Abstract
Briefly, a system time clock (STC) recovery apparatus includes an STC counter that receives a program clock reference (PCR) signal. The STC recovery apparatus also includes a phase lock loop that generates an STC signal having an STC frequency and a fractional divider that generates a modified STC signal by adjusting the STC frequency of the STC signal such that the modified STC signal is provided to the STC counter. The STC clock recovery apparatus further includes a register, such as any suitable memory, which stores a target frequency value and a source frequency value. The target frequency value is the value of the target frequency for the modified STC signal and the source frequency value is the value of the frequency of the STC signal from the phase lock loop.
