content-adaptive transmission of reconstructed soccer goal events over low bandwidth networks
This paper presents a content-adaptive system for streaming reconstructed soccer goal events over networks with bandwidth limited to 1.5Mbps or below. The reconstruction module analyzes a soccer video to produce corresponding panoramic field model with localized motion trajectories to provide tactic analysis for user's better comprehension of the goal events. The transmission module designs 3 schemes for different bandwidth conditions (150Kbps-1.5Mbps), (56-150Kbps), and (<56Kbps). Each scheme can choose dynamically the video content, viewing quality and where the reconstruction happens based on the network conditions and computational power of connected devices. We demonstrate the effectiveness and scalability of our system in experimental results of adaptive transmission two soccer goal events under three typical bandwidth conditions.
