Abstract: An MPEG media transport (MMT) apparatus and method for processing stereoscopic video data are provided. The MMT apparatus includes an asset file generator configured to generate a single asset file that contains an entire or part of the stereoscopic video data; and a signaling message generator configured to generate a signaling message for delivery or consumption of the stereoscopic video data. At least one of the generated single asset file and the generated signaling message contains stereoscopic video information related to the stereoscopic video data.

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 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.

Abstract: A method and apparatus for a streaming service to provide scalability and view information are provided. When a scalable video or multi-view video is transmitted using a Moving Picture Experts Group-2 (MPEG-2) system, scalability information or view information regarding the scalable video or multi-view video in a payload may be used. Using the scalability information or view information, a packetized scalable video or multi-view video may be efficiently adapted to various terminal performances, various network characteristics, a specific user preference, and the like.
