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.

Method and device for providing streaming content

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. Each of the periods may include one or more representations. The metadata may include information used to describe a relationship between the representations, and include information for terminals having different display bit depth.

Apparatus and method for providing streaming content using representations

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.

Apparatus and method for providing streaming content

Apparatus and method for providing streaming contents

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.

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.
