Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a program playing method according to a first embodiment of the present invention is provided, where the program playing method is used to operate on a media playing box, and the method controls a first display window to play a program, obtains a target special effect according to a user behavior parameter, and controls a second display window stacked on the first display window to play a special effect program, so as to implement receiving a program and the target special effect at a target display terminal and perform corresponding display. The program playing method comprises the following steps:
101, controlling a first display window to play a program, and making the program played by the first display window visible. For example, an operating system is run on the media playing box, a first display window is created through the operating system, and the first display window is controlled to play a program, for example, the program stored on the program playing box, for example, when the media playing box is externally connected to a target display terminal, the media playing box is for example a sending card, the target display terminal is for example an LED display screen configured with a receiving card, and the sending card controls the content of the program played by the first display window to be visible on the screen of the LED display screen, that is, the viewer can view the content of the program played on the screen of the LED display screen.
In one embodiment, for example, an Android operating system is run on the media playing box, and the Android operating system controls the created first display window to play the program.
102 obtain user behavior parameters. For example, a sensor is arranged on a target display terminal connected with the outside of the media playing box, and the sensor acquires user behavior parameters and transmits the user behavior parameters to the media playing box; the user behavior parameters are user behavior data acquired by the sensor responding to the action of the user in real time and the media playing box converts the user behavior data into the user behavior parameters; the user is, for example, a viewer watching the content played by the target display terminal, for example, different user behavior parameters are obtained in response to different user actions, and thus, a plurality of user behavior parameters are obtained, for example, one user behavior parameter is obtained in response to one user action.
103, obtaining a target special effect according to the user behavior parameters. For example, a special effect algorithm function is stored in the media playing box, the special effect algorithm function is executed to obtain a target special effect according to the user behavior parameters, for example, a plurality of different user behavior parameters respectively correspond to different target special effects one by one, and the special effect algorithm function is executed to obtain a target special effect according to a user behavior parameter, where the user behavior parameter is the user behavior parameter obtained in step 102.
For example, a mapping relationship exists between the user behavior parameters and the target special effect, and the media playing box executes a special effect algorithm function to obtain the target special effect according to one user behavior parameter and the mapping relationship. For example, N different target special effects can be obtained by executing a special effect algorithm function by the media playing box, M (M is equal to or less than N) different user behavior parameters can be obtained in step 103, and one user behavior parameter corresponds to one target special effect according to a mapping relationship.
104, controlling a second display window stacked above the first display window to play the target special effect. Referring to step 101, for example, a media playing box is provided with a second display window stacked on the first display window, the Android operating system controls the second display window to play, and the target special effect is obtained in step 103, at this time, the target special effect played by the second display window is visible and partially or completely covers the program played by the first display window, so that the program played by the first display window is partially or completely invisible. For example, the media playing box is connected with an LED display screen with a receiving card, the LED display screen displays contents of two superimposed layers, the two superimposed layers respectively correspond to the first display window and the second display window, wherein the content displayed on the upper layer is a target special effect played by the second display window, and the content displayed on the lower layer is a program played by the first display window.
In one embodiment, for example, the second display window controlled by the media playing box completely covers the first display window controlled by the media playing box, and at this time, the target special effect played by the second display window is visible, and the program played by the first display window is invisible, that is, the viewer cannot view the content of the program played on the screen of the LED display screen.
In one embodiment, the second display window controlled by the media playing box partially covers the first display window controlled by the media playing box, when the second display window plays the target special effect, the target special effect played by the second display window is visible, and the program played by the first display window is partially visible, for example, the program played by the first display window controlled by the media playing box is partially visible on the screen of the LED display screen.
In one embodiment, referring to fig. 2, the method for making the program played in the first display window visible in step 101 is, for example: and controlling the second display window to be a transparent window and/or controlling the second display window to play a transparent special effect.

In an embodiment, referring to fig. 3, the obtaining of the user behavior parameter in step 102 includes: receiving user behavior data collected by a sensor associated with a target display terminal; and filtering the user behavior data to acquire the user behavior parameters.
In one embodiment, the sensor is, for example, electrically connected to the media playing box, the sensor is, for example, an ultrasonic sensor or a metal resistance strain gauge, the associated target display terminal is, for example, provided with the ultrasonic sensor in front of the target display terminal, and when the viewer makes a motion in the process of normally watching the content of the played program in front of the target display terminal, the ultrasonic sensor responds to the motion to obtain the user behavior data; the related target display terminal is, for example, a metal resistance strain gauge is embedded below the target display terminal, when a viewer acts in the process of normally watching the content of a program played by the viewer in front of the target display terminal, or when the viewer does not watch the program played by the target display terminal, the metal resistance strain gauge responds to the action to obtain user behavior data; the media player box receives user behavior data from, for example, a sensor, and performs mean filtering on the user behavior data to remove interference data and retain key useful behavior data, which is then converted into user behavior parameters that can be used to perform step 103.
In one embodiment, step 104 further comprises adjusting the property of the second display window, for example, in the process of controlling the second display window to play the target special effect. The attribute of the second display window includes at least one of a process of reducing or enlarging the size of the second display window relative to the size of the first display window, the size of the second display window, an offset amount of the second display relative to the first display window, an offset angle of the second display window relative to the second display window, an offset angular velocity of the second display window relative to the first display window, and the like.
In one embodiment, for example, the target effect obtained in step 103 includes adjusting the property of the second display window to change the position of the second display window relative to the first display window and/or the size of the second display window.

The program is, for example, an externally input program, and the special effect algorithm function is executed, for example, the user behavior parameters obtained in step 102 are substituted into the special effect algorithm function to obtain the target special effect; for example, the upper computer issues a program and a special effect algorithm function, the media playing box is connected with the upper computer to receive and store the program and the special effect algorithm function to the volatile memory, the upper computer is, for example, a remote server, an upper computer PC terminal or an onboard memory, and the media playing box acquires an external input program and the special effect algorithm function through network connection, data line connection or a mode of directly reading the onboard memory.
In one embodiment, an externally input program is received and stored; for example, in step 102, user behavior parameters are acquired and uploaded to an upper computer, and the upper computer executes an algorithm special effect function to obtain a target special effect according to the user behavior parameters and issues the target special effect so as to obtain the target special effect.
In one embodiment, receiving and storing the external input program and the special effect algorithm function associated with the external input program further comprises receiving and storing a transparent special effect, for example, controlling a second display window stacked above a first display window to play the transparent special effect when the first display window is controlled to play the external input program.
In an embodiment, for example, in the step 102, the media playing box obtains a plurality of user behavior parameters, and for example, in the step 103, the media playing box obtains a plurality of target special effects according to the plurality of user behavior parameters, and then the second display window plays the plurality of target special effects according to a set sequence, or the second display window simultaneously plays the plurality of target special effects.
In one embodiment, the program playing method further includes outputting the program and the target special effect to a target display terminal.
In one embodiment, for example, when the media playing box does not obtain the user behavior parameters, the media playing box issues the program to a downstream device, for example, an LED display screen with a receiving card, the LED display screen plays the program, and the viewer can see the content of the program.
