the first frame directly. Three frames, otherwise, after pausing [t _x -(t _b1 -t _b0 )], continue to play the second frame. Of course, the preset value can also be set to other values, which is not limited here.

Optionally, when performing stage conversion during TV playback, if the remaining time of TV startup is not equal to the remaining time of the startup animation playback, the startup animation is adjusted based on the current TV startup process information and the playback progress information of the startup animation The playback frame rate, so that when the TV starts and the boot animation ends at the same time, including:

Before playing each frame of the boot animation and after playing each frame of the boot animation, monitor whether a signal to stop playing the boot animation is received, so that when the signal to stop playing the boot animation is received, the playback of the boot animation is stopped in time.

In order to strictly control the synchronization between TV startup and boot animation playback, at the beginning and end of each frame of the boot animation, it is monitored whether a signal to stop playing the boot animation is received, and if received, then stop playing the boot animation, otherwise , continue playing. Of course, at the beginning and end of each cycle of each group of the boot animation, it is also monitored whether a signal to stop playing the boot animation is received.

In the first embodiment of the present invention, after the TV starts for a preset time, the boot animation starts, and monitors the current TV startup progress, obtains the TV startup information, and determines the startup animation frame number based on the acquired startup information and the number of frames of the startup animation. Preliminary playback frame rate to achieve preliminary synchronization of TV and boot animation. When TV broadcasting carries out phase conversion, if the remaining time of TV starting is not equal to the remaining time of described starting animation playing, adjust the playing frame rate of starting animation based on the starting process information of current TV and the playing process information of starting animation, so that TV startup and startup animation playback end at the same time. Since the playback frame rate of the boot animation is related to the TV startup, and during the playback of the boot animation, the playback frame rate of the frames not played in the startup animation is corrected in time according to the follow-up TV startup information, so that the playback of the startup animation The time is the same as the time when the TV starts up, so as to solve the phenomenon (such as flickering phenomenon) caused by the asynchronous playback of TV start-up and boot animation during the TV start-up process.

It should be understood that in the embodiment of the present invention, the sequence numbers of the above-mentioned processes do not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, rather than the implementation process of the embodiment of the present invention. constitute any limitation.

Wherein, the picture files corresponding to the startup animation can be divided into at least two groups. Since the picture files of the first group are set to be played simultaneously with starting the TV, and the picture files of the second group are played simultaneously with the TV, therefore, the first group The background of the picture file can be transparent or opaque, but the background of the second group of picture files is transparent so as to display the playing TV at the same time. In the embodiment of the present invention, for the convenience of expression, the frames corresponding to the picture files divided into the first group in playing the startup animation are simply referred to as the frames of the startup animation.

Optionally, before starting the boot animation, it includes: reading a picture file of the boot animation and playing control parameters, the playback control parameters including the number of frames of the boot animation. Reassemble the read playback control parameters into a program executable object.

The startup information acquisition unit 32 is configured to monitor the current startup progress of the TV and acquire TV startup information, the TV startup information includes the current startup stage of the TV, and the TV includes several stages from startup to startup.

Wherein, the initial playback frame rate of the startup animation is a value obtained by rounding down (T _h -T ₀ )/N.

The playback frame rate correction unit 34 is used to adjust the start-up process information based on the current TV start-up process information and the start-up animation play process information if the remaining time of the TV start is not equal to the remaining time of the start-up animation when the TV is played for stage conversion. The playback frame rate of the boot animation, so that the TV starts and the boot animation playback ends simultaneously, and the startup process information of the TV includes the current startup stage of the TV and the remaining time of the TV startup, and the playback process information of the boot animation includes boot The current playback frame rate of the animation and the number of unplayed frames of the startup animation.
