ABSTRACT:
A video encoding scheme employs progressive fine-granularity layered coding to encode video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video. Some of the enhancement layers in a current frame are predicted from at least one lower quality layer in a reference frame, whereby the lower quality layer is not necessarily the base layer.
