Abstract: Disclosed are a 4D printing method using thermal anisotropy and thermal transformation, and the resulting product. The method includes (a) artificially planning transverse printing paths and longitudinal printing paths on a specimen to impose a thermal anisotropy to the specimen, (b) sequentially and alternately forming transversely printed layers and longitudinally printed layers on the specimen by printing a thermoplastic polymer in transverse and longitudinal directions to build a 3D printed product, (c) heating the 3D printed product so that the 3D printed product thermally transforms in a specific direction, and (d) controlling heating time to obtain a 4D printed product having a desired final shape which is formed through the transformation of the 3D printed product over the heating time.

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.
