Example one

As shown in fig. 1, the present embodiment provides a method for saving energy in an audio mode of a set-top box, including the following steps:

and S110, when the set top box is detected to enter the sound mode, adjusting the working frequency of the CPU to be a first frequency.

In this step, the sound mode refers to that the set-top box starts the sound function, and other functions are in a standby state or a non-started state. In this step, the first frequency described in this embodiment refers to an operating frequency at which the CPU is at the lowest power consumption when the sound mode and other functions of the set-top box are in a standby state or in an unopened state.

And S120, judging whether an application opening instruction is received.

And S130, if so, judging whether the application is in a preset sound mode white list.

The application starting instruction in the step is an instruction initiated by a user to the set top box, in the sound mode, the set top box only allows the instructions to control applications in the sound mode, and the applications in the white list are applications enabling the sound mode to be normally used, and include but are not limited to a bluetooth client, a loudspeaker and the like.

The receiving mode of the open application instruction may include but is not limited to: the method comprises the steps of receiving a key instruction, receiving a gesture instruction, receiving a startup and shutdown triggering instruction and/or receiving a voice instruction, wherein all the instructions can adopt the instruction input mode. The step of receiving the on-off trigger instruction is that the set top box with the sound box is triggered to enter a set top box mode when a television connected with the set top box is turned on, and the set top box with the sound box is triggered to enter the sound box mode when the television connected with the set top box is turned off.

And S140, if the application is not in the white list, intercepting the application opening instruction.

And intercepting the application starting instruction when the instruction initiated by the user is not used for controlling the sound, such as adjusting a television channel, switching an interface and the like.

S150, if the CPU is in the white list, enabling the application, and adjusting the working frequency of the CPU to a second frequency.

After the application is started, the work load of the CPU is increased, and the CPU adjusts the work frequency to a second frequency through the frequency modulation function. When the application, such as a bluetooth function, is enabled, the power consumption of the CPU is increased, the second frequency in this step refers to a working frequency at which the lowest power consumption of the CPU is achieved when the application in the audio mode is normally operated, the power consumption of the CPU at the second frequency is higher than the power consumption of the CPU at the first frequency, and the second frequency has different values according to a change of the application started in the audio mode.

In the above-mentioned step, the step of,

Example two

As shown in fig. 2, in this embodiment, on the basis of the above embodiment, a step is added in which the set-top box in the audio mode adjusts the CPU power when receiving an instruction initiated by the external device, such as an instruction of a remote controller. The set top box does not influence the use experience of the user under the condition of lowest power consumption. The method comprises the following steps:

s201, when the set top box is detected to enter the sound mode, the working frequency of the CPU is adjusted to be a first frequency.

In this step, the sound mode refers to that the set-top box starts the sound function, and other functions are in a standby state or a non-started state. For example, when the set-top box is in the sound function mode, an external television can also work normally. In this step, the first frequency described in this embodiment refers to an operating frequency at which the CPU is at the lowest power consumption when the set-top box is in the audio mode and other functions are in the standby state or the non-on state.

S202, judging whether an application opening instruction is received.

The application opening instruction in the step includes a control instruction for any application program in the set top box, and in order to avoid that the opened application is not related to the sound mode, whether the application instruction in the step is an instruction for controlling the sound mode needs to be judged.

S203, if so, judging whether the application is in a preset sound mode white list.

And S204, if the application is not in the white list, intercepting the application opening instruction.

S205, if the CPU is in the white list, the application is allowed to be started, and the working frequency of the CPU is adjusted to a second frequency.

After the application is started, the work load of the CPU is increased, and the CPU adjusts the work frequency to a second frequency through the frequency modulation function. When the application, such as a bluetooth function, is enabled, the power consumption of the CPU is increased, the second frequency in this step refers to a working frequency at which the CPU is at the lowest power consumption when the application in the audio mode can normally work, the power consumption of the CPU at the second frequency is higher than that of the CPU at the first frequency, and the second frequency has different values according to the difference of the applications started in the audio mode. The second frequency is greater than the first frequency in this embodiment.

S206, judging whether an application closing instruction is received.

In step S205, the operating frequency of the CPU is adjusted to the second frequency, and after the application is used, the CPU correspondingly reduces the load of the CPU according to the received close instruction, and automatically adjusts the frequency to the first frequency according to the load change.

And S207, if an application closing instruction is received, closing the application, and adjusting the working frequency of the CPU to a first frequency.

In another alternative embodiment, as shown in fig. 3, S205 may be followed by:

and S208, judging whether the set top box receives an application control instruction.

In this step, the external device may send an application control instruction to the set-top box, for example, an instruction sent by the remote controller to the set-top box, may be a control instruction in the audio mode, or may be a function control instruction to the external device such as a television, and therefore, the input control instruction cannot be directly disabled, and the received input control instruction needs to be determined.

And S209, if so, judging whether the application control command is an audio mode command.

The sound mode command in this step refers to a control command input by the peripheral input device, and the purpose of the control command is to control a function or an application in the sound mode.

And S210, if so, reporting the application control instruction to a CPU.

In this step, the main control chip executes an operation according to the application control instruction, and when the application changes, the CPU load also changes, so in an alternative embodiment, this step may further include: determining an opened application based on the application control instruction; adjusting a value of the second frequency based on the turned-on application.

S211, if not, intercepting the application control command.

The embodiment increases the frequency of the CPU which is correspondingly adjusted when the application of the sound mode is started and closed, so that the CPU is always in the state of not influencing the normal use of the sound mode and having the lowest power consumption. Meanwhile, the embodiment closes all irrelevant applications by closing the function of the set top box for outputting outwards, thereby reducing the power consumption of the CPU.

EXAMPLE III

As shown in fig. 4, in this embodiment, on the basis of the above embodiment, a step of turning off the peripheral is added after the set-top box enters the audio mode, so that the CPU of the set-top box further reduces power consumption. The method comprises the following specific steps:

s301, after the set top box is detected to enter the sound mode, the output function of the set top box irrelevant to the sound mode is closed, and the working frequency of the CPU is adjusted to a first frequency.

In the foregoing embodiment, the sound mode refers to that the set-top box turns on the sound function, and other functions are in a standby state or in an unopened state, for example, when the set-top box is in the sound function mode, the function of the external television is in the standby state, and has a certain CPU power consumption.

Because the set-top box is in the audio mode, other functions of the set-top box are not needed, and in order to avoid that the set-top box main control chip controls various external devices irrelevant to the audio mode through the output driver, and thus the CPU has an extra operation load, in this embodiment, after the set-top box enters the audio mode, the output drivers connected with other external devices need to be completely turned off, so that the CPU of the main control chip does not need to load the operation pressure of the external devices.

In this step, the output function of the set-top box unrelated to the audio mode refers to a function of receiving an instruction output from the set-top box and executing the corresponding instruction, and implementing these output functions includes: the device connected with the set-top box, the interface of the set-top box and/or the functional module of the set-top box. Such as an audio/video output driver, a video decoding module, a graphic processing module, etc. of the set-top box, the video decoding module is used for receiving channel program signals of the set-top box and decoding audio streams and video streams to enable the television to execute corresponding audio and video playing functions, and the functional modules all realize output functions unrelated to the sound mode of the set-top box.

In this step, turning off all output functions of the set-top box that are not related to the audio mode specifically includes the following steps:

and closing output interfaces which are irrelevant to the sound mode of the set-top box, such as a high-definition multimedia interface (HDMI), a Composite Video Broadcast Signal (CVBS) interface, a Serial Advanced Technology Attachment (SATA) interface and/or a Universal Serial Bus (USB) interface of the disabled set-top box.

And/or

And turning off functional modules irrelevant to the sound mode of the set top box, such as a modulation and demodulation module, a television audio and video output module, a television audio and video decoding module and/or a graphic processing module of the set top box. The above steps may be performed simultaneously or one of them may be selected to turn off all output functions of the set-top box that are not related to the sound mode.

After the peripheral controllers irrelevant to the service required by the user are closed, the first frequency refers to the working frequency of the CPU in the lowest power consumption mode when the set top box is in the sound mode and all the peripheral controllers irrelevant to the sound mode are closed.

S302, judging whether an application opening instruction is received.

And S303, if so, judging whether the application is in a preset sound mode white list.

S304, if the application is not in the white list, intercepting the application opening instruction.

S305, if the CPU is in the white list, enabling the application, and adjusting the working frequency of the CPU to a second frequency.

Optionally, after step S305, the method further includes a step of restoring the set-top box from the energy-saving audio mode to the set-top box mode used normally, specifically as follows:

judging whether a set-top box mode instruction is received or not, and if so, adjusting the working frequency of the CPU from the second frequency to a third frequency;

the third frequency refers to the operating frequency of the CPU when the set-top box is in a normal operating mode, capable of supporting all set-top box mode functions such as cable tv, music, games and/or any network applications.

After the working frequency of the CPU is adjusted to the third frequency, the method further comprises the following steps: and closing the white list function, and executing the received application opening instruction.

Optionally, after the CPU adjusts to the third frequency, the method further includes: and restarting the output function of the set top box.

In this embodiment, the CPU is adjusted to the frequency that can only support the audio mode, so that the audio mode can normally operate and other functions are all turned off, and the CPU of the main control chip does not need to load the operating pressure of the peripheral device, thereby achieving the effect of further reducing the power consumption of the CPU.
