Abstract: A mini LED television control system and method to reduce loss includes a power supply used for supplying power to a backlight board after a voltage is adjusted; a control board connected to the power supply, the control board including an FPGA used for detecting a current value and controlling a power supply output voltage, an analog-to-digital conversion chip used for collecting the voltages of sampling circuits, and a plurality of sampling circuits connected to a plurality of light boards and used for collecting voltages of the light boards; constant current ICs disposed on the light boards and used for providing light bar voltages and sending brightness information; and a mainboard connected to the control board and used for enabling and synchronizing backlight brightness signals. The control board converts brightness information sent by the mainboard and then sends the information to the constant current ICs on corresponding light boards.

Abstract: Disclosed are a television time shifting control method, a television time shifting control system and a computer-readable storage medium. The television time shifting control method, applied to the television time shifting control system, includes the steps as follows: acquiring a captured picture of a preset area via the camera module, and sending the picture to the recognition module by the television; acquiring picture information of the picture using a preset algorithm by the recognition module; sending a control instruction to the time shifting control module based on the picture information by the recognition module; and performing time shifting control according to the control instruction by the time shifting control module. The present disclosure simplifies the time shifting function, and improves user's viewing experience.

The method includes: a television obtaining a link address of a multimedia resource and determining whether having an online player capable of playing the multimedia resource; the television establishing a connection with a server based on a determination that the television does not have the online player capable of playing the multimedia resource; and the television sending the link of the multimedia resource to the server, such that the server transcodes the multimedia resource according to the link of the multimedia resource.

Abstract: Disclosed are a smart television playing method and a smart television playing device, applied to a smart television of the WebKit-based WebOS, the smart television playing method including: when the smart television is turned on, starting a WebKit kernel process based on a Linux kernel and a driver layer; starting a state management daemon to detect a control command received by the smart television; and sending the control command to a daemon corresponding to the control command via the WebKit kernel process, allowing the daemon to perform control operation corresponding to the control command.

Abstract: Provided are a method for reducing the power consumption of a power supply, a power supply capable of automatically reducing power consumption, and a television. The power supply includes: a voltage sampling circuit, an optocoupler feedback circuit, a deep standby control circuit, a power supply management circuit and an output rectifier filter. The output rectifier filter includes an output capacitor. The feedback amount (a second level or a first level) of the optocoupler feedback circuit changes as the charge amount of the output capacitor changes, intermittently controlling the power supply management circuit to stop working while achieving a constant voltage output.
