    摘要: A method for performing inter-layer prediction when encoding/decoding a video signal, includes confirming, by a decoding apparatus, whether or not only one macroblock of a field macroblock pair of a base layer is coded in intra mode, the field macroblock pair is two vertically adjacent field macroblocks. The method further includes predicting motion information of a current macroblock pair in an enhanced layer using motion information of an inter-mode macroblock in the field macroblock pair if the confirming confirms that only one of the macroblocks in the field macroblock pair is coded in the intra mode. A frame macroblock pair is constructed from the field macroblock pair if at least one of the macroblocks the field macroblock pair is coded in the intra mode, and texture prediction information of the current macroblock pair is obtained using texture information of the constructed frame macroblock pair.

    摘要: 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.

    摘要: Embodiments provide a method and apparatus for decoding/encoding a video signal using inter-layer prediction. The method includes obtaining inter-layer prediction identification information and quality identification information. The method further includes obtaining prediction constraint information based on the inter-layer prediction identification information and the quality identification information. The prediction constraint information indicates whether it is constrained to use an intra-base prediction mode in predicting a current block when a corresponding block covers at least two slices of a base layer. The method further includes decoding a current block by using the intra-base prediction mode when the prediction constraint information indicates it is not constrained to use the intra-base prediction mode in predicting the current block in case that the corresponding block covers at least two slices of the base layer.
