存在许多不同的方法来通过Web将多媒体内容传递给最终用户。在经典的客户端服务器架构中,存在三种主要的媒体传递方法:HTTP下载、实时流和HTTP流。后者结合了HTTP下载和传统流方法的优点。在本文中,我们提供了一个概述和分析现有的两种技术,这是基于HTTP流:平滑流和HTTP直播流。此外,我们提出了一种增强HTTP流,称为基于BSD的HTTP流。这种增强的媒体交付技术在普通的HTTP Web服务器上工作,利用现有的元数据规范,并且不对所使用的媒体格式和在服务器上组织媒体资源的方式施加任何限制。
A number of different approaches exist to deliver multimedia content to the end-user through the Web. Within classic clientserver architectures, three main media delivery methods exist: HTTP download, real-time streaming, and HTTP streaming. The latter combines the advantages of both the HTTP download and the traditional streaming approach. In this paper, we provide an overview and analysis of two existing technologies which are based on HTTP streaming: Smooth Streaming and HTTP Live Streaming. Further, we propose an enhancement for HTTP Streaming, called BSD-based HTTP streaming. This enhanced media delivery technique works on an ordinary HTTP Web server, makes use of existing metadata specifications, and does not apply any restriction regarding the media formats used and the way media resources are organized on the server.
