In this scheme, the video is divided into equal-sized segments depending upon the bandwidth allocated by the video server. If the video length is not known, then this scheme cannot be applied as the number of video segments cannot be determined. In a live video wherein the video size is unknown, especially the ending time of the live broadcast, e.g., cricket match, this scheme cannot be applied. In this paper, we propose a model that helps the Fast Broadcasting scheme to support live video broadcasting. The basic architecture of the system consists of a live system with one video channel that broadcasts the live video and a video server that broadcasts the already broadcast live video to users.展开更多

The basic approach in these schemes is to divide the video into segments and organize them over the channels for proper transmission. Some schemes use segments as a basic unit, whereas the others require segments to be further divided into subsegments. In a scheme, the number of segments/subsegments depends upon the bandwidth allocated to the video by the video server. For constructing segments, the video length should be known. If it is unknown, then the segments cannot be constructed and hence the scheme cannot be applied to provide the video services. This is an important issue especially in live broadcasting applications wherein the ending time of the video is unknown, for example, cricket match. In this paper, we propose a mechanism for the conservative staircase scheme so that it can support live video broadcasting.展开更多
