Description
The CP560 DVB-T2 Gateway consists of a powerful and reliable rack unit, particularly
addressing the needs of system integrators and transmitter manufacturers to enhance
their existing DVB-T2 product range with the “must-have” DVB-T2 gateway.
Indeed, the CP560 DVB-T2 Gateway provides all the required features to run DVB-T2 in
a Single Frequency Network (SFN) mode in the context of trials as well as commercial
network roll-outs. Located at the network head-end, the CP560 DVB-T2 Gateway can
easily interface with existing service multiplexers via ASI or IP connections and is responsible
for preparing and generating the T2-MI stream (DVB-T2 Moduator Interface).
Best of class technology to operate DVB-T2 in SFN
In contrast with DVB-T, where a very simple MIP Inserter is required, DVB-T2 SFN operation requires more complex processes to be carried out at the head-end. Such processes includes MPTS stream over DVB-T2 Base-Band frames encapsulation, layered modulation stream mapping (so called Multi-PLPs), DVB-T2 signalling insertion, DVB-T2 SFN stream timing and T2-MI packet transmission over ASI or IP interfaces. In addition to those basic features, the CP560 DVB-T2 Gateway provides the capability to manage a T2-MI stream seamless switch-over for robust network operations and the possibility to remoy control the entire DVB-T2 transmitter network from a central point.
Already proven solution for DVB-T2
The CP560 DVB-T2 Gateway has already been chosen by early DVB-T2 broadcasters for their commercial network roll-outs as for instance in Finland and in Sweden. One of the main advantages of the CP560 DVB-T2 Gateway is its very reliable hardware design (non PC-based!) that supports state-of-the-art DVB-T2 features. Used in combination with TeamCast DVB-T2 modulators, broadcasters can take advantage of an already proven turn-key DVB-T2 transmission solution, reducing system integration complexity, avoiding interoperability issues and enabling DVB-T2 On-Air transmission in a very short time!
