Timely delivery of video data in staircase scheme

Abstract

The staircase scheme is one of the important broadcasting schemes. It however does not provide the video data to all users on time. This problem has been overcome in the conservative staircase scheme at the cost of bandwidth. The number of segments in the conservative staircase scheme is less and hence the segment size is large, which signifies the user's waiting time. Thus, the conservative staircase scheme has more user's waiting time than the staircase scheme. In this paper, we propose a hybrid scheme of the staircase and conservative staircase schemes that provides the video data to users on time and has better performance than the conservative staircase scheme for the user's waiting time.
