Effective Utilization of Disk Bandwidth for Supporting Interactive Video-on-Demand
نویسندگان
چکیده
This paper proposes a novel data retrieval scheme that achieves effective utilization of disk bandwidth for designing fully interactive video-on-demand systems. The main distinctions of the proposed data retrieval scheme are (1) it requires no extra disk bandwidth to support interactive features such as fast forward search and fast backward search; and (2) it is based on a data placement scheme that can effectively utilize disk bandwidth during normal-speed playback.

متن کاملA Disk Data Placement and Retrieval Scheme for Supporting Interactive Video-on-Demand
This paper proposes a novel data placement and retrieval scheme based on a general two-level disk array architecture for designing interactive video-on-demand systems. The proposed scheme is of significance because the two-level disk array architecture exploits both parallelism and concurrency offered by fine-grain and coarsegrain disk array structures. Moreover, the execution of an interactive...

متن کاملPerformance Measurement of Bandwidth Utilization for Video-on-Demand Streaming Across Networks
During the last two decades, it has been observed the exponential growth in the number of users coupled with variety of wide area networks (WAN) at the global levels and provisions for bulky video data download through them. To achieve the goal of supporting such hundreds of interactive data streams simultaneously, optimization and various tradeoffs need be applied for the storage of data on hu...
متن کاملA Multimedia Storage System for On-Demand Playback
This paper presents the design of a multimedia storage system for on-demand playback. The design stresses effective utilization of disk bandwidth with minimal data buffer to minimize overall system costs. The design procedure is most distinctive in the following two aspects: 1. It bases on a tight upper bound of the lumped disk seek time for the Scan disk scheduling algorithm to achieve effecti...
