METHOD AND APPARATUS FOR DEQUANTIZATION OF A VIDEO SIGNAL

摘要

In one embodiment, a motion vector for a current block is generated based on motion vector information for a block in a second picture layer and motion vector difference information associated with the current block. The second picture layer has lower quality pictures than pictures in the first picture layer, and the block of the second picture layer being temporally associated with the current block in the first picture layer. The current block is reconstructed using the generated motion vector and a reference picture.
