Problems solved by technology
The existing technology also provides a solution based on the HDMI interface to realize the state synchronization between the TV and the TV, but it does not provide a solution for how to achieve low power control in combination with low power consumption technology, and only causes the set-top box and smart TV The state synchronization among them, rather than from the combination of low power consumption circuit itself to achieve more effective energy-saving control

Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0040] In the specific implementation process, when it is judged that the TV control command is a standby signal, the standby signal is sent to the control board of the smart TV based on the HDMI interface; the control board of the smart TV detects the working state of the low-power circuit on the smart TV based on the standby signal, and Put the low-power circuit in the standby mode; when it is judged that all the low-power circuits are in the standby mode, configu...

The invention discloses a method and system for controlling an intelligent television with low power consumption. The method comprises steps: a standby signal is transmitted to a control mainboard of an intelligent television based on an HDMI interface when a television control order is determined as the standby signal; an intelligent television low power circuit is put under a standby mode; when a fact that all low power circuits are put in a standby mode is determined, a low level is configured on a TMDS signal port of the HDMI interface; when the TMDS signal port is in a low level, a set top box enters a low power consumption standby state or a dormancy state, the power supply controller is switched from the main power supply to an auxiliary power supply to realize low power consumption power supply. The method and the system for realizing low power consumption intelligent television control realize low power consumption control based on the HDMI interface, finishe low power consumption control under a standby mode or a starting up mode, and thus realize energy saving control.
Description
technical field [0001] The invention belongs to the technical field of digital television, and in particular relates to a method for realizing low power consumption control of an intelligent television and the intelligent television. Background technique [0002] Smart TV is a new TV product with a fully open platform and equipped with an operating system. Users can install and uninstall various application software by themselves while enjoying ordinary TV content, and continuously expand and upgrade functions. Smart TVs can continue to bring users rich and personalized experiences that are different from those using cable digital TV receivers (set-top boxes). [0003] With the rapid development of computer technology and microelectronics technology, the application fields of embedded systems are becoming more and more extensive. Energy saving is a global craze. For example, many chips in computers used to be powered by 5V, but now they use 3.3V and 1.8V, and the concept of...
