Claim Text:
1. A method for encoding or decoding a video signal with a decoding apparatus, the method comprising: deriving, with the decoding apparatus, position information of a reference block in a base layer based on position information of a virtual reference block in a virtual base layer, the virtual reference block corresponding to the current block in an enhanced layer, wherein the reference block is a field block and the current block is a frame block; obtaining, with the decoding apparatus, texture prediction information of the current block in the enhanced layer when the reference block corresponding to the position information of the reference block is an intra-coded block; and obtaining, with the decoding apparatus, motion prediction information of the current block in the enhanced layer when the reference block corresponding to the position information of the reference block is an inter-coded block, wherein the motion prediction information of the current block in the enhanced layer includes a motion vector and a reference index, wherein obtaining the texture prediction information comprises: wherein obtaining the motion prediction information comprises: obtaining, with the decoding apparatus, a vertical component of the motion vector of the current block in the enhanced layer by multiplying a vertical component of a motion vector of the reference block by two; and obtaining, with the decoding apparatus, the reference index of the current block in the enhanced layer by multiplying a reference index of the reference block by two.
