通过10GHz以下的多点视频分配系统(MVD)分配数字多节目电视(TV)/高清电视(HDTV)的调制和信道编码系统。本ETS中描述的系统基于ETS 300 429中描述的电缆系统的帧结构、信道编码和调制。频带可能/将在CEPT内协调。该系统适用于不同的MVDS发射机带宽。提供了与运动图像专家组2(MPEG-2)编码电视服务(见ISO/IEC IS 13818-1)的兼容性,传输结构与分组复用同步。利用多路复用的灵活性,可以将传输容量用于各种电视服务配置,包括声音和数据服务。所有服务组件都在单个数字载波上进行时分复用(TDM)。
Modulation and channel coding system for the distribution of digital multi-programme Television (TV)/High Definition Television (HDTV) by Multipoint Video Distribution Systems (MVDS) below 10 GHz. The System described in this ETS is based on that described in ETS 300 429 on framing structure, channel coding and modulation for cable systems. The frequency band may/will be harmonised within CEPT. The System is suitable for use on different MVDS transmitter bandwidths. Compatibility with Moving Pictures Experts Group-2 (MPEG-2) coded TV services (see ISO/IEC IS 13818-1), with a transmission structure synchronous with the packet multiplex, is provided. Exploitation of the multiplex flexibility allows the use of the transmission capacity for a variety of TV service configurations, including sound and data services. All service components are Time Division Multiplexed (TDM) on a single digital carrier.
