DETECTION OF CLOCK DRIFT IN NETWORKED DEVICE THROUGH MONITORING OF CLIENT BUFFER FULLNESS

摘要

PROBLEM TO BE SOLVED: To provide a method for detecting clock drift between a host device and a client device, that deliver streaming content to a client playback device.

SOLUTION: A buffer monitor on the client device monitors a client buffer and generates buffer occupied amount reports that indicate the level of data in the client buffer. The buffer monitor sends the buffer occupied amount reports to a clock drift detection and recovery component on the host device. The clock drift detection and recovery component discriminates from the buffer occupied amount reports the extent of clock drift between the client device clock and the host device clock.
