Real-Time Content-Based Adaptive Streaming of Sports Videos

Shih-Fu Chang, Di Zhong, and Raj Kumar


In this paper, we present a real-time software system for filtering live video content and then adaptively 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.
