摘要： Beyond-visual-line-of-sight (BVLOS) control of drones is enhanced using wireless communication via a cellular network. In an example system, a drone and a remote control station are configured to communicate via a 5G network. Drone control is further enhanced with extended reality (XR) display. Video stream data captured by the drone is replaced, supplemented, and/or overlaid with XR visual data in an XR environment. The XR visual data corresponds to a perspective from a virtual location in the XR environment that mirrors a real-world location of the drone. This lightens constraints and requirements associated with the network communication of video stream data from the drone for BVLOS control of the drone. Drone control is further enhanced with voice command capability. A user vocally utters a coarse-resolution or abstract command, and a drone control station translates the utterance into a sequence of fine-resolution drone commands that implement the vocally-uttered command.

摘要： Approaches to preventing degraded video presentation use reference video quality measurement feedback from a video decoder node that is receiving live action video streams from a video encoder across a cellular network. A reference video stream is encoded along with the live action video streams, and the video decoder node compares the decoded reference video stream with a local copy to determine video quality. The video decoder node provides video encoding parameter feedback for adjusting the encoding and/or provides cellular network feedback for adjusting a transmission parameter for data traffic through the cellular network (from the video encoder node to the video decoder node). Solutions are disclosed for implementation at the video encoder, at the video decoder, and within the cellular network. For example, different compression codecs may be specified, and bit rates, frame, rates, key frame intervals, and/or bit depth may be automatically (immediately) adjusted without requiring human intervention.
