METHOD AND APPARATUS FOR DYNAMIC DETERMINATION OF FRAMES REQUIRED TO BUILD A COMPLETE PICTURE IN AN MPEG VIDEO STREAM

摘要

A method for dynamically determining frames required to build a complete picture in an MPEG video stream (60) includes decoding (70) an order of frames in the MPEG video stream (80) according to a dependency vector model. The dependency vector model is configured for determining a dependency vector (102) as a function of the decode order video stream (80) for seamless operation over several types of MPEG streams. The method also includes performing frame accurate representations (131) of the MPEG stream in a bidirectional fashion as a function of the dependency vector determined according to the dependency vector model.
