Bits for the current picture are then allocated based on the complexity of future pictures in the sliding window. After encoding the current picture according to the sophisticated compression standard, the target bits of and the picture complexity in the sliding window, as well as the trans-factor, are updated as the window is moved by one picture.Type: GrantFiled: December 10, 2002Date of Patent: August 29, 2006Assignee: Tut Systems, Inc.Inventors: Guoyao Yu, Zhi Zhou, Charles H.
