Despite the dominance of IPTV and streaming, DVB-C remains a sought-after solution in many areas. Network operators, utility companies and municipalities in particular continue to rely on this proven technology.
DVB-C uses the coaxial network for TV distribution. This is already available in many regions. Operation is stable and independent of bandwidth or network bottlenecks. DVB-C is particularly impressive in linear television with low latency and consistent quality.
Advantages at a glance:
- Use of existing coaxial cabling
- No need to set up complex IP infrastructures
- Televisions with tuner work immediately
- No network load due to multicast
- Low maintenance costs and high operational reliability
HF overlay as a solution for existing infrastructures
One current approach is the combination of IPTV and DVB-C using so-called RF overlay systems. Here, the high-frequency (HF) signal is not first processed IP-based, but is optically modulated directly and transported to the property via a fiber optic connection. There it can be distributed as usual to all TV endpoints via the existing coaxial network.
HF overlay allows modern IPTV infrastructure to be connected to the existing building cabling. Network operators can manage the signal centrally, while no complex IP distribution is required in the property. The solution remains technically lean for owners and operators. No new end devices, no multicast equipment and no complex network planning are required.
This combination is particularly useful in environments with many reception points. In addition, the technology is already available in many buildings so that existing infrastructure can be easily accessed.
DVB-C for municipalities, energy suppliers and regional network operators
Many municipalities and local utility companies operate their own infrastructures or offer TV services via existing networks. DVB-C offers a stable basis for reliably supplying households. Especially in regions with a mixed network structure or limited technical resources, DVB-C provides an economically viable solution.
The existing coaxial cabling can continue to be used. Distribution within buildings is possible without technical know-how and there are hardly any ongoing operating costs. At the same time, the signal can be maintained and expanded centrally, for example by adding new channels or IP-based additional services.
However, this also results in limited monetization opportunities. The monthly income per household is often low, especially if the TV signal is charged at a flat rate or cross-subsidized via cooperatives. At the same time, infrastructure, maintenance, signal processing and license costs have to be covered. In many cases, this leads to narrow or even negative margins. This means all the more that the DVB-C offer and the TV signals must be delivered efficiently.
Conclusion: Technically solid but efficient implementation necessary
DVB-C is not an outdated technology, but continues to fulfill a clear purpose. In scenarios where stable, uncomplicated and economical TV distribution is required, DVB-C remains the right solution. Existing infrastructures can continue to be used and technical hurdles can be avoided.
In conjunction with HF overlay, modern requirements for platform control and flexibility can be combined with simple distribution in the building. This combination is in active demand today.
Netstream supports network operators, municipalities and building administrations in the planning and implementation of such solutions. Our experience shows: DVB-C continues to be a reliable basis for those who focus on quality and efficiency.
