IPTV works by delivering television content over the internet using Internet Protocol (IP) networks, instead of traditional cable or satellite signals. Content is processed and sent to servers, which then stream it to a user's device via a broadband connection. This requires a stable internet connection, a compatible device (like a TV with a set-top box, a smart TV app, a smartphone, or a tablet), and often a subscription to an IPTV service.
How the content gets to you
- Content sourcing: Providers gather content from sources like live broadcasts and video libraries.
- Content processing: The video and audio are compressed and encoded into data packets that can be sent over the internet.
- Content delivery: These data packets are transmitted from the provider's servers to your device through your broadband internet connection.
- Content reception: A set-top box or app on your device receives the data packets and reassembles them to display the video.
Key differences from traditional TV
- Transmission method: IPTV uses the internet (IP networks), while traditional TV uses coaxial cables (cable) or radio waves (satellite).
- Flexibility: IPTV is more flexible, as content can be watched on multiple devices like smartphones and tablets.
- Delivery model: IPTV uses a client-server model, similar to how websites and email work, whereas traditional TV uses a broadcast model.
Types of IPTV
- Live TV: Broadcasts content in real-time.
- Time-shifted TV: Allows users to watch content after it has aired, such as "catch-up TV".
- Video on Demand (VOD): Lets users choose and watch content, like movies and shows, whenever they want.
- Near Video on Demand (nVoD): A pay-per-view model for specific content that is available at a limited set of times.
