Abstract: The present invention relates to image encoding and decoding of a structure including at least one layer, quality, space, and view and, more particularly, to a method for predicting an upper layer signal using one or more reference layers when encoding and decoding the upper layer. The method can generate a reference picture list including a decoding image of a reference layer comprising lower layers, when generating a reference image list used in predicting motions of the encoding and decoding image of the upper layer and in compensating for the motions. Therefore, the method can improve encoding efficiency by adjusting the position of the decoding image of the reference layers and the order of decoding images of the reference layers in the reference picture list, when generating the reference picture list including the decoding image of the reference layers.

Abstract: Disclosed are a method and an apparatus for encoding/decoding a video, capable of supporting a plurality of layers. The method of decoding the video comprises the steps of: performing a scanning operation by selecting a scanning mode for a decoding target block at an upper layer; performing an inter-layer prediction operation for the decoding target block using information of a corresponding block at a lower layer corresponding to the decoding target block; and creating restore sample values using prediction sample values of the decoding target block created through the inter-layer prediction operation and residual values of the decoding target block.

Abstract: Disclosed are a device and a method for providing an adaptive HTTP streaming service using metadata on content. The metadata of the content can be transmitted to a terminal by being efficiently divided to correspond to the purpose of use of the terminal by using general media information or unique media information. A group includes one or more representations of the content. The metadata includes a group element, and the group element provides a summary on the properties of the representations included in the group.

Abstract: PURPOSE: A scalability information expressing method in scalable video coding is provided to express scalability information of various kinds of bit streams. CONSTITUTION: A picture containing an uppermost temporal layer is discarded to reduce the complexity, bit rate, and delay of a bit stream. All the specific temporal layers are discarded. The picture is discarded according to a priority value. A 3-bit temporal_id can express up to eight temporal layers. One or more bits for other elements are combined with the 3-bit temporal_id in order to express more temporal layers.
