中文摘要：

研究了下一代数字电视广播标准中输入格式处理技术,重点关注扩展输入格式、提高封装效率、增强传输功能三个方面.提出了一种因特网协议（IP）数据包的直接封装与传输方法,还提出了一种具有更高封装效率的包头压缩方法.理论分析与仿真表明,在传输IP数据包时,新方案提出的直接封装方案能够提高传输效率约2％,提出的IP数据包包头压缩方法能够提高封装效率0.3％-1.3％.

英文摘要：

Input formatting technology for next generation digital television broadcast is studied. Three aspects are emphasized including extension of input formats, increase of encapsulation efficiency and enhancement of delivery functions. A direct Internet Protocol datagram encapsulation and delivery method and a new IP header compression method with higher compression efficiency are proposed. Theoretical analysis and simulation show the new direct encapsulation method can provide 2% increase of efficiency, and the new header compression method provides further 0.3% - 1.3% increase of efficiency.
