Dynamic Broadcasting: a revolution for broadcasting?

Ulrich Reimers (TUBS, Former Chair DVB Technical Module) shows at DVB World 2013 his conviction that Germany will not adopt DVB-T2 but will opt for hybrid alternatives on LTE networks.

The second day of DVB World 2013 began with a survey among attendees in which they were asked if they consider that there will be new digital terrestrial television systems in the medium-term future, let's say a DVB-T3... 60% have been convinced that there will be no such advance.

Ulrich Reimers (TUBS, Former Chair DVB Technical Module) has referred to the impossibility of Germany, a country with a very strong presence of cable and little relevance of DTT, to adopt DVB-T2. Reimers has wondered about the probability that this decision by large German broadcasters such as RTL could cause a domino effect throughout Europe.

One option that the Germans would be considering would be to use the UHF spectrum to develop a Dynamic Broadcasting concept. It would be a combination between the DTT concept that we have today and the new LTE networks. Another option would be the use of multicast Internet (eMBMS), although it would encounter the obstacle of the speed differences in data reception presented by each user.

Reimers concluded his speech by assuring that there is no proven technology yet for the provision of services equivalent to broadcasting: neither unicast LTE nor eMBMS.

This expert would lean more towards a solution that he has called Tower Overlay over LTE, which would involve using DVB-T2 as an LTE carrier.

Ulrich presented a new configuration called “Tower overlay over LTE,” which may be able to provide the solution. DVB-T2 could act as a carrier for LTE. Some band plans have been devised that might accommodate this.
