Energy saving method of digital television receiving terminal and digital television receiving terminal

Abstract

The invention discloses an energy saving method of a digital television receiving terminal and the digital television receiving terminal. The method comprises that a use habit of a user to the digital television receiving terminal is counted and a counting result is generated; and an operating mode of the digital television receiving terminal is adjusted according to the counting result and starting configuration satisfying using demands for the digital television receiving terminal of the user is generated. Modules which are not used usually are capable of automatically entering to a state of sleep or module power off so that operation dominant frequency of a central processing unit (CPU) is automatically reduced to an appropriate value under the condition of excess of system resources and the purpose of reducing complete machine power consumption of the digital television receiving terminal is achieved.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to an energy-saving method for a digital television receiving terminal and the digital television receiving terminal. Background technique [0002] With the gradual popularization of high-definition digital receiving TV receiving terminals (HD set-top boxes), especially two-way digital TV receiving terminals, applications and functional interfaces based on digital TV receiving terminals are becoming more and more abundant, and the increase in functions has led to digital TV receiving terminals. The power consumption is also gradually increasing, and there is a tendency to move closer to the PC. For digital TV receiving terminals, the small system composed of CPU, flash memory, and double-rate synchronous dynamic random access memory (DDR SDRAM) undoubtedly accounts for the vast majority of the power consumption of the whole machine. However, in actual use, due to the , p...

Problems solved by technology

For digital TV receiving terminals, the small system composed of CPU, flash memory, and double-rate synchronous dynamic random access memory (DDR SDRAM) undoubtedly accounts for the vast majority of the power consumption of the whole machine. However, in actual use, due to the , program source, network and other restrictions, most ordinary users often use some very simple functional modules, while network interface, HDMI interface, cable modem (Cable Modem) module, etc. are rarely used, even high-definition program Therefore, if the system of the digital TV receiving terminal blindly works according to the default configuration, it will undoubtedly lead to a large waste of energy

[0003] The existing true standby technology can only ensure that the receiver can reduce power consumption in the standby state, but cannot guarantee that it can also reduce power consumption in the normal working state; while the active module shutdown or frequency reduction technology lacks sufficient flexibility, and Lack of consideration and differentiation of user habits
