APPARATUS AND METHODS OF SCALBLE VIDEO CODING FOR REALISTIC BROADCASTING

摘要

PURPOSE: A scalable video coding apparatus for the real-feeling type broadcasting and a method thereof are provided to maintain the mutual compatibility with the exiting video compression technology and are provided to consider the compression of a depth video for producing the middle viewpoint video for the real-feeling type broadcasting, thereby viewing the three-dimensional or stereoscopic video at each viewpoint. CONSTITUTION: A spatial scalable coding unit (560) refers to the predictive coding within the viewpoint and the motion information of a base layer in the base layer of a color video and a depth video, and performs the predictive coding in an enhanced layer. A qualitative scalable coding unit (570) uses a quantization step which is a method for the qualitative scalability of the color video. A motion estimation unit uses the motion information of the base layer of the color video as the predictive data, and encodes the base layer of the depth video.
