A video system includes a decoder and a scaler. The decoder tracks a video signal, generates a synchronization signal and a frequency offset signal, decodes the video signal, and outputs a decoded signal in accordance with the synchronization signal. The scaler generates a frequency control signal in accordance with the frequency drift signal, generates an output clock signal in accordance with the frequency control signal, generates a scaled signal in accordance with the decoded signal, and outputs a display signal in accordance with the scaled signal and the output clock signal.
