DVB-T and DVB-T2 Transmitter Test Challenges
Application Notes
Introduction
Over the past 10 years, DVB-T has become the most widely adopted and deployed terrestrial digital video standard. It is now well established and the prices of DVB receivers have dropped over time as the technology has matured. Due to its successful development and deployment, DVB-T has come to serve as a sort of benchmark for the development of other terrestrial digital video standards.
Due to increasing scarcity of spectrum and requirements for high transmission capacity in recent years, an updated standard with more spectral efficiency is required to replace DVB-T. The DVB-T2 system is capable of meeting these requirements, due to its increased capacity, robustness, and the ability to reuse existing reception antennas. The regions which previously adopted DVB-T systems, primarily countries in Europe and Asia, will be migrating to DVB-T2, while many new countries and regions began the process of adopting DVB-T2 directly since the first version of the standard was published in 2009.
