We present the design and implementation of an 8-view three-dimensional (3-D) video player system based on a multi-core processor environment, which operates faster than existing video player systems. We propose a structure for obtaining near-optimum speed by parallelizing the component modules to process large volumes of 8-view image data at a high speed. In order to exploit task parallelism in the video player, we have designed a multiple-video decoder, a view synthesizer that creates the 3-D image from the multi-view image data, and a 3-D renderer for an 8-view display in a pipeline structure. For load balancing and exploiting data parallelism in the modules, the decoder is divided into units of viewpoint, and the view synthesizer is geometrically divided based on the synthesized images. As a result of this experiment, 8-view images are correctly synthesized, and the sense of three dimensions can be observed when watching the images on the 8-view auto-stereoscopic display. The proposed structure could be used to process large volumes of multi-view image data at high speeds by utilizing the maximum capacity of the multi-core processors.
