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 translation: 提供了一种使用内容元数据的自适应超文本传输​​协议（HTTP）流传输服务的方法和装置。 元数据可以包括一个或多个BaseURL元素。 可以基于BaseURL元素生成形成介质的段的统一资源定位符（URL）。 另外，可以通过将BaseURL元素中的BaseURL元素映射到该段的sourceURL属性来生成段的URL。 生成的URL指示的段可能相同。

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: An integrated app store device according to the present invention includes an authentication server performing registration and authentication on a client terminal, a content managing server performing one of registration, search, and download of an application, a web application server providing a web front for a user, and an interworking server providing an open API (Application Programming Interface) for an external app store to access. Accordingly, functions of an app store are defined in the form of a standard-based common interface (Open API) and various terminals and platform environments are supported, thus providing an open-type app store model that may be efficiently expanded even when the type of user terminal and type of service or business environment are varied.
