Patent ID: 7991053

Claim:
A method of decoding a sequence of frames, comprising: receiving data representing a set of acquisition frames, enabling random access to the sequence of frames, including a viewable frame, each acquisition frame comprising one or more intra-coded portions and one or more inter-coded portions, wherein the intra-coded portions are positioned such that when the intra-coded portions of the set of acquisition frames are combined, a complete intra-coded composite frame is formed, further wherein the inter-coded portions are predicted such that the viewable frame is comprised of intra-coded portions and inter-coded portions that are directly or indirectly predicted from the intra-coded portions of the set of acquisition frames, wherein the set of acquisition frames provides a random access point for decoding the sequence of frames, wherein predicting the inter-coded portions of the set of acquisition frames comprises backward prediction to provide the random access point to the sequence of frames; decoding the intra-coded portions of the set of acquisition frames; and decoding the inter-coded portions of the viewable frame.
