In a picture synchronization circuit, a decoding time stamp value of an input picture is compared with a system time clock count value at the moment a picture is input. When the decoding time stamp value is larger than the system time clock count value, and when a difference between the decoding time...http://www.google.com.hk/patents/US6028648?utm_source=gb-gplus-share專利 US6028648 - Picture synchronization circuit and method therefor
