Document Type and Number:
WIPO Patent Application WO/2005/109900
Kind Code:
A1
Abstract:
Methods and apparatus for encoding and decoding multimedia frames are presented. The method comprises encoding a set of acquisition frames including a viewable frame, each frame comprising one or more intra-coded portions and one or more inter-coded portions, wherein the act of encoding the intra-coded portions comprises positioning the intra-coded portions such that when the intra-coded portions of the set of acquisition frames are combined, a complete intra-coded composite frame is formed. The act of encoding the inter-coded portions comprises predicting the inter-coded portions 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.
