    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 streaming service method for providing scalability and view information and a device thereof are provided to insert scalability information to an extended TS header, thereby providing the scalability information at a TS level. CONSTITUTION: A packet generating unit(610) generates an MPEG-2 transport stream packet. A transmission unit(620) transmits an MPEG-2 transport stream using the MPEG-2 transport stream packet. The MPEG-2 transport stream includes a scalable video stream. The header of the scalable video stream packet includes scalability information of the scalability video stream.

    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.
