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.

Abstract: The disclosure discloses a video signal transmission method, the method includes the following operations: acquiring a target video signal, decoding the target video signal, and dividing the decoded target video signal into a preset number of video signal groups according to a preset strategy; transmitting the video signal groups to a signal processor, and controlling the signal processor to process the video signal groups; transmitting the processed video signal groups to the display terminal to display each group of video signal of the processed video signal groups in a corresponding area of the display terminal. The disclosure also discloses a video signal transmission device.

Abstract: Provided are a data processing method and apparatus for a client. The data processing method for a client includes: acquiring protocol data from a server, where the protocol data is formed from transmission data encapsulated in a set protocol by the server; parsing the protocol data to obtain the set protocol; identifying a protocol header, a protocol body and a protocol exception-processing part of the set protocol; and processing the protocol data according to the protocol header, the protocol body and the protocol exception-processing part.

Abstract: Disclosed are a backlight brightness adjustment method and apparatus. The backlight brightness adjustment method includes the following steps: dividing a backlight area of a liquid crystal display (LCD) into multiple sub-areas, acquiring maximum pixel brightness M of each sub-area, and acquiring average pixel brightness A according to the maximum pixel brightness M; classifying the brightness into multiple brightness ranges, and separately adjusting duty cycles and drive currents of a backlight source in different brightness ranges according to the average pixel brightness A and the maximum pixel brightness M; determining, according to the maximum pixel brightness M of each sub-area, a brightness range of the sub-area, and acquiring an adjusted duty cycle and drive current that correspond to the brightness range of each sub-area; and correspondingly controlling illumination brightness of each sub-area by using the adjusted duty cycle and drive current. The present invention improves contrast of an LCD.

Abstract: Disclosed is a method for implementing a television theater mode, including: detecting playback content played by a playback terminal in real time when the playback terminal is in a playing status; when detecting that the playback terminal is playing a video, detecting current statuses of theater sound equipment, lighting equipment, and a curtain; sending a sound-and-light control command to a theater sound system and a curtain control system based on the current statuses of the theater sound equipment and the curtain, to adjust a current playback environment as a sound-and-light environment of the television theater mode; reading the video resource being played, determining a video image brightness change based on the read video resource, and sending the sound-and-light control command to the lighting control system, to adjust brightness of the indoor lighting equipment based the video image brightness change. Further disclosed is an apparatus for implementing a television theater mode.

Abstract: A method for quickly starting a television function is disclosed and includes: in response to receiving a start instruction triggered based on a start icon in a currently displayed startup page, starting a television function corresponding to the start instruction; updating the number of times of starts of the start icon corresponding to the start instruction; and when the updated number of times of starts is greater than a preset number of times, adding the start icon corresponding to the start instruction to a quick start interface corresponding to a quick start key of a remote controller. A device for quickly starting a television function is further disclosed. Thus, when the user has started a certain television function multiple times through the start icon in the startup page, the corresponding start icon will be added to the quick start interface corresponding to the quick start key.

Abstract: Disclosed an HDR television and a method for regionally dimming, the HDR television including a display screen, an offset calculation module, a constant-current driving and controlling module, a plurality of constant-current driving circuits, a plurality of light bars, an image processing MCU, and a memory; the display screen is divided into a plurality of regions, and the plurality of light bars are respectively distributed in the plurality of display screen regions; the image processing MCU is configured to output a grayscale signal; the offset calculation module is configured to acquire brightness information of each region of the display screen, calculate a reference offset of each region according to the brightness information of each region, and store the reference offset in the memory; the constant-current driving and controlling module is configured to read the reference offset in the memory.

Abstract: Provided are a method and an apparatus for processing audio data in a sound field. The method includes: acquiring the audio data in the sound field; processing the audio data through a preset restoration algorithm to extract audio data information about the sound field carried by the audio data; acquiring motion information about a target, and generating, through a preset processing algorithm, target-based sound field audio data based on the audio data information and the motion information about the target.

Abstract: The present invention discloses a controlling method and the system for smart home, each home appliance records a user's plurality of times of operations, and each sensor module in home appliance collects information on multiple times of working modes of each appliance, sends to the router wirelessly; the router analyzes busiest working periods and according working modes of each appliance, based on multiple times' working modes of each appliance and according working periods; router transmits control signals wirelessly to radio module installed in each appliance, to control each corresponding appliance run automatically in the working mode corresponding to the busiest working periods; the said controlling method and system operates simply, controls automatically without any manual operations, close to users' usage habits, and more humanized, it has freed a user's hands, avoided relying too much on mobile terminals, brought a great convenience to users.
