摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present invention relates to an apparatus and a method of stitching a real-time image. More specifically, stitching-related information is generated, a parallax occurrence region in an overlap region is tracked, and correction for reducing parallax occurring in the parallax occurrence region and correction of an image distortion occurring in a non-overlap region are performed for output.

摘要： Disclosed is an apparatus and method of generating a stitched image. A method of generating a stitched image according to the present disclosure includes: obtaining a plurality of input images; determining whether or not a parallax problem occurs between overlapping areas of the obtained input images; updating a predetermined look-up table according to the determination; and generating a stitched image by applying the updated look-up table to the input images.

摘要： The present invention relates to a method and an apparatus for inter-layer intra prediction. The method for inter-layer intra prediction comprises: a step of determining a reference layer for inter-layer intra prediction; a step of generating intra prediction information from the reference layer; and a step of performing inter-layer prediction on the current block based on the intra prediction information. In cases where the same location block of the reference block corresponding to the prediction object frame on a temporal axis is inter predicted in the reference layer, intra prediction information is generated based on the intra predicted same location block from among the previous and post frames of the reference frame.
