A method of measuring MPEG PCR jitter, frequency offset and drift rate uses a selectable, constant measurement bandwidth over non-uniform PCR arrival times and a variable PCR rate. The selectable, constant measurement bandwidth is fixed at a frequency that demarcates between jitter and wander. For each...http://www.google.com.tw/patents/US6650719?utm_source=gb-gplus-share專利 US6650719 - MPEG PCR jitter, frequency offset and drift rate measurements
