human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Realistic broadcasting using multi-modal immersive media"):
  Abstract: Realistic broadcasting is considered as a next generation broadcasting system supporting user-friendly interactions. In this paper, we define multi-modal immersive media and introduce technologies for a realistic broadcasting system, which are developed at Realistic Broadcasting Research Center (RBRC) in Korea. In order to generate three-dimensional (3-D) scenes, we acquire immersive media using a depth-based camera or multi-view cameras. After converting the immersive media into broadcasting contents, we send the immersive contents to the clients using high-speed and high-capacity transmission techniques. Finally, we can experience realistic broadcasting represented by the 3-D display, 3-D sound, and haptic interaction. Demonstrations show two types of broadcasting systems: the system using a depth-based camera and the system using multi-view cameras. From the realistic broadcasting system, we can generate new paradigms for the next generation digital broadcasting.
