The DVB Project has announced a major milestone with the success of the first live transmission employing DVB-C2, the new second-generation baseline transmission system for digital television via cable networks, at Germany's Technische Universitaet Braunschweig.
DVB-C2 employs the latest modulation and coding techniques to enable highly efficient use of cable networks. It offers a range of modes and options that can be optimised for the different network characteristics and the requirements of the different services planned for delivery to cable customers. According to the DVB project office, it offers greater than 30% higher spectrum efficiency under the same conditions as today's DVB-C deployments.
After analogue switch-off the cable networks can be optimised for digital transmission. This will result in a capacity increase of about 60% for DVB-C2 as compared to DVB-C.
Prof. Dr.-Ing. Ulrich H. Reimers, Institut fuer Nachrichtentechnik, Technische Universitaet Braunschweig and Chairman, DVB Technical Module commenting on the significance of the first live DVB-C2 broadcast said, "DVB-C2 is the third of the second generation DVB broadcast standards—after DVB-S2 and DVB-T2.
It is a radically new system which includes a huge number of innovations. The performance of DVB-C2 is so excellent that it is hardly possible to devise an even better standard in the future. Up until now, our knowledge about the features and performance of DVB-C2 was based on simulations. I am extremely pleased that my team has now concluded our development of a real DVB-C2 chain. This chain demonstrates that DVB-C2 can be implemented practically and it gave us the opportunity to prove that the predictions for the system's performance were correct".
