Abstract

The present invention is directed to fine granular coding technique that includes both quality and temporal scalability. This is accomplished by utilizing a hybrid temporal/SNR scalability structure that is readily adaptable to fine granular coding techniques. In one example of this structure, temporal enhancement frames and FGS enhancement frames are included in a single enhancement layer. In another example, two distinct enhancement layers are used to achieve the hybrid temporal-SNR scalability. The two layers include a temporal scalability layer to achieve the temporal enhancement for the base-layer (i.e., better motion), while an FGS layer is used to improve the quality SNR of the base-layer and/or the temporal-scalability enhancement layer.
