Description

Technical Field

[0001] This invention belongs to the field of TV box power consumption control technology, specifically relating to a deep standby power consumption control system, method, and smart TV box. Background Technology

[0002] A smart TV box is an embedded terminal device that connects to a traditional television set. It uses interfaces such as HDMI to treat the television as a display output device and utilizes its built-in hardware system (including a main control chip, memory, storage, and network modules) and smart operating system to build a complete computing platform. The core function of this device is to access the internet via a network, thereby obtaining and decoding massive amounts of audio and video content provided by streaming media service providers. This changes the traditional one-way broadcasting viewing model of television, allowing users to watch content on demand.

[0003] Currently, the standby state of smart TV boxes is actually still a light standby mode. Although the main chip's operating frequency can be reduced to several hundred megahertz and some clock signals are partially shut down, the core voltage and some external power supply lines continue to operate. This results in long-term current leakage in components such as the network interface physical layer, USB bus power, HDMI control signal pull-up circuits, and panel indicator lights, leading to relatively high actual standby power consumption. Existing technologies employ power isolation technology within the main chip, using on-chip memory to retain a small amount of operating state before cutting off the core voltage supply. However, such solutions still cannot eliminate static power consumption at the input / output interfaces and are highly dependent on specific chip architectures, resulting in poor system portability and adaptability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of high standby power consumption and inflexible implementation methods of existing smart TV boxes, thereby providing a deep standby power consumption control system, method and smart TV box.

[0005] A deep standby power consumption control method includes the following steps: The MCU controls the power management module, enabling the smart TV box system to operate in either standby or operating mode. In standby mode, the power management module maintains power supply to the MCU power domain and memory power domain, while disconnecting power supply to the main control power domain, flash memory power domain, Ethernet power domain, USB power domain, SPDIF power domain, and HDMI power domain. In operating mode, the power management module maintains power supply to the MCU power domain and memory power domain, while turning on power supply to the main control power domain, flash memory power domain, Ethernet power domain, USB power domain, SPDIF power domain, and HDMI power domain. In standby mode, the monitoring module listens for the wake-up signal. Upon detecting the wake-up signal, the MCU controls the main control module to power on and verify the wake-up signal. After successful verification, the MCU controls the power management module to put the smart TV box into working mode.

[0006] Furthermore, when transitioning from the working state to the standby state: the smart TV box operating system running in the main control module initiates standby, the flash memory module enters sleep mode, the memory module enters self-refresh mode, writes the recovery information into the MCU's built-in storage, and the main control module sends a standby signal; after receiving the standby signal, the MCU controls the power management module to disconnect the power supply to the main control power domain, disconnect the power supply to the flash memory power domain, and disconnect the power supply to the Ethernet power domain, USB power domain, SPDIF power domain, and HDMI power domain.

[0007] Furthermore, after entering standby mode, the MCU switches to low-frequency oscillator for monitoring.

[0008] Furthermore, after the IR monitoring unit in the monitoring module receives the infrared remote control signal, the MCU decodes the infrared remote control signal through the built-in decoder. When the infrared remote control signal includes a preset specific brand code and a valid key value, the MCU controls the power management module to put the smart TV box into working state.

[0009] Furthermore, the Bluetooth monitoring unit in the monitoring module maintains a preset broadcast monitoring period. After discovering a device with a preset MAC address, it sends a Bluetooth wake-up signal to the MCU. After receiving the Bluetooth wake-up signal, the MCU controls the power management module to power on the Bluetooth module and the main control power domain. It compares the whitelisted MAC addresses through the Bluetooth protocol stack. If the MAC addresses match, it controls the power management module to put the smart TV box into working state.

[0010] Furthermore, the Wi-Fi WOW monitoring unit in the monitoring module filters data packets using DTIM and GTK. After successfully matching a data packet, it sends a Wi-Fi wake-up signal to the MCU. Upon receiving the Wi-Fi wake-up signal, the MCU controls the power management module to power on the main control power domain. The main control module checks the information in the data packet. If it matches a preset rule, the MCU controls the power management module to put the smart TV box into working mode.

[0011] Furthermore, the network port WoL monitoring unit in the monitoring module matches the preset data packet MAC address and identification code through PHY hardware. After successful matching, it sends a network port WoL wake-up signal to the MCU. After receiving the network port WoL wake-up signal, the MCU controls the power management module to power on the main control power domain. The main control module verifies the data packet through SHA-HMAC. If the verification passes, the MCU controls the power management module to put the smart TV box into working state.

[0012] Furthermore, the HDMI-CEC monitoring unit in the monitoring module sends an HDMI-CEC wake-up signal to the MCU through CEC PHY pre-screening of preset type operation codes; after receiving the HDMI-CEC wake-up signal, the MCU controls the power management module to power on the main control power domain, the main control module reads the CEC FIFO, checks the source address and logical address, and if they pass, the MCU controls the power management module to put the smart TV box into working state.

[0013] A deep standby power consumption control system for controlling a smart TV box using the aforementioned power consumption control method, comprising an MCU, a main control module, a power management module, and a monitoring module; The MCU controls the power management module, which divides the smart TV box system into multiple power domains to provide operating power for the hardware of the smart TV box and drive the power domains to power on and off. The power domain includes a constant power domain and multiple power-off domains; the constant power domain includes an MCU power domain and a memory power domain; the power-off domain includes a main control power domain, a flash memory power domain, an Ethernet power domain, a USB power domain, an SPDIF power domain, and an HDMI power domain. The monitoring module operates in the MCU power domain and is connected to the MCU signal to monitor the wake-up signal.

[0014] A smart TV box, characterized in that power consumption control is achieved through the aforementioned deep standby power consumption control method. Beneficial Effects: This invention discloses a deep standby power consumption control system, method, and smart TV box. An MCU controls a power management module, which divides the smart TV box system into multiple power domains and controls the power-on and power-off of these domains. In standby mode, the power management module maintains power supply to the constant power domains and disconnects power to the power-off domains. Simultaneously, a monitoring module listens for wake-up signals. Upon detecting a wake-up signal, the MCU partially powers on the main control module to verify the wake-up signal. After successful verification, the power management module enables the smart TV box to enter the working state. This invention achieves flexible hardware power-off of the power-off domains through MCU control of the power management module in standby mode, enabling wake-up as needed while avoiding leakage, significantly reducing standby power consumption. Furthermore, the partial power-on verification upon detecting a wake-up signal reduces erroneous wake-up exits from standby, further lowering standby power consumption. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] Example 1: Reference Figure 1 As shown, this embodiment provides a deep standby power consumption control method, including the following method steps: The MCU controls the power management module, enabling the smart TV box system to operate in either standby or operating mode. In standby mode, the power management module maintains power supply to the MCU power domain and memory power domain, while disconnecting power supply to the main control power domain, flash memory power domain, Ethernet power domain, USB power domain, SPDIF power domain, and HDMI power domain. In operating mode, the power management module maintains power supply to the MCU power domain and memory power domain, while turning on power supply to the main control power domain, flash memory power domain, Ethernet power domain, USB power domain, SPDIF power domain, and HDMI power domain. In standby mode, the monitoring module listens for the wake-up signal. Upon detecting the wake-up signal, the MCU controls the main control module to power on and verify the wake-up signal. After successful verification, the MCU controls the power management module to put the smart TV box into working mode.

[0021] Specifically, when transitioning from working state to standby state: the smart TV box operating system running in the main control module initiates standby, the eMMC receives CMD5 commands, the flash memory module enters sleep mode, the DDR memory module enters self-refresh mode, and writes the Resume Header information into the MCU's built-in storage AO-SRAM. The main control module pulls the "Deep-Ack" signal high to issue a standby signal, indicating that the software is ready to power off. After receiving the standby signal, the MCU controls the power management module to set SYS_EN1 low to disconnect the power supply to the main control power domain, set SYS_EN2 low to disconnect the power supply to the flash memory power domain, and pull all SYS_EN3~SYS_EN6 low to disconnect the power supply to the PERI domains such as the Ethernet power domain, USB power domain, SPDIF power domain, and HDMI power domain.

[0022] In this embodiment, after entering standby mode, the MCU switches to the 32kHz low-frequency oscillator for monitoring.

[0023] Specifically, different verification and power-on procedures are set for different wake-up sources of the monitoring module in standby mode.

[0024] When the IR monitoring unit in the monitoring module receives an infrared remote control signal, the MCU decodes the signal using its built-in decoder. If the signal includes a preset brand code and a valid key value, the MCU controls the power management module to put the smart TV box into operation. Upon entering power-on mode, the MCU sequentially pulls high HDMI_EN, MAIN_EN, and the LED, powering on the HDMI module, main control module, and LED in sequence. The USB / Ethernet port power-on is delayed, determined by the system power management. In infrared wake-up mode, user-visible responses take priority, followed by the HDMI / display path, with the eMMC powered on first to ensure the UI resources are mounted.

[0025] Specifically, during infrared wake-up, the strategy is to first display the image and then activate the network. The power-on process is as follows: SYS_EN1MAIN boosts DVFS; the DDR module exits self-refresh mode; SYS_EN2 eMMC power-on initializes to ensure UI resources are available; SYS_EN6 HDMI DDC / CEC power supply restores DDC pull-up and transceiver, waiting for HPD and EDID to be ready; the minimum video PLL / clock is turned on to illuminate the UI; the network (ETH / Wi-Fi) is delayed and powered up by the system power management according to the strategy; when needed, SYS_EN3 (ETH) or the Wi-Fi main power is then activated.

[0026] When the Bluetooth monitoring unit in the monitoring module maintains a preset broadcast monitoring period and discovers a device with a preset MAC address, it sends a Bluetooth wake-up signal to the MCU. Upon receiving the Bluetooth wake-up signal, the MCU controls the power management module to power on the Bluetooth module and the main power domain. It then compares the MAC addresses in the whitelist using the Bluetooth protocol stack. If the MAC addresses match, the MCU controls the power management module to put the smart TV box into working mode. At this time, upon entering the power supply state, the MCU sequentially powers on the eMMC and LEDs, and the application layer implements the receiving button or pairing process. In the case of Bluetooth wake-up, the optimization goal is to ensure that the remote control is always available.

[0027] Specifically, during Bluetooth remote wake-up, the strategy is to first activate the wireless block, and then activate the network as needed. The power-on process is as follows: SYS_EN1 MAIN DDR module recovery; SYS_EN2 eMMC initialization; enabling the main power of the Wi-Fi / BT module (if it is an SDIO module, a separate "WL_MAIN" switch; if it is a USB Wi-Fi / BT, it shares the 5V VBUS of SYS_EN4) only powers on the Bluetooth subsystem; restore the Bluetooth protocol stack and complete the HID / pairing session; light up the UI; Wi-Fi / ETH is delayed according to the strategy.

[0028] When the Wi-Fi WOW monitoring unit in the monitoring module filters data packets using DTIM and GTK, it sends a Wi-Fi wake-up signal to the MCU after successfully matching a data packet. Upon receiving the Wi-Fi wake-up signal, the MCU controls the power management module to power on the main control power domain. The main control module checks the information in the data packet; if it matches a preset rule, the MCU controls the power management module to put the smart TV box into working mode. At this time, upon entering the power supply state, the MCU sequentially powers on the 3.3V high-power segment of the Wi-Fi module, the USB port, and the LED. During Wi-Fi WOW wake-up, wireless connectivity is restored with minimal cost; the wired port does not need to be simultaneously activated, avoiding additional power consumption caused by simultaneous dual-stack wake-up.

[0029] Specifically, when Wi-Fi WOW is activated, the strategy is to first activate the Wi-Fi network, and then activate other modules as needed. The power-on process is as follows: SYS_EN1 MAIN DDR module is restored; SYS_EN2 eMMC module is initialized; the high-power segment of the Wi-Fi main power (PA / LNA / PLL) is pulled up, and the SDIO / PCIe host ports are restored; the kernel restores the WLAN interface, and the upper-layer network session is resumed (DHCP / encryption context is maintained by the chip or quickly rebuilt); the UI is turned on; ETH / USB remains powered off unless required by the business.

[0030] When the Ethernet port WoL monitoring unit in the monitoring module matches the preset data packet MAC address and identification code through PHY hardware, it sends an Ethernet port WoL wake-up signal to the MCU upon successful matching. Upon receiving the WoL wake-up signal, the MCU controls the power management module to power on the main control power domain. The main control module verifies the data packet using SHA-HMAC. If the verification passes, the MCU controls the power management module to put the smart TV box into working mode. At this time, upon entering the power supply state, the MCU sequentially pulls ETH_EN, MAIN_EN, and eMMC_EN high, powering on the Ethernet module, main control module, and flash memory module in sequence, reviving network services within 300ms. When waking up via Ethernet port WoL, considering the typical scenario of remote control / maintenance, network priority is given to ensure immediate availability of SSH / TR-069 / OTA. Powering on the Ethernet module in advance allows for a smoother transition of the adapter from burst mode to continuous mode.

[0031] Specifically, during Wake-on-Ethernet (WEE), the strategy is to first activate the Ethernet module and then display the UI. The power-on process is as follows: SYS_EN3 ETH main power-on; if only PHY_AO is retained in the first segment, then PHY_MAIN_3V3 is pulled up. Wait for PHY clock locking / auto-negotiation; SYS_EN1 MAIN DDR recovery; SYS_EN2 eMMC initialization; restore the Ethernet stack / session first, then turn on the UI; other peripherals (USB / HDMI / SPDIF) are enabled according to the strategy.

[0032] When the HDMI-CEC monitoring unit in the monitoring module sends an HDMI-CEC wake-up signal to the MCU via a pre-filtered operation code of the CEC PHY, the MCU, upon receiving the HDMI-CEC wake-up signal, controls the power management module to power on the main control power domain. The main control module reads the CEC FIFO and checks the source address and logical address. If they pass, the MCU controls the power management module to put the smart TV box into working mode. At this time, upon entering the power supply state, the MCU sequentially powers on the HDMI module, main control module, and LED, with the USB / Ethernet port powering on depending on the system strategy. Wake-up via HDMI-CEC often occurs in TV power-on scenarios. In such cases, a rapid screen brightening should be prioritized without creating noise / light interference, and CEC / DDC should be restored first to avoid handshaking errors due to bus undervoltage.

[0033] Specifically, when HDMI-CEC wakes up, the strategy is to first display the image and then remain silent; the power-on process is as follows: SYS_EN6 restores DDC / CEC power supply (DDC pull-up is effective), confirms HPD; SYS_EN1 MAIN DDR is restored; SYS_EN2 eMMC is initialized; minimum video clock / PLL is enabled, UI is lit, and normal handshake of CEC / EDID / HDCP is completed with the TV side; the network domain is delayed according to the strategy, maintaining the silent back-on of the living room scene.

[0034] Example 2: This embodiment provides a deep standby power consumption control system for controlling a smart TV box using the power consumption control method described in Embodiment 1, including an MCU, a main control module, a power management module, and a monitoring module; The MCU controls the power management module, which divides the smart TV box system into multiple power domains to provide operating power for the hardware of the smart TV box and drive the power domains to power on and off. The power domain includes a constant power domain and multiple power-off domains; the constant power domain includes an MCU power domain and a memory power domain; the power-off domain includes a main control power domain, a flash memory power domain, an Ethernet power domain, a USB power domain, an SPDIF power domain, and an HDMI power domain. The monitoring module operates in the MCU power domain and is connected to the MCU signal to monitor the wake-up signal.

[0035] The specific model of the power management module is DA9063, which can achieve six-channel power supply control through six SYS_EN channels. The MCU is a threshold voltage MCU, which provides power at 8µA in DeepSleep mode. It drives the SYS_EN1–6 of the DA9063 through I²C + 6 GPIOs to achieve eight-channel power hard-shutdown / power-on.

[0036] Specifically, the MCU power domain (AO-LP) is a 1.1V / 3.3V DC power supply. The 1.1V DC power supply is provided by the LD01 or Buck (LD0) of the power management module, which powers the MCU, its RTC and 4KB of built-in memory (AO-SRAM); the 3.3V DC power supply is current-limited to 50–150mA and powers the monitoring module.

[0037] The memory power domain (DDR-RET) is powered by a DC power supply of 0.35–0.6V, which is powered by the LD02 of the power management module. It is connected to the VDD2 / reserved pin of the LPDDR4X memory module to retain data for the LPDDR4X memory module's self-refresh.

[0038] In this embodiment, the monitoring module includes an IR monitoring unit, a Wi-Fi WOW monitoring unit, a network port WOL monitoring unit, and an HDMI-CEC monitoring unit.

[0039] As a further improvement to this embodiment, a power adapter is also included. In standby mode, the MCU controls the single-wire PSM_CTRL to pull the AC-DC adapter into a low-load, high-efficiency / burst / eco mode, reducing power consumption from 150mW to 10mW. When the smart TV box system wakes up from standby mode, the power adapter automatically exits burst mode and resumes continuous switching, allowing the entire device to power on normally.

[0040] Example 3: This embodiment provides a smart TV box, which has a built-in deep standby power consumption control system as described in Embodiment 2, and achieves power consumption control through the deep standby power consumption control described in Embodiment 1.

[0041] This embodiment discloses a deep standby power consumption control system, method, and smart TV box. An MCU controls a power management module, which divides the smart TV box system into multiple power domains and controls the power-on and power-off of these domains. In standby mode, the power management module maintains power supply to the constant power domains and disconnects power to the power-off domains. Simultaneously, a monitoring module listens for wake-up signals. Upon detecting a wake-up signal, the MCU partially powers on the main control module to verify the wake-up signal. After successful verification, the power management module enables the smart TV box to enter the working state. This invention achieves flexible hardware power-off of the power-off domains through MCU control of the power management module in standby mode. It can wake up as needed while avoiding leakage, significantly reducing standby power consumption. Furthermore, the partial power-on verification upon detecting a wake-up signal reduces erroneous wake-up exits from standby, further reducing standby power consumption.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
