基于E语言的数字电视DVB-H系统数据链路层功能验证研究

随着数字电视的迅速发展和移动多媒体设备——手机,PDA等的普及,新的技术被发展并应用于手持设备数字电视的接收,DVB-H手机电视标准提供了很好的手机电视接收解决方案。该标准是DVB-T的扩展应用,在数据链路层实现了时间分片、多协议封装和前向纠错功能,从而降低了平均功耗,增强了移动接收的鲁棒性。提出了基于E语言的DVB-H系统数据链路层的功能验证环境,并给出了具体验证步骤和结果分析,最后通过验证分析完善和改进了DVB-H数据链路层系统功能,此外对基于E语言的验证方法进行了一定的研究。

Function Verification Research Based on E Language for DVB-H Link Layer

With the rapid development of digital television and mobile equipment,new technology has been proposed to receive broadcasting television program on the handheld devices,such as PDA and mobile phone.DVB-H standard which is an extended implement of DVB-T(Terrestrial Digital Video Broadcasting)that adds time-slicing and MPE-FEC(forward error correction for multi-protocol encapsulated data) in the link layer.As a preferable approach,it provides robust reception and effectively reduces the average power consumption.This paper focuses on building verification environment for DVB-H link layer based on E language,and offers detail steps and resulting report.As a result,the entire system function has been improved and enhanced through exhaustive verification.Furthermore,this paper also does some research on the function verification based on E language.
