METHOD FOR ENCODING VIDEO DATA

摘要

A method for encoding video data that are structured into groups of frames (GOF), wherein motion compensated temporal filtering (MCTF) of frames on a plurality of temporal decomposition levels based on a lifting scheme is used, works in two steps. In the first step, different possible partitionings of a group of frames are evaluated, whereby for each partitioning a cost value being a weighted sum of inter-partition backward prediction steps and/or backward update steps is generated. Then the partitioning with the least cost is implemented by cutting certain steps, e.g. inter-partition backward prediction steps and corresponding forward update steps.
