IPTV industry is following a really complex chain in comparison to its relative “traditional” industrial fellows who are offering the same services that they do. IPTV has been termed as the most secure and consistent delivery of entertainment and videos to the subscribers. What do these services include? Your Live TV, Interactive TV and Video on Demand; all is a part of the services that the set-top box manufacturers provides to you.
Even when the concept of what an IPTV manufacturers are offering you seems quite simple and clear, the system of this industry is extremely comprehensive and not that simple at all. To get the IPTV system right and to get comprehensive solution for it all, there are some really important features needed to make the IPTV system run properly.
- TV Head End:
The TV Head End is the station where all tasks such as encoding, encryption, delivery of IP multi-task stream and recording takes place.
When you are watching something on the TV that is being delivered by an IPTV system, it all reaches you through the TV head end.
- Interactive Portal:
Interactive portal is basically the graphical user interface and is also known as the middleware. The graphical user interface is actually what the viewer’s view. So what is it that makes up the middleware? The visual guide, electronic program guide and navigation make up the middleware. This is all with the help of which the viewer interacts with the TV.
- Resource Management:
Resource management is done through the application server which is hardware, important for the smooth running of the IPTV system. Through resource management, the IPTV system is able to keep record of different things like the customer privileges and the utilization of content information etc.
The application server is responsible for keeping a proper record of all the necessary data for managing the end points of the IPTV system. It is also responsible for giving them the required rights.
- Video On Demand (Optional):
This feature of the IPTV system is optional. Video on demand content is actually the stored content which is transported to the viewers, whenever they pick a unicast from the server. A lot of people might not know about unicast; it is a one to one stream of the video on demand content, which is displayed when the viewer chooses a specific program: a movie that they want to watch on demand is a perfect example for this.
This is extremely important feature of an IPTV system as this is what carries the content to the viewer’s home. Or you can simply say that it delivers the content from one end to the other end. If we look specifically into the IPTV system, the gateway will be the viewer’s home router.
