Disclosed herein is a non real-time broadcast receiving system. The system includes: a non real-time service decoder dividing received non real-time service content into a transmission block according to a protocol; a service content manager monitoring whether the receive of the non real-time service content stops and acknowledging a schedule regarding whether a portion with errors in the non real-time service content is retransmitted; a memory storing a portion without errors in the non real-time service content; a file checker checking whether errors are produced during the receive of the non real-time service contents and determining whether the portion with errors in the non real-time service content is retransmitted; a retransmission request signal generator generating a retransmission request signal; a return channel transmitter transmitting the retransmission request signal; and a return channel receiver receiving data corresponding the portion with error.

A non-real time stereoscopic video service method and apparatus are provided. The non-real time stereoscopic video service method performed by a reception apparatus, including: extracting a program association table (PAT) from a received transport stream (TS) and analyzing the same; extracting a program map table (PMT) corresponding to a program selected by a user from the PAT and analyzing the same; extracting a stereoscopic video service descriptor from the PMT and analyzing the same; generating frame and/or time information of an image to be reproduced according to the analysis of the stereoscopic video service descriptor; and reproducing an image by synchronizing a reference image and a supplementary image based on the generated frame and/or time information.

Provided is a method and apparatus for encoding and decoding multi-view video data. The encoding method includes: decomposing each view image of the multi-view video into an overlapped region and a non-overlapped region, the overlapped region being overlapped with other view image and the non-overlapped region not being overlapped with other view image; generating a stitched image by combining the non-overlapped region of each view image and a middle view image; encoding the stitched image using a first encoding algorithm; and encoding the overlapped region of each view image, using a second encoding algorithm. Further, the decomposing step includes the steps of estimating disparity information for each view image, based on a predetermined view image; and decomposing each view image into said overlapped region and said non-overlapped region using the estimated disparity information.

Provided is a method of editing a depth image, comprising: receiving a selection on a depth image frame to be edited and a color image corresponding to the depth image frame; receiving a selection on an interest object in the color image; extracting boundary information of the interest object; and correcting a depth value of the depth image frame using the boundary information of the interest object.
摘要:
A multi-view video coding (MVC) system, a decoding system, and a bitstream extraction system are provided for decoding a base view and supporting a view random access. The MVC system includes: a coding unit that codes the video signal to a base view and a multi-view; and a base view identifier adding unit that adds a base view identifier of the base view to a parameter set.

A method for providing social broadcasting services by a broadcasting station is registered. The method for providing social broadcasting services includes receiving from a social network server like function related information triggering transmission of an interest indicator indicating that a user of a user equipment has an interest in broadcasting programs provided by a content provider; and transmitting both of the broadcasting programs and additional data including the like function related information to the user equipment. By the configuration, the exemplary embodiments of the present invention can share the personal's opinion and thoughts and the additional data associated with the corresponding programs through the social circle while the user viewing the broadcasting programs in real time during the movement.

A method and a device for adjusting depth perception, a terminal including a function for adjusting depth perception and a method for operating the terminal are provided. The method for adjusting depth perception includes: obtaining color and depth videos of a user; detecting a user's position based on the obtained depth video of the user; calculating a range of maximum and minimum depths in a 3-dimensional (3D) video according to the detected user's position; and adjusting a left and right stereo video generating interval of the 3D video to be rendered so as to satisfy the calculated range of the maximum and minimum depths. Therefore, during a 3D or multi-view video call, the 3D video having a three-dimensional effect optimized according to the user's position may be provided.
