New Instant Replay System for Winter Sports

Alibaba Cloud is deploying an upgraded Real-Time 360º Replay system for the Milano Cortina 2026 Winter Games, designed to provide immersive replays with fluid camera movement and stroboscopic visual effects. This advanced system utilizes an AI algorithm capable of separating athletes from complex backgrounds, such as snow and ice, to generate three-dimensional reconstructions of key moments within 15 to 20 seconds, making it suitable for live broadcast integration.
Enhanced Visual Capabilities

The upgraded Real-Time 360º Replay system incorporates several new features to enhance the viewing experience. Building upon the BulletTime effects introduced previously, which allow for frame-freezing and slow-motion playback, the system now includes a Spacetime Slices capability. This new feature visualizes multiple phases of an athlete's movement within a single composite image, offering viewers a more detailed understanding of technique and performance.
Broad Sport Application

This innovative replay technology will be implemented across a wide range of winter sports and disciplines at the Milano Cortina 2026 Games. Specifically, it is set to be deployed in 17 different sports and disciplines. Notable examples of sports that will benefit from this system include ice hockey, freestyle skiing, figure skating, and ski jumping, ensuring dynamic and detailed replays for diverse athletic events.
AI-Powered Reconstruction

The core of the Real-Time 360º Replay system's capability lies in its sophisticated AI algorithm. This algorithm is specifically trained to distinguish athletes from challenging environments, such as the varied textures of snow and ice. By isolating the athlete, the system can then process the visual data to create accurate three-dimensional reconstructions of critical actions and moments during competitions, all achieved within a remarkably short timeframe suitable for immediate broadcast.
