“…It was originally proposed in the DVB-T2 standardization process, but was finally made an informative part of the standard (not normative) due to the need of implementing two tuners in the receivers 4 . DVB-NGH adopted TFS for all profiles because it can be operated with a single tuner without adding excessive receiver complexity.…”

FOBTV-13-01 1Abstract-This paper reviews the main technical solutions adopted by the next generation mobile broadcasting standard DVB-NGH, the handheld evolution of the second generation digital terrestrial TV standard DVB-T2. The main new technical elements introduced with respect to DVB-T2 are: layered video coding with multiple physical layer pipes, time-frequency slicing, full support of an IP transport layer with a dedicated protocol stack, header compression mechanisms for both IP and MPEG-2 TS packets, new LDPC coding rates for the data path (down to 1/5), non-uniform constellations for 64QAM and 256QAM, fourdimensional rotated constellations for QPSK, improved time interleaving in terms of zapping time, end-to-end latency and memory consumption, improved physical layer signaling in terms of robustness, capacity and overhead, a novel distributed MISO transmit diversity scheme for SFNs, and efficient provisioning of local content in SFNs. All these technological solutions, together with the high performance of DVB-T2, make DVB-NGH a real next-generation mobile multimedia broadcasting technology. In fact, DVB-NGH can be regarded the first third-generation broadcasting system because it allows for the possibility of using multiple input multiple output MIMO antenna schemes to overcome the Shannon limit of single antenna wireless communications. Furthermore, DVB-NGH also allows the deployment of an optional satellite component forming a hybrid terrestrial-satellite network topology to improve the coverage in rural areas where the installation of terrestrial networks could be uneconomical. to Handheld) [4], were developed to support large scale consumption of mass multimedia services such as mobile television (TV). However, the adoption of mobile TV services did not fulfill the initial expectations due to the lack of a successful business model and the high costs associated to the deployment of new mobile broadcasting networks. Today, a new generation of mobile broadcasting technologies is emerging due to the continuously increasing requirements and expectations of both users and operators, incorporating the latest advances in wireless communications which provide significant capacity and coverage performance improvements compared to first generation mobile broadcast systems. IndexDVB-NGH (Next Generation Handheld) [5] is the handheld evolution of DVB-T2 (Terrestrial 2nd Generation) [6], the most advanced digital terrestrial TV (DTT) technology in the world, offering more robustness, flexibility and at least 50% more spectrum efficiency than any other technology [7].DVB-NGH was created with the objective of becoming the reference mobile multimedia broadcasting standard. However, DVB-NGH not only succeeds significantly outperforming existing mobile broadcasting technologies in terms of capacity and coverage, but also optimizing DVB-T2 in many aspects. Furthermore, DVB-NGH is the first broadcasting system to incorporate Multiple-Input Multiple-Output (MIMO) antenna schemes as the key technology to overcome the S...
