    Abstract: PURPOSE: A system and a method for providing 3d image data in a 3d image system are provided to convert a depth image into a parallax map to transmit image data by a new transmission method, thereby increasing coding efficiency in transmission and reducing a calculation amount with a memory used in a receiver. CONSTITUTION: The first filtering unit(120) quantizes depth image data using a histogram included in image data received from image photographing devices. The second filtering unit(140) measures discontinuity in the quantized depth image data. The second filtering unit performs smoothing and filtering based on an inclined direction using the discontinuity. An encoding unit(180) encodes reference image data including a generated parallax map and the image data.

    Abstract: An apparatus and a method for rendering a depth based image in mobile broadcasting are provided to apply a discontinuous maintenance filter to a depth image, thereby minimizing distortion of the depth image. A discontinuous maintenance filter(111) smoothes a depth image correspondingly to gradient amplitude of the depth image. An adaptive smoothing filter(115) calculates a gradient degree of the depth image transmitted from the discontinuous maintenance filter. Only when gradient amplitude is larger than a preset value, the adaptive smoothing filter applies a filter feature according to a gradient direction to the depth image. The adaptive smoothing filter transmits the depth image to an encoding module(120). The encoding module transmits a reference image and the depth image.
