1results about How to "Reduce queuing delay" patented technology

This invention discloses a low-latency UAV-assisted dynamic distribution method for panoramic video streams based on viewport prediction, belonging to the interdisciplinary field of mobile communication and immersive multimedia transmission. By constructing a multi-level forward-looking virtual queue model, future viewport data requests are mapped to current weighted accumulated potential energy, thereby driving the system to perform traffic temporal shaping when channel conditions are favorable. In other words, through proactive resource scheduling, future transmission tasks are shifted to the present for completion, achieving a proactive service mode for data waiting for users. Simultaneously, in conjunction with a trap-aware hierarchical backtracking optimization strategy, this invention can guide UAVs to actively avoid local optimal deadlocks, ensuring that the optimal air-to-ground transmission link is maintained in dynamic environments, thereby fundamentally eliminating queuing time and guaranteeing a low-latency, smooth playback experience for panoramic video.
