METHOD AND APPARATUS FOR GENERATING A MOTION VECTOR

摘要

One embodiment provides a method of generating a motion vector associated with a current block in a first picture layer. In this embodiment, motion vector information for a block in a second picture layer is obtained. The second picture layer has lower quality pictures than pictures in the first picture layer, and the block of the second picture layer is temporally associated with the current block in the first picture layer. Motion vector difference information associated with the current block in the first picture layer is also obtained. The motion vector associated with the current block in the first picture layer is generated based on the obtained motion vector information and the obtained motion vector difference information.
