Hybrid temporal-SNR fine granular scalability video coding

A method for coding video data, comprising the steps of coding a portion of the video data to produce base layer frames;

• generating motion compensated residual images from the video data and the base layer frames;
• coding the motion compensated residual images to produce temporal enhancement frames;
• generating residual images from the video data, the base layer frames and the temporal enhancement frames;
• and
• coding the residual images using a fine granular coding technique to produce quality enhancement frames.

A method of decoding a video signal including a base layer and an enhancement layer, comprising the steps of:

• decoding the base layer to produce video frames;
• decoding the enhancement layer to produce motion vectors;
• performing motion compensation on the video frames according to the motion vectors to produce additional video frames;
• and
• combining the video frames and the additional video frames to form a video sequence.
