Abstract: An image display method for a head mounted display (300) is disclosed. The head mounted display (300) includes a first display screen (3011) and a second display screen (3012). In a first time period S1 of an ith display cycle T, the head mounted display (300) displays an ith frame of a first image on the first display screen (3011). After stopping displaying the ith frame of the first image, the head mounted display (300) displays an ith frame of a second image on the second display screen (3012) in a second time period S2 of T. After the second time period, no image is displayed on the first display screen (3011) and the second display screen (3012). According to the method, a peak current of a device when displaying an image can be reduced.

Abstract: A multicast data transmission method includes: determining, by a first BFIR in a first BIER domain, a BIFT-id and a bitstring that correspond to multicast data in a second BIER domain, where the BIFT-id is determined based on at least an SI to which a BFR-id of a first BFER belongs and a BSL supported by the first BFER, and the first BFER is a BFER in the second BFER domain that is used to receive the multicast data; encapsulating the multicast data into a BIER data packet, where a BIER header of the BIER data packet includes the BIFT-id and the bitstring that correspond to the multicast data in the second BIER domain; and finally sending the labeled BIER data packet to a second BFIR, where the label is a label corresponding to a prefix of the second BFIR.

Abstract: A first device obtains an advertising parameter used by a second device to send an advertising data packet, where the advertising parameter includes an advertising window and an advertising interval. The first device determines, based on the advertising window and the advertising interval by using a preset scanning model, a target scan parameter used by the first device, where the target scan parameter is a scan parameter used by the first device when power consumption of the first device is a preset threshold and a scan-to-discover time period satisfies a preset condition. The target scan parameter includes a target scan window and a target scan interval. The first device performs scanning based on the target scan window and the target scan interval.

Abstract: The present disclosure relates to the field of electronic devices and provides an application switching method, apparatus, and a graphical user interface to resolve a problem that multi-task switching has a relatively high requirement on the hardware of an electronic device. The application switching method includes: detecting a touch pressure value that is generated by a touch operation when a target region of a touchscreen is touched; when detecting that the touch pressure value is greater than a preset threshold, generating a first display window in a current display interface of an electronic device, and presenting a first application in the first display window according to a preset rule; and switching the current display interface to a display interface of the first application if detecting an enable signal for the first application, where the current display interface is different from the display interface of the first application.

Abstract: A method, a device, and a system for transmitting a multicast packet are provided. The method includes: when a device that is in a source subnet and that is connected to a core network receives a multicast packet of a target multicast group, determining addresses of devices that are in a plurality of destination subnets corresponding to the target multicast group and that are connected to the core network, replicating the multicast packet, to obtain a plurality of multicast packets whose quantity is equal to a quantity of the plurality of destination subnets, separately adding outer encapsulation to each multicast packet, and forwarding the multicast packet to which the outer encapsulation is added, where a destination address in the outer encapsulation is an address of a device that is in each destination subnet and that is connected to the core network.
