Abstract: Systems, methods, and non-transitory computer-readable media can be configured to perform operations comprising determining capabilities associated with a plurality of devices in a communication session, determining one or more media channels for transmission of media between the plurality of devices based on the capabilities, and facilitating the transmission of media between the plurality of devices via the one or more media channels.

Abstract: The application discloses a method and apparatus for spatial data processing, and relates to the technical field of data processing. One specific implementation mode of the method comprises: acquiring at least two types of spatial data sets; constructing spatial indexes for the spatial data sets; constructing spatial geometric groups in accordance with the spatial indexes and the at least two types of spatial data sets; placing the spatial geometric groups into a message queue, and subjecting the spatial geometric groups to a spatial correlation calculation by idle threads, which are threads for processing spatial data in the spatial data sets. The implementation mode can effectively balance calculation resources, reduce consumption of the calculation resources, and meanwhile improve a processing efficiency of spatial data.

Abstract: The present invention discloses a method, apparatus, device and computer-readable medium for trajectory compression, and relates to the technical field of computers. One specific implementation of the method comprises: screening, among trajectory points of a traveling trajectory, reserved trajectory points of the traveling trajectory according to deviation degrees of the trajectory points from roads; determining, in conjunction with traveling periods of the reserved trajectory points, the reserved trajectory points as key trajectory points, the traveling period being a time interval from a previous trajectory point of the reserved trajectory point to a next trajectory point of the reserved trajectory point; adding the starting point of the traveling trajectory, the key trajectory points and the ending point of the traveling trajectory to a compressed trajectory so as to compress the traveling trajectory.
