The application discloses a deep learning-based adaptive code rate control method and system for ultra-high-definition video, and relates to the technical field of video coding and transmission. The application solves the problem that traditional coding behavior is prone to causing data congestion or frame loss due to network space fluctuation. The application accurately calculates characteristic flow by comprehensively considering the current total buffer amount of network nodes and the video frame flow to be processed, further determines the network interval required by the processing period, determines the data amount that can be processed in the processing period based on the network interval, and precisely controls the interaction flow of multiple path nodes by analyzing the past data characteristics of the video stream path nodes and other nodes. The application not only can reasonably allocate network resources to prevent data congestion of network nodes due to excessive flow, but also can ensure that the video code rate reaches the best state in the adjustment and verification process, thereby improving the video transmission efficiency and quality.

A sensor data processing apparatus can be coupled to multiple image sensors of different types. The apparatus adjusts frame transmission rates based on the number of sensors and type of image data sourced by the sensors to optimize utilization of bandwidth on a number of transport channels. The apparatus can be configured to transport selected frames in the image data that are identified as critical frames at a higher rate than non-selected frames in the image data.

The function of an unmanned aerial vehicle (UAV) may depend on location. In some embodiments, the digital audio communication channel is synchronized and multiplexed with a high definition video stream captured by a user-controlled remote UAV. The accompanying audio stream is used to provide supplemental and rich information to end users who are controlling the action of the remote UAV. The system can be used for providing virtualized tourism experience at hot places such as historical residence sites, wild animal protection areas and landmark tourism destinations. In some embodiments, a virtual three-dimensional geometry having a boundary surface typically referred to as a geo-fence and a concomitant control system restricts the flight path of a remotely driven UAV to an internal geometry.
