Abstract: A clock rate used in rendering broadcast streaming audio/video data is adjusted to converge on a clock rate associated with broadcasting the streaming data. The clock rate is adjusted by monitoring the buffer depth associated with a receive buffer that stores the incoming streaming data. The buffer depth provides an estimate of clock drift between the two clock rates. From the estimate of clock drift, the clock rate used in rendering broadcast streaming data is adjusted to avoid the clock drift causing skips or pauses in the rendered audio/video data.

Abstract: The present invention provides a unique system and method that mitigates viewing potentially offensive or spam-like content such as in a preview pane. In particular the system and/or method involve assigning a junk score to a message and then determining an appropriate treatment of the message based on its junk score. Messages with junk scores that exceed a challenge threshold can be hidden from a message listing such as in the user's inbox while a challenge is sent to the message sender. Upon receiving a validated and correct response from the sender, the message can be released or revealed to the user in the user's inbox. Content associated with messages with junk scores that exceed a blocking threshold can be blocked from view in a preview pane. Explicit user input can be required to unblock the content.
