Abstract: The present invention is related to a method for moving the position of a base view from an arbitrary GOP (Group Of Pictures) start position to implement an efficient encoding structure in multi-view video encoding. The existing multi-view video encoding method exhibits low encoding efficiency when correlation between the base view and a dependent view is low, since the base view is assumed to be fixed. Moreover, in case the view in a live broadcasting program desired by a producer changes from the base view to another, the user has to consume more bit streams and decoder complexity than those consumed when decoding is performed with respect to the base view. Therefore, to alleviate the drawbacks of the existing multi-view video encoding method, the present invention provides a method for designing syntax elements by which the base view can be moved, thereby supporting an efficient encoding structure.

Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.
