    Abstract: Disclosed are a method and an apparatus for an adaptive HTTP streaming service using metadata of content. The metadata includes a minimum buffer time attribute indicating a minimum amount of initially buffered media content. A terminal receives content from a server before playing the content, and buffers the content by at least the minimum amount. The metadata includes a range attribute designating a range of a target indicated by a URL. The terminal receives bytes designated by the range attribute from the URL, and plays the content using the received bytes.

    Abstract: PURPOSE: An intra prediction mode encoding/decoding method and an apparatus thereof are provided to derive a most probable mode (MPM) from a peripheral prediction unit during the encoding/decoding of an intra prediction mode, and perform alignment operation according to the presence of an MPM having the same prediction mode as the intra prediction mode of a current prediction unit among the derived MPMs, thereby reducing the computational complexity of an image encoder/decoder. CONSTITUTION: If there is an MPM having the same prediction mode as the intra prediction mode of a current prediction unit among MPMs derived from a peripheral prediction unit adjacent to the current prediction unit, an encoder and/or decoder encodes and/or decodes an index indicating which MPM is identical to the intra prediction mode of the current prediction unit (S1010~S1030). If not so, the encoder and/or decoder align the derived MPMs based on the mode value of the MPM. By using a residual intra prediction mode, the intra prediction mode of the current prediction unit is encoded and/or decoded (S1040,S1050).

    Abstract: PURPOSE: A method for encoding and decoding a motion vector by using a motion vector predictor and a device thereof are provided to increase encoding efficiency by efficiently encoding and decoding the motion vector. CONSTITUTION: When an MV(Motion Vector) encoding/decoding device performs MV prediction, the device performs a step(0) for inducing a left MV predictor, a step(1) for inducing an upper-end MV predictor, and a step(2) for inducing a temporal MV predictor. When the three MV predictors are induced, the device checks redundancy of an MV to remove a MV predictor having the same MV from an MV predictor list.
