The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a flow chart of an embodiment of a set-top box standby method according to the present invention. As shown in FIG. Includes:

5101, standby signal of the receiver top box.

5102. Control at least one function module that is not used in the set top box to enter a low power state, so that the set top box enters an active standby state.

S103. If the setting condition is met, all the functional modules except the remote control interface module and the power control module in the set top box are powered off, so that the set top box enters a deep standby state; otherwise, the S0C of the control set top box enters the sleep mode and the control RAM remains. The S0C enters the parameters before the sleep mode, and controls at least one function module except the S0C and the RAM in the set top box to be powered off, so that the set top box enters the fast standby state.

The main body of the above steps may be various types of single-chip microcomputers, Micro Control Units (MCUs) 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, after receiving the standby signal sent by the set-top box, can first control at least one function module not used in the set-top box to enter a low-power state, thereby causing the set-top box to enter an active standby state. The controlling the at least one function module in the set top box to enter the low power consumption state may include: controlling some unused function modules in the set top box to be closed, for example: the audio module or the video module may be turned off, so that the set top box has no output; The function module that is not used by the decoding module or the like, the user can experience that the set top box enters the standby state. It can also control the power-off operation of some unused function modules in the set-top box, or it can be implemented by software control to make the unused function modules enter the low-power state.

Since at least one of the functional modules in the set top box enters a low power state, the power consumption of the functional modules is saved. It can be understood that the system-on-chip (S0C) 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 the set-top box needs to be started, only the control needs to be low. The function module of the power consumption state enters the normal working state, and the time when the set-top box enters the normal working state from the active standby to the control module that enters the low-power state is small.

On the basis that the set top box enters 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 S0C of the set-top box enters a sleep state, and the random access memory (RAM) of the set-top box retains various parameters at the last moment before the set-top box enters the sleep state, specifically, the set-top box can be saved. The operating state of the operating system, the setting status of various registers, and so on. The other functional modules in the set-top box are powered off. Optionally, functional devices with low power consumption such as red, timer, and indicator lights can be reserved. Since the S0C in the fast standby state is in the sleep state and the RAM retains various parameters at the last moment before the set top box enters the sleep state, the set top box can be quickly awakened from the fast standby state. Usually the time to start from the fast standby state is within 5 seconds.

The deep standby state can be: All the function modules except the remote control interface module and the power control module in the set-top box are powered off, and the S0C and RAM are also powered off. In this standby mode, the set-top box can receive the remote control signal. The time required for the set-top box to go from deep standby to startup is longer than active standby and fast standby.

The user can set certain conditions in advance, and the user can set the "Loliday mode" status bit. When the user goes out and does not need to use the set top box for a certain period of time, the user can set "Holidaymode" to "true" (true), otherwise You can set "Holiday mode" to "false" (false). After the standby top box enters the active standby state, if "Holidaymode" is set to "true", the set-top box can be controlled to enter the deep standby state from the active standby state.

The user can also set the Eco mode status bit. The user can set the "Eco mode" to "true" or "false". After the standby top box enters the active standby state, if "Eco mode" is set to "true". , you can control the set-top box to enter the deep standby state from the active standby state.

The user can also set a time window indicating that the set-top box is in working time, wherein the effective time window can be set according to user requirements, for example: The user can set the effective time window to the time period of daytime work: 8: 0 (Γ17 :00. After the standby top box enters the active standby state, within the effective time window (in time window), the set top box can be controlled to enter the deep standby state from the active standby state.

Specifically, all the functional modules except the remote control interface module and the power control module in the set top box can be powered off, and the S0C and RAM are also powered off, so that the set top box enters a deep standby state.

If the setting condition is not met after the set-top box enters the active standby state, for example: "Holidaymode" is set to "false" and "Eco mode" is set to "false" and is not within the valid time window (out of time window ), you can control the set-top box to enter the fast standby state from the active standby state.

Specifically, the S0C of the set top box can be controlled to enter a sleep state, and the random access memory (RAM) is controlled to retain various parameters of the last moment before the set top box enters the sleep state. It is possible to control the power failure of at least one of the other functional modules in the set top box. For example: Infrared, timers, indicators, and other low-power functional devices, while controlling other unused functional modules to power down.

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

The set-top box standby method provided by the embodiment of the present invention controls the unused function module of the set-top box to enter a low-power state after the set-top box issues a standby signal, so that the set-top box enters the active standby mode; After the mode, if the set condition is met, all the functional modules except the remote control interface module and the power control module in the set top box are turned off, so that the set top box enters the deep standby mode; otherwise, the S0C in the set top box enters the sleep mode and controls the random access RAM. Keep the parameters before the S0C enters the sleep mode, and turn off the unused function modules in the control set-top box to power off, so that the set-top box enters the fast standby mode. A hierarchical standby mode is set according to different states of the set top box, which realizes low power consumption of the set top box and shortens the time from the standby to the start of the set top box.
