Detailed Description
The inventor finds out through research that: with the development of internet technology, electronic devices providing multimedia information are increasing, but in current applications, when video played by the electronic device a is switched from being provided by the electronic device B to being provided by the electronic device C, the electronic device C needs to be manually operated. As shown in fig. 1, in the control system, a video played by a smart tv 1 (which may be regarded as a first electronic device) may be provided by a set-top box 2 and a dedicated computer Stick PC3 (which may be regarded as a second electronic device), the Stick PC3 may be connected to the smart tv through a USB interface (which may be regarded as a first interface), and a video currently being played by the smart tv 1 is provided by the set-top box 2, and the video provided by the set-top box 2 is controlled by a remote controller 4 (which may be regarded as a third electronic device) to perform channel switching.
When the video played by the intelligent television 1 is switched from being provided by the set top box 2 to being provided by the Stick PC3, the Stick PC3 needs to be manually started, and when the video played by the intelligent television 1 is provided by the Stick PC3 and then is provided by the set top box 2, the Stick PC3 needs to be manually closed, so that the operation intelligence is reduced. Therefore, the embodiment of the invention provides a control method, which can automatically switch the state of a second electronic device (such as a Stick PC) based on the signal input and output conditions of a first electronic device (such as a smart television), thereby improving the operation intelligence.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
Referring to fig. 2, a flowchart of a control method applied to the first electronic device in fig. 1 is shown, for automatically switching a state of the second electronic device based on signal input and output conditions of the first electronic device, so as to improve operation intelligence. Specifically, the control method shown in fig. 2 may include the following steps:
201: and acquiring the signal input and output condition of the first electronic equipment. Wherein the signal input and output condition comprises: the first electronic device receives the resource from the first interface, and the second electronic device receives the resource from the second interface.
Taking the above fig. 1 as an example, one possible case of signal input is: whether the multimedia file received by the smart tv 1 as the first electronic device is provided by the Stick PC3 as the second electronic device or the set-top box controlled by the remote controller 4 as the third electronic device. One possible case in the case of signal outputs is: the smart tv as the first electronic device supplies power to the Stick PC as the second electronic device through the USB interface (first interface).
202: and when the signal input and output condition indicates that the signal input or the signal output of the first electronic equipment is changed, indicating the second electronic equipment to switch the state, wherein the power consumption of the second electronic equipment is changed after the second electronic equipment switches the state.
When the signal input and output condition indicates that the signal input of the first electronic equipment changes, the resource provider of the first electronic equipment is about to be changed, and when the signal input and output condition indicates that the signal output of the first electronic equipment changes, the power support of the first electronic equipment to the second electronic equipment possibly changes.
For example, when the signal input/output condition indicates that the signal input or the signal output of the first electronic device changes, the first electronic device may send a control instruction to the second electronic device to instruct the second electronic device to perform state switching. Whether the signal input or the signal output of the first electronic device changes may be determined by changing the signal input source of the first electronic device or based on the signal transmission condition on the first interface, and the following description will take the control system shown in fig. 1 as an example.
In the control system shown in fig. 1, a remote controller 4 as a third electronic device sends a video switching instruction to the smart television 1 as a first electronic device, and displays a video switching interface on the interface of the smart television 1, as shown in fig. 3. When the yes option in the video switching interface is selected to indicate that the video played by the smart television 1 is switched, and the signal input/output condition of the smart television 1 indicates that the signal input source of the smart television is switched from being provided by other equipment (such as the set-top box 2) controlled by the remote controller 4 to being provided by the Stick PC, as shown in fig. 4, the smart television 1 sends a control instruction to the Stick PC3 through the first interface, and the Stick PC3 switches from the sleep state to the wake-up state to provide the video to the smart television 1 through the first interface after receiving the control instruction (the arrow indicates that the Stick PC provides the video to the smart television).
Or before the Stick PC3 provides no video to the smart tv 1, the Stick PC3 is in the off state, and when the smart tv 1 needs the Stick PC3 as a signal input source, the smart tv 1 sends a control instruction to the Stick PC3 through the first interface and supplies power to the Stick PC3 through the first interface, so that the Stick PC3 is powered on after receiving the control instruction and is switched from the off state to the on state to provide the video to the smart tv 1 through the first interface.
If the video played by the smart tv 1 is switched again, as shown in fig. 5, the signal input source of the smart tv is switched from being provided by the Stick PC3 to being provided by the set-top box 2, the smart tv will again send a control command to the Stick PC3 through the first interface to instruct the Stick PC to switch from the wake-up state to the sleep state or instruct the power-on state to switch to the power-off state.
When a control command is sent to the Stick PC3 through the first interface to instruct the Stick PC to switch from the on state to the off state, the smart television stops supplying power to the Stick PC3 through the first interface, so that the Stick PC3 automatically switches from the on state to the off state.
From the above video switching process, it can be known that: under the condition that the Stick PC is used as a signal input source of the intelligent television, the Stick PC provides video to the intelligent television through the first interface, and the intelligent television also provides power to the Stick PC through the first interface; and under the condition that the Stick PC is not a signal input source of the intelligent television, the Stick PC does not provide video for the intelligent television through the first interface any more, and the intelligent television does not supply power for the Stick PC through the first interface any more, so that the control for switching the state of the second electronic equipment can also indicate the second electronic equipment to be switched from the wake-up state to the sleep state or indicate the second electronic equipment to be switched from the power-on state to the power-off state when the signal input and output condition indicates that no multimedia signal is input into the first interface or no electric signal is output from the first interface.
In order to instruct the second electronic device to perform state switching, the first electronic device is configured in a BIOS (Basic Input Output System), so that the first electronic device can support a wake-up function through the first interface, and thus the first electronic device can send a control instruction through the first interface to wake up the second electronic device. After the second electronic device is switched from the sleep state to the wake state or from the power-off state to the power-on state, the second electronic device starts to work normally, so that the second electronic device is switched from the low-power-consumption state to the high-power-consumption state, that is, the power consumption of the second electronic device is changed from low power consumption to high power consumption.
According to the technical scheme, when the signal input and output condition indicates that the signal input or the signal output of the first electronic equipment changes, the second electronic equipment connected with the first electronic equipment through the first interface is indicated to switch the state, so that the state of the other electronic equipment is automatically switched based on the signal input and output condition of one electronic equipment, and the power consumption of the corresponding electronic equipment changes after the state is switched.
For example, the first electronic device may be a smart television, the second electronic device is a Stick PC connected to the smart television through a USB interface, and when the signal input/output condition of the smart television indicates that the signal input of the smart television is provided by the Stick PC, the smart television may instruct the Stick PC to switch from a sleep state to a wake state, thereby implementing automatic switching of states and improving operation intelligence.
Corresponding to the above method embodiment, an embodiment of the present invention further provides a control method based on the control system shown in fig. 1 and applied to a second electronic device, where a flowchart of the control method is shown in fig. 6, and the control method may include the following steps:
601: and acquiring the signal input and output condition of the second electronic equipment. In the embodiment of the present invention, the signal input/output condition refers to whether the second electronic device receives information sent by the first electronic device through the first interface. As shown in fig. 4, when the signal input source of the smart tv 1 as the first electronic device is switched from being provided by the set-top box to being provided by the Stick PC as the second electronic device, the smart tv 1 supplies power to the Stick PC through the first interface, which means that the second electronic device receives information transmitted by the first electronic device through the first interface.
602: and when the signal input and output condition indicates that the signal input of the second electronic equipment is changed, controlling the second electronic equipment to switch the state, wherein the power consumption of the second electronic equipment is changed after the state of the second electronic equipment is switched. In the embodiment of the present invention, possible ways to control the second electronic device to perform state switching include, but are not limited to, the following ways:
one way is that: and when the signal input and output condition indicates that a signal is input in the first interface and the path of the signal input is from the first electronic equipment to the second electronic equipment, controlling the second electronic equipment to be switched from the dormant state to the awakening state.
The other mode is as follows: and when the signal input and output condition indicates that no signal is input in the first interface, controlling the second electronic equipment to be switched from the awakening state to the dormant state or controlling the second electronic equipment to be switched from the power-on state to the power-off state.
In the following description with reference to the video switching process of the control system shown in fig. 4 and 5, when the signal input source of the smart tv 1 in fig. 4 is switched from other devices (e.g. the set-top box 2) controlled by the remote controller 4 to the click PC for providing, as shown in fig. 4, the remote controller 4 no longer controls the set-top box 2 in fig. 4 (corresponding to the dotted line in fig. 4), and the smart tv 1 sends a control instruction to the click PC3 through the first interface, at this time, the signal input/output condition of the click PC indicates that there is a signal input in the first interface, and the path of the signal input is from the smart tv to the click PC, so that the second electronic device can be controlled from the sleep state to the wake state.
As can be seen from fig. 5, the signal input source of the smart tv 1 is switched from being provided by the Stick PC to being provided by the set-top box, and at this time, the smart tv 1 does not supply power to the Stick PC through the first interface any more, which means that there is no signal input in the first interface, and at this time, the second electronic device can be controlled to switch from the awake state to the sleep state or controlled to switch from the power-on state to the power-off state.
According to the technical scheme, when the signal input and output condition indicates that the signal input of the second electronic equipment changes, the second electronic equipment connected with the first electronic equipment through the first interface is controlled to switch the state, so that the automatic switching of the state is realized, and the power consumption of the corresponding electronic equipment changes after the state switching.
For example, the first electronic device may be a smart television, the second electronic device may be a Stick PC connected to the smart television via a USB interface, and when the signal input/output condition of the smart television changes, the Stick PC automatically switches states, thereby improving operation intelligence.
While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present invention is not limited by the illustrated ordering of acts, as some steps may occur in other orders or concurrently with other steps in accordance with the invention. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required by the invention.
Corresponding to the method embodiment shown in fig. 2, an embodiment of the present invention further provides a control device, which is applied to a first electronic device, where the first electronic device is connected to a second electronic device through a first interface, and the first electronic device is controllable by a third electronic device. The structure of the control device is shown in fig. 7, and may include: a first acquisition unit 11 and an indication unit 12.
The first acquiring unit 11 is configured to acquire a signal input/output condition of the first electronic device. Wherein the signal input and output condition comprises: the first electronic device receives the resource from the first interface, and the second electronic device receives the resource from the second interface.
Taking the above fig. 1 as an example, one possible case of signal input is: whether the multimedia file received by the smart tv 1 as the first electronic device is provided by the Stick PC3 as the second electronic device or the set-top box controlled by the remote controller 4 as the third electronic device. One possible case in the case of signal outputs is: the smart tv as the first electronic device supplies power to the Stick PC as the second electronic device through the USB interface (first interface).
And the indicating unit 12 is configured to indicate the second electronic device to perform state switching when the signal input/output condition indicates that the signal input or the signal output of the first electronic device changes, where after the state switching is performed on the second electronic device, power consumption of the second electronic device changes.
When the signal input/output condition indicates that the signal input of the first electronic device changes, it indicates that the first electronic device is about to change the resource provider, and when the signal input/output condition indicates that the signal output of the first electronic device changes, it indicates that the power support of the first electronic device to the second electronic device may change.
For example, when the signal input/output condition indicates that the signal input or the signal output of the first electronic device changes, the indicating unit 12 may send a control instruction to the second electronic device to instruct the second electronic device to perform state switching. Whether the signal input or the signal output of the first electronic device changes or not can be determined by changing the signal input source of the first electronic device or based on the signal transmission condition on the first interface, and several state switching conditions are described below.
One situation is: the instruction unit 12 instructs the second electronic device to switch from the sleep state to the awake state when the signal input output condition indicates that the signal input source of the first electronic device is switched from being provided by the other device controlled by the third electronic device to being provided by the second electronic device, and the instruction unit 12 instructs the second electronic device to switch from the awake state to the sleep state when the signal input output condition indicates that the signal input source is switched from being provided by the second electronic device to being provided by the other device controlled by the third electronic device.
The other situation is that: the instruction unit 12 instructs the second electronic device to switch from the power-off state to the power-on state when the signal input/output condition indicates that the signal input source is switched from being provided by the other device controlled by the third electronic device to being provided by the second electronic device, and instructs the second electronic device to switch from the power-on state to the power-off state when the signal input/output condition indicates that the signal input source is switched from being provided by the second electronic device to being provided by the other device controlled by the third electronic device.
Yet another situation is: when the signal input/output condition indicates that there is no multimedia signal input in the first interface or no electrical signal output in the first interface, the indicating unit 12 indicates the second electronic device to switch from the wake-up state to the sleep state or indicates the second electronic device to switch from the power-on state to the power-off state.
According to the technical scheme, when the signal input and output condition indicates that the signal input or the signal output of the first electronic equipment changes, the second electronic equipment connected with the first electronic equipment through the first interface is indicated to switch the state, so that the state of the other electronic equipment is automatically switched based on the signal input and output condition of one electronic equipment, and the power consumption of the corresponding electronic equipment changes after the state is switched.
For example, the first electronic device may be a smart television, the second electronic device is a Stick PC connected to the smart television through a USB interface, and when the signal input/output condition of the smart television indicates that the signal input of the smart television is provided by the Stick PC, the smart television may instruct the Stick PC to switch from a sleep state to a wake state, thereby implementing automatic switching of states and improving operation intelligence.
Corresponding to the method embodiment shown in fig. 6, an embodiment of the present invention further provides a control device, which is applied to a second electronic device, where the second electronic device is connected to a first electronic device through a first interface, and the first electronic device is controllable by a third electronic device. The structure of the control device is shown in fig. 8, and may include: a second acquisition unit 21 and a control unit 22.
And a second acquiring unit 21, configured to acquire a signal input/output condition of the second electronic device.
