    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).

    Abstract: The present invention provides methods for providing a media content performed by a client and by a server, a client for providing a media content, and a server for providing a media content. The method comprises: transmitting a request for the media content to a server based on a Media Presentation Description (MPD) of the media content; and receiving a segment of the media content based on the MPD, from the server. The MPD includes one or more periods, the period includes one or more adaptation sets, the adaptation set includes one or more representations, the representation includes one or more segments, the period is defined based on a period element including a start attribute and a duration attribute, and each of the representations starts from a start time of the period and continues to an ending point of the period. The start time of the period is determined one of below methods: i) when a start attribute exists in a first period element of the first period, a start time of the first period is equal to the start attribute, ii) when a start attribute does not exist in the first period element of the first period, and when a second period element of the second period includes a duration attribute, the start time of the first period is determined by adding the duration attribute of the second period element to a start time of the second period, and iii) when a start attribute does not exist in the first period element of the first period, and when the first period is the first of the one or more periods, the start time of the first period is set to 0. The second period is previous period with respect to the first period.

    Abstract: The present invention relates to a video summary description scheme for describing video summary by meta data. The video summary provides overview functionality, which makes feasible to understand overall contents of the original video within short time and navigation and browsing functionalities, which make feasible to search the desired video contents efficiently. According to the present invention the HierarchicalSummary Description Scheme (DS) comprises at least on HighlightLevel DS and selectively comprises the SummaryThemeList DS. The HightlightLevel DS describe highlight level an may have zero or at least one lower HighlightLevel DS. The HighlightLevel DS comprises one or more HighlightSegment DS which is describing highlight segment information constituting the video summary of the highlight level. The HighlightSegment DS comprises the VideoSegmentLocator DS for describing the time information of corresponding segment interval. Also, the HighlightSegment DS may comprise the ImageLocator DS for describing the representative image information of corresponding segment, the SoundLocator DS for describing the representative sound information, and the AudioSegmentLocator DS for describing the audio segment information constituting the audio summary.
