technical field

The present invention relates to the technical field of communication, and more specifically, to a mobile terminal and a method for improving the drawing speed of a screen interface.

Background technique

In the past, the method used to draw the screen interface was to refresh the screen and load and draw picture and video resources at the same time. This will lead to high usage of the CPU, resulting in a heavy load on the terminal, resulting in some applications not being able to be successfully completed, such as incomplete drawing of the video interface, or the situation of being stuck.

At present, most mobile phones use hardware decoding. Hardware decoding requires hardware to have a hardware decoding module, related drivers, suitable playback software, and correct settings for the playback software. Without any of these, the hardware decoding function cannot be enabled.

The advantages of hardware decoding are high efficiency, low power consumption, and low thermal power consumption. The disadvantages are the lack of strong support (including filters, subtitles, etc.), and relatively large limitations (such as the failure of the energy-saving function of the terminal after hardware decoding is turned on, etc.) ), the terminal CPU usage is too high, and the settings are more complicated.

Therefore, it is necessary to propose a new technology to overcome the above drawbacks.

Detailed ways

The invention solves the problem of too long interface drawing delay when the mobile terminal uses multimedia applications under the condition of realizing multimedia codec software.

Main idea of the present invention is:

When the multimedia application is playing, other high-priority applications will respond to the high-priority application first when they arrive; pause the media application or exit the application so that the mobile terminal can respond to other applications; the case of using soft codec Next, the screen overlay operation is not performed when the video is initialized, reducing or not refreshing the screen, and at the same time, the image resources used for drawing are moved to the memory to complete the interface drawing; then the underlying layer is notified to open the device, and the screen is played.

The specific implementation principles and processing procedures of the present invention will be described below in conjunction with the accompanying drawings.

Please refer to FIG. 1 , which is a schematic diagram of the composition of the mobile terminal according to the embodiment of the present invention. The mobile terminal of the present invention includes an application management function module, an interface drawing function module and a video playback function module.

The application management function module is used to realize the management of upper layer applications of the mobile terminal and the key response of the mobile terminal.

The interface drawing function module moves the resources to be drawn into the memory to complete the interface drawing.

The video playing function module is used for initializing audio and video equipment to realize multimedia soft decoding and flashing video frames to LCD to display video images.

Please refer to FIG. 2 , which is a schematic flowchart of a method for improving the drawing speed of a screen interface according to an embodiment of the present invention, which includes the following steps:

S201: start an application;

The mobile terminal activates the function of increasing the interface drawing speed. This function can be set by the user to be on or off, or it can be started automatically when the terminal is turned on.

S202: Initialize the device;

After getting the message of initializing the device from the upper thread, the lower layer will set some parameters related to the playback, such as the size of the video playback area, the playback mode (full screen or half screen playback), set the audio channel, check the status of the earphone, pre-set Set the key color and complete the initialization of video and audio devices, instead of continuing to operate the device and turn on the device (if the device is turned on next, it will refresh the LCD and occupy CPU resources). Notify the upper and lower layers that initialization is complete.

S203: resource loading;

After the audio and video devices are initialized in the lower layer, a message response is received, and the image resource is loaded into the memory for interface drawing. At present, most of the storage resources of the current capacity reduction technology are stored in the file system, and the image resource is searched in the file system through the unique ID of the image and loaded into the memory.

S204: draw the screen;

After the image resources of the video player are loaded, there are no other actions in the lower layer that occupy the resources of the processor. At this time, the interface is drawn, and the drawing interface is completed through the drawing function of the GUI under the condition of sufficient resources, because the processing resources can be used to the maximum at this time. , so the drawing of the interface can be completed immediately, and the user can immediately feel that the video application has been opened. Improve user visual experience.

S205: Turn on audio and video equipment;

After the drawing is completed, the channel message is sent directly to the lower layer, which is used to notify the lower layer to open the device and superimpose the set key color value on the screen of the mobile terminal. At this time, a separate thread will be created to refresh the screen to complete the video data on the screen. Drawing on LCD.

S206: Play a video.

Next, use soft decoding to decode video data, start video frame deframing, and superimpose the obtained data frame and key color on the LCD through the thread that has been started, so as to achieve the purpose of video playback.

After the mobile terminal receives the button message, the message processing function adds a response to the message in the message queue, judges whether the video format to be opened is legal, checks whether there is a video application running, if there is a video application running, before the end The application responds to the current button response, and at the same time handles whether there are other multimedia applications running, because it is necessary to ensure that the audio device and the video device are exclusive during the video playback process, and determine whether the video playback is currently the first priority Level, when the condition is met, start the video playback application. In the processing function, the button message is intercepted, and when the message is processed, the application for the video buffer is completed while the lower layer is notified to start the video playing application.

In summary, in the present invention, the mobile terminal uses resources to carry out reasonable control, and completes the message response between the upper and lower layers through thread concurrency and channel messages, so that it can ensure that the message is passed to the upper layer (or the upper layer) in the shortest time. The lower layer), the channel message can also ensure that the message will not be lost. In the process of application startup, the scheme of initializing the device without refreshing the screen and overlaying is adopted, and the drawing module completes the interface drawing. This method can effectively reduce the load on the processor. Priority The interface drawing is completed, and it can also respond to screen swiping and decoding in a very short time, so it can improve the user experience very well.
