Abstract: Disclosed are a device and a method for providing an adaptive HTTP streaming service using metadata on content. The metadata of the content can be transmitted to a terminal by being efficiently divided to correspond to the purpose of use of the terminal by using general media information or unique media information. A group includes one or more representations of the content. The metadata includes a group element, and the group element provides a summary on the properties of the representations included in the group.

Abstract: Provided is an apparatus and method for transmitting and receiving a streaming service. An inter-arrival jitter may correspond to a delay variation in arrival time between TCP packets arriving at an apparatus for receiving the streaming service. The apparatus for receiving the streaming service may determine a de-jitter buffering time to absorb a network jitter before TS packets in a TCP packet is input to a T-STD buffer model. Based on the de-jitter buffering time, an initial playout delay lime at the apparatus for receiving the streaming service may be determined.

Abstract: PURPOSE: An apparatus for providing streaming contents and a method thereof are provided to efficiently divide media information in active HTTP streaming by using general media information and specific media information. CONSTITUTION: A terminal(110) receives meta data of a media or the meta data about a specific cycle of the media from a server(100)(610). The terminal processes the meta data about the specific cycle(620). The terminal extracts information provided through the meta data. The terminal requests a server of segments(630). The server extracts a data part suitable for the requested segments if there is a need to parse a media(640). The server transmits the segments suitable for each request from the terminal to the terminal(650). The terminal plays the media by decoding and rendering data in the media included within the segments(660).

Abstract: PURPOSE: A device for providing streaming content and a method thereof are provided to efficiently divide and transmit MPD(Media Presentation Description) in active http streaming by using general MPD and specific MPD, thereby efficiently transmitting the MPD by the usage purpose of a terminal. CONSTITUTION: A terminal(110) receives meta data of a media with one or more cycles from a server(100). The terminal approaches to segments of the media based on the information which the meta data provides. The terminal performs decoding and rendering of the media data of the segments. Each cycle includes one or more groups. Each group includes one or more representations of the media.
