摘　　要：本文介绍我国新一代卫星直播系统,即先进卫星广播系统(ABS-S)。该系统具有的系统性能及提供的业务完全适合未来卫星广播的各种需求。本文分析ABS-S的基本特征及系统性能,基于试验室及现场测试数据,证明了ABS-S系统的先进性。ABS-S系统明显优于目前广泛使用的卫星电视广播标准DVB-S,同时和第二代直播卫星电视广播标准DVB-S2相比,具有等同的性能,且具有更低的系统实现复杂度。最后,介绍了ABS-S系统的产业化推进及应用情况。The ABS-S technical specification is the first important proprietary technical specification that is independently developed in the China’s radio and TV system since the founding of the PR of China,which marks a transition of scientific researches in China’s radio and TV system from exclusive investigation and study to innovation. Experiments show that the ABS-S system is obviously superior to the DVB-S widely used at present and has the same performances as the DVB-S2 has,but a lower complexity of its system implementation. An analysis of ABS-S’ basic characteristics and performances is made,its laboratory and field test data and an introduction to promotion of its industrialization and application are given.
