Abstract:
1. A method for encoding or decoding a video signal, the method comprising: deriving position information of a base layer macroblock in a base layer based on position information of a virtual macroblock in a virtual base layer, the virtual macroblock corresponding to the current macroblock in the enhanced layer, wherein the base layer macroblock is a field macroblock and the current macroblock is a frame macroblock; obtaining texture prediction information of the current macroblock in the enhanced layer when a block type of the base layer macroblock corresponding to the position information of the base layer macroblock is an intra-coded macroblock type; and obtaining motion prediction information of the current macroblock in the enhanced layer when the block type of the base layer macroblock corresponding to the position information of the base layer macroblock is an inter-coded macroblock type, wherein the obtaining the texture prediction information comprises:
