Problems solved by technology

[0004] In this context, when the Stick PC is connected to the TV and the current TV is playing the video transmitted by the set-top box, if you want to switch to playing the video transmitted by the Stick PC, you must first turn on the Stick PC, and then use the remote control to input the signal of the TV. The source is switched to the Stick PC; similarly, if the signal input source is switched from the Stick PC to the set-top box again, the Stick PC needs to be further manually turned off, and this operation of manually controlling the Stick PC during the switching process is inconvenient and reduces the intelligence of the operation

Embodiment Construction

[0048] The inventor found through research that: with the development of Internet technology, there are more and more electronic devices that provide multimedia information, but in current applications, when the video played by electronic device A is switched from electronic device B to electronic device C, it is necessary to The electronic device C is manually operated. Such as figure 1 As shown in the control system, the video played by the smart TV 1 (which can be regarded as the first electronic device) can be played by the set-top box 2 and the exclusive computer Stick PC3 (which can be regarded as the second electronic device), and the Stick PC3 can be connected through the USB interface (which can be regarded as the second electronic device). One interface) is connected to the smart TV, and the 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 can be ...

Abstract

The present invention provides a control method, device and system, which acquires the signal input and output conditions of the first electronic device, and when the signal input and output conditions indicate that the signal input or signal output of the first electronic device changes, it indicates the The state switching of the second electronic device connected through the first interface realizes automatic switching of the state of another electronic device based on the signal input and output of one electronic device, and the power consumption of the corresponding electronic device changes after the state switching. For example, the above-mentioned first electronic device can be a smart TV, and the second electronic device is a Stick PC connected to the smart TV through a USB interface. When the signal input and output conditions of the smart TV show that the signal input of the smart TV is provided by the Stick PC, the smart TV Then it can instruct the Stick PC to switch from the sleep state to the wake-up state, realize the automatic switching of the state, and improve the intelligent operation.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and more specifically, relates to a control method, device and system. Background technique [0002] With the rapid development of the Internet, TV is no longer just a tool for watching TV programs. The dedicated computer that interacts with the TV through the interface makes the TV have more functional attributes of human-computer interaction. [0003] For example, a special computer Stick PC, the Stick PC can be connected with a TV through a USB (Universal Serial Bus, Universal Serial Bus) interface, so that the Stick PC can be powered by the TV and the multimedia data in the Stick PC can be transmitted to the TV. TV to display on the TV. [0004] In this context, when the Stick PC is connected to the TV and the current TV is playing the video transmitted by the set-top box, if you want to switch to playing the video transmitted by the Stick PC, you must first turn on the Stick PC, a...
