我国数字电视地面传输标准一直是大家争论的焦点,而日前国家标准化管理委员会发布的DMB-TH标准将成为强制性国家标准,使这场长达5年之久的标准之争由此告一段落。DMB-TH标准的主要技术贡献者之一凌讯科技有限公司的共同创始人、副董事长和首席战略官董弘博士介绍说,目前国内已经使用的欧洲方案(DVB-T)、清华方案(DMB-T)和上海交大方案(ADTB-T)的地区必须在一年内转换成新的DMB-TH标准。他还透露指出,其实DMB-TH标准于半年前已经确定,主要以我国拥有自主知识产权的TDS-OFDM(时域同步正交频分复用)调制技术为基础,以多载波技术为主,融合了单载波技术,原有的清华方案的主要技术特点都会体现在
China’s digital terrestrial television transmission standards has been the focus of debate, and recently released by the National Standardization Administration DMB-TH standard will become a mandatory national standard, so that this up to 5 years of the standard dispute came to an end. Dr. Dong Hong, co-founder, Vice Chairman and Chief Strategy Officer of Legend Technology Co., Ltd., one of the major contributors to the DMB-TH standard, said that at present, DVB-T, Tsinghua University’s DMB-T) and Shanghai Jiaotong University program (ADTB-T) must be converted to the new DMB-TH standard within one year. He also disclosed that in fact, the DMB-TH standard was established six months ago mainly based on multi-carrier technology based on TDS-OFDM (Time Domain Synchronous Orthogonal Frequency Division Multiplexing) modulation technology with independent intellectual property rights in China. The integration of single-carrier technology, the original Tsinghua program’s main technical features will be reflected in
