摘要
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 same or lower quality layer in a reference frame, whereby the lower quality layer is not necessarily the base layer. Use of multiple reference layers of different quality results in occasional fluctuations in the encoded image data. The video encoding scheme efficiently eliminates such fluctuations by predicting higher quality data from the lower quality data encoded in the base layer and a low quality enhancement layer.
