Method, device and system for reducing power consumption of Type-C interfaces

Abstract

The invention relates to a method, device and system for reducing power consumption of Type-C interfaces. The method comprises the following steps of: judging whether video/audio playing equipment of a Type-C interface is in an unused state or not; if the video/audio playing equipment of the Type-C interface is in the unused state, closing or reducing an output power supply of an interface; and if the video/audio playing equipment of the Type-C interface is in a used state, keeping the original power supply state of the interface. According to the method, a sensor and/or power supply power consumption setting are utilized to judge whether the video/audio playing equipment is in the unused state or not, and according to the judging result, the problem that the video/audio playing equipment continuously consumes power in the used state or continuously consumes the electric energy of batteries of a mobile phone and a mobile terminal or the video/audio playing equipment in the unused state is solved, so that the using time of the batteries of the mobile phone and the mobile terminal is effectively prolonged, the service life of the batteries of the mobile phone and the mobile terminal is prolonged, the unnecessary electric energy waste is decreased and the power consumption is reduced.

Description

technical field [0001] The present invention relates to the technical field of Type-C interface, and more specifically refers to a method, device and system for reducing power consumption of Type-C interface. Background technique [0002] With the use of digital video and audio interfaces, USB and Type-C interfaces of smartphones, it has more communication control capabilities, richer video and audio interfaces, and more convenient power management capabilities. The original 3.5mm Type-C The interface will also be gradually replaced by the above-mentioned corresponding USB and Type-C interfaces, so the video and audio playback equipment for this type of digital video and audio interface will gradually replace the original 3.5mm stereo, analog Type-C interface traditional video Audio playback equipment, the video and audio playback equipment with Type-C interface has a digital audio processing chip inside, and has a corresponding software program, which is a comprehensive sma...

AI Technical Summary

Problems solved by technology

[0003] Video and audio playback devices with digital video and audio interfaces consume more power than traditional video and audio playback devices. When using digital video and audio USB, Type-C interfaces, and existing USB, Type-C interface video and audio playback devices At present, the system is not perfect in terms of power consumption processing. As long as the digital audio interface video and audio playback device is connected to the device interface, the device will always consume power regardless of whether it is calling or playing audio data. There are strict requirements on power consumption. Therefore, when using digital audio interface video and audio playback equipment, it is easy to waste power

[0004] In addition, relying on the powerful network functions of mobile terminals, as well as rich mo
