| Research Abstract |
With the spread of high-definition video devices, and with the advance of digital broadcasting systems and video portal services in the Internet domains, numerous high-definition video presentations have become available in everyday life. These circumstances strengthen the desire of people to enjoy those video contents in new ways. This paper presents a proposal of a new multivision video provisioning system that enables numerous users to access, interactively, any view area with any desired resolution. The basis is that the partial area (tile)-based pre-coded video streams are stored in advance. These multiple streams are joined dynamically and delivered based on the user's view-area position. This paper details a H.264/AVC tile-based video coding and a fast tile stream joiner scheme. Simulation experiments and our practical implementation demonstrate the feasibility and effectiveness of our proposal.
