    Abstract: The present invention relates to video information prediction and video encoding/decoding using the same. The video encoding, according to the present invention, comprises the steps of: decoding a picture of a reference layer; inducing an inter-layer reference picture by sampling the decoded picture of the reference layer; forming a reference picture list that includes the inter-layer reference picture and a reference picture of a current layer; generating a prediction sample for a current block by predicting the current block of the current layer on the basis of the reference picture list; generating a residual sample for the current block on the basis of the prediction sample; and encoding the residual sample.

    Abstract: The present invention relates to a video encoding/decoding method, and more particularly, to an error resilient loop filtering method, and a signaling method thereof. According to one embodiment of the present invention, provided is a video decoding method including: a step of determining whether a Constrained Intra Prediction (CIP) mode is used; a step of determining decoding parameters of blocks located on both sides of a boundary to be filtered; and a step of deciding whether an in-loop filter is applied to samples located on both sides of the boundary to be filtered, on the basis of the use/non-use of the CIP mode and the decoding parameters of the blocks located on both sides of the boundary to be filtered.

    Abstract: The multi sample prediction method of the present invention comprises the steps of: determining a sample group consisting of a plurality of samples inside a decoding target block; determining a representative position corresponding to the sample group, inside the decoding target block; determining a representative prediction value for the sample group, on the basis of the determined representative position; and determining the determined representative prediction value as the final prediction value for each of the plurality of samples making up the sample group. The present invention enhances efficiency in encoding/decoding and reduces complexity thereof.
