Despite the dominance of IPTV and streaming, DVB-C remains a sought-after solution in many areas. Network operators, utilities and municipalities in particular continue to rely on this proven technology.
DVB-C uses the coaxial network for TV distribution, which already exists in many regions. Operation is stable and independent of bandwidth or network bottlenecks. In linear TV in particular, DVB-C stands out with low latency and consistent quality.
Benefits at a glance:
- Use of existing coaxial cabling
- No need to build complex IP infrastructure
- TVs with a tuner work straight away
- No network load from multicast
- Low maintenance costs and high operational reliability
RF overlay as a solution for existing infrastructures
One current approach is to combine IPTV and DVB-C using so-called RF overlay systems. Here, the radio frequency (RF) signal is not first processed over IP but modulated optically and transported into the property via a fibre connection. There it can be distributed to all TV outlets via the existing coaxial network as usual.
RF overlay makes it possible to connect modern IPTV infrastructure with existing building cabling. Network operators can manage the signal centrally, while no complex IP distribution is needed in the property. For owners and operators, the solution remains technically lean. No new end devices, no multicast set-up and no complex network planning are required.
This combination makes particular sense in environments with many reception points. In addition, the technology is already in place in many housing developments, so existing infrastructure can easily be used.
DVB-C for municipalities, energy utilities and regional network operators
Many municipalities and local utilities run their own infrastructure or offer TV services over existing networks. DVB-C provides a stable basis for reliably supplying households. Especially in regions with a mixed network structure or limited technical resources, DVB-C enables 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 extended centrally, for example with new channel offerings or IP-based additional services.
However, this also results in limited monetisation opportunities. Monthly revenue per household is often low, particularly when the TV signal is billed at a flat rate or cross-subsidised via cooperatives. At the same time, infrastructure, maintenance, signal processing and licence costs have to be covered. In many cases, this leads to slim or even negative margins. All the more reason why the DVB-C offering and the TV signals have to be delivered efficiently.
Conclusion: technically solid, but efficient implementation is needed
DVB-C is not an outdated technology; it still serves a clear purpose. In scenarios where stable, straightforward and economical TV distribution is needed, DVB-C remains the right solution. Existing infrastructure can continue to be used and technical hurdles avoided.
Combined with RF overlay, modern requirements for platform control and flexibility can be combined with simple distribution within the building. This combination is in active demand today.
Netstream supports network operators, municipalities and property management companies in planning and implementing such solutions. Our experience shows that those who focus on quality and efficiency still find a reliable foundation in DVB-C.
