Abstract: An audio data transmission method. An electronic device transmits audio data to a first earbud of a TWS headset by using a first CIS of a first CIG, and transmits audio data to a second earbud of the TWS headset by using a second CIS of the first CIG. The electronic device determines that the TWS headset is switched from a double-earbud mode (namely, a mode in which the first earbud and the second earbud are used together as audio input/output devices of the electronic device) to a first single-earbud mode (namely, a mode in which the first earbud is independently used as an audio input/output device of the electronic device). In response to the determining, the electronic device deactivates the second CIS, stops transmitting audio data to the second earbud by using the second CIS, and continues transmitting audio data to the first earbud by using the first CIS.

Abstract: A refresh rate switching method and an electronic device are provided. In the method, the electronic device dynamically switches a corresponding screen refresh rate by determining whether a current display image is a high frame rate scenario or a standard frame rate scenario. In the high frame rate scenario, a relatively high screen refresh rate is used to support a high display frame rate. In this way, a user can obtain experience of the high display frame rate, and the display image is smooth without motion blur. In the standard frame rate scenario, a default low screen refresh rate is used to reduce power consumption of an entire system.

Abstract: A packet processing method and device are provided, to save CPU resources consumed by parsing a packet. The method includes: parsing, by an intelligent network interface card, a received first packet to obtain an identifier of the first packet; updating, by the intelligent network interface card, a control field of a first memory buffer based on the identifier of the first packet; storing, by the intelligent network interface card, a payload of the first packet or a packet header and a payload of the first packet into the first address space through DMA based on an aggregation position of the first packet; aggregating, by a host, the first address information and at least one piece of second address information based on an updated control field in the first mbuf; and reading, by a virtual machine, address information, to obtain data in an address space indicated by the address information.

Abstract: Embodiments of this application provide a Bluetooth connection method, a system, and an electronic device. In the method, when a communication connection between an electronic device and a vehicle head unit is disconnected, the electronic device starts to scan a Bluetooth advertising signal. When a user carrying the electronic device is close to the vehicle head unit, the electronic device may obtain, through scanning, a Bluetooth advertising signal sent by the vehicle head unit. When obtaining, through scanning, the Bluetooth advertising signal sent by the vehicle head unit, the electronic device may start a vehicle manufacturer application when the vehicle manufacturer application is cleared by a system. The electronic device may reconnect to the vehicle head unit through Bluetooth by using the vehicle manufacturer application and a Bluetooth chip. Embodiments of this application can improve convenience of unlocking in a scenario in which a vehicle is insensibly unlocked.

Abstract: This application provides a gesture recognition method, and relates to the field of man-machine interaction technologies. The method includes: extracting M images from a first video segment in a video stream; performing gesture recognition on the M images by using a deep learning algorithm, to obtain a gesture recognition result corresponding to the first video segment; and performing result combination on gesture recognition results of N consecutive video segments including the first video segment, to obtain a combined gesture recognition result. In the foregoing recognition process, a gesture in the video stream does not need to be segmented or tracked, but phase actions are recognized by using a deep learning algorithm with a relatively fast calculation speed, and then the phase actions are combined, so as to improve a gesture recognition speed, and reduce a gesture recognition delay.

Abstract: A distance measurement method. A first electronic device establishes a communication connection to a second electronic device. The first electronic device receives a distance measurement instruction. The first electronic device receives a plurality of groups of sound wave signals sent by a speaker in the second electronic device. Then, the first electronic device determines, based on the plurality of groups of sound wave signals, a sending moment, and a sound wave velocity, a real-time distance between the first electronic device and the second electronic device when each group of sound wave signals are received by the first electronic device. Finally, the first electronic device continuously refreshes and displays the real-time distance between the first electronic device and the second electronic device that is obtained through calculation to improve display precision.
