An apparatus and method for processing video data using gaze detection are provided. According to the apparatus and method, the position of an area-of-interest which a user gazes at in a current image being displayed is detected and the area-of-interest is scalably decoded to enhance the picture quality such that the work load to the decoder can be reduced and the bandwidth limit of a data communication channel can be overcome.

Scalable multi-view image encoding and decoding methods and apparatuses are provided. The scalable multi-view image encoding and decoding methods and apparatuses filter multi-view images input from a plurality of cameras in spatial- axis and in temporal-axis directions using motion compensated temporal filtering (MCTF) or hierarchical B-pictures and scalably code the filtered multi-view.

Disclosed is a method and apparatus for illumination compensation in a multi view video coding. The method includes deriving a predicted illumination compensation value of the current block by using information on neighbor blocks of the current block when a current block performing illumination compensation is in a skip mode; setting the current block not to perform the illumination compensation when the derived predicted illumination compensation value is 0 and setting the current block to perform the illumination compensation when the derived predicted illumination compensation value is not 0.

A method of and apparatus for setting a virtual image region is provided in order to efficiently perform motion estimation and compensation of a panorama image including 360-degree omni-direction image information. The method includes the steps of searching a previous panorama image for reference data corresponding to all or part of a virtual image region of a current patch desired to be motion-estimated in order to determine the presence of the reference data, and selectively mapping the reference data to all or part of the virtual image region. By doing so, the panorama image containing omni-directional image information is coded by using a 2-dimensional moving picture coding method without change, while the coding efficiency in the process of motion estimation and compensation can be greatly improved.

A method of and apparatus for efficient encoding and decoding by reconstructing an icosahedron panorama image are provided. The method includes: dividing patches forming a top part and a bottom part, respectively, in development figure of an icosahedron panorama image, from patches forming a middle part; reconstructing the divided patches on a 2-dimensional plane so that patches having a high correlation are placed adjacent to each other; and encoding the re¬ constructed patches.

Provided are method and apparatus for transmitting and receiving a multimedia streaming service via a network. The method of providing a multimedia streaming service includes: dividing encoded data of a video including at least one of a 2D video and a 3D video into fragments; determining at least one of 3D signaling information for each fragment and relationship information to be used when the video refers to other videos; and continuously transmitting the fragments including the property information regarding the fragments and encoded video data.
摘要:
A method for sending media information by a first terminal in a multimedia communication system is provided. The method includes generating scene configuration information that includes information regarding at least one medium of multiple media, and sending the scene configuration information to a second terminal, wherein the information regarding the at least one medium includes at least one of information indicating whether to allow reproduction of the at least one medium in the second terminal, resource information used to reproduce the at least one medium, position information used to reproduce the at least one medium on a screen, and reproduction time information for the at least one medium.
