In this paper, we propose a fast depth image based rendering method to generate a virtual view image in real-time using a graphic processor unit (GPU) for a 3D broadcasting system. Simple and efficient hole filling method is performed to reduce complexity and prevent hole filling error. Also, we designed a vertical parallel structure for a forward mapping process to take advantage of the single instruction multiple threads structure of GPU. Additionally, we utilize high speed GPU memories to boost computation speed. As a result, we can generate virtual view images 15 times faster than a CPU-based processing.
