适用于卫星主天线电视（SMATV）系统的数字多节目电视传输系统提案。该ETS是对ETS 300 429（电缆）的补充，并与ETS 300 421（卫星）对齐。本ETS中描述的系统与通过有线和卫星传输的数字多节目电视使用的调制和信道编码系统兼容。该系统基于MPEG-2系统层，并添加了适当的前向纠错（FEC）技术。随着技术的进步，该系统允许进一步发展，目前能够启动可靠的服务。

Transmission System proposal for Digital multi-programme Television by suitable for distribution in Satellite Master Antenna Television (SMATV) systems. This ETS is complementary to ETS 300 429 (Cable) and it is aligned with ETS 300 421 (Satellite). The system described in this ETS is compatible with the modulation and channel coding systems used for digital multi-programme television by cable and satellite transmission. The system is based on the MPEG-2 System Layer, with the addition of appropriate Forward Error Correction (FEC) technique. The system allows for further evolution as technology advances and is capable of starting a reliable service as of now.
