Abstract
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.
