KeyTechnologyofDVBH

说明：  新一代的多媒体移动标准DVB—H是DVB—T在移动接收方面的扩展。针对移动接收的特点，DVB—H 提出 了几项颇受瞩目的新技术，实现了对手机等手持式移动终端接收地面数字广播电视信号的良好支持。包括降低能耗、无缝切 换、提高移动环境中的抗干扰能力以及灵活的组网方案等。介绍了DVB—H的系统结构，详细讨论了DVB—H标准中数据 链路层的时间分片(time slicing)和多协议封装一前向纠错(MPE—FEC)技术，并给出一些实验环境下的定量分析。
(A new generation of multimedia mobile standard of DVB-H is a DVB-T in mobile reception expansion. Characteristics for mobile reception, DVB-H made a number of popular attention of the new technologies, to achieve a hand-held mobile phone and other mobile terminals to receive terrestrial digital broadcasting television signals of good support. Including lowering power consumption, seamless switching, enhance the mobile environment of anti-interference ability and flexible networking solutions. Introduce a DVB-H system structure, a detailed discussion of the DVB-H standard in the data link layer time slicing (time slicing) and Multi-Protocol Encapsulation Forward Error Correction 1 (MPE-FEC) technology, and gives some Experimental quantitative analysis environment.)
