摘要： Systems and methods for adaptively adjusting a slew rate of a dejitter buffer in a remote device in a distributed access architecture. The slew rate may be adjusted based on measurements of a fullness state of a buffer made over time. The measurements may be used to calculate a frequency offset value between the rate at which data leaves the buffer relative to the rate at which data enters the buffer and/or used to calculate a current working depth of the buffer. The adaptive slew rate adjustments may be based on the frequency offset value and/or the current working depth.

摘要： Systems and methods for providing timing information from a R-MACHPHY device to a video core while the R-MACPHY device receives video data from the video core while operating in asynchronous mode. In some embodiments, the R-MACPHY device may alternately and selectively configure its mode of operation to alternate between synchronous mode and asynchronous mode, and provide the timing information to the video core when it switches to asynchronous mode.
