Assigning a program clock reference (PCR) value to a PCR packet. A theoretical input time and a theoretical output time is determined for a PCR packet received by a Remote PHY device (RPD) or a Remote MACPHY Device (RMD). A corrected PCR value is assigned to the PCR packet, based at least in part, on the theoretical output time and the theoretical output time. Then, the PCR packet having the corrected PCR value is transmitted to customer premises equipment (CPE) in a Converged Cable Access Platform (CCAP). Assigning a corrected PCR value to the PCR packet may be performed without learning an encoding rate associated with a program to which the PCR value is assigned.
