Real-time content-based adaptive streaming of sports videos

We present a real-time software system for filtering live video content and then adoptively streaming the video over resource limited networks or devices. The rate adaptation is content-based and dynamically varied according to the event structure and the video content. The system includes a content analysis module for detecting important segments in the video, a variable-rate encoding module, and a buffer management module for streaming the variable rate video over low bandwidth networks. We have implemented a prototype system, which performs real-time content adaptation for tennis and baseball with promising results.
