Abstract
A random access point can be generated in a stream of coded digital pictures containing a plurality of predictive coded frames in which one or more subsections of each frame are intra coded. A patch frame can be formed from intra-coded subsections in identified consecutive predictive-coded frames. The patch frame can be used as a synthetic random access point.
