摘要

DVB-T2地面电视标准正变得越来越重要,并得到了广泛的研究和发展,以更高的频谱效率和更好的性能提供多种类型的业务。DVB-S2中的物理层管道是承载一个或多个业务的逻辑通道,具有调制方案和鲁棒性。主要的变化在物理层,其中DVB-T2合并了一个新的物理层管道(PLP)。每个物理层管道包含调制、编码和交错的单独配置。这个新概念允许使用多个物理层管道进行传输,其中每个服务可以使用不同的物理层配置进行传输。先进电视系统委员会(ATSC3.0)标准将增加广播服务的价值,通过增加新的商业模式,提供更高的质量,改进的可访问性,个性化和交互性,以及更灵活和有效地使用频谱,从而扩大覆盖范围。

Multiple Physical Layer Pipes performance for DVB-T2
The DVB-T2 terrestrial television standard is becoming increasingly important, and have been extensively studied and developed to provide many types of services with higher spectral efficiency and better performance. The Physical Layer Pipes in DVB-S2 are logical channels carrying one or more services with modulation scheme and robustness. The main changes are found in the physical layer where DVB-T2 incorporates a new physical layer pipe (PLP). Each physical layer pipe contains an individual configuration of modulation, coding and interleaving. This new concept allows a transmission with multiple physical layer pipes where each service can be transmitted with different physical layer configuration. The Advanced Television Systems Committee (ATSC3.0) standard will add value to broadcasting services, allowing a extending reach by adding new business models, providing higher quality, improved accessibility, personalization and interactivity and more flexible and efficient use of the spectrum.
