The initialized reference picture list is modified based on modification information representing how to assign an inter-view reference index in the initialized reference picture list. A prediction value of a macroblock in the random access picture is determined based on the modified reference picture list, and the macroblock is decoded using the prediction value. | 12-16-2010 |

| 20110019739 | Method for modeling coding information of a video signal to compress/decompress the information - 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. | 01-27-2011 |

| 20110110434 | Method for decoding and encoding a video signal - A method for decoding/encoding a video signal using an inter layer prediction process is disclosed. The method for decoding a video signal including several layer information includes: a) acquiring a first prediction signal for a current block of an enhancement layer and a residual signal based on at least a base layer block; b) smoothing the sum of the first prediction signal and the residual signal, and generating a second prediction signal for the current block; and c) reconstruction the current block based on the second prediction signal. Therefore, the method for decoding/encoding a video signal uses a variety of inter layer prediction methods according to the macroblock types of macroblocks of the current and base layers, and removes inter layer redundancy, resulting in increased coding efficiency. | 05-12-2011 |
