detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a terminal power information prompting method.

Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of a method for prompting a battery power information according to the present invention.

In this embodiment, the terminal power information prompting method includes:

Step S10: acquiring the number of audio and video playback applications running in the terminal, the power consumption parameters of the respective audio and video playback applications, and the remaining power of the terminal;

The smart TV and the terminal are connected by means of WiFi or Bluetooth. After the smart TV establishes a connection with the terminal, the smart TV acquires the number of audio and video playback applications running in the terminal, and each audio and video. The power consumption parameter of the application and the remaining power of the terminal are played. The terminal includes, but is not limited to, a smart phone, a tablet computer, and a personal computer. For example, when the smart TV establishes a connection with the smart phone, the remaining power of the acquired smart phone is 5000 mA.

Further, the step S10 includes:

Obtaining the number of audio and video playing applications running in the terminal and the remaining power of the terminal, and acquiring identification information of the running audio and video playing application;

Obtaining a decoding mode of the audio and video playing application according to the identifier information, and obtaining a power consumption parameter of the audio and video playing application according to the decoding manner.

The smart TV acquires the number of audio and video playback applications that are running in the terminal, and obtains identification information of the running audio and video playback application, and determines the audio and video playback application according to the identification information. The type of program. When the smart TV acquires the same identification information, it indicates that there are multiple applications in the terminal, for example, three cool dog music in the smart phone are running at the same time. When the smart TV detects that the number of audio and video playback applications running in the smart phone is three, the smart television acquires identification information of an audio and video playback application that is running in the terminal, such as obtaining The identification information is Video_Pakg_Name(x1)=iqiyi, Video_Pakg_Name(x2)=youku, Video_Pakg_Name(x3)=sohu. The smart TV is via ASCII (American Standard Code for Information Interchange, the US Standard Information Exchange Code) obtains the application package name of the audio and video playback application, that is, the package name of the application is youku, iqiyi, and sohu.

The smart TV obtains the decoding mode of the application according to the identification information of the audio and video playing application running in the terminal, and obtains the power consumption parameter of the audio and video playing application according to the decoding mode. In this embodiment, the unit of the power consumption parameter is mA/s (milliamps per second), which means that the power consumption is 0.1 mA in one second. If the smart TV obtains the power consumption parameter corresponding to the userku decoding mode: youku :Batt_Play_Var(x)=0.2 mA/s, Batt_Audio _Var(x)=0.2 mA/s, ie the power consumption parameter of yourku video soft decoding mode is 0.1 mA/s, audio soft decoding mode power consumption parameter is 0.1 mA / s, video hard decoding mode power consumption parameter is 0.2 mA / s, audio hard decoding mode power consumption parameter is 0.2 mA/s; obtaining the power consumption parameter corresponding to the iqiyi decoding mode is: Batt_Play_Var(x)=0.1 mA/s, Batt_Audio_Var(x)=0.2 mA/s, that is, the power consumption parameter of the iqiyi video soft decoding mode is 0.1 mA/s, the power consumption parameter of the audio soft decoding mode is 0.1 mA/s, and the power consumption parameter of the video hard decoding mode is 0.2 mA/s. mA/s, the power consumption parameter of the audio hard decoding mode is 0.2 mA/s; the power consumption parameter corresponding to the sohu decoding mode is: Batt_Play_Var(x)=0.1 mA/s, Batt_Audio _Var(x)=0.2 mA/s, that is, the power consumption parameter of the sohu video soft decoding mode is 0.1 mA/s, and the power consumption parameter of the audio soft decoding mode is 0.1. mA/s, the power consumption parameter of the video hard decoding mode is 0.2 mA/s, and the power consumption parameter of the audio hard decoding mode is 0.2 mA/s.

Step S20, when at least two audio and video playing applications are running in the terminal, according to a decoding mode combining soft decoding and hard decoding, the number of the audio and video playing applications, and the audio and video playing. The power consumption parameter of the application calculates the amount of power required by the audio and video playback application;

When the smart TV detects that at least two audio and video playing applications are running in the terminal, the smart television is based on a combination of soft decoding and hard decoding, and the audio and video playing application The number and the power consumption parameter of the audio and video playback application calculate the amount of power required by the audio and video playback application. The soft decoding power consumption parameter is smaller than the hard decoding power consumption parameter, because the hard decoding requires hardware line support and chip power supply, and the power consumption parameter is large, and the soft decoding does not require hardware power supply. The power consumption parameters are small. The terminal configures different decoding modes according to different application programs, and different decoding modes correspond to different power consumption parameters. The power consumption parameter is the amount of power consumed per unit time, such as the smart TV passing through its CPU (Central Processing When the decoding mode of the video player of the smart phone is 1, the decoding mode of the video player of the smart phone is soft decoding, and the decoding mode of the video player of the smart phone is At 2 o'clock, the decoding mode of the video player representing the smartphone is hard decoding. If the smart TV obtains the video soft decoding power consumption parameter of a video player in the smart phone is 0.1 mA/s, the audio soft decoding power consumption parameter is 0.1 mA/s, and the video hard decoding power consumption parameter is 0.2mA/s, the audio hard decoding power consumption parameter is 0.2mA/s. The specific size of the power consumption parameter is determined according to a specific case, and is not limited to 0.1 mA/s and 0.2 mA/s in the present embodiment.

In this embodiment, the smart phone is in a multi-application scenario, that is, the smart phone runs multiple applications at the same time, for example, when you run Youku, iQiyi iqiyi, and Sohu sohu at the same time, the smart phone The screen of the TV will be divided into three parts, showing the pictures that youku, iqiyi and sohu want to display. Different applications have different decoding methods. The multiple audio and video playback applications running simultaneously in the smart phone generally do not use the hard decoding mode, because the hard decoding mode corresponds to only one circuit and can only be used by one audio and video playback application. Generally, an audio and video playback application uses hard decoding, and another audio and video playback application uses soft decoding. The specific situation is not limited, as long as multiple audio and video playback applications can be run simultaneously.

Further, the step S20 includes:

Obtaining a task time of the audio and video playing application when there are at least two audio and video playing applications running in the terminal;

Calculating the amount of power required by the audio and video playback application according to the number of audio and video playback applications, the task time of the audio and video playback application, and the power consumption parameters of the audio and video playback application.

And when the smart TV determines that at least two audio and video playing applications are running in the terminal, acquiring a task time of the audio and video playing application. The smart TV calculates the required audio and video playback application according to the number of the audio and video playback application, the task time of the audio and video playback application, and the power consumption parameters of the respective audio and video playback applications. Electricity. For example, when the smart TV displays the picture of the song "Fireworks" played by the Youku on the left side of the screen, the required task time is Time. Total(x)=300s (seconds), and when the audio of the youku is turned off, the youku adopts the video hard decoding mode, so the video soft decoding consumes the power parameter 0, and because the audio is turned off, the audio hard decoding mode The power consumption parameters of the power consumption parameter and the audio soft decoding mode are all 0, that is, Batt_Play_Var(x)=0.2 mA/s, Batt_Audio _Var(x)=0, so the power consumption parameter of the hard decoding method of the Youku video is 0.2. mA/s; when the smart TV displays the picture of the TV series "Hua Qian Bone" played by the iqiyi in the middle of its screen, the required task time is Time Total(x)=3000s, the audio of the iqiyi is turned off, and the iqiyi adopts the video soft decoding mode, so the power consumption parameter of the video soft decoding mode is 0, and because the audio is turned off, the power consumption parameter and audio of the audio hard decoding mode are The power consumption parameter of the soft decoding mode is 0, that is, Batt_Play_Var(x)=0.1 mA/s, Batt_Audio _Var(x) = 0, so the power consumption parameter of the iqiyi video hard decoding mode is 0.1 mA/s; when the smart TV displays the black picture of the sohu on the right side of its screen, that is, when listening to the dubbing of the movie "Catch the Demon", the required task time is Time Total(x)=20000s, the video player of the sohu is closed, the sohu adopts audio soft decoding mode, so the power consumption parameter of the audio hard decoding mode is 0, and because the video player is turned off, the video hard decoding mode consumes The power consumption parameters of the electrical parameters and the video soft decoding mode are all 0, that is, Batt_Play_Var(x)=0, Batt_Audio _Var(x)=0.1 mA/s, so the sohu audio soft decoding power consumption parameter is 0.1 mA/s. The smart TV calculates the required power of each audio and video playing application according to the power consumption parameter and the task time of each audio and video playing application, that is, the required power of the youku is Prog_Batt_Total(x1)=Batt_Play_Var(x)* 300=60mA; the required power of the iqiyi is Prog_Batt_Total(x2)= Batt_Play_Var(x)*3000=300mA; the Sohu required power is Prog_Batt_Total(x3)= Batt_Audio _Var(x)*20000=2000 mA.

In step S30, the required power of the audio and video playing application is compared with the remaining power of the terminal to obtain a comparison result, and the first prompt information is output according to the comparison result to prompt the user to use the remaining power.

When the smart TV calculates the required power of the respective audio and video playing applications, comparing the sum of the power required by the respective audio and video playing applications with the remaining power of the terminal, and obtaining a comparison result, according to the The comparison result outputs the first prompt information to prompt the user to use the remaining power. When the comparison result indicates that the sum of the required power amounts of the respective audio and video playing applications is greater than or equal to the remaining power of the terminal, the smart television outputs the first prompt information, prompting the user to charge the terminal. When the comparison result indicates that the sum of the required power amounts of the respective audio and video playing applications is less than the remaining power of the terminal, the smart television outputs the first prompt information, prompting the user to play in the respective audio and video. The terminal does not need to be charged during the application task time. Further, the smart TV may further display, on the screen, the power required by the audio and video playing application that the terminal is running and the remaining power of the terminal, for the user to play the application according to the audio and video. Estimating the amount of power required by the program and the remaining capacity of the terminal, and/or transmitting the amount of power required by the audio and video playback application and the remaining power of the terminal to the terminal to The terminal is configured to display on its screen the amount of power required by the audio and video playback application and the remaining power of the terminal. If the smart TV determines that the sum of the required powers of the three applications of the youku, iqiyi, and sohu is less than the remaining power, displaying the youku, iqiyi, and sohu in the smart phone in the screen thereof. a sum of power required by the application, and a remaining power of the smart phone, the user knowing that the remaining power can support the youku, iqiyi, and/or according to the power information displayed by the smart TV and/or the smart phone The sohu playing task does not need to charge the smart phone during the completion of the play tasks of the youku, iqiyi, and sohu.

In this embodiment, when at least two audio and video playing applications are running in the terminal, the number of the audio and video playing applications and the respective audio and video playing applications are obtained according to a decoding manner combining soft decoding and hard decoding. The power consumption parameter of the program calculates the power required by the audio and video playback application; compares the power required by the audio and video playback application with the obtained remaining power of the terminal, and obtains a comparison result, which is output according to the comparison result. The first prompt information is used to prompt the user to use the remaining power. The task of automatically prompting the current power in the user terminal to complete the current multiple application tasks is avoided, and the user needs to perform a series of cumbersome operations to estimate the running time of the remaining power in the terminal, thereby improving the user experience.

If the smart TV obtains a total power of the smart phone of 10000 mA, the remaining power of the smart phone is 5000 mA, that is, the current remaining power of the smart phone is Stay_Electr (x1)=50, that is, the remaining of the smart phone. The amount of electricity is 50% of the total amount of electricity.

The soft decoding power consumption parameter is smaller than the hard decoding power consumption parameter, because the hard decoding requires hardware line support and chip power supply, and the power consumption parameter is large, and the soft decoding does not require hardware power supply. The power consumption parameters are small. The terminal configures different decoding modes according to different application programs, and different decoding modes correspond to different power consumption parameters. The power consumption parameter is the amount of power consumed per unit time, such as the smart TV passing through its CPU (Central Processing When the decoding mode of the video player of the smart phone is 1, the decoding mode of the video player of the smart phone is soft decoding, and the decoding mode of the video player of the smart phone is At 2 o'clock, the decoding mode of the video player representing a video player in the smartphone is hard decoding.
