Key takeaways
- DVB covers physical transmission via terrestrial, satellite, or cable.
- OTT delivers video over the internet using HTTP protocols.
- Broadcasters use DVB for reach and OTT for interactivity.
- Flicknexs supports OTT delivery, not DVB transmission.
How DVB works
DVB standards define the physical and data link layers for broadcasting. They specify how MPEG-2 or MPEG-4 streams are packetized and modulated for specific media. DVB-T targets terrestrial antennas. DVB-S uses satellite downlinks. DVB-C operates over coaxial cable. Each variant uses specific modulation schemes, such as QAM or QPSK, to maximize data throughput on that medium. The receiver, usually a set-top box or TV tuner, demodulates the signal and decodes the video. This is a one-way broadcast model. The sender pushes data to all connected receivers simultaneously. There is no feedback loop from the viewer to the server. This structure makes DVB efficient for linear channels but limited for on-demand or personalized content. Operators must maintain separate infrastructure for DVB transmission and OTT delivery. The two systems do not share the same delivery path.
Why DVB matters for a streaming business
Many legacy broadcasters still rely on DVB for their primary audience reach. If you run a streaming service for a broadcaster, you need to understand this split. The DVB side handles the linear, mass-market channel. The OTT side handles the app-based, interactive experience. Operators often face pressure to migrate away from DVB due to rising infrastructure costs and the shift to mobile viewing. However, DVB remains relevant in regions with poor internet connectivity or for emergency alerting. Understanding DVB helps you explain why a broadcaster cannot simply turn off their transmitters. It also clarifies why content must be encoded and packaged separately for each delivery method. You manage the OTT platform, but the client manages the DVB headend. Clear boundaries prevent scope creep and technical conflicts.
DVB vs OTT
DVB and OTT serve different purposes in a modern media strategy. DVB is a broadcast standard. OTT is an internet delivery method. DVB uses multicast over specific hardware. OTT uses unicast over IP networks. DVB requires a tuner. OTT requires an internet connection. The table below highlights the core differences.
Common mistakes with DVB
- Confusing DVB with IPTV. DVB is broadcast. IPTV is unicast over IP.
- Expecting OTT platforms to manage DVB transmitters. This is a separate infrastructure layer.
- Assuming DVB supports on-demand viewing. It is designed for linear schedules.
- Ignoring the need for separate encoding profiles for DVB and OTT.
- Overlooking the latency differences between broadcast and internet delivery.
How Flicknexs handles DVB
Flicknexs does not provide DVB transmission services. It is an OTT platform built for internet delivery. If you are a broadcaster, you can use Flicknexs to deliver your linear channels and VOD library over the internet. You will still need a separate DVB headend and transmission infrastructure for your terrestrial, satellite, or cable feeds. Flicknexs handles the OTT side, including live streaming, VOD, and monetization. You manage the DVB side through your existing broadcast partners. This separation allows you to scale your digital presence without touching your physical broadcast hardware. For details on managing linear channels in an OTT context, see our Broadcast streaming software page.
