Abstract: Disclosed are a method for inducing a prediction motion vector and an apparatus using the same. An image decoding method can include: a step of determining the information related to a plurality of spatial candidate prediction motion vectors from peripheral predicted blocks of a predicted target block; and a step of determining the information related to temporal candidate prediction motion vectors on the basis of the information related to the plurality of spatial candidate prediction motion vectors. Accordingly, the present invention can reduce complexity and can enhance coding efficiency when inducing the optimum prediction motion vector.

Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. The metadata may include a start time attribute and/or a duration attribute of each of the periods. The metadata may determine a start time of each of the periods, and a start time of each of segments included in each of the periods. A terminal may access segments included in each of the periods, may decode and render data of media content included in the segments, and may play back the media content.

Abstract: An intra prediction mode encoding and decoding method, an image decoding device, and an image encoding device operate by deriving most probable modes (MPMs) from surrounding prediction units adjacent to a current prediction unit and deriving an intra prediction mode of the current prediction unit on the basis of an MPM flag indicating whether an MPM having the same prediction mode as the intra prediction mode of the current prediction unit exists among the derived MPMs.

Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.
