detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Fig. 1 is the flowchart of an embodiment of the set-top box standby method provided by the present invention, as shown in Fig. 1, the method comprises:

S101. Receive a standby signal of a top box.

S102. Control 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.

S103, if the setting conditions are met, then control the power-off of all functional modules in the set-top box except the remote control interface module and the power control module, so that the set-top box enters a deep standby state; otherwise, control the SOC of the set-top box to enter a sleep mode and control RAM retention Parameters before the SOC enters the dormancy mode, and controls power-off of at least one functional module in the set-top box except the SOC and RAM, so that the set-top box enters a fast standby state.

The execution subject of the above steps may be various types of single-chip microcomputers, micro control units (Micro Control Unit, MCU) or control circuits installed in the set-top box.

When the set-top box needs to enter the standby state, the set-top box will send a standby signal through the operating system. The set-top box standby method provided by the present invention can firstly control at least one unused functional module in the set-top box to enter a low power consumption state after receiving the standby signal sent by the set-top box, so that the set-top box enters an active standby state. Wherein, controlling at least one unused functional module in the set-top box to enter a low power consumption state may include: controlling some unused functional modules in the set-top box to be turned off, for example: an audio module or a video module can be turned off, so that the set-top box has no output; it can be turned off For unused functional modules such as the decoding module, the user can experience that the set-top box enters the standby state. It may also be to control the power-off operation of some unused functional modules in the set-top box, or to realize the operation of making the unused functional modules enter a low power consumption state through software control.

Since at least one functional module in the set-top box enters a low power consumption state, the energy consumption of this part of the functional modules is saved. It is understandable that the system-on-chip (System On Chip, SOC) of the set-top box (equivalent to the CPU of the set-top box) is not powered off. Therefore, when the set-top box enters the active standby mode, if you need to start the set-top The functional modules in the power consumption state enter the normal working state, and the time for the set-top box to enter the normal working state from active standby to control the functional modules entering the low power consumption state is relatively short.

On the basis of the set-top box entering the active standby mode, if the set condition is satisfied, the set-top box can also be controlled to enter the fast standby state or the deep standby state.

The fast standby state can be: the system function of the set-top box operating system is stopped, the SOC of the set-top box enters the dormant state, and the random access memory (Random Access Memory, RAM) of the set-top box retains various parameters at the last moment before the set-top box enters the dormant state. Specifically, it can be to save the set-top box The operating status of the operating system, the setting status of various registers, etc. Other functional modules in the set-top box are powered off. Optionally, functional devices with low power consumption such as infrared, timer, and indicator light can be reserved. Since the SOC in the fast standby state is in a dormant state and the RAM retains various parameters at the last moment before the set-top box enters the dormant state, the set-top box can be quickly woken up from the fast standby state, usually within 5 seconds from the fast standby state.

The deep standby state may be: all functional modules in the set-top box except the remote control interface module and the power control module are powered off, and the SOC and RAM are also in the power-off state. In this standby mode, the set-top box can receive remote control signals. The time required for the set-top box to start up from the deep standby state is longer than that of the active standby state and the fast standby state.

Certain conditions can be preset by the user. The user can set the state bit of the going out mode (Holiday mode). When the user goes out and does not need to use the set-top box for a period of time, the user can set the "Holiday mode" to "true" (true) , otherwise you can set "Holiday mode" to "false". After the STB enters the active standby state, if the "Holiday mode" is set to "true", the STB can be controlled to enter the deep standby state from the active standby state.

The user can also set the one-button energy-saving mode (Eco mode) status bit, the user can set the "Eco mode" to "true" or "false", after the standby STB enters the active standby state, if the "Eco mode" is set to "true" , then the set-top box can be controlled to enter the deep standby state from the active standby state.

The user can also set the effective time window (time window) indicating that the set-top box is in working hours, wherein the effective time window can be set according to the user's needs, for example: the user can set the effective time window to the working time period of the day from 8:00 to 17 :00. After the STB enters the active standby state, within the effective time window (in time window), the STB can be controlled to enter the deep standby state from the active standby state.

Specifically, all functional modules in the set-top box except the remote control interface module and the power control module can be controlled to be powered off, and the SOC and RAM are also in a power-off state, so that the set-top box enters a deep standby state.

If the set-top box does not meet the set conditions after entering the active standby state, for example: "Holiday mode" is set to "false", and "Eco mode" is set to "false", and it is not within the range of the effective time window (out of timewindow ), then the set-top box can be controlled to enter the fast standby state from the active standby state.

Specifically, it is possible to control the SOC of the set-top box to enter the dormant state, and control a random access memory (Random Access Memory, RAM) to retain various parameters at the last moment before the set-top box enters the dormant state. The other at least one functional module in the set-top box can be controlled to be powered off. For example: infrared, timer, indicator light and other functional devices with low power consumption, while controlling other unused functional modules to be powered off.

Optionally, after the set-top box enters the active standby state, it can also be judged whether each functional module in the set-top box is in use, and if each functional module in the set-top box is not in use, then the set-top box can be further controlled to enter a deep standby state or a fast standby state; If there are still functional modules in use in the set-top box, the set-top box may be kept in an active standby state.

The set-top box standby method provided by the embodiment of the present invention controls the unused functional modules in the set-top box to enter a low power consumption state after the set-top box sends a standby signal, so that the set-top box enters the active standby mode; after the set-top box enters the active standby mode, if condition, then close all functional modules in the set-top box except the remote control interface module and the power control module, so that the set-top box enters the deep standby mode; parameter, turn off and control the power-off of unused functional modules in the set-top box, so that the set-top box enters the fast standby mode. Realize setting the hierarchical standby mode according to different states of the set-top box, realize low power consumption of the set-top box and shorten the time from standby to start-up of the set-top box.
