    Abstract: Disclosed are an apparatus and a method for providing an adaptive HTTP streaming service using metadata for contents. The metadata includes minimum buffering time property indicating the minimum amount of media contents which are initially buffered. A terminal receives contents from a server before playing the contents and buffers the contents by at least the minimum amount. The metadata includes range properties indicating a target range to which a URL points. A terminal receives bytes from the URL which the range properties indicate, and plays the contents using the received bytes.

    Abstract: PURPOSE: A method for encoding and decoding in an intra prediction mode is provided to simply induce an intra prediction mode without a complicated operation process. CONSTITUTION: If two identical induced most probable modes (MPMs) induced in adjacent prediction units are not included in at least two set prediction modes, an image encoding device sets up remaining two MPMs of an MPM list consisting of three MPMs for a current prediction unit out of the set prediction mode and a proximity prediction mode adjacent to the induced MPMs (S1001,S1003). The image encoding device encodes a prediction mode for the current prediction unit based on the induced MPMs and the set remaining two MPMs. [Reference numerals] (AA) MPM list organization; (S1001) Left MPM=Previously-defined encoding mode A or Left MPM=Previously-defined encoding mode B; (S1002) MPM[0]=Previously-defined encoding mode A, MPM[1]=Previously-defined encoding mode B, MPM[2]=Previously-defined encoding mode C; (S1003) MPM[0]=Left MPM, MPM[1]=Previously-defined encoding mode A, MPM[2]=Previously-defined encoding mode B

    Abstract: PURPOSE: A method for inducing a prediction MV(Motion Vector) and a device using the method are provided to reduce complexity generated when inducing the prediction MV by calculating a final prediction MV by forming a candidate prediction MV list. CONSTITUTION: An image encoding/decoding device induces temporal candidate prediction MV information based on spatial candidate prediction MV information(S1420). The device adds an induced candidate prediction MV to a candidate prediction MV list(S1430). The device removes the same candidate prediction MV to reform the candidate prediction MV list(S1440). The device determines a final prediction MV from the candidate prediction MV list(S1460).
