Abstract: Embodiments herein relate to a method for remapping data. In an embodiment, it is determined if a first memory block is faulty. A pointer is stored to the first memory block and a pointer flag of the first memory block is set when the first memory block is faulty. Data previously stored at the first memory block is written to a second memory block, where the pointer points to a location of the second memory block.

Abstract: The present invention relates to a method for scalably encoding and decoding a video signal. In an embodiment of the present invention, motion information, such as reference indices, motion vector, modes, etc., for an enhanced layer can be derived from a base layer, and a reference index for an image block in the enhanced layer is determined using median criterion based upon the base layer. A reference index for a block, having the most pixels corresponding to those of the image block, in the base layer is selected as the reference index for the image block, and the nearer reference index is selected if more than one block in the base layer have the same pixels corresponding to those of the image block. And, a motion vector for the base layer block related to the selected reference index is selected as the motion vector for the image block.

Abstract: A method and an apparatus of decoding a video signal are provided. The present invention includes the steps of parsing first coding information indicating whether a residual data of an image block in the enhanced layer is predicted from a corresponding block in the base layer, from the bitstream of the enhanced layer, and decoding the video signal based on the first coding information. And, the step of parsing includes the step of performing modeling the first coding information based on second coding information indicating whether prediction information of the corresponding block in the base layer is used to decode the image block in the enhanced layer. Accordingly, the present invention raises efficiency of video signal processing by enabling a decoder to derive information on a prediction mode of a current block in a decoder instead of transferring the information to the decoder.

Abstract: Disclosed herein is a method of encoding video signals. The method includes creating a bit stream of a first layer by encoding the video signals, and creating a bit stream of a second layer by encoding the video signals based on the first layer. When residual data, corresponding to an image difference, within the first layer, is up-sampled and used for the encoding of the second layer, the residual data is up-sampled for each block that is predicted based on motion compensation.
