Virtual Space Broadcasting based on the Speed of Avatar Movement

Large-scale virtual space, Broadcast, Scheduling strategy


We herein propose a broadcast method of virtual space to provide users with a large volume of data. In the proposed system, a server divides virtual space into multiple sub spaces and repeatedly broadcasts spatial data of the sub spaces to clients using a broadband channel. We investigate two scheduling strategies of the broadcast program in order to reduce the average waiting time for the avatar of a user to migrate to an adjacent subspace considering the broad cast bandwidth between a server and clients and movement speed of the user in virtual space.
