Set-top box standby method, set-top box standby control device, and set-top box

Abstract

Embodiments of the present invention provide a set-top box standby method, a set-top box standby control device, and a set-top box. The method includes: receiving a standby signal of a top box; controlling at least one unused functional module in the set-top box to enter a low power consumption state, so that the set-top box enters an active standby state; All functional modules except the remote control interface module and the power control module are powered off, so that the set-top box enters a deep standby state; otherwise, the system-on-a-chip SOC that controls the set-top box enters dormant mode and controls random access memory RAM to retain the described SOC to enter parameters before the sleep mode, and control at least one functional module in the set-top box except the SOC and the RAM to be powered off, so that the set-top box enters a fast standby state. The embodiments of the present invention take into account the realization of low power consumption of the set-top box and the shortening of the time from standby to start-up of the set-top box.

Description

technical field [0001] The invention relates to information technology, in particular to a set-top box standby method, a set-top box standby control device and a set-top box. Background technique [0002] At present, more and more attention is paid to the rationality of energy consumption of the set-top box, and it is usually required that the power consumption of the set-top box in a standby mode be within a certain range. [0003] In the prior art, a switch is provided on the operating system power supply circuit of the set-top box, and the switch is controlled by a single-chip microcomputer that is always in a working state. When receiving the operating system standby signal, the single-chip microcomputer control switch cuts off the power supply of the operating system to make the system standby. However, since the current operating system design of set-top boxes generally uses a single chip to integrate the functions of the entire system, more and more tasks and program...

Problems solved by technology

However, since the current operating system design of set-top boxes generally uses a single chip to integrate the functions of the entire system, more and more tasks and programs are run on a single chip, resulting in a longer time for the set-top box to start from standby.
