The past decade has witnessed a proliferation of personal computers at homes, businesses, classrooms, libraries, etc. Most often, these systems are used to disseminate information. Recently, multimedia repositories have added to the excitement of this information age by allowing a user to retrieve and manipulate continuous media data types (audio and video objects). The design and implementation of these systems is challenging due to both the large size of objects that constitute this media type and their continuous bandwidth requirement. Compression in combination with the availability of fast CPUs (for real-time decompression) provide effective support for a continuous display of those objects with high bandwidth requirement. Hierarchical storage structures (consisting of RAM, disk and tertiary storage devices) provide a cost-effective solution for the large size of their repositories. The focus of this study is on personal computers (single user, single display) that employ fast CPUs, compression and hierarchical storage structures to support multimedia applications. Its goals are to ensure a continuous display of audio and video objects while minimizing the latency time observed by the user. Its contributions include a novel pipelining mechanism and PIRATE as a technique to manage the disk resident objects.
在过去的十年中,家庭,企业,教室,图书馆等中的个人计算机激增。这些系统通常用于传播信息。最近,多媒体存储库通过允许用户检索和操纵连续的媒体数据类型(音频和视频对象)而增加了这种信息时代的乐趣。由于构成此媒体类型的对象的大小很大,以及它们对带宽的连续要求,因此这些系统的设计和实现具有挑战性。压缩与快速CPU的可用性(用于实时解压缩)相结合,为连续显示具有高带宽需求的那些对象提供了有效的支持。分层存储结构(由RAM,磁盘和第三存储设备组成)为大型存储库提供了一种经济高效的解决方案。这项研究的重点是采用快速CPU,压缩和分层存储结构来支持多媒体应用程序的个人计算机(单用户,单显示器)。其目标是确保连续显示音频和视频对象,同时最大程度地减少用户观察到的等待时间。它的贡献包括新颖的流水线机制和PIRATE作为管理磁盘驻留对象的技术。 P>
