Patent ID: 8483277

Claim:
A method for temporal decomposition and reconstruction of an input video signal that uses a prediction process and an update process in a framework of motion compensated temporal filtering (MCTF), motion information used for the update process being derived from motion information used for the prediction process, the method employing a block based video codec composed of an encoder and a decoder, the method comprising: receiving a first picture, a second picture, and a third picture in a group of pictures from the input video signal; performing the prediction process on the second picture utilizing the first picture and the third picture; receiving, after performing the prediction process, a fourth picture in the group of pictures; performing, after receiving the fourth picture, a first part of the update process on the second picture utilizing the fourth picture; receiving, after performing the first part of the update process, a fifth picture in the group of pictures; and performing, after receiving the fifth picture, a second part of the update process on the second picture utilizing the second picture.
