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

Abstract

The embodiment of the invention provides a set-top box standby method, a set-top box standby control apparatus and a set-top box. The standby method comprises the following steps that: a standby signal of a set-top box is received; at least one function module that is not used in the set-top box is controlled to enter a low-power consumption state, so that the set-top box enters an active standby state; if a set condition is satisfied, all function modules except a remote control interface module and a power supply control module of the set-top box are controlled to realize outage, so that the set-top box enters a deep standby state; otherwise, a system-level chip SOC of the set-top box is controlled to enter a sleep mode and a random access memory (RAM) is controlled to retain a parameter of the SOC before the entrance to the sleep mode; and at least one function module except the SOC and the RAM of the set-top box is powered off, so that the set-top box enters a rapid standby state. According to the embodiment of the invention, the low power consumption of the set-top box is realized and the time from the standby to starting of the set-top box can be shortened.

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...

AI Technical Summary

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.
