Problems solved by technology

[0004] In the current screen projection solution, when the projection terminal transmits the screen content to the receiving terminal in real time, PowerXtend needs to take effect on a single device, and it is difficult to achieve the power saving effect of two devices (that is, the transmitting sub-device and the receiving terminal).
[0005] For the problem in the related art that the transmitting device and the receiving terminal cannot cooperate to save power during screen projection, no effective solution has been proposed so far.

Abstract

The invention discloses a projection power saving method and device. The method comprises steps that a present application state is determined by present equipment after projection connection is established; power saving strategies and parameters are adjusted by the present equipment according to the application state; the power saving strategies and the parameters are sent by the present equipment through a projection transmission link to opposite-end equipment; the present equipment is a projecting terminal for projection, and the opposite-end equipment is a reception terminal for projection; or the present equipment is a reception terminal for projection, and the opposite-end equipment is a projecting terminal for projection. Through the method, cooperative power saving between the projecting terminal and the reception terminal is realized, on one hand, the optical power saving effect of the projecting terminal and the reception terminal is guaranteed, on the other hand, user operation and watch experiences of the projecting terminal and the reception terminal can be guaranteed to be consistent.

Description

technical field [0001] The present application relates to the field of computers, in particular to a power saving method and device in projection. Background technique [0002] PowerXtend can greatly reduce the power consumption of mobile terminals on the basis of ensuring the normal use of applications in mobile terminals. The core technology of PowerXtend lies in the scheme of reducing the total power consumed by computing resources in the image processing process of mobile terminals.
