Abstract: PURPOSE: A method for providing streaming content and a device thereof are provided to use segments in each period when playing a media consisted of a series of one or more periods. CONSTITUTION: A terminal(100) receives meta data of a media with one or more periods. The terminal approaches to segments of the media. The terminal decodes and renders data in the segments of the media. Each period includes one or more representations of the media. Each representation starts from an initial point of the period. Each representation continues to the end point of the period. Each representation continues to an end point of the period.

Abstract: PURPOSE: A video streaming playback apparatus and method thereof are provided to support a playback mode which is composed of a trick mode and a random access mode by using key frame information within a segment. CONSTITUTION: An information description unit(110) describes information for a key frame of an image group which constitutes a segment. A reproduction unit(120) reproduces a key frame in a playback mode selected from a random access mode, a fast forward mode, and a fast backward mode based on the described key frame information. A video summary unit(130) transmits the key frame to a client. The client reproduces the key frame.

Abstract: PURPOSE: A device for providing streaming content and a method thereof are provided to assign the minimum amount of buffered media in the beginning when playing the content. CONSTITUTION: A client receives meta data for content or for a specific interval of the content from a server(120). The client processes the meta data for the specific interval(130). The meta data includes the minimum buffer time property which shows the minimum amount of buffered media content at the beginning for playing the media content. The client requests fragments to the server(140). The server performs parsing of the content(145). The server transmits the fragments suitable for each client request to the client(150).

Abstract: PURPOSE: A pixel domain distributed video codec apparatus and an encoder and a decoder using the same are provided to offer a superior image quality based on the correlation and statistical redundancy by assigning an analysis code. CONSTITUTION: In a pixel domain distributed video codec apparatus, an encoder and a decoder assign analysis code using the correlation and statistical redundancy about the concentration of a difference between a WZ(Wyner-Ziv) frame and an SI(Side Information). A gray encoder(104) assigns the analysis code.
