DVB-T2 System and Network Design

DVB-T2 System and Network Design

Learning Objectives

This training course aims to provide theoretical and practical knowledge about the DVB-T2/Lite system, and how to build a transmission network. The course covers the complete distribution chain to network planning and implementation. After completing this course, delegates will understand the technology behind DVB-T2 system and have know how to plan and implement DVB-T2 networks. There is particular focus on SFN network design and implementation.

During the course, we also establish a “full” DVB-T2 distribution chain in order to demonstrate features of DVB-T2 and options in network deployment.
Parts of the content can be customised into an interactive workshop where the particular needs of your organisation are dealt with. This option is particularly useful for organisations before the actual deployment of a T2 network. This is one of our most appreciated courses.
