Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] figure 1 is a flow chart of a set-top box power management method in an embodiment, such as figure 1 As shown, the set-top box power management method includes the following steps:
[0028] S10: Set two standby modes, false standby mode and true standby mode, among which, the false standby mode is to turn off only the audio and video modules, and the rest of the modules work normally; the true standby mode is to turn off the main chip and all peripheral devices, only the microcontroller Work.
[0029] With the intelligent development of set-top boxes and the increase of functions, a singl...

The invention relates to a set top box power supply management method and system. According to the method, two standby modes which are respectively a false standby mode and a real standby mode are arranged, wherein the false standby mode is that only audio and video modules are closed and other modules work normally, and the real standby mode is that a master chip and all peripheral devices are closed and only one single-chip microcomputer works; the frequency when a set top box is at a normal working state in each time period is counted in a preset period, and a time period when the frequency exceeds a set value is obtained; and in the time period when the frequency exceeds the set value, if the set top box is currently not at a normal working state, the set top box is enabled to enter the false standby mode, and in other time periods, when the set top box is currently not at the normal working state, the set top box is enabled to enter the real standby mode. According to the invention, energy consumption of the set top box is effectively reduced, the requirements of users for convenience and easy use are greatly satisfied, application by the users is greatly facilitated, and good experiment is brought to the users.
Description
technical field [0001] The invention relates to digital television equipment, in particular to a set-top box power management method and system. Background technique [0002] With the gradual improvement of awareness of energy saving and emission reduction in modern society, the power consumption of various electronic devices has also received more and more attention and restrictions. Energy consumption standards have been formulated for various electronic devices. Set-top boxes are common and frequently used in families Electronic equipment also needs to minimize energy consumption. [0003] When the set-top box is working normally, the main CPU and various peripheral devices need to work normally, and there is little room for reducing energy consumption. However, in the entire life cycle of the set-top box, most of the time is in the standby mode, and most of the peripheral devices of the machine do not need to work all the time in the standby mode, so it is particularly ...
