Abstract: A device for providing a realistic media content, includes: inward facing image acquisition unit configured to acquire multiple inward facing images that are taken by an inward method using multiple cameras arranged around an object; an outward facing image acquisition unit configured to acquire multiple outward facing images that are taken by an outward method using the multiple cameras arranged around a point; a background image generation unit configured to generate a 360° cylindrical image by stitching the multiple outward facing images and then convert the 360° cylindrical image into a 360° spherical image to generate a background image; a 3D object reconstruction unit configured to extract a region of the object from the multiple inward facing images to generate a 3D object; and a combined image transmission unit configured to combine the background image with the 3D object and transmit the combined image to a display device.

Abstract: Disclosed are a communication method and communication apparatus using an ambient backscatter communication. A transmission apparatus may include generating a plurality of bitsets by fragmenting data based on a predetermined bitset length, mapping the plurality of bitsets to a plurality of switching patterns based on a data size, and controlling a reflection of a background radio frequency (RF) signal based on a corresponding mapped switching pattern, a total number of the plurality of switching patterns may be determined based on the bitset length, and each of the plurality of switching patterns may have a different length.

Abstract: Disclosed are an apparatus and a method for broadcasting a stereoscopic 3D video. According to an exemplary embodiment of the present invention, since the LLR operation of each of the HP bitstream and the LP bitstream is provided by the four fundamental arithmetic operations through the logarization for the probability that a video bit for the reception symbol vector is to be transmitted, the operation complexity of the HP bitstream LLR and the LP bitstream LLR is lowered. A high-quality stereoscopic video can be displayed and the left video bitstream is updated by providing the prior bitstream of the left video to the first SISO decoder, thereby improving reliability of the decoding for the left video.
