DVB-T2 is offering a new way for broadcasting value-added services to end users, such as High Definition (HD) TV and 3D TV. Thanks to the advances made in digital signal processing, and specifically in channel coding, DVB-T2 brings an increased transfer capacity of 50% and a new flexibility in services' broadcasting in contrast with the first generation DVB-T standard. As DVB-T2 is still in deployment's test, simulation model could be an interesting way to evaluate the performance of this network in supporting new value-added services. In this paper, we describe the new features and enhancements we have integrated within the DVB-T2 module in OPNET, and in particular: (i) realistic physical model; (ii) MPEG-TS layer with an IP encapsulator; (iii) hierarchical application layer ables to use pcap traces to simulate real video traces. Finally, we validate the developed DVB-T2 model according to the standard recommendation in terms of physical layer performance (BER versus SNR).
