Abstract: A media processing device includes a transmission interface to transmit an output media stream based on an output clock signal, whereby output video stream includes a representation (e.g., a transcoded representation) of an input media stream. The media processing device further includes a clock drift module to generate a stream of average clock drift values representing differences between a local system time clock and clock references of the input media stream and a proportional-integral-derivative (PID) controller to filter the stream of average clock drift values to generate a stream of filtered average clock drift values. The media processing device further includes a clock adjust module to adjust the output clock signal based on the stream of filtered average clock drift values.
