Abstract: A streaming media resource downloading method includes: determining that a first media file is a to-be-downloaded media file according to first network bandwidth, where the first media file is included in a streaming media resource corresponding to the first network bandwidth, and the first media file includes N data blocks; and after an (n−1)th data block in the first media file is downloaded, and before an nth data block in the first media file is downloaded, determining a length of the to-be-downloaded nth data block according to network bandwidth reduction times in an executed first media file downloading process, where 1≤n≤N. Therefore, a length of a to-be-downloaded data block is adjusted according to the network bandwidth reduction times in the first media file downloading process so that video playing can better adapt to a bandwidth change, and streaming media resource switching times are reduced.

Abstract: A method includes a device in an area 1 that requests a ultra-wideband (UWB) base station in the area 1 to measure an initial position, and starts inertial measurement unit (IMU) measurement. The device moves to an area 2, and the device requests to measure distances between each UWB base station in the area 2 and at least three locations. The device returns to the area 1, and requests the UWB base station in the area 1 to measure an end point position. The device corrects coordinates of the device in the area 2 calculated using data obtained through the IMU measurement based on the measured end point position. Calculate the coordinates of each UWB base station in the area 2 based on the corrected coordinates in the area 2 and the measured distances between each UWB base station and the device in the area 2.
