…regional adaption in DVB-T/T2 Single Frequency Networks. Where terrestrial network operators face particular challenges in frequency availability, today’s favored approach is to deploy cost and frequency efficient SFNs. There has, however, been a trade-off. SFN operation significantly impacts the operator’s ability to insert local content to a national TV service. The launch of the T-VIPS CP330 offers a flexible solution for operators to cost-effectively insert local content in SFN networks, easily. The CP330 T2 Bridge has been field-tested at major DVB-T2 reference sites and is ready to ship.

The CP330 offers network operators great flexibility both in how they design their distribution networks and how they insert regional and local content. The T2 Bridge enables the distribution of signals to digital terrestrial transmitters using satellite or hybrid (satellite, fiber and microwave) infrastructures. With the T-VIPS CP330, it is now possible to reuse a DTH satellite signal to directly feed terrestrial transmitters. By using the DTH satellite and the advanced deterministic multiplexing processes of the CP330, terrestrial operators now have a highly cost-effective distribution solution that is SFN compliant. The main advantages of the CP330 are:

• Available in different modes for maximum flexibility
• Support for deterministic remultiplexing, which creates identical signals at all transmitter sites in the same region, and offers the flexibility to implement a centralized model or carry out local insertion at transmitter sites
• Support for Multiple Physical Layer Pipes (MPLP), enabling adaptation through PLP replacement in the region – an alternative approach for complying with SFN requirements
• Increased reliability through integration with T-VIPS’ TNS541 and TNS544 seamless switches
• Smart PSI/SI processing to deliver a correct and complete EPG

“Up until now DVB-T2 operators have been unable to effectively utilize DTH satellite signals for primary distribution to SFN transmitter sites. That changes with the launch of the T-VIPS CP330.” said Johnny Dolvik, CEO, T-VIPS. “With support for PLP replacement and deterministic remultiplexing, T-VIPS solves the issues of localizing a DTT offering while maximizing efficiency through SFN operation. Most important of all the CP330 allows operators to do this at the same time as utilizing the DTH satellite signal. We believe that this significant leap in flexibility and efficiency will make the CP330 an important part of the DTT operator’s toolkit.”
