Patent number: 8836702Abstract: A ray tracing core comprises a ray tracing unit (RTU), a control unit, and a tree build unit (TBU). The ray tracing unit performs ray tracing based on a spatial partitioning structure. The control unit calculates the degree of complexity of the spatial partitioning structure by monitoring the load state of the ray tracing unit. The tree build unit builds the spatial partitioning structure having the degree of complexity which is calculated. The load state is determined based on a frame rate which is processed in the pertinent unit. The spatial partitioning structure applies a K-dimensional tree. For example, the degree of complexity can be modified according to either the maximum primitive number of a leaf node with respect to a K-dimensional tree structure or a tree depth.Type: GrantFiled: February 18, 2011Date of Patent: September 16, 2014Assignees: Siliconarts Inc., Industry-Academia Cooperation Group of Sejong UniversityInventors: Hyung Min Yoon, Woo Chan Park

Publication number: 20140184741Abstract: The present invention is related to a method for moving the position of a base view from an arbitrary GOP (Group Of Pictures) start position to implement an efficient encoding structure in multi-view video encoding. The existing multi-view video encoding method exhibits low encoding efficiency when correlation between the base view and a dependent view is low, since the base view is assumed to be fixed. Moreover, in case the view in a live broadcasting program desired by a producer changes from the base view to another, the user has to consume more bit streams and decoder complexity than those consumed when decoding is performed with respect to the base view. Therefore, to alleviate the drawbacks of the existing multi-view video encoding method, the present invention provides a method for designing syntax elements by which the base view can be moved, thereby supporting an efficient encoding structure.Type: ApplicationFiled: December 27, 2013Publication date: July 3, 2014Applicants: Industry-Academic Cooperation Group of Sejong University, Electronics and Telecommunications Research InstituteInventors: Jung Won KANG, Ha Hyun LEE, Jin Ho LEE, Jin Soo CHOI, Jin Woong KIM, Jong Ki HAN, Jae Yung LEE
