Segmentation Analysis for Effective Usage of Network Resources in Video Streaming

As multimedia transmission requires a high network bandwidth and rigorous response time, the design of good network transmission system with high utilization of network resources is the key need. This paper investigates methods to obtain better transmission schedules and summarization schemes for browsing streaming video. It also aims to develop a generalized strategy for evaluating the performance of these schemes irrespective of the streaming file format used. An algorithm has been developed to estimate a minimum value of the initial delay required for providing jitter-free playback of a video segment at the given transmission rate. The video transmission techniques presented in research publications try to reduce the bandwidth required for transmitting video and they also focus on reducing the buffer requirement but the video summarization techniques proposed in these research papers do not consider the problems faced by streaming video while browsing through the Internet. In this paper a dynamic rate-changing algorithm and a variable-initial-delay algorithm are proposed for dividing the video into segments. These segments are used in a hierarchical video summarization scheme for effective streaming and browsing and the resource requirements for transmitting these video segments can be estimated by the methods proposed in this paper.
