Abstract

There are provided a method and apparatus for adaptive Group of Pictures structure selection. The apparatus includes an encoder (100) for encoding a video sequence using a Group of Pictures structure by performing, for each Group of Pictures for the video sequence, picture coding order selection, picture type selection, and reference picture selection. The selections are based upon a Group of Pictures length.
