DVB-T2 the second generation of terrestrial broadcasting is available for some years and has already been introduced in many European countries. Similarly in North America, the next generation of terrestrial broadcast - ATSC 3.0 - is also under development. [More]

DOCSIS 3.1 is the latest generation of the “Data Over Cable System Interface Specification”. DOCSIS systems are used in many countries worldwide and provide high speed internet access via “hybrid fibre/coax” cables — formerly known as TV cables. The recent enhancement DOCSIS 3.1 shall provide exceptionally high data rates of up to 10 Gbit/s for downstream transmissions and 1 Gbit/s for upstream transmissions.
In cooperation with the companies IAF and KWS, the Institute for Communications Technology develops a DOCSIS 3.1 measurement receiver. The project is supported by the German Federal Ministry for Economic Affairs and Energy.

"Dynamic Broadcast" refers to a research field aimed at making TV broadcast transmission dynamic. In contrast to conventional broadcast systems, in Dynamic Broadcast, we assume that, in addition to a broadcast network, there is an alternative broadband network available for the delivery of TV content.  [More]

DAB/DAB+ was developed when commercial radio broadcast in Europe had only just began. Especially topics as local advertisement and introduction of local radio stations were not yet considered. An important strength of DAB/DAB+ is the option to realize extensive broadcast networks using the same frequency (Single Frequency Network - SFN). The SFN concept is in contrast to local advertisement and other local services, which do not send the same data in an SFN, but rather send different data from different transmission sites. In DVB-NGH (Next Generation Handheld) Local Service Insertion was considered. Thereby options were created allowing local services in SFNs. In this project an extension of DAB/DAB+ is planned, for which a technique and realization for local service insertion providing best possible compatibility has to be found. [More]

In our opinion the goals of the energy transition in Germany can only be reached, if the citizens are integrated into this process and can start conserving energy on their own. [More]

The term Tower Overlay over LTE-Advanced+ describes a research project started in 2011. It aims at relieving cellular networks from popular content (e.g. videos) and reducing the overall operational costs by utilizing broadcast transmissions. This is done by the use of a "classical" broadcast infrastructure - high transmission towers with a high transmission power (HTHP). The transmitted broadcast carrier can be seen as an overlay to the mobile cellular network. [More]
