    Abstract: The present invention discloses an inter-frame predictive coding method and a coder. Inter-frame predictive coding is sequentially performed on frames in multiple groups of pictures by using a group of pictures as a unit; a correlation between the reference B frame and a GPB frame in the same group of pictures is used; and when the maximum depth of the CTU in the same position in the GPB frame is smaller, a quantity of mode decisions performed on the CTU in the reference B frame may be relatively small, so that an objective of reducing complexity of an inter-frame predictive coding process of the reference B frame is achieved.

    Abstract translation: 本发明公开了一种帧间预测编码方法和编码方法。 通过使用一组图像作为一个单元，对多组图像中的帧顺序执行帧间预测编码; 使用同一组图像中的参考B帧和GPB帧之间的相关性; 并且当在GPB帧中相同位置的CTU的最大深度较小时，在参考B帧中对CTU执行的模式决定的数量可能相对较小，从而降低帧间复杂度的目标 实现了参考B帧的预测编码处理。

    Abstract: This application provides an intelligent control apparatus, including: a control circuit and a detection and heating circuit. The detection and heating circuit includes a detection and heating material. When the detection heating material works in a detection mode, the detection and heating circuit obtains a bioelectric signal of a user by using the detection and heating material. The control circuit instructs, according to the bioelectric signal, the detection heating circuit to switch a working mode of the detection and heating material to a heating mode; and instructs the detection and heating circuit to determine heating duration and/or a heating temperature of the detecting and heating material. The apparatus may be used in the field of artificial intelligence. Through control of the control circuit, the detection heating material can have both detection and heating functions. Intelligent perception of a state of the user is implemented by detecting of the bioelectric signal.

    Abstract: This application provides a multi-view distance measurement method and an electronic device, and relates to the field of electronic technologies. Because positions of regions of interest of an electronic device, for example, a vehicle, vary with different scenarios, a distance measurement capability of the electronic device needs to match the regions of interest at different positions. According to the multi-view distance measurement method provided in this application, an appropriate relative pose is selected from a plurality of preset relative poses based on driving information, and then relative poses of cameras are adjusted, so that a distance measurement capability of the camera matches a region of interest, to implement distance measurement.

    Abstract: This application provides a signal transmission method. The method includes: transmitting an SRS of the first network from three antennas: a third antenna, a fourth antenna, and a fifth antenna in turn; and inputting the SRS and a second signal of the second network to a combiner, where the combiner combines the two signals and then transmits a combined signal from a multiplexed first antenna. In this way, the SRS is transmitted by using four paths in turn. This can ensure that transmission of the second signal is not interrupted in a process of transmitting the SRS of the first network by using the four paths in turn, so that a service of the second network is not interrupted.

    Abstract: A data interaction method is provided, which includes: sending simultaneously an address detection request for a UDP channel and an address detection request for a TCP channel; and when both address detection for the UDP channel and address detection for the TCP channel fail, sending an address detection request for an HTTP channel; when detection of at least one channel succeeds, collecting two types of addresses corresponding to each channel in the at least one channel; performing address exchange and address matching with a peer client host; and performing channel connectivity detection based on matched addresses, and selecting a channel with a highest priority from channels on which connectivity detection is successful for data interaction with the peer client host. Therefore, efficiency of traversing a NAT host during address detection is improved.
