充分利用新频谱，下一代地面数字电视广播规格DVB-T2即将诞生！

据编写地面、卫星和有线数字电视广播标准的数字视频广播（DVB）组织执行董事Peter MacAvock表示，该组织将于2008年初发布名为DVB-T2的下一代地面数字电视广播规格。  

MacAvock在日前举行的国际广播会议上表示，数字视频广播领域正在发生着日新月异的变化。新的DVB-T2标准将是一个突破性的系统，而不仅仅是在现有的DVB-T标准上作一些小小的修改。  

由于目前仍处于讨论阶段，MacAvock拒绝透露即将问世的DVB-T2标准的构建块。但他表示，DVB组织已经重新打开了潘多拉的盒子。从扩展频谱、单载波系统到更先进的单通道和多通道正交频分复用，甚至是中国的DMB-TH，DVB组织在考虑每一个标准作为DVB-T2的可能候选。  

推动DVB组织开发DVB-T2的原因，是由于模拟电视广播让位于数字电视之后空出的新频谱。  

DVB组织希望给广播公司提供“能充分利用一个新释放的频谱的最好技术。”  

DVB-T2将与现有的地面DTV标准DVB-T共存，让广播公司能够提供各种新的服务，包括“超级移动电视、多媒体频道和HDTV。”  

DVB组织给DVB-T2规格加入了更多的智能和高端技术，以期使之成为管理机构眼中利用新频谱的最好选择。  

DVB组织将在明年第一季度完成DVB-T2的首份草稿。据MacAvock估计，基于该规格的消费产品开发将于2009年晚期到2010年早期开始。
