Alibaba signs 6-year AI deal with Uefa for sports

360-degree Replay Technology (Real-Time 360º Replay):

• Integrates computer vision, AI motion recognition, and real-time rendering technologies.
• Utilizes multi-camera HD video capture and deep learning model analysis to precisely calculate key athletic metrics such as jump height, release angle, ball trajectory, entry angle, and apex of the parabolic arc.
• Overlays these data animations onto live broadcasts with low latency and high accuracy.
• Features 'Multi-Angle Replay' for freezing time and space with a 360-degree surround view, and 'Spacetime Slices' which combines multiple phases of an athlete's movement into a single composite image for enhanced technical understanding.
• An AI algorithm is used to separate athletes from complex backgrounds (e.g., snow and ice) to enable accurate three-dimensional reconstructions of key moments.
• The system can generate these 3D reconstructions in 15-20 seconds, making it suitable for live broadcast use.
• The entire process leverages cloud computing, AI processing, and real-time 3D rendering.

Qwen AI Model:

• Qwen is a family of large language models (LLMs) and multimodal models (MLLMs) developed by Alibaba Cloud.
• Designed to excel in reasoning, coding, multimodal understanding, and multilingual capabilities, supporting over 100 languages.
• Employs advanced architectures, including Mixture-of-Experts (MoE) designs, for state-of-the-art performance.
• The latest Qwen3 models feature hybrid thinking modes ('Thinking' for complex logical reasoning and 'Non-Thinking' for efficient general dialogue), allowing flexible control over reasoning performance, speed, and costs.
• The Qwen family includes specialized models like Qwen-VL (visual language model), Qwen-TTS (text-to-speech), Qwen-Audio, and Qwen3-Omni (capable of processing text, audio, and vision simultaneously).
• In sports, Qwen powers the Automatic Media Description (AMD) System, which automatically identifies athletes and key moments, generates event descriptions, and tags video assets, significantly reducing manual processing time.
• It also underpins 'Olympic AI Assistants' for fan engagement (multilingual conversational support, real-time event information) and internal operations (document retrieval for National Olympic Committees).
• A proprietary AI model for NBA China has been developed based on Alibaba's Qwen series of foundational models.
