Detecting clock drift in networked devices through monitoring client buffer fullness

摘要

A digital media system (100) uses client buffer fullness reports (210) to detect clock drift between a clock on a host/source device (102,202) that delivers streaming media content and a clock on a client playback device (104,204) that receives the streaming media content. The system provides a reduction in playback interruptions during playback of streaming media content and a greater potential that "live" content encoded by a host/source device can actually be experienced as "live" content through playback on a client device.
