Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata of the content may be efficiently divided for a purpose of use of a terminal based on general media information or specific media information, and may be transmitted to the terminal. A group may include one or more representations of content. The metadata may include a group element, and the group element may provide a summary of attributes of one or more representations included in the group.

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: 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: An MMT apparatus and an MMT method for processing stereoscopic video data are disclosed. An MMT apparatus, according to an embodiment, comprises: an asset file generation unit for generating a single asset file including all or a part of stereoscopic video data; and a signaling message generation unit for generating a signaling message for delivery or consumption of the stereoscopic video data. In addition, at least one from among the generated single asset file and the generated signaling message includes stereoscopic video information related to the stereoscopic video data.

Abstract: A method for transmitting an MMT packet in an MMT (MPEG Media Transport) system includes: generating an MMT asset by performing encapsulation based on a Media Processing Unit (MPU) generated based on a media Access Unit (AU); generating MMT Composition Information on the MMT asset; generating an MMT packet by packetizing the MMT asset and the MMT-CI; and transmitting the generated MMT packet to a receiving side, wherein the MMT-CI may contain dependency information of the MMT asset on at least one other MMT asset. Accordingly, it is possible to indicate whether an MMT packet depends on other MMT assets when transmitting and receiving multi-layered media data, and to support proper decoding of the MMT asset when providing hybrid delivery-based MMT service.
