Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include a minBufferTime attribute indicating a minimum amount of initially buffered media content. A terminal may receive content from a server before playback of the content, and may buffer the content by at least the minimum amount. The metadata may include a range attribute that designates a range of a target indicated by a Uniform Resource Locator (URL). The terminal may receive bytes designated by the range attribute from the URL, and may play back the content using the received bytes.

Abstract: The present invention relates to a method and an apparatus for interlayer intra-prediction, and the method for interlayer intra-prediction, according to the present invention, comprises the steps of: deciding whether to apply an interlayer prediction to an enhancement layer; and performing a prediction on a current block of the enhancement layer based on reference information that is generalized and generated from a reference picture, which is decoded, of a reference layer, when the interlayer prediction is applied.

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.

Abstract: A coding method of reducing interlayer redundancy using mition data of FGS(fine grain scalability) layer and device thereof are provided to extract a bitstream having changed scalability from a bitstream generated by using an FGS layer for interlayer motion prediction. A lower spatial layer of an original image is transformed and quantized(S1410). The motion of an upper spatial layer of the original image is predicted by using motion data of an FGS layer in the transformed and quantized lower spatial layer. The transformed and quantized lower spatial layer and the upper spatial layer are encoded. The motion data of the FGS layer is recovered(S1420). Interlayer motion prediction is performed by removing motion data of the upper spatial layer overlapping with the motion data of the recovered FGS layer(S1450).
