A biaxially oriented polyolefin multilayer film having a skin layer having oil-absorbing voids is disclosed. The method encapsulates the content in accordance to an Internet Protocol. The circuitry is further configured to increment a counter if the phase difference is in a first direction, decrement the counter if the phase difference is in a direction opposite to the first direction, and convey a phase correction signal to the clock generator if an output value of the counter meets or exceeds a threshold.
