Streaming Media Transmission Framework Based on EMIPLIB for Research and Implementation

流媒体网络传输存在丢包率高、吞吐量受误码率影响和传输延时等特殊的QoS问题。该文在系统地分析流媒体的QoS指标的基础上,提出了一种新的基于EMIPLIB(EDM Media over IP Iibray)的流媒体传输的整体框架,此框架较好地体现了开放化、标准化、模块化、可扩展、可重构的设计理念,其优点是适应范围广、移植性好、可扩展性好、实现比较容易,为流媒体应用提供了能够保证QoS的传输平台,并简化了流媒体应用开发的难度,此框架为流媒体传输提供了一种新的方案。

High packet loss ratio, low throughput and long transmission delay are special QoS problems existing in streaming media transmission. This paper proposes a new framework based on the EMIPLIB（EDM Media over IP Library）by thoroughly and systematically analyzing the existing QoS criteria. This framework embodies some classic design philosophies such as open, standardized, modular, scalable and reconfignration. It＇ s widely apphcable, good portable, large scalable and easier to implementation. It provides a platform for the streaming media transmission, which guarantees the QoS and simplifies the complication of developing streaming media application. This framework is a new solution to streaming media technology.
