摘要
为了提升播存环境中广播传输效率,满足个性化推荐和补包机制的需求,提出了一种应用于播存环境中基于广播的新型文件传输机制。介绍了播存环境对于当前互联网的价值,在此基础上分析了播存环境对基于广播的文件传输机制的基本要求。提出一种将需要发送的视频、音频、文本文件等直接封装成含有控制信息和文件分类信息的TS流方案,设计了相应封装格式。在播存环境原型系统中的实验结果表明,该机制传输成本较低、传输效果较好。
To promote transmission efficiency and satisfy the need of personalization recommendation and packet loss recovery,a broadcast-based method for delivering files in broadcast-storage environment was proposed.Firstly,the broadcast-storage envi-ronment was introduced and it was pointed out that there were several basic requirements that a broadcast-based method for de-livering files should meet.Then,based on these requirements,a method encapsulating data directly and taking the personaliza-tion recommendation into consideration by adding categorization information was proposed.Finally,performances and efficiency of the proposed method were demonstrated in the broadcast-storage prototype.
