Abstract: This application provides a video picture decoding and encoding method and a video picture decoding and encoding apparatus. When it is determined that a merge or skip mode is used, if it is determined through decoding that an MMVD indicator is true, a triangle PU indicator may not be coded.

This reduces a quantity of used coding resources, and can reduce bit overheads of a bitstream.

Existing magnetic coils on a mobile device (e.g., for charging or communication) may be re-used for distance measurements that are supplemented by the RF measurements. Any device antenna may provide measurements to a machine learning model that determines a region in which the mobile device resides, based on training measurements in the regions.
